Our aim is to broaden knowledge and understanding of one of the greatest natural treasures of Russia and of the world – Lake Baikal. Our principal audience is children who will increase their awareness and become more informed about Baikal and its environs thanks to this project. But these illustrated materials about Baikal's flora and fauna, its geography, and the people who live around it are more than an interesting source of information – they can also instill a feeling of love and pride towards our native region, and nurture an aspiration to protect the pearl of planet Earth, which is Lake Baikal, because we are ready to defend the things, which we love. The Baikal toolkit for schoolchildren includes: · a text book for students entitled, “Lake Baikal Box”; · game cards on the theme, “Living World of Baikal”; · a poster, “Above the Water and Under the Water”; · a map of specially protected natural territories, “Following Baikal's Nature Trails”; · a CD The text book consists of five parts: Part 1. Baikal: a Miracle of Nature Part 2. The Wonders of Baikal's Waters Part 3. Above the Water and Under the Water Part 4. Following Baikal's Nature Trails Part 5. It's interesting and entertaining Each part provides both information and creative assignments for children aged between 8 and 14. Teachers can adapt this information to suit various age groups, and pupils in sixth to eighth grades will be able to use the materials, and the Treasure Chest's “secret corners”, independently. By studying the information that is presented in the relevant parts and sections of the book, children will be able to carry out the assignments, which in turn will further strengthen their knowledge. All parts of the toolkit have cross-curricular content and can therefore be used for teaching various subjects, contributing to development of the general and special learning capacities of primary and middle school students. The creative assignments can be completed either individually, in pairs, in small groups, and, in some cases, with adults. They are designed to encourage the students to communicate interactively with their classmates and teachers, and to develop the subjective position of each student, in the hope of swelling the ranks of young environmentalists! Some tasks can be a basis for projects by the children. The toolkit can be adapted for different age groups depending on their level of preparedness, needs and interest, and also depending on the capabilities and experience of teachers. Materials can be used both in class and out of class in activities related to different subjects of the school curriculum. Lake Baikal Box can also be used as the basis for a separate optional course on the environmental problems of Baikal region, as well as a tool for studies and activities by naturalist groups. Our approach in creating the toolkit ensures flexibility in presenting and studying Baikal. Teachers are welcome to structure the materials depending on their preferences and on the classes where they use them. Parents and other adults who wish to use Lake Baikal Box as a means of home education can discuss its illustrations with children, read parts and sections of the book that are of particular interest to children together with them, and selectively work on assignments that are commensurate with their children's abilities. All of the first four parts of the text book offer various riddles, games, role plays, individual and group projects, experiments, and creative assignments in a section entitled, “Think, Play, Experiment, Create Together!”, which follows the informational sections.

They are grouped into the following categories: · Plants · Fish · Birds · Invertebrates · Mammals · Plants and animals of the Baikal shore This intriguing game will help young learners to consolidate their knowledge of Lake Baikal flora and fauna. Rules of the game and instructions for using the map of Baikal's nature reserves “Above Water, Under Water and on the Shore of Baikal ” are offered on the cards themselves. The Map of Baikal makes it possible to take a brief tour of the greatest lake on the planet. If you have never been to Baikal before, you can use the map to decided where you will go first. Most importantly, each time children use the map they will be reminded that there are specially protected nature reserves around Lake Baikal and that the Lake needs our protection. The Poster “Above the Water, Under the Water and on the Shore of Baikal” can be permanently exhibited in your classroom, to be used for specific tasks and when playing the card game. The educational materials portal about Baikal is a website, which will help both teachers and students who use this toolkit. It can be accessed at www.everydropmatters.ru You can download samples of all materials that are used in the toolkit from the website, and the site will be of use even if you do not have the kit. It will also be possible to play the game “Above the Water and Under the Water” online. Teachers, who register on the website, will receive a user ID and password. They can then share descriptive materials and upload pictures and videos of their assignments concerning Baikal. Teachers can also develop new materials, enabling us to fill the secret corners of Lake Baikal Box together.

Join the Island's name with its photograph • A mysterious archipelago. Answer the questions Where is Baikal? Baikal is located in the centre of Asia, in the southern part of Eastern Siberia, between Irkutsk Region and the Republic of Buryatia. The lake fills an ancient basin, which was created by a shift of the Earth's crust. Baikal extends from southwest to northeast for a distance of 636 km. Look carefully at the map of Russia and find where the world's deepest lake is located. In photos from space Baikal has the appearance of a huge crescent moon or an enormous banana. A few centuries ago, people had no concept of the outlines of Baikal. The first attempts to map the Lake were made at the end of the 17th and start of the 18th centuries, and the most accurate of them were by the Russian cartographer, geographer and historian of Siberia, Simeon Ulyanovich Remezov, in his Book of Maps of Siberia (1699–1701). Compare the image of Lake Baikal in the 17th century atlas with that on modern maps. 12 Baikal’s Birthday The age of Lake Baikal is of great interest to scientists, who now believe that the Lake is about 20–25 million years old. It is a very ancient lake. Other lakes live for about 15,000 years, before they disappear, but Baikal is still young – its area and its depth are still increasing, and the opposite shorelines are moving apart at a rate of 2 cm per year. The ecologists of Baikal region recently decided that our Lake deserves a birthday: every year since 1999, we celebrate Baikal Day on September 1. Why is our Lake called Baikal? The shoreline of Lake Baikal has been occupied by different peoples down the ages: Turkic tribes, the Mongols, the Evenks, the Buryats and the Yakuts. And each of them had their own name for the Lake. The origin of the name by which we know the Lake today – “Bajgal” or “Baikal” – is still subject to discussion. Some scholars believe that “Bajgal” is a Buryat word meaning “the natural sea”. Others maintain that this name was first given to the Lake by an ancient Turkic people, the Kuryks. Baj-Kul (Turkic) – “rich lake” Lamu (Evenk) – “sea” Tengis (Turkic) – “sea” Bejhaj (Chinese) – “northern sea” Bajgal-Dalaj (Mongolian) – “huge lake” Bajgal (Buryat) – “natural”, “real”, “existing”, Dalaj (Buryat) – “sea” Secret Corners of Lake Baikal Box The peoples who lived far from Baikal knew about the lake, too. In ancient Chinese manuscripts Baikal is called as “Bejhaj” that means “northern sea”. 13 Europe learnt of the existence of the Lake from Marco Polo's reports of his journeys. Other names for the Lake include the BuryatMongolian “Dalanor”, meaning “sacred lake” and “Llama”, which is the Tungus word for “sea”. Marco Polo (1254–1324) – the renowned Italian traveller and merchant of the 13th century, wrote the history of his 25 years of travels across Asia. The first Russian explorers of Siberia used the Evenk word “Lamu” to refer to the Lake. But in 1643 a group of 74 Cossacks led by Kurbat Ivanov arrived on its shores and took up the Buryat name, “Bajgal”. They Russianized the word, replacing “g” by “k”, to make “Baikal”, which is how the Lake is known today. V.Surikov. The Cossacs. A Sketch for the picture “Ermak’s conquest of Siberia”. Kurbat Afanasevich Ivanov (?–1666) – a Cossack from Tobolsk, is considered to be the the “discoverer” of Lake Baikal. He led an expedition from the Cossack settlement of Verkholensky, which brought Russians to the shores of the Lake for the first time. Some years after his expedition Ivanov created a map, which he called a “Drawing of Baikal and of the rivers that flow into it”. 14 People have called Baikal a “sea” since ancient times and this is the term used by the Old Believer, Avvakum, in his book The Life of Avvakum, the first literary work to mention the Lake, where he writes: “We mended the boat, set the sails, and went across the sea…”. Avvakum Petrovich Kondratyev (1620–1682) – was a church writer and head of the Old Believers. He crossed the Lake in July 1662, returning from exile in Dauria (now the region of Transbaikaliye). S. Miloradovich. Avvakum’s way in Siberia. 1898. In 1675 Nikola Milesku Spafary described the Lake as follows: “The Baikal sea remains unknown to chroniclers of past and present ages because […] to journey around it is impossible […] and its size, length, width and depth are great. And it can be called a lake because its water is fresh”. Local people still call Baikal “the sea”. Nikola (Nikolay Gavrilovich) Milesku Spafary (1636–1708) – was a Russian diplomat and scholar of Romanian origins. He crossed Baikal on his way to China, where he headed a Russian embassy. He gave the first detailed geographical description of Baikal. So Baikal has been an object of study for many centuries. The achievement of the earliest explorers was to discover the wonders of Baikal. Our task today is preserve these wonders for future generations. 15 The deepest lake… Baikal is the deepest lake in the world (1637 m). Its depth is explained by its geological origins. There are only two other lakes in the world with depth greater than 1000 m: Lake Tanganyika in Africa (1470 m) and the Caspian Sea in the south of Russia (1025 m). Find Lake Baikal, Lake Tanganyika and the Caspian Sea on the map of the world, and find out what continents they belong to. Baikal is the second biggest lake in Russia by the volume of water, which it contains: the Caspian Sea is larger by this measure. However, the waters of the Caspian are salty, while Baikal's water is fresh. The waters of Baikal represent 80% of all the fresh water in Russia and 20% of fresh water on the entire planet. The world's biggest lakes by surface area Name Area (sq. km.) Caspian Sea 371 000 Verkhneye 82 414 Victoria 69 485 Huron 59 500 Michigan 58 016 Tanganyika 32 893 Baikal 31 500 Bolshoye Medvejie 31 080 Niyasa 30 044 Aral Sea 13 900 Now look at the outlines of the Lake. In its widest place Baikal is almost 80 km across, and the distance from shore to shore at the narrowest place is almost 27 km. If we measure Baikal's surface area, we find that it is roughly equal to that of some countries (Belgium, for example). Baikal is one of the biggest lakes in the world. Look at the table. You can see that Baikal numbers among the ten greatest lakes in the world by surface area. 16 The mysterious depths of Baikal If we took all the water out of Baikal, you would find that the bottom of the Lake is a landscape of mountains and valleys. All this is concealed beneath a mass of water that is nearly two kilometers deep in places. Sazhen – a Russian linear measure equal to 2.13m Lot – ead weights with a thin rope or a cable Pood – a Russian measure of weight equal to 16.3 kg Since long ago people have aspired to knew more about Baikal. You have already learnt the names of some of these travellers and scholars from different ages and countries. In particular, people have wanted to know how deep the Lake is. Fishermen were probably the first to gain an idea of the depth of Baikal. Milesku Spafary spoke with local people and reports in his Travel Notes that “its depth is great because it has been measured with lines of a hundred sazhens and more, without reaching the bottom”. In the 18th century a German scientist, Peter Simon Pallas, make an expedition to Baikal and tried several times to find the bottom of the lake, but his 200m rope proved too short. In 1837 one of the exiled Decembrists Wilhelm Karlovich Kuechelbeker – a friend and a schoolfellow of Alexander Pushkin – carried out deep-water soundings in one part of Lake Baikal (the Barguzin Gulf). In 1859 deep-water soundings of the Lake were conducted by the Lieutenant Konstantin Kononov in preparation for the laying of a cable line from Kazan to the coast of the Pacific Ocean. Kononov used a rope one thousand sazhens long with an end-weight of one pood. 17 Secret Corners of Lake Baikal Box The scientific study of Siberia, including Baikal, began with the foundation of the Russian Academy of Sciences in St. Petersburg in 1725. The first scientific measurements of the depths of Lake Baikal were by the Polish scientists B.I. Dybovsky and V.A. Godlevsky, who did most of their work in the winter time. The fathometer (depth measurement instrument) which they invented is still used today with some improvements. In 1870, the two scientists were awarded the gold medal of the Russian Geographical Society for their research on Lake Baikal. Nowadays depth is often measured using a cable plummet or an echo-sounding device. Cable plummet (used in 1959). Measured depth of the lake = 1620 m Echo-sounding device (used in1974). Measured depth of the lake = 1637 m. A specialized institute – the Limnological Institute – is located in the village of Listvyanka, by the Lake, and is dedicated to studying all aspects of Baikal's ecosystem. Limnological Institute СО RAN, in Irkutsk The science, which studies lakes, is called Limnology. 18 The greatest depths of Lake Baikal The waters of Lake Baikal fill a natural depression in the earth's crust. The depression is divided into three large troughs – southern, middle and northern, – each of them separated by an underwater ridge. North Middle South The ridge, which divides the northern from the middle trough is called the Akademicheskaya (“Academic”) ridge. The middle and the southern troughs are separated by the SelenginoBuguldeisky elevation. Which of these parts of Baikal do you think is the deepest? • The deepest point in the southern trough of Lake Baikal, between the mouths of the rivers Pereyemnaya and Mishikha, is 1432m beneath the surface. • The water depth in the middle part of the Lake, near the eastern shore of Olkhon Island, between Capes Izhimey and Khara-Hushun, is 1637m. • The deepest point in the Lake's northern trough is off the coastal strip between Cape Elokhin and Cape Pokoiniki, where the water depth is 890m. So the deepest part of Lake Baikal is in its middle trough. The shallowest offshore point in Lake Baikal The shllowest depth of 34m was discovered by the scientist Gleb Yurievich Vereshchagin over the Posolskaya shoal, which is almost in the middle of the lake. 19 The mountains around Baikal Baikal is surrounded by the peaks and crests of mountains. We can find their names by studying the map. Try to find the Primorsky ridge on the map. It is located on the west side of Lake Baikal, and is of modest height – very few peaks along the Primorsky ridge rise higher than 1000 m. As you can see, the northern end of the Primorsky ridge rises to meet the Baikal ridge, which has peaks higher than 2000 m. The east coast of the Lake is girded by the Khamar-Daban mountain range, which is an offshoot of the Sayany mountains. Further to the north, beyond the river Selenga, you can see the low Ulan-Burgasy ridge, and along its northern part the Barguzin ridge has peaks as high as 2300–2600 m. Mountain systems around Baikal and their highest peaks Primorsky ridge Trekhgolovy Golets mountain 1746 m Ulan-Burgasy Khurkhan mountain 2049 m Khamar-Daban Khan-Khula mountain 2371 m Baikalsky Cherskogo mountain 2588 m Barguzin Baikal Peak 2840 m 20 In some places the mountain ridges descend straight to the water's edge, while in other places they are at a distance of several dozen kilometers from the shoreline. The slopes on the eastern side are gentle, but they are steep on the western side, with plentiful scree and pebble slides. The Baikal shoreline is also marked by valleys between the mountain ridges, the biggest of which are the Ust-Selenga, Ust-Barguzin and Upper-Angara valleys, containing the rivers which feed the Lake – the Selenga, Barguzin, Upper Angara and others. These valleys have traditionally been settled by people. The valleys and ridges around Baikal stretch for a distance of 2500 km and form the Baikal mountain region. 21 The islands and headlands of Lake Baikal Baikal has many islands and headlands (capes), but only one large peninsula, known as Svyatoy Nos (“Sacred Nose”). The largest of the islands on the Lake is Olkhon Island, which is located in the central part of the Lake and is considered to be its heart. Olkhon covers an area of 722.4 km2, it is 73 km long and 15 km wide. It coastline is gently sloping on the western side, but tall and steep on the eastern side. The part of Lake Baikal between its western shore and Olkhon Island is called the Small Sea. The south-western end of the Island is separated from the Baikal shoreline by a strait known as the Olkhon Gate, which is viewed by sailors as the most treacherous part of the Lake. The highest point on Olkhon Island is Izhimey mountain, the peak of which is located only 11 km from the Lake's deepest point – the 1637m depth, which we described above. Secret Corners of Lake Baikal Box The name of Olkhon Island is believed to come from the Buryat words “khoi” or”«khon”, meaning forest, or from “olkhon”, which means “dry”. Strong winds make it difficult for trees to take root on the Island, so they tend to grow alone or in small clumps, and the western coast is without any tree cover. 22 You might be interested to know what birds and animals live on the Island. You can see them and count them by looking at the pictures. Olkhon Island is home to various animals, including the lynx, fox, hare, squirrel, weasel, polecat and others, as well as one endemic species, the olkhon vole, which is only to be found in the steppes around Baikal. In winter time wolves sometimes cross the ice to the Island, but bears never go there. Baikal seals can sometimes be seen along the Olkhon coastline. Olkhon is the only island on Lake Baikal, which has been settled by people. Human habitation on Olkhon dates from the earliest times: scientists have found evidence of human presence (fragments of pottery and a crude knife) at one part of the Island – Saraisky Bay – dating from 13,000 years ago. About 1,500 people inhabit Olkhon today, and they live mainly from fishing and cattle breeding. 23 Not far from Olkhon we find the four Ushkany Islands. The Island are famous for their seal rookeries, and they have the curious names of “Big”, “Thin”, “Round” and “Long”. All of them are peaks of the underwater Akademichesky ridge. Why do you think the Ushkany Islands have these names? Can you imagine what they look like? Why would an island be called “Long”? Big Island rises out of the water in the form of a mountain 216 meters high, but the other three islands are not more than 17-22m above the water level. Big island has three caves at the foot of its limestone cliffs, in which archaeologists have found pottery fragments, other ancient remains, and seal bones, probably left behind by ancient seal hunters. Big Ushkany has huge 300 year-old larches and pine trees growing on its slopes and its rocks are entirely covered with brown moss. Big Ushkany is also remarkable for its thousands of ant hills, which are almost unique in Russia. Unfortunately, the ant population has been reduced in recent years by fires that have broken out on the Island. The Ushkany Islands take their name from the word “ushkan”, which is the Siberian word for a hare. But, strangely, there are no hares on the island. The name in fact comes from the north of European Russia where people on the coast of the White Sea call sea-seals “hares”, using the standard Russian word for a hare, which is “zayats”. When these people visited Baikal and saw seals on its islands, they therefore called the islands “zayachi” (this is the name used in Simeon Remezov's atlas of 1701). The local people then substituted their word for a hare, and the name “Ushkany” has stuck to this day. 24 Yarki Island in the northern part of Lake Baikal takes the form of a narrow sandy spit, stretching for 15 km along the northern shore of the Lake. The Island is covered with grass, birch trees and cedar scrub. Mountain pine Great Baklany (Shimai) Island, situated in the Chivyrkuysky Gulf of Lake Baikal, is a small rocky island, which used to be a nesting place for cormorants (“Baklany” in Russian) and is still inhabited by grouse. Larch trees spread from the highest point on the Island down to the water's edge, interspersed with glades. A sheer cliff rises from the Lake on the south-west of the Island.

What are these islands called? 3. What is remarkable about Yarki Island? 25 Cape Shamanskiy Many of the capes and headlands on the shoreline of Lake of Baikal take their names from the rivers and streams that flow into the lake. The names of some others have different sources. The best-known of Baikal's capes are Shamansky, Burkhan, Khoboy, and Kobylya Golova (“Mare's Head”). In fact, there are two Shamansky Capes on Lake Baikal, one of them in the northeast part of the Lake and the other in the south. The second Shamansky Cape deserves special mention, because it is often considered to be the gate to Lake Baikal. The Cape is near to the westernmost point of Baikal and extends into the Lake for half a kilometer. It is situated between the settlements of Kultuk and Slyudyanka and divides the southwest end of the lake into two parts, with Kultuk to the north and Slyudyanka to the south. The top of the rocky cape is covered with birch trees and resembles the whale from the Russian fairy tale “The Hump-backed Horse”. In the past the Buryats called this cape Aikha-Shulun , which means “Awful Stone”, reflecting the legends of shamans who carried out sacrifices and religious rituals here. Later Russian merchants used to make stopovers at the Cape, believing that by showing respect to the shaman's spirit they would ensure the success of their business affairs. Hence the name “Shamansky”. When you visit Baikal with your parents, take photographs of the Lake at different times of day and in different seasons. Collect the photos in an album and submit them for competitions or organize a photo exhibition in class. Secret Corners of Lake Baikal Box Cape Shamansky was the scene of an interesting scientific episode. In 1868 the scientists Benedict Dybovsky and Victor Godlevsky carried out observations of water levels and marked the high water mark on the side of the Cape. Their measurement proved significant because the water level in 1868 was the highest for 100 years. Unfortunately, the mark has not survived to the present (it was destroyed by explosives work during production of building materials). However, the work of the two researchers was continued by the scientist Ivan Chersky who made 16 water level marks at various locations around the Lake. Chersky's marks remain as a part of the history of scientific studies of Baikal. 26 The Sacred Nose Peninsula View at the peninsula from the place Karga Svyatoy Nos (“Sacred Nose”) is the biggest peninsula on Baikal and has the shape of a huge nose. The Buryat name, “Hilmen Khushun” means “face (nose) of a sturgeon fish”. The peninsula is 53 km long, and about 20 km across. Its western slopes are covered with dense taiga, and the eastern side has a number of sheltered bays and promontories. Find Svyatoy Nos Peninsula on the map (the photo from space will help you to find it). What islands can you see near the Peninsula? Several thousand years ago Svyatoy Nos was an island separated from the eastern shore of Baikal by a narrow strait. Two rivers, the Maly Chivyrkuy and the Barguzin, flowing into the Lake to the south of the island, gradually filled the strait with sand and silt, helped by regular storms on the Lake, until the island was connected to the mainland by a sandy spit and the strait was transformed into an inlet that we now call the Chivyrkuysky Gulf. There are three settlements on the peninsula: Monakhovo, Katun and Kurbulik. Show on the map where Peninsula Svyatoy Nos is situated. The photo made from space will help you in that. What other peninsulas have you noticed near the peninsula? In the place Monakhovo, in summer Tangles on western hill 27 Peninsula’s landscape 336 rivers flow into the Lake Baikal gathers waters from a huge territory and more than 336 rivers and streams flow into the Lake. The exact number cannot be established, because some of them dry up in years of low precipitation and reappear when the rains return. They include large navigable rivers: the Selenga, Upper Angara and Barguzin. Several more modest rivers the Kichera, Turka, Snezhnaya and Goloustnaya as well as many other streams that are shallow, and can be easily forded. View on the Selenga from the mountain Omulevaya The Selenga is the largest tributary of Lake Baikal, and accounts for half of all the river water flowing into the lake. The Selenga is 1024 km long and originates in Mongolia, from where it crosses the border into Russia and flows for 415 km across Buryatia to reach Baikal. The Selenga delta is of special interest, since it has pushed the waters of the Lake back some distance to the west. How has this happened? Many small mountain rivers carry large amounts of sand into the Selenga, some of which settle on the river bed, while the rest is carried into the Lake and sinks to the bottom. So a broad shallow area was created at the river delta and a huge flat expanse of dry land – the delta plain – was eventually formed. This new land is now occupied by meadows, fields and the villages of Kabansky district. Many of their inhabitants would find it hard to believe that the place where they now live was once covered by the waters of Baikal. The word “Selenga” is believed to derive from the Evenk word “sele”, meaning “iron”. 28 The water of the Selenga is muddy all the year round, especially during the summer. Why do you think this is? At the river's source, in the Mongolian steppe, there is a severe continental climate, almost no vegetation, and strong winds all the year round. The winds gather up small grains of sand, grind them to a powder and carry them for huge distances. Rainfall captures the dust and washes it into the tributaries of the Selenga. The Selenga's delta. View from the space. A delta is found at the mouth of the river, where it flows into a lake or sea, creating an areas of shallows thanks to the river deposits that are carried into the lake or sea. The Selenga's delta. Despite the slow current, this dust does not settle on the riverbed but flows all the way to Baikal. The muddiness of the Selenga is also explained by the fact that the river flows across a friable rock, called clay loam. A river bed is a deepening of the ground, a channel, along which a river flows. 29 The Upper Angara is the second full-flowing tributary of Lake Baikal. At the beginning of 17th century Russian explorers called it simply the Angara. But as there was another Angara (that flows out of Baikal), the river became known as the Upper Angara and this name has been preserved to the present day. The Upper Angara rises on the slopes of the Vitimsky Plateau and covers a distance of 452 km on its way to the Lake. Its mountain reaches are fast flowing with rapids, but the greater part of the river flows quietly through the marshy Angarsk depression. A variety of fish – taimen, grayling, burbot, ide, pike and perch – are found in its waters and the Arctic cisco uses the river for spawning. The Baikal-Amur railway runs along the banks of the Upper Angara. The word “anga” means “open” or “disclosed” in Buryat. The name Barguzin comes from the ancient tribe Barghouti, who lived in Baikal region. The Barguzin, the third largest tributary of Lake Baikal, is 400 km long, with turbulent upper reaches and a gentler flow as it approaches Baikal. In the far distant past a large mountain lake occupied the place of the lower reaches of the river . This ancient lake gradually diminished and disappeared, and the tributaries, which once flowed into it, came together in the Barguzin river. The villages of Barguzin district stand on what was once the bottom of the ancient lake. Smaller rivers, none of them longer than 170 km, also flow into the Lake. Can you find their names? Finally, a number of shallow, fast-flowing streams rise on the slopes of the ridges that form a dense ring around Baikal, and tumble down to the Lake below. 30 The Angara is the only river flowing out of Baikal Only one river, the Angara, flows out of Baikal. The Angara is 1 km wide and 4-6m deep at its start. The so-called Shaman's Stone , which is never covered by water, stands in the middle of the stream. This lone rock has been surrounded by legends since earliest times, and you can read about one them later in our Book: according to this legend, furious Lake Baikal threw the rock after his disobedient daughter, Angara, who had run away to her lover, Yenisei, without his permission. The head of the river Angara never freezes, and a steam rises from it throughout the winter. Why so? The waters that pour out from Baikal into the Angara do not come from the surface, but from the depths of the Lake, where the water temperature is above 0°C, and the fast current keeps the Angara headstream ice-free in even the coldest winters. This fact makes the head of the Angara the only refuge in northern Asia for wildfowl during the winter: black and white garrots, buff-breasted and common mergansers, and long-tailed ducks all winter here. All of the rivers that flow into Baikal, and that we discussed above, play a prominent part in the lives of the people who live around the Lake. Ancient culture instilled an attitude of respect towards the rivers, and to pollute or befoul them is still viewed as a great sin. Name the 10 tributaries of Lake Baikal. Choose one of the smaller rivers, which flow into Baikal. Find its course on the map and mark it on the contour map. Secret Corners of Lake Baikal Box The construction of three hydroelectric power stations on the Angara in the middle of the last century (Irkutsk, Bratsk and Ust-Ilimsk) has reduced the size of the ice-free zone by three times, and the number of wintering birds has reduced to 2000-3500. The birds start to arrive in November, by the beginning of December there are 1200-1500 ducks, and by the end of the month at least 2000 birds will have gathered. 31 Little lakes around Baikal There are a lot of smaller lakes in the region around Baikal – near to the Lake itself, in the surrounding mountains and at the feet of the mountains. Most of these lakes are under special protection, since they are the nesting places of migratory birds, including several rare and dwindling species. Lake Frolikha is a glacial lake situated in the high mountains of the Barguzin. It was formed during the last great glaciation of Baikal region when two large glaciers, which were moving down river valleys, collided and formed a dam, hollowing out the crater which contains the Lake we see today. Lake Frolikha is home to many fish including the taimen, goldilock, pike, grayling, Siberian roach, and darter. But it is most famous as the home of the Frolikh char, which is a rare fish found nowhere else in Siberia (except rarely in Baikal itself). The fish is included in the Red Book of Russia (1983) and of Buryatia (1988). The Russian word for the Frolikh char is “davatchan”, which is the Buryat word for “salmon”. This fish was once believed to be divine and any person who harmed it could expect divine punishment. Several of the plants around Lake Frolikha – the Baikal barotsenia, quillwort, alisma, and snowdon rose – are also included in the Red Book of Buryatia. Lake Guitara Lake Sobolikha Lake Vokinda Arangatuy is a large lake situated on the neck of the Svyatoy Nos Peninsula and linked by a narrow channel to Baikal's Chivirkuysky Gulf. Arangatuy is surrounded by a marsh where birds gather in the spring and fill the air with noise: swans, herons, divers and Eurasian curlews all fly to Arangatuy to nest. The waters of the Lake are rich in fish, including dace, orfe, carp, pike and darter. The name “Arangatuy” derives from the Buryat word “aranga”, meaning a “platform” or “tower on posts”, which was traditionally used by the Buryat;s when hunting for wild animals or storing food in the forest. 32 Another large lake, Kotokel, is situated in just 2 km from Baikal and connects with it via the Kotochik river, but is outside the Baikal nature reserve. The Lake is 14 km long and 5 km wide and includes Monastyrsky Island. An environmental disaster, which occurred some years ago, killed most of Kotokel's fish, seagulls and ducks, as well as the Baikal otters living along the Lake shore. Island Monastirsky The origin of the Lake's name is uncertain: “koto” in the Evenk language means a knife or club, which is used to clear small trees and make a path. Another explanation is associated with a type of footwear, “koti”, which Russians used for walking on marshy ground during wet weather.

Mark their location. 33 Proval Bay In the winter of 1862 a strong earthquake (10 points on the Richter scale) caused a large area of land near the estuary of the Selenga river to slip beneath the waters of Baikal. The resulting bay was called “Proval” (the Russian word can mean “fall” or “valley”). Human victims were few in number, but many nomad encampments were flooded and 1300 people were left homeless in the January cold, without their goods and livestock. The earthquake and subsidence was only subjected to scientific analysis two years later and many details of what happened are still not understood. The village of Oymur is located on the shoreline, close to Proval Bay. 34 Baikal's weather We are always interested to hear the weather forecast. So what is the weather like on Lake Baikal? Weather forecasters tell us whether to expect sunshine or rain, blizzards or even hurricanes. But any weather pattern is a combination of wind, precipitation, clouds and temperature. Meteorology (from Greek “meteoros” means a celestial and atmospheric phenomenon) is the science of the structure and qualities of the earth's atmosphere and its physical processes. It is also called the “physics of the atmosphere”, which gives a better idea of its character nowadays. Meteorologists build models to help forecast the weather and to carry out research into climate and the atmosphere using radar, satellites and other modern equipment. Average weather patterns are called climate, and different regions of the Earth have cold, temperate and hot climates. Baikal is located in a temperate climate zone with a sharply continental climate, which means that we have a cold winter and a short, hot summer, and that large temperature swings often occur through the day. But the enormous water mass of Baikal softens this continental climate, making it more like that of a region close to the sea. How does this happen? All through the summer the waters of the Lake soak up and store warmth. Then, in the late autumn and early winter, the Lake gives back this heat, tempering the harsh Siberian frosts. As a result the early winter temperature around Baikal is warmer than in regions further from the lake (until ice fully covers the Lake in January), but average temperatures near the Lake in summer are relatively low. Baikal has many sunny days (48 per year on average and 64 on Olkhon Island). 35 Precipitation over Baikal In June and July, when there is not much wind, a fog often settles over the Lake as warm land air spreads over the cold water surface. Fogs also occur in autumn and winter (from October–December until the Lake freezes over) when the air temperature is below zero but the water has a plus temperature. The weather on Baikal is full of surprises. In summer there may be heavy rainfall or drizzle that continues for several days, and in winter snowdrifts may grow to a height of several meters. A significant layer of snowfall can occur even in June: local people always say that June is not yet summer and July is no longer summer. The average annual volume of precipitation (rain and snow) over the vicinity of the Lake is 9.29 km3, accounting for about 13% of all the water input to the Lake. Most of the precipitation falls on the KhamarDaban coastline and in the mountains, while the Ushkany Islands and Olkhon are the driest parts of Baikal. People can enjoy pure blue skies over Baikal for most part of the year, since clouds do not form above the lake. This is because the water on the Lake's surface is too cold to evaporate and form clouds, while air masses that bring clouds from elsewhere towards Baikal take up warmth and disperse as they pass over the coastal mountains. 36 The winds of Baikal You know that air circulation over the Earth's surface is called wind. It can blow in any direction, and with varying force and speed. There is nearly always a wind blowing on Baikal, and the locals have more than thirty names for the different winds that occur on the Lake (in some cases, there are several names for one and the same wind). We will tell you about some of Baikal's winds and you can work out which of them are the most furious and dangerous. See if you can work out the meaning of the different coloured arrows on the map. The southern wind that blows from Kultuk Bay along the length of Baikal is called the Kultuk (or “Nizovik”, which means “lower wind”). The Kultuk usually brings bad weather, with clouds, rain or drizzle lasting for several days, and it is sometimes strong enough to raise waves of up to 6m on the Lake. The Kultuk usually blows in autumn, and it is preceded by a gathering of dark clouds in the south-western part of Baikal. The wind that blows in the opposite direction, from the mouth of the Upper Angara river at the northern end of Baikal, is called the Verkhovik (“upper wind”). The wind is usually gentle and brings sunshine. The water along the shoreline remains calm when the Verkhovik blows, but further from the shore the Lake becomes dark and its surface is covered with white foam. A bright red horizon before sunrise is a sign that the Verkhovik can be expected. A north-eastern wind, the Barguzin, sometimes blows from the Barguzin Valley in the central part of the Lake. It blows evenly and gradually gains force, but is less powerful than other winds on the Lake. The Barguzin brings sunny weather. It usually starts to blow in the morning after sunrise and dies down towards sunset. 37 The most treacherous and blustery wind on Baikal is the Gornyak (“mountain wind”), a storm wind that blows from the west and northwest. It is often preceded by cumulo-nimbus clouds on the Lake's western shore. The Gornyak is most usual in the period from October to November. When the Gornyak blows very strongly, it is called the Sarma (after the name of the river valley, from which it blows). The Sarma reaches speeds above 40 km/s, and it can break the rooves of houses and overturn boats (even motor-launches). The appearance of stratocumulus clouds over the peaks of the Primorsky ridge are a warning that the Sarma is on its way. In the summer the Sarma begins and ends suddenly, but in the autumn it can blow all day long. The wind often rises quickly and unexpectedly, making it particularly dangerous. The Buguldeika is another variant of the Gornyak, which rises in the valley of the river Buguldeika and can blow for days on end. A warm south-east wind, the Shelonnik, sometimes blows onto the Lake. The Shelonnik raises waves, but dies away before it reaches the other side, so that breakers sweep onto the western shore in apparently windless weather. The Shelonnik is most usual in spring, autumn and at the beginning of winter. Does a calm every occur on Lake Baikal? It often happens that several winds blow at the same time and cannot be easily distinguished. On such days the wind direction can change unpredictably to its opposite. Baikal is only free of wind in the middle of the summer. The time of least wind in 24-hour periods is the two or three hours after sunrise and before sunset. A calm that lasts for a whole day is a rare occurrence: local people call it a “Baikal sheen”. In addition to the dominant winds, which we have described, there are light local winds that blow on Baikal almost every day. These are breezes, similar to those which occur on sea coasts: on hot summer days cold air from the sea is drawn into the valleys and lowlands on shore, while at night the breeze is from the land onto the sea, which retains the day's warmth. Calm – we say that the weather is “calm” when there is no wind, or very little wind. Breeze – changes its direction in any 24-hour period: at night it blows towards the sea, and in the daytime towards the coast. 38 Think, Play, Experiment, Create together!

Use a computer to help you Unique properties of Baikal water Young friends! You already know that Baikal holds 20% of the world's fresh water. It is sometimes called 'the planet's well'. Let's dive deep into the waters of Baikal and find out what wonders they contain. Look at this photo. What adjectives would you choose to describe Baikal water? Baikal water is uniquely pure and transparent, particularly in the spring after the ice melts. It then becomes slightly murky as tiny water organisms called plankton multiply and grow. Secret Corners of Baikal’s Little Treasure Chest Water transparency is measured by a special device called a 'Secchi disc', named after Angelo Secchi, an Italian astronomer, who measured the transparency of sea water using the device as early in 1865. The white disc with 30 cm diameter is lowered face-down into the water, using a rod, and the depth at which it becomes invisible is recorded. That depth, expressed in meters, is the measure of water transparency. The table shows the water transparency in various seas and lakes. You can see that water transparency in Baikal is more than 40 meters. Water transparency in seas and lakes (meters) 0 10 20 30 40 50 60 The Sargasso Sea Lake Baikal Lake Issyk Kul The Baltic Sea 50 Lake Ladoga Lake Ilmen The water in Baikal is rich in oxygen, which, as you know, is vital for the survival of all living organisms. The main sources of oxygen are water weed. But the surface layer of Baikal water also receives oxygen from the air, and oxygen is supplied at greater depths thanks to water transfer driven by wind and currents. Baikal water has a unique chemical composition, containing about 40 elements: calcium, oxygen, magnesium, sodium, potassium, silica, sulphur, chloride, nitrogen, iron, phosphorus, iodine, and many others. Baikal water is fresh, containing little salt. It has a soft and pleasant taste, without smell, and is exceptionally safe and healthy. Secret Corners of Lake Baikal Box Over 2 billion liters of bottled water are collected from Lake Baikal each year, so there is no need to visit the Lake in order to appreciate the taste and quality of its water. Water is collected from a point 1007m from the shoreline and 500m below the surface. Why was it necessary to go to such a depth? It was found that water in this zone had a high level of purity. The water is bottled at special centers on the southern shore of Baikal, in the village of Listvyanka and the town of Sludyanka. So transparency, saturation with oxygen and chemical elements, purity, absence of smell, softness and taste quality are the main features of Baikal water. Do you think that the water of Baikal has any colour? Why does the colour of water in Baikal change? The water of Baikal may be light blue, emerald green and even black. The water in the middle of the Lake is dark blue, but the water close to the mouth of the Selenga river can be grayish green, reddish and brownish black. The water colour in Baikal is influenced by the weather: the amount of sunshine that penetrates the depths; whether the sky is cloudy and whether the wind is blowing. In sunny weather during the summer the water turns green and blue, but if the weather is stormy the Lake appears almost black. The temperature of Baikal water Depth (m) Temperature Upper layer + 9-10° С 200 m up to – 5-6° С 900 m up to – 3-4° С 1600 m up to – 3° С Using the table data, draw the layers of water in Baikal, write their temperature, and try to think of their make them the right colour. 51 Baikal waves How are waves made? They are created by the influence of wind, tides, earthquakes, vessels moving on the water, and other external factors. The waves on Baikal can be up to 4m high, depending on the wind speed, duration of its action, and the distance over which the wind drives the waves. Waves on Baikal are caused by the various winds, which blow across the Lake. When the wind blows at a speed of less than 1m per second, the waves that emerge on the still surface of are no more than ripples. If the wind blows at 4–5 m per second the waves grow larger and more visible. 52 Large waves with foaming tops are called breakers. If wind speed reaches 7–8 m white horses appear on the wave crests: these are air bubbles formed when the wave crests roll over. Waves on Baikal are not of long duration. If they are caused by winds such as the Kultuk or Barguzin, the disturbance comes and goes in the course of one day, and if the waves are caused by a local breeze, they last no longer than 2–3 hours after the breeze dies down. Secret Corners of Lake Baikal Box Look carefully at the waves. They seem to come one after the another, moving forward. But this appearance is false. You can prove that by an experiment: drop a float into the water when you are on the Lake shore. Now watch carefully. You will see that the waves seem to move towards the shore, but the float only makes circular movements. This shows that the particles of water, that make the waves, are also moving in circles. 53 Baikal ice Every year Baikal freezes over gradually from north to south. The first to be covered are shallow creeks, and deepwater sections of the Lake freeze last. Baikal remains ice-covered for several months, except in one ice-free zone extending for 15-20 km where the Angara river rises. Average thickness of the ice is 1m, but this varies depending on snow cover: the thicker the snow, the thinner the ice. Frequent storm winds cause uneven snow cover in different parts of the Lake. Ice formation depends on air temperature and weather. When the weather is calm and air temperature is below -20°С as much as 4-5 cm of ice can form in 24 hours. There are many local words to describe the ice in Baikal, depending on where it is and how it forms: “sokui”, “osenets”, “salo”, “shuga”, “shorokh”, “kolobovnik”, “torosi”. 2 What do you think is the difference between ice thickness on opposite shores of Baikal if the ice on the western shoreline is free of snow, but the eastern side has snow cover of 80–100 cm? 1 The photos show different kinds of Baikal ice. Look at them and try to guess which names are used. 54 A thin ice cover that appears on rocks and stones due to water splashes is called “sokui” (1), and it is the first sign that the Lake is about to freeze. More water splashes freeze and form new layers , so the ice becomes thicker and has a wave-like surface structure. Sokui can be seen along the shore, reaching heights of 10m above the water level. As the temperature drops drift ice appears. At first it moves from one place to another across the water, driven by the wind, but it gradually freezes fast and binds the Lake under a thick layer. Floating ice has been given the name “osenets” by the local people (2). It is characterized by an opaque whitish colour and uneven surface. Locals have given the name “salo” (“lard”) (3) to another ice variety, consisting of thin, flat crystals of ice that have not frozen together into a solid ice layer. They appear on the still surface of the water and are a sign that the water temperature has fallen below 0° С. Whether or not salo appears depends on how warm the Lake became during the summer. In shallow parts of the Lake the water cools down earlier than in others parts, so this kind of ice appears there first. At night, in calm weather, the crystals of salo freeze together and develop thin crusts. The crusts are then broken into pieces by currents and waves, forming crumbly whitish pieces of ice, called “shuga” (4). Later, grains of ice called “shorokh” appear in the water (5). The crystals of this ice are either needle-shaped or round. Waves and wind break off the edges of ice masses. Those broken pieces, with a round shape and murky coluor, are called “kolobovnik” (6). Closer to the middle of winter cracks appear in the ice layer of Baikal. The cracks can be as long as 30 km, with width of 2–3 m. The crack formation is accompanied by a noise and rumbling comparable to guns shooting or blasts of thunder. When the temperature rises and the cracks become thinner, the ice is squeezed upwards and creates a “toros” (7), which can be as high as 10–12 m. The ice on Baikal breaks up between April and June. Large pieces of floating ice can still be seen even at the beginning of the summer in the northern part of the Lake. The highest water temperatures, of +26° С, can be reached at the end of the summer, particularly in the Chivyrkuysky Gulf. 3 6 5 4 7 55 The living water filters of Baikal Baikal's water is kept clean by living organisms which are called “biofiltrators”. Let's find out more about them. The Baikal Sponge Baikal sponges are animals in appearance very similar to plants. Their structure is close to that of coral and they live on stony sections of the Lake bottom, and on underwater rocks. They can be found at depths up to 100m. Sponges are very important for Baikal, since even a small organism (5–7 cm across) can filter 10–12 liters of water every 24 hours. The underwater forests formed by sponges are also home to fish larvae and fry, water worms and molluscs. Local residents have found an original application of sponges in housekeeping: their rigid lime skeleton can be used to do the washing-up. There are 19 kinds of Baikal sponges, including 14 endemics (found only in Baikal). The endemic varieties include Baikalospongia, Lyubomirskaya, Svarchevskaya and Rezinkovaya. The names are unusual, but try to remember them. Endemics (from the Greek word meaning "local") are animals and plants, which are only found in specific and limited territories. The most widespread sponge is the Lyubomirskaya. These sponges live in places where light penetrates and they stand out by their emerald-green colouring, caused by the mono-cellular green water weed, which covers the body of the sponge. The deeper the water, the lighter the sponge. The Lyubomirskaya sponge may be branched or flat and can grow as high as 1m. It grows very slowly (by 0.5 to 1 cm per year on average). Branched sponges form underwater forests at depths of 5–20m. Its feeding mechanism defines the sponge as a filtration organism or biological filter. All sponges are characterized by an unusually acrid and unpleasant smell. Sponges are also important for the circulation of chemical substances in the Lake. The sponge uses silica compounds that are dissolved in the water to create its own skeleton. 56 Venus Amphipods and Bormashi Amphipods are a type of crustacean living in Lake Baikal. Their Russian name (“bokoplavy” = “side swimmers”) reflects the way they move through the water. Amphipods are the commonest types of Baikal fauna and can be found all around the Lake. They can burrow into sand and silt, and also move through open water. Amphipods have a special place Baikal's food chain, being eaten by various fish (omul, Baikal oilfish, grayling, bullheads) and even by seals. These crustaceans are omnivorous, eating plants and small animals. Some of them feed on dead organisms, helping to keep the Lake water clean. Venus amphipod The largest kind of amphipod is the Venus amphipod. It lives in deep water and can grow to 6-9 cm, which is unusually large for these creatures. Smaller amphipods (from 3-6 up to 14-30 mm) live permanently in open water and are called “yur” by the locals. At night billions of them rise up to the water surface, retreating back downwards to depths of more than 200m when the dawn comes. Amphipods move at an estimated speed of 1m per minute, tracing spiral paths in the water. Small amphipod types are known as “bormashi” (“amphipod shrimps”), and they live along the shoreline of Baikal as well as in rivers and small lakes. They vary in size and colouring and are the main source of food for fish, particularly the Baikal omul, so that fishermen often use them for bait and to attract the fish. They are also used for ice fishing. Secret Corners of Lake Baikal Box “Amphipod” is a term from Greek meaning “with different legs”. The 13 pairs of extremities on an amphipod carry out different jobs: some are used to capture food, others for walking, others for swimming, while others operate as wheels, supporting the body and guiding it in a certain direction. The colouring of amphipods is diverse, but they are usually brightly coloured (orange, red, violet, crimson, and green). Deep-water amphipods develop long antennae, which they use to orient themselves in space, detect smells, and perceive the slightest movements of the water. 57 The Baikal epischurа The Baikal epischurа is a related to the amphipods. For the greater part of the year most of them are found in the top layer of water, where there may be between 3000 and 45,000 of them per cubic meter. In the cold season, epischura account for more than 90% of all plankton creatures. The Baikal epischurа is exceptionally small (no larger than a semolina grain). But it is the most hardworking animal in Baikal. It is hard to imagine, but the creature's mouth allows it to eat tiny pieces of water weed and bacteria as it filters water and returns it pure into the Lake through its gills. During one year the armada of epischurаs can clean the entire top layer of the Lake to a depth of 50 m three times over. The creature therefore deserves it name – “the miracle of Baikal”. The epischurа is particularly sensitive to water temperature, being unable to live at temperatures above 15° C. It consumes a great amount of Baikal's water weed and it is an important source of food for Baikal oilfish, omul, bullheads and other fishes. Dear children, you know that Baikal is the purest natural storehouse of fresh drinking water on Earth. Now you also know that the exceptional purity and other properties of the Lake water are the result of action by its animals and flora. In the next part of this Book, you will learn about the species that live above the water and under the water of Baikal. Secret Corners of Lake Baikal Box Plankton are microorganisms that live deep underwater. The term was first used by a German scientist, Victor Genzen, at the end of the 19th century. 58 Think, Play, Experiment, Create together! Check what you have learnt! What do you remember about the miraculous qualities of Baikal water? 1. Why is Baikal water called unique? 2. How can the transparency of water be measured? 3. What determines the colour of Baikal water? 4. What waves can be seen on Baikal? 5. What crustacean is considered to be a miracle of Baikal and why? 6. Tell the class about a sponge, which bears a name of a well-known researcher of Baikal's fauna (see Part 5 of Lake Baikal Box) 7. See if you can find the name of the ice, described below: – it is the first sign of Baikal's cooling below 0оС; – it consists of thin flat crystals of ice, which have not frozen together in a continuous crust. What is living water? 1. Do you remember why the waters of Baikal are called “living waters”? Dead water Living water 2. You can see frozen crystals of water in the picture, as shown by a Japanese scientist Masaru Emoto. 3. What do you think is the difference between living water and dead water? 4. Think of Russian fairy tales. What do they say about living water and dead water? 5. What is your understanding of the Russian saying “Don't spit in a well”? 6. What do you know about holy water? Can it be called “living”? 59 I am a researcher! My observations. How much water do I need a day? Conduct your own investigation: how much water do you use every day and what do you use it for. Answer the questions: 1. What for does a man need water? 2. Think over and answer, where and how much a man uses water. Find out how much is used by one person in one day in a house with running water, drains, bathrooms and centralized hot water supply. Then find out what the norm is for houses that do not have these facilities. Do we really use that much water? Washing-up usually requires 10-20 liters of water a day, we use 2-50 liters for washing our hands, and a bath takes 150-180 liters, while a shower needs only 30-50 liters. So daily water use per person, including a shower but not a bath, will be under 200 liters. Based on that, work out how much water your family uses on average. Think of rules for saving water in your household. 60 Check what you have learnt! Baikal's “cleaners” Read the text and answer the questions. If there are any words you don't now, find them in a dictionary. Answer the questions: 1. Who do we call the guardians of purity and transparency of Baikal's water? 2. Why is the epischura called the “cleaner” of Baikal? The main “cleaners” after purity and transparency of water are amphipods. There are more than 350 kinds, that is 1/3 of all known amphipods in Baikal. About 90% of all amphipods make two kinds: epischura and copepods. They are met only in Baikal and they keep the purity of the water together with Baikal’s ecosystem originality well. Epichura can be easily callled “a yard-keeper” of Baikal. Its length is about 1,5 mm, but under every square meter of the water more than 3 mln of epichura can be met. Every epichura clears 15 cubic meters of water. The cleaner the water, the more amphipods. Epichura appeared in Baikal about 20 mln years ago, and all generation ate only natural compouds. And if epichura dies, then Baikal will loose its unique purity. Copepod – is a colourless and hardly observable amphipod, but it’s more solid – up to 3 cm. It works as a “night man”. Everything that stops moving, or dies or drowns is its food. Main “cleaners” after Baikal’s water purity 3. What other crustaceans living in Lake Baikal do you know? Find out some interesting facts about underwater inhabitants and “cleaners” of lakes and seas in other books. 61 Check what you have learnt! 1. How are the inspectors of cleanliness and transparency of water of Baikal called? 2. Why is the epishura called the “cleaners” of Baikal? 3. Who are freshwater shrimps and why are they so unique? What crustaceans are shown in the photos? Write down their names. 62 Let's be creative! Draw from memory one of Baikal's cleaners or guardians. 63 Let's do some experiments! I. Experiments with Baikal water Experiment 1. Does an egg sink in water? You will need: – a raw egg; – water; – a glass; – a few tablespoons of salt. Do the following: 1. Put the raw egg in a glass with pure water. 2. What do you observe? Write it down 3. Take the egg out of the glass and dissolve some spoons of salt in the water. 4. Put the egg in the glass with salty water. 5. What do you observe? Write it down How do you explain the result? Try the same experiment with other objects: take a sheet of paper (smooth and crumpled), a piece of clay (make a ball from it and then a boat). How do you explain the results? Let's ask a scientist: An egg is more dense than fresh water, but less dense than salty water. So the egg sinks in fresh and floats in salty water. The saltier the water, the less it sinks. In the Dead Sea in Israel the water is so salty that a person can lie motionless on its surface without sinking. 64 Experiment 2. Construct a density pyramid You will need: – A tall, narrow glass vessel; – 1/4 glasses (65 ml) of corn syrup or honey; – food dye of any colour; – 1/4 glass of Baikal water; – 1/4 glass of vegetable oil; – 1/4 glass of medical spirit; – various small objects, such as a cork, a grape, a nut, a slice of dry spaghetti, a ping-pong ball, a cherry tomato , a small rubber toy, a metal screw. Do as follows: 1. Pour the honey into the vessel so that it occupies 1/4 of its volume. * Remember that any liquid should be poured down the wall of the vessel. * When pouring a new liquid, pour it very carefully so that it does not to mix with the liquids already in the vessel. 2. Dissolve drops of the food dye in water then pour it into the vessel containing the honey until it is half-full. 3. Slowly pour in the same quantity of vegetable oil. 4. Pour the spirit into the vessel. 5. Carefully put the small objects into the vessel one by one. 6. What is the position of the objects in the vessel? 7. How do you explain this? 8. Draw how the liquids and the objects are distributed in the vessel. 9. Think why the honey has taken the lowest position in the vessel. 10. Write down your observations. Draw your own density pyramid. rubber ball tomato spirit vegetable oil macaroni water screw honey Let's ask a scientist: This experiment is based on the ability of various substances to sink or float depending on their density. Substances with lower density float on the surface of substances with higher density. 65 Experiment 3. Why does a stopper fly out of a bottle? You will need: – a glass bottle; – Baikal water; – a cork bottle stopper; – 3 tablespoonfuls of lemon juice; – coloured paper; – 1teaspoon of baking soda; – PVA glue; – a paper napkin. Prepare for the experiment: 1. Cut out a rectangular shape from the coloured paper (as in the picture №1). 2. Glue strips of paper to both sides of the cork so that it has the appearance of a rocket (look at picture №2). 3. Measure the stopper in the bottle. The stopper should enter the neck of the bottle without being forced. 1 3 2 Do as follows: 1. Pour some water into the bottle and mix it with lemon juice. 2. Wrap baking soda in a piece of the napkin, and bind it with threads (look at picture №3). 3. Put the soda packet into the bottle and seal it with the stopper-rocket, but not too tightly. 1 the bottle on the table and 2 retreat to a safe distance.3Don't put it under a ceiling 4. Put light! 5. The “rocket” will fly upwards with a loud pop. 1 2 1 3 2 3 Let’s ask a scientist: Lemon juice is acid. When it mixes with with soda carbon gas is formed. The build-up of gas in the bottle causes the stopper to fly out. 66 Experiment 4. If you want to make invisible ink, here's how! You will need: – a lemon; – a match or a toothpick; – cotton wool; – a cup of water. – a sheet of paper; Do as follows: 1. Squeeze the lemon juice into a cup. 2. Add the same quantity of water. This is your invisible ink. 3. Dip the match or a toothpick with cotton wool on the end into the lemon juice and water solution. 4. Write something on a paper with the match. Leave the paper overnight so that the ink dries. 5. Heat the paper over a table lamp. The written words, which had been invisible, will start to appear. Let’s ask a scientist: Sugar, acids and other chemical substances in the lemon juice darken when they are warmed, but paper does not. So your secret message written with lemon juice will show up on the white sheet. 67 Experiment 5. How does yeast "behave" in water? You will need: – sugar; – a pack of dry yeast; – warm water; – a balloon; – a one-liter plastic bottle; – a funnel; – a tablespoon. yeast Do as follows: 1. Insert the funnel into the one-liter plastic bottle. 2. Pour the yeast, the tablespoon of sugar and a mug of warm water through the funnel. 3. Fit the balloon over the bottle. 4. Make sure that the balloon adheres tightly to the bottle. 5. Shake the bottle for 30 seconds. 6. Leave the bottle at rest for 15-30 minutes. 7. Put your ear to the bottle. What can you hear? Why is there a hissing sound in the bottle? How do you explain it? Let’s ask a scientist: Yeast is a living organism and it eats sugar. When poured into a sugar solution the yeast starts to produce carbon gas and to multiply. Pressure of the gas in the bottle inflates the balloon. The foam which you see on the liquid surface consists of tiny bubbles of carbon gas produced by the yeast as its uses up the sugar. The hissing sound you hear when you put your ear to the bottle is the generation of carbon gas as the yeast “eats” the sugar. 68 II. Monitoring Baikal ice Let's remember the properties of Baikal water. We can carry out a few experiments. Experiment 1. At what temperature does water freeze? You will need: – two thin plastic glasses; – boiled water; – water that has not been boiled. Prepare for the experiment: Carefully wash the glasses. Do not wipe them dry but let them dry naturally, turn them upside down so they do not accumulate dust. Do as follows: 1. Wait until the air temperature is equal to 0°С. 2. Put the glasses with boiled and unboiled water outside the window. 3. Cover the glasses with pieces of glass to prevent dust entering. 4. Make sure that the glasses are not exposed to direct rays of the sun. 5. Check the content of the glasses after school. 6. Draw your conclusions and write them down. Unboiled water Boiled water 7. Do the same experiment when the air temperature is below 0°С. 8. What are your conclusions? Write down: Unboiled water freezes at a temperature of Boiled water freezes at a temperature of 9. Think why unboiled water freezes first? 10. What does this experiment show? Write down the results of the experiment. 69 Experiment 2. Can you make coloured ice? You will need: – a plastic glass; – water; – colour gouache. Do as follows: 1. Pour some water into the glass. 2. Add a little gouache and mix it. What do you see? Draw it. 3. Wrap some cloth around the glass. 4. Put it outside on the snow. 5. Do you have coloured ice? 6. What have you in fact got? Draw the answer. BEFORE freezing AFTER freezing 7. Write down what you see. 8. Complete the sentences: At the place where the water started freezing, the ice The top part of the ice ___________________________________________________________. Choose the right answer: – intensity of colouring of the top part is stronger than that of the initial solution; – weaker than the initial solution; – similar to the initial solution. 70 Experiment 3. Water, ice, snow Cool a glass of boiled water to 0°С. Then throw a small lump of ice or snow into the glass. What do you observe? Write down what you see. Experiment 4. Why does ice float? Take a bowl with water. Put a piece of ice from the refrigerator into the bowl. What do you see? Think why the ice floats? Write down the answer. Explain why rivers and lakes do not freeze right to the bottom? Experiment 5. Gradual freezing Fill one third of a thin plastic glass with water and put it in a cold place. When the water in the glass freezes, add a little more water. Incline the glass at a slight angle, being careful not to spill the water, and then freeze it. Do this experiment changing the position (shape) of the glass and the quantity of water added. Describe the results. So what are the properties of ice? Write down your conclusions. 71 Let's do some experiments! Laboratory work. Properties of Baikal water. 1. Pour Baikal water into one flask, tap water into another flask, and water from a local source into a third flask. Number the flasks. 2. Compare the properties of the liquids for transparency, colour, presence of suspensions and smell. 3. Write down the data in the table. Properties of water Flask number Transparency Colour Smell Presence of suspensions a) Transparency of the water. Take a glass with a wide bottom, pour water of each type into it by turn (each time 100 ml), hold it over a page of printed text at a height of 10 cm and try to read the text. Characterize the transparency of each water type. b) Colour of the water This analysis should show the colour of the water: transparent, murky, with a specific colour shade. The colour can be defined by means of a clean sheet of paper. In daylight the sheet should be put behind the flask, before looking carefully at the water colour. c) Smell of the water (whether it has or does not have a smell) d) Presence of suspended particles. Presence or absence of suspended particles, flakes, etc. in the water can be established by observing whether or not a deposit is formed. The analysis is in two stages: – Shake the flasks, compare them and see whether any flakes, particles and other deposits are visible, floating in the water; – Filter the water and look at the filters to see whether there are any significant deposits in them. 4. Compare the results and draw conclusions. 72 Let's be creative! Creative work 1. What are ice crystals like? Look at the picture. This is a crystal lattice of ice. The black balls are distributed so that each of them has four “neighbours”. The task. Make a model of a crystal lattice of ice like that in the picture using salty dough or coloured plasticine. Connect the crystal balls with a toothpick. You can paint a model made from salty dough using gouache. You should keep the crystal lattice of ice made from plasticine away from any source of heat. Creative work 2. How can a water drop get into a house? Imagine that you are drop of water. Think and write how you would get into a house. 73 I am a researcher! A pure river Plan a route for an imaginary small river from your house to Lake Baikal. Do the work in groups. Try to follow particular rules within your group. Make a small river route. Describe who and what it will meet on its way to Baikal. Try to predict the consequences of pollution. You might begin like in: “More than 10 small rivers flow down from the east slopes of Hamar-Daban and give rise to the river Gilbira. First it flows through cedar and fir wood, then through mixed wood. The Gilbira flows from north to south and merges with a small river, the Orongoy, which flows into the Selenga as its carries its water to Baikal. The Gilbira is part of the Baikal's river basin and it has an impact on the state of Baikal's ecosystem, because the Lake's water depends on the rivers flowing into it, and 50% of its water comes from the Selenga river. The small river becomes polluted...” Think how your story ends. 74 Let's be creative! Draw a snowflake Look, how beautiful snowflakes are! They are very different! You can make sure in this yourself looking at them on your palm in winter. Try to remember thier shapes. Firstly, fulfill this exercise: draw the snowflakes according to the sheme. And now think over and draw you own snowflake. Put together a sheet of paper a few times, and then with the help of scissors you can cut out an amazingly beautiful snowflake. To cut a snowflake out put together a sheet of paper according to this scheme. 75 “The Adventures of a Water Drop.” name Hi! My r Drop. is Wate oating high ts I love fllouds!

Probably it will be a story about how Water Drop helps a man, or how Water Drop tells about water saving. You can also tell how Water Drop found our house or how she flew to another planet a met aliens. Maybe you will get a glimpse into the future, and we will know what is awaiting for Water Drop in a hundred years .... New adventures of Water Drop are in your hands! We want your story to be very interesting and teaching. Mind it! Retell your fantastic plot in pictures-comics. Here are some pieces of advice which will help you to make up comics: 1. Define main moments of Water Drop's adventures: – where does the action take place; – whom did Water Drop meet on her way; – what trials do they have to cope with; – what do the comics' characters talk about; – what does the story end with; – what did Water Drop learn to do or what can she teach a reader to? 2. Think over a new image of Water Drop and other characters of your comics: – what do they look like; – what traits of character do they they have; – transfer their mood: joy, surprise, grief, etc. Changing form and shape of eyebrows, eyes, mouth you can add the characters different expression (laugh, sadness, etc.). Look, how it can be done. 78 3. Comics, as you know is a row of pictures. They are quite different, and they can be placed in different ways. A sheet of paper takes up different positions either vertical or horizontal. You can paint pictures of the same size and form, but it is not necessary. Some artists surround a picture with a wavy or a dotted line. But usually it is a black straight line. 4. In order to “hear” the comics' characters, you need to draw clouds, those which fly out of their mouth when they speak. Professional comics' painters call them “balloons” or “bubbles”. They can be of different shape. In an oval or a rectangular bubble they right what a character syas in his usual voice. A short tail is connected with the character's mouth. The character's thoughts are written in a bubble which really reminds a cloud, and then little circles are connected with the character's head. If a character is crying out, his words are written in a shape with sharp corners. Such “stars” painters draw when an explosion takes place. 5. If you make up comics together with your friends, then you can draw up its plots on separate cards and them connect them in a united series. 6. To create comics, use abilities of your computer. It is much better to make up comics about Little Drop together with your friends. When you draw them in the pictures and then join all sheets of paper, you will get a comics-magazine about Droplet’s adventures. The main rule is: “Making up easily, drawing nicely, playing merrily!” 79 PART Above Water and Under Water As soon as Mother left the house, at any weather Seal pup got into Baikal’s water, And on the ice-floe – what can we expect from the fidget – He secretly went to walk barefooted. He swam in Mom’s hat with large fields, And he didn’t listen to his father – he made friends with omuls. Once a naughty omul fell into a net, But our sea-pup helped him to get out of it.

Have you ever been on a river, lake or sea? Do you remember what birds live by the water? And do you know what birds you can meet on the shores of Lake Baikal? Dear friends, watch the birds that you see every day. Photograph or draw them and make a story about one of the birds based on your observations. Ornithologists divide all of Baikal's birds into water and waterside birds, shore birds and forest birds. Ornithologists are biologists who study birds. If you are lucky enough to take a boat across Lake Baikal, you are sure to come across large flocks of ducks. A great numbers of gulls perch on the rocky islands of the Lake, and when you are far from land you will see cormorants. Bird thrive in the delta of the Selenga river and in shallow bays. Whooper swans are occasionally to be found on the shores of Lake Baikal, and on the banks of rivers around the Lake you might see a gray heron, a dipper, a wagtail and several species of curlew. In total there are 392 species of birds inhabiting the Lake region, of which 200 live on the shores of Lake Baikal itself. How can we find our way in all this diversity? How can we recognize the bird that flies past us as one we already know or spot a bird of a rare species? This is what we will discuss in the third part of our Book. 84 Gulls on Lake Baikal You know who this is, of course – it is the Yellowlegged Gull, one of the largest gulls on Lake Baikal, and one that stands out from the others: you can recognize it by its white plumage, gray back and the black tips on its wings. Its beak and legs are yellow. Its cry sounds like a loud laughing, which explains the Russian name “the cackler” (“khokhotunya”). Gulls find their food in water and rest on water. Yellow-legged Gulls are good swimmers, but they don't dive. They can use air streams to hover in the air for long periods. They move easily along the ground and are good runners. They live in large colonies. Gulls are the commonest water birds. They build their nests on islands, dry sandy hills along creeks, and on the shores of lakes where there is good grass cover. The nest usually has 2-3 eggs, which are brownish green or yellowish olive with dark spots. Secret Corners of Lake Baikal Box Gulls come to Lake Baikal in mid-April, when the lake is still covered with ice, and stay until October. They eat fish, which they spot from the air, as well as large insects, mollusks, worms, and sometimes the eggs or nestlings of other bird species. Gulls are often called “water cleaners" because they eat carrion, food scraps, and weak and sick fish. A close relative to gulls is the Common Tern. It's a bird of starling-size. One can know her due to its gaunt body, long and narrow beak, and tail of fork-shape. Its back and belly are warm grey; there is a black hat on the head; its beak is red and black, its legs are red. While hunting the bird hangs in the mid-air above the water flapping, and then it it falls down the water like a stone. Look at the pictures of gulls. See what features set them apart from other birds. How many years does the Yellow-legged Gull live? Where does it hibernate? Find the answers to these questions and add the new information to Lake Baikal Box. 85 Are all waterfowl birds the same? Of course not. They differ in size, color of plumage, how they nest and how they feed. There are believed to be several dozen different species of duck in Buryatia, and about 20 of them live on the shores of Lake Baikal. Recognizing a waterfowl bird is quite easy, because they all have flat beaks and webbed feet, which help them to swim so well. They don't like walking on land. Nearly all of them fly away to warmer climes for the winter – they are migratory birds. But the different species of waterfowl birds have some unusual features. This, for example, is a tufted duck. There are various Russian names for it: a “grass-eater”, a “white-side”, and several others . It finds its food in clean water and can dive to a depth of 4-5m. Its colouring sets it apart from other ducks: its belly and sides are white, the breast is black, it has a short tail and a tuft on its black head. The tufted duck is often to be seen at the northern end of Baikal in the valleys of large rivers such as the Barguzin, the Kichera, the Upper Angara and the Svyatoy Nos peninsula. It is also to be seen in the Selenga delta and on the small lakes of Baikal's terrace. The birds arrive in April and fly away to winter grounds in September or October. We have already seen that some birds stay for the winter, which they spend on the ice-free waters at the source of the Angara river, but such wintering is often an ordeal and many of the ducks perish before the spring. 86 And do you know, children, which bird loses its plumage in winter? It is the great crested grebe (“chomga”), also known in Russian as the “bolshaya poganka”. The great crested grebe can be recognized from its peculiar appearance: it has a thin neck, long straight beak, a brownish-red back, and its neck and head are white. In spring, two dark clusters of feathers grow on its head, having the appearance of ears or horns, and a red collar grows round the neck. All of this extra plumage is lost in winter. The great crested grebe lives in the Selenga delta, the Chivyrkuysky Gulf and the Upper Angara. The birds arrive in April or the beginning of May, and fly away in September. Young couples build new nests in the nesting areas, but old couples return to their usual spots and are highly protective of their own territory. The great crested grebe winters in Europe, on the Caspian and Black seas. A great crested grebe, which had been ringed on the shore of Lake Baikal, was once found in Germany. The great crested grebe is a skilful swimmer and diver – it can dive to a depth of 7m and stay underwater for more than a minute, and can also swim underwater at high speed (60m in 30 seconds). It feeds mainly on fish. While building their nest the birds fetch pieces of water weed from the bottom of lakes and rivers, and give them to each other as gifts. The great crested grebe builds its nest of reeds or cane on the surface of the water, creating a floating island. Secret Corners of Lake Baikal Box The chicks, covered in down, hatch about 25 days after mating and are almost immediately placed on the back of an adult bird. They stay out of the water for nearly two weeks, riding on the back of one or other of their parents. The great crested grebe has one other interesting feature: it will allow a person to come close to it, but it cannot be caught because it will dive deep into the water at the last moment. The grebe was hunted close to extinction in many European countries in the 19th century, because its extravagant plumage was popular as a decoration for women's clothing. Populations are now recovering thanks to protective measures in European and Asian countries. 87 What is the difference between a teal-whistler (Green-winged Teal) and a teal-cracker (“Garganey”)? Teal-whistler Teal-cracker Compare the ducks in the pictures. What are their similarities and differences? You will learn the exact answers below. Green-winged Teal is among the most numerous species on Baikal. It is the smallest duck on the Lake and flies in small groups. It arrives in the southern part of Baikal in mid-April and in the northern part of the Lake in May, when the rivers thaw out. The Eurasian teal nests on water where there are willow thickets or large old trees. These ducks are very energetic – they like to fly over shallow water, making steep curves and turns. Their distinctive call explains why they are called “whistlers”: the males, particularly, produce a low, abrupt and loud whistling sound, while the females produce a shrill, highpitched quack. The sounds make an interesting mixture when the birds are calling each other. The Teal cracker (Garganey) is a little bigger than a Green-winged Teal, it has a brown head and a white stripe from the eye to the nape of its neck, and a light-grey pattern on its sides. It arrives on Baikal at the same time as the Greenwinged Teal, and settles in the Selenga delta, the Chivyrkuysky Gulf, the Upper Angara, and on the banks of small rivers. Unlike the Greenwinged Teal the teal cracker does not make its nest on water surrounded by trees. Instead, the female makes a hole in dry ground, lines it with dry grass, then, after laying eggs, the nest is completed and covered with belly down. The crackly voice of the teal cracker, much heard both on the water and in the air, comes from the male, who is always found together with his mate. The Russian name, “treskunok” (from the word for “crack”), reflects the distinctive sound of the bird's call. 88 All ducks quack, but in Russian only one is called the “quacker” (“kryakva”). This is the Mallard, which is the most common of all the ducks found in Buryatia. It can be recognize from its voice and appearance: the head and neck of the male is green, the breast is brownish-fulvous, and the back and belly are grey with spots. The female is brown and the spots on its grey belly have a darker hue. Both male and female have a mirror-like blue-violet spot on their wings. Secret Corners of Lake Baikal Box Mallards arrive on Baikal in early to mid-April, and depart en masse at the end of September or start of October. Flocks of several hundred birds can be seen during the migration periods. In some years small flocks even remain to winter in ice-holes. The mallard lives on the banks of shallow water, feeding on water plants and small insects. It nests in thick grass and in bushes, and, very occasionally, uses the tree nests of magpies. Mallards lay 7-10 white eggs with a greenish hue. Task: Try drawing or making a wild duck from plasticine based on the description in our book. The photograph of the bird will be helpful too. The Ruddy shelduck, or red duck, is the most common and well-recognized bird in Buryatia. The ruddy shelduck is a land duck, which nests in the fissures and hollows of steep rocky mountain slopes, in stone ravines, in the burrows of large animals and in tree hollows. In September they migrate to warmer climes, but return to Baikal early, at the end of March or start of April. The ruddy shelduck is a large dark-red bird; its head is white, there is a black stripe on the neck, and it has black feathers with a white “mirror” spot on the wings. The male has a dark stripe on its neck. Secret Corners of Lake Baikal Box It is interesting that the female ruddy shelduck makes sure that its nest is no further than 3 kilometers from water, so that the ducklings can reach the water by themselves. 89 How can you recognize a cormorant? The adult cormorant has black plumage with a metallic greenishviolet shine. There is a black tuft on the head, a yellow mark from the beak along the head, and a greenish-brown ring around the eyes. The cormorant has webbed black feet, a long neck, and a curved brownishblack beak. In terms of size the cormorant is comparable with a goose. It weighs about three kilograms. There are many nesting species for cormorants on Baikal, and three islands in the Chivyrkuysky Gulf are even named after the bird: Cormorant Island and two outcrops, both of which are called “Cormorant Stone”. Secret Corners of Lake Baikal Box Cormorants feed only on fish and they hunt in groups. Their hunts are a noisy affair: they clap their wings together, cry, dive, and splash in the water, as they hurry to keep pace with shoals of fish. When the hunt is over cormorants sit on the shore with their wings spread, drying their plumage. It is interesting that people in south-eastern Asian countries, where cormorants fly for the winter, use the birds as “living fishing rods”: fishermen make the cormorants dive for fish and then take the fish for themselves. In the second half of the 19th century there were thousands of cormorants in the Selenga delta and the Barguzin river. Fishermen were worried about the impact on their livelihoods and began to hunt the cormorants, which were almost extinct by the mid-20th century (they were even registered in the Red Book of Buryatia). Nowadays ornithologists report that flocks of cormorants are increasing, and they have been removed from the Red Book. Choose one picture of the bird which particularly strikes you. Use it to make up a story with the help of additional resources. Pintail Shoveler Avocet Wigeon 90 Shore Birds What birds do you know that inhabit the shores of Baikal? Ornithologists call them “waterside birds” because they cannot live for more than a day away from water. They get their food from water, and build nests on the shore. There is a Russian proverb, “Every sandpiper praises its own bog” (the meaning is close to “there is no place like home”). But the sandpipers in Baikal are not praising a bog, but the most wonderful lake in the world, on the shores of which they rest and feed on their journey from the south to the far northern tundra. Sandpipers inhabit shallow waters close to the shore, where they spend the day (and sometimes part of the night) running along the water's edge, gathering insects, larvae, mollusks and other food. There are several species of sandpipers, of which the little stint, the common sandpiper and the Eurasian oystercatcher can all be found on Baikal. Their names give us an idea of their sizes, and they also differ in colour: the little stint is rusty-red with brown spots, changing to grayish-brown in winter; the common sandpiper is white-black with a distinctive white spot under the eye; and the Eurasian oystercatcher is grayish-brown. All of the sandpipers have a long, thin beak. The Common Sandpiper can be frequently met on the shores of Baikal and nearby waters. Its call sounds to Russian ears like “Perevezi! Perevezi!” (“Carry me across! Carry me across!”), whence the Russian name for the bird – the “carrier”. Local people interpret the stooping gesture of the bird when its hunts for food along the shore as a respectful bow to Father-Baikal, to whose shores it returns every spring from warmer southern climes. The Little stint and the Eurasian Oystercatcher are rare transit birds, which use Baikal as a stop-over on their journey from wintering places, but do not nest on the Lake. Their Russian names (“sparrow sandpiper” and “magpie sandpiper”) reflect their similarity to these other birds. The Common Snipe – is not a large bird with a long straight and pointed beak. It is widely spread in Europe and northern parts of Asia, also it can be met in the southern part of Baikal. The snipe is good not only at flying, but it can run well even in the grass. It is not easy to see it: it is a very reticent bird. In its free time at noon, it stands hiding behind hummocks and drowing its head into its shoulders. It flies up quacking, and it flies as if it waddles. Besides, the snipe-cock cries out its “taku-taku” or “tyok” on the land, on stumps, on trees. To Baikal snipes come in May. Their autumn flight lasts up to October, sometimes the birds winter on the Baikal's shores not far from non-freezing streams. The Asian Dowitcher – is a bird of dove-size. It has a motley back and wings, its belly is rusty-red, and the tail is striped. The bird has long legs and a long beak. It can be met on Baikal, on lake Big Yeravnoye, on lake Orongoy, on the lakes not far from the town of Kyakhta. In the valley of the Selenga river more than 300 couples of asian dowitcher nest starting from May. They build their nests in moist places putting dry leaves, stalks and grass into a hole. Usually there are 2 eggs in the laying, the parents brood them in turn. It's a rare bird; it isn't studied much. It's registered in the Red Book. They winter in India and Birma, on their way there they stop in China and Japan. 91 Grey heron What bird can stand still in one place for hours, sometimes on one leg, with the other leg tucked under its body? Of course, it is the grey heron, a large bird, weighing up to two kilograms and easily distinguishable from other herons. Its back is grey, the belly is white, and it has feathered wings, a stripe above the eye, a black tuft and a black stripe on the neck. The head is narrow with a long, straight, yellowish beak, squeezed in at the sides. The legs are long and of a yellowish colour. The grey heron has large, wide wings and a short tail. It flies smoothly, at a gentle pace, with slow flaps of its wings. In flight the heron produces a distinctive, instantly recognizable cry: loud and sharp, as if it was shouting “kryank!”. Secret Corners of Lake Baikal Box It is very interesting to watch a heron. When hunting for food, herons stand still for long periods in shallow water or near the hole of a vole or of a gopher, waiting for their prey. If something bothers a heron it stretches its neck, but otherwise remains motionless. However, it can fly away instantly if it needs to. Herons sometimes walk slowly and silently through water, with their head down, looking for prey in the water. The strike is quick and sudden, seizing the fish or other small animal in the herons beak. Herons nest in large colonies on tall pines and there may be several nests on one tree. The male gathers building materials, while the female stays most of the time in the nest, putting the twigs into place. Grey Herons lay eggs once a year or, very rarely, twice. Both parents sit on the eggs. Newly hatched nestlings are covered with grayish down and their plumage appears on the seventh day. Both parents feed and nurse the nestlings, and one or other adult bird remains in the nest at all times protecting the young from sun and rain with their wings. Nestlings knock on the parent's beak when they are hungry and the adult bird eructates food directly into the nestling's beak. Young herons start to fly when they are about 55 days old. 92 The Wagtail and Dipper The Wagtail is another shorebird, like the sandpiper and heron. The white wagtail is found on Lake Baikal and has a distinctive appearance and plumage, which make is easy to recognize. You may well have seen this nimble bird. The wagtail has a long tail, small head, and its colouring is grey, white and black. The birds runs quickly along the shore looking for bugs, small crayfish, young fishes, and other types of food. Wagtails migrate to the banks of rivers and rivulets near Baikal at the beginning of April and leave for warmer climes (Vietnam, Thailand) in the second half of September. Wagtail What you see here is a Dipper – a nonmigratory bird that nests in Buryatia. It lives on the banks of fast-flowing rivers and streams that carry their waters to Baikal. In winter the dipper moves to ice-free streams and springs. The dipper is sometimes called a “water-sparrow” because it can easily run underwater. It feds feeds on water invertebrates but sometimes also catches young fish. Dipper 93 It has thick, dark-brown plumage, which is water resistant. Dippers build their nests on stones and in rock fissures. The nests usually contain 4–6 white eggs, and the bird will often bring a whole fish, which it has caught, into the nest. Trace on the map the route taken by birds when they migrate from Baikal to their wintering grounds. Try to calculate how many kilometers birds have to cover in one direction. Scale: 1 : 20000000 (1 cm : 200 km) Dear friends, you now know a lot about the various species of birds, which live by Lake Baikal. You can learn about other bird species – forest birds – by reading the chapter about protected natural areas around Baikal. 94 Fish of Baikal Baikal's water is fresh, clean and clear. What kinds of fish live in Baikal's water, and which are them are only to be found in Baikal? Ichthyologists subdivide Baikal fish into two main species: Soroviye (because they live in Baikal's bays and shallow waters, which are usually called 'sor') and Baikal fish, which live in the open waters of the Lake. The Soroviye include the Baikal omul, the whitefish, umber, sturgeon, roach, bream, perch, pike and burbot. Ichthyologists are biologists who study fish and marine animals. Best-Known Fish of Baikal Baikal's best-known fish is Baikal omul. Nearly every Russian thinks immediately of the “omul barrel” from the popular song “Glorious Sea – Holy Baikal!” (even if he or she has never been to Baikal and has never eaten omul). But what else do we know about the omul? This is a fish that likes to travel. The omul is found in Baikal and the basin of the Arctic Ocean. Though many ichthyologists consider the omul to be endemic to Baikal, there is a closely related fish, the Penzhinskiy omul, which is found in the Penzhinskiy Lakes in the north of Russia. The omul feeds mainly on small crustaceans living in the Lake water, invertebrates at the Lake bottom and the young of goby fish. The omul enters rivers to spawn from the end of August or beginning of September up to the end of November. The time of spawning depends on water temperature (the omul will not spawn until the water is cold enough). It is also of interest that the omul will only spawn upstream in rivers. “Omul” in Latin means “wandering white-fish”. Secret Corners of Lake Baikal Box A real riddle is how the omul got into Baikal in glacial period or postglacial period from the rivers flowing into the Arctic Ocean. Does it mean that the omul might be a mammoth’s contemporary or, for instance, a herbivorous dinosaur of the Age of Reptiles? One bone of such a dinosaur was found not far from Gusinoye Lake. Now it is kept in Baikal museum of the settlement of Listvyanka. 95 One spawning shoal of omul may consist of between 1.5 million and 6 million fish. At this time the water in Baikal's rivers seems to seethe and glitter from the huge number of fish that it contains. Omul release spawn on sand-and-pebble areas of the river bottom. Fertilized eggs develop for 170-200 days and the young fish appear in April or May. They are carried down into Baikal's bays (“sory”) and then into the open water of the Lake. The omul, which fishermen catch, are usually up to 19 years old and 38 centimeters long, though some fish may live to 25 years of age and be up to 51 centimeters long. The large variety in length of life is one more mystery of the omul! In summer, omul swims near the surface of the water at certain places in the Lake, which are known to fishermen, gathering near the Lake shore at a depth of about 5m. The fish hibernate at depths of 200-300m, close to the areas where they will feed in the summer time. Omul are artificially bred at a fish nursery not far from Baikal on the Bolshaya Rechka river, and half of the fish are released into the Lake. There is a similar nursery in Koma village in the Pribaikalsky District of the Republic of Buryatia. Secret Corners of Lake Baikal Box Numbers of omul were on the increase in the last years of the 20th century, thanks to these efforts to support populations. 96 Are there differences between the omul living in different parts of Baikal? The omul has adapted well to the conditions of Baikal, where it has acquired some specific biological features. There are four sub-populations of omul in the Lake: North Baikal, Chivyrkuysky, Selenga and Posolsk. The North Baikal and Barguzin omul prefer shallow water, while Posolsk and Chivyrkuysky omul live in the depths of the Lake. The small and fat omul, which are caught in the Maloye Morye (the Little Sea) near Olkhon Island are called Malomorsky, and are close to the North Baikal and Chivyrkuysky groups. What other differences are there between these sub-populations of omul? 24-32 сm 0100 m 20 - 22-24 сm the Selenga omul 120 m 32-38 cm the North Baikal omul 180 200 m the Posolsk omul Look at the illustration of different features of omul subpopulations (size, depth and locality)subpopulations The Selenga omul is the most numerous sub-population. It spawns mainly in the Selenga river and in other rivers flowing into Baikal. It lives in the southern trough of the Lake and the southern part of the middle trough. The Chivyrkuysky Omul is the most useful sub-population for fisheries, as it grows very fast, gains mass and can be artificially spawned. The North Baikal group is notable for its small size. It swims up the Upper Angara river to spawn and is therefore sometimes referred to as the Angarskaya omul. It also spawns in the Kichera river and other mountain rivers, as well as in the Chivyrkuysky Gulf. The Posolsk omul is the largest species, and specimens have been found with weight of 5 kilograms and length up to 50 centimeters. 97 Subpopulation Size (cm) Depth (m) Pelagian (Selenga) 24-32 The southern trough of Baikal, the Selenga delta Coastal (North Baikal) 22–24 Chivyrkuysky Gulf, the mouth of the Kichera river, the Upper Angara, etc Bottom-dwellers (Posolsk) 32-38 180–200 Locality Posolsky Sor region Fill in the missing information in the table about various sub-populations of omul. Secret Corners of Lake Baikal Box You might try tasting some omul. The fisherman who eats it with you will tell you of an ancient superstition: if a fisherman falls ill, you must prepare a fish soup of Omul, pass the tail of the fish over the fisherman's lips and feed him the soup. This will surely cure him! Such was people's belief in the marvelous qualities of the omul. The fish is very useful for healthy people too, because it contains much fish fat and vitamins (A,D,E), as well as protein, all of which are good for health and for vision, strengthening bone tissue and raising vitality. 98 Which Baikal fish is called the “Tsar fish”? The Baikal sturgeon – is the largest and most ancient fish in Baikal. Its length sometimes reaches 1.5-1.8 m, and its weight – 100-130 kg. Because of its size this fish got the name «tsar fish». A sturgeon is the only fish that belongs to the group of cartilaginous. Along its body it has outgrowth in the form of plates. It looks like a giant in armours. In Baikall basin basic localities of sturgeon are the delta of the Selenga, the mouths of some rivers and the bays with the depth of 20-50 m. In autumn, sturgeons come to the depth of 150 m, wintering in deep holes in the mouths of big rivers. In April they usually travel to spawn to the Selenga, the Upper Angara and the Barguzin. In the Maloe Sea and in Slyudyanka sturgeons are very uncommon. Sturgeons grow very slowly, by 10 years of age they are 70-75 cm in length and 1,5-2 kg in weight, by 20 years its length can be 125 cm, its weight – 12,5 kg. The male fish mature by the age of 15 and the female fish in 18–20 years. The Cisco or Whitefish closely resembles the omul, but can be easily recognized by its jutting upper jaw. It has small round black spots on its head and dorsal fin. Its head is extended with a more or less cuspidal shape. It can be found only in Lake Baikal and the Baunt Lakes. Baikal cisco are of two kinds: lake and lakeriver. Large numbers of lake cisco are found in the Barguzin and Chivyrkuysky Gulfs, and in the Selenga delta shallows. There are three sorts of Baikal cisco, classified according to their locality: Chivyrkuysky, Barguzin and Maloye Morye. Adult cisco feed on mollusks, plankton, larvae, worms and young goby fish. Numbers of cisco are limited, due to intensive poaching. The ban on omul fishing helped to support populations of Baikal cisco, which are often found in fishermen's catches today. Secret Corners of Lake Baikal Box The total number of fish is not big as this kind of fish was poachered a lot. The ban on omul fishing helped to save the Baikal sturgeon. Nowadays it is often met in fishermen's catch. 99 Another well-known lake-river fish in Baikal is the grayling, which is represented by a Baikal sub-species of the Siberian grayling, occurring in two forms – the black and the white grayling. The Black grayling has bright dense scales, high bright fins. It can be 60 cm long with a weight of 1,5 kg. Graylings are found in all the rivers flowing into Lake Baikal and in the Angara River. In summer, the grayling lives at a depth of 10-20m, and in winter it is found at depths of 3-12m. It diet consists of larvae and adult insects, small crustaceans, and fish roe. The grayling swims for hundreds of meters up mountain rivers with stony beds in order to spawn. When hunting for flying insects, it can leap out of the water to a height of 0.5 m. The White grayling is larger than the black (it grows faster and reaches a weight of 3.0-3.5 kg), and it has less dense scales with red spots on silver gray sides and shorter fins. It usually lives close to the Baikal shoreline at depths of 50 m. Both the black and white grayling live for 10-12 years. Fish Known to Everyone The roach lives in natural water basins all over Russia, but the biggest roach are to be found in Baikal. Local people call the roach a “soroga”, and there are two types of “soroga” in the Lake: a small “sor” fish and a bigger open-water fish. The roach has dense scales and distinctive red fins, and it is the second most numerous fish in catches made by Baikal fishermen. An adult roach of 5-7 years may be 13-15 cm in length, and it can grow to 30 cm when it reaches the age of 11-17. The Sazan is a beautiful fish with golden and yellow scales, dark back and fair belly. It lives only in basins with fresh water. In warm water it feeds actively and it grows quickly. Its maximum weight can reach more than 20 kg. In cold seasons it lies down to winter and stops eating. Every fisherman dreams to catch a sazan, but it requires not only good luck, but good skills, as well. This omnivorous fish became a food fish. It's grown up in ponds almost everywhere. A domesticated sazan is a carp. 100 The best-known fish in Buryatia is the Silver Carp. Its shape the bright silver of its scales give it the appearance of a large coin. The silver carp is numerous in shallow lakes (no more than 3m deep). It is a calm and lazy fish, preferring to stay in quiet spots where there is plenty of slime and no shortage of food. Interestingly, it can live in places where other species die due to lack of oxygen: overgrown basins, drying lakes, and stagnant ponds near Baikal. The carp does not usually grow to more than 30 cm in length, and the specimens found in most lakes are 11-13 cm. Who are those fish-predators? The main predatory fish of freshwater basins is the Pike, and it is also to be found in Baikal. The Pike has a spotty colouring, light bands along and across its sides, with a dark back, and whitish belly with grey specks. Its fins are slightly brown with black spots, and its thoracic and abdominal fins are yellowish-red. The pike is a fairly large fish, up to 80 cm in length, and its grows very fast: by 5 years it weights up to 1 kg, by 12 years it reaches 6 kg, and the fish have been known to grow to 20 kg. The pike has a very long life – 70 years on average. In Baikal a young pike is called “travyanka” (“grass dweller”) because it hides in shallow water where grass grows watching for prey. All fishermen dream of catching a pike. The Taimen – is a large fish of the salmon family. It grows up to 1,5 m long and up to 60 kg. The taimen has a peculiar coloration in different time of its life and in different seasons of the year: more often it is dark, almost black with dark spots on its fair belly. In spawning it covers with crimson spots, and its tail becomes dark red. It swims quite fast; it dashes to its catch very swiftly. Usually its catch is fish, small animals and birds. The taimen is a raptorial fish; it feeds all year round except in the time of spawning. It lives in pure mountain rivers flowing into Baikal, but its number is not high. It is registered in the Red Book. To meet the taimen is a big luck! 101 Its colouring and habits have earned the Perch the nickname of “sea tiger”. It is a predatory fish with a dark green back, yellowish sides with dark diametrical bands, bright red fins, yellow thoracic fins, and orange eyes. Perch are commonly found in all the basins of Buryatia except those, which are closed and shallow. Perch aged 17 years and more than 40 cm in length are occasionally caught. The biggest perch are found in Baikal. The Burbot is another sor fish. It is most commonly found in Baikal and the main rivers that flow into the Lake, as well as in other basins of Buryatia. It is has black-brown spots and bands all over its body, and its belly and neck are of a grey colour. There are two kinds of burbot in Baikal: one that lives in lakes and rivers, and one that lives in lakes only. Ichthyologists note that lake burbots differ from those that also inhabit rivers by their faster rate of growth, high levels of fat on their body a lighter colouring. The lake and river burbot spawns in rivers, while lake burbots are believed to spawn in Baikal, though it is not known exactly where. The burbots lay eggs in the very severe frosts of December and January, sometimes till March and even till May. Its size can be up to 2 m and 30 kg. Its coloring is yellowish-grey with spots but sometimes depending on water it can be dark grey with spots. Usually it is peat brown waters that make burbot have such a coloring. The fish has two dorsal fins and a little barbel on its mandible. Secret Corners of Lake Baikal Box The burbot likes the cold but it spends most of its life in waters with the temperature of 10–12 degrees. In hot summers they are usually passive. They go to hibernation in Baikal at the depth of 100 meters. At the end of summer both kinds of the baikal burbot begin to shoal and go into the depth of 10-15 m intensively feeding on gobies from the bottom. In September burbots approach the shores. During the last years along the southern shore of Baikal burbots have almost disappeared. This fact was probably caused by the work of the Baikal pulp and paper mill and other industrial companies. Fishermen named the burbot a hermit because it doesn't like a sunlight hiding from it at the bottom. Also they don't shoal. 102 Endemics of Baikal Fish that are found only in Baikal include the Goby (both bottom-dwelling goby and another variety, which lives a medium depths) and the oil. The goby family is the most numerous of Baikal's endemic fishes. Bullheads, a variety of goby, are mostly bottom-dwelling. They are small fish and poor swimmers, and their body shape is adapted to life among stones on the bottom of the Lake, where they find refuge. Their dark-colouring is also adapted to this life, since it helps them to blend in with their environment. Fishermen also call bullheads “shirokolobka” (“broad head”) due to the shape of their heads. Some bullhead species can be found along the shoreline, at shallow depths. Different species inhabit areas of water with a stony bottom and areas where the bottom is sandy. Another bullhead type, the Baikal sculpin, form coastal shoals, which are a source of food for omul and various other fish. However, young sculpin escape the predators thanks to an instinctive reaction to the smell, which predatory fish emit. The long-finned Baikal sculpin grows as long as 22 cm. It feeds on plankton, gliding alongside it through the middle depths, helped by its fins and light weight – this manner of movement have earned it the nickname “samoletik” (“little aeroplane”). Fish that live close to the bottom of a water basin are called “bottom-dwelling”. 103 The Oil fish is the most interesting of Baikal's other endemic fish species. It grows to no more than 20 cm and its pinkish body is almost translucent, consisting mostly of fat, so that you can even read a newspaper or a book through its body. The oil fish is very attractive: its surface reflects all the colours of the rainbow, its eye borders are bright orange, and its thoracic fins, which cover half of the body, are almost translucent. Its mouth opens to a width, which is half as great again as the length of its body. There are two kinds of oil fish living in Baikal: the Great oil fish and the Dybowski oil fish (the latter named after the scientist-ichthyologist who first discovered it). Both are found at various depths, but the first is more often close to the bottom of the Lake. Both types can also be kept in aquariums. The oil fish is highly sensitive to temperature: when the temperature drops to 8 degrees centigrade, it is unable to move and becomes numb. Interestingly, the oil fish does not spawn, but puts out live young – the female fish produces up to 3000 grubs, which develop into young fish in spring and summer. Adult oil fish are cannibalistic, feeding on the young of the same species. The species reaches maturity at 2–3 years, so it may live to be 10–15 years old, but no oil fish of such advanced age has ever been recorded. Their main diet are epischuras (up to one million tonnes per year in Baikal). 104 The Lesser oil fish is a sub-species, also endemic to Baikal, living in the open waters of the Lake at depths of up to 1600m. Lesser oil fish feed on epischuras, macrohectopus, and the young of the greater oil fish and of its own kind. It breeds at the age of 2–3 years, bearing grubs that grow inside the fish's body for 90–100 days. There are reckoned to be about 100,000 tons of lesser oil fish in Baikal, and it is an important part of the diet of omuls and of seals. Secret Corners of Lake Baikal Box The oil fish family is very peculiar – so much so that ichthyologists had trouble establishing what group of fish it belongs to. It was at first believed to be a kind of mackerel, then it was related to the codfish family, and only at the start of the 20th century was it established that the oil fish is close to the sculpin. 105 Baikal seal (nerpa) Why do you think the Baikal Seal deserves a special section in our Book? Are there any other names for the Baikal Seal? The nerpa is a large mammal: adults are over 150 cm long and can weigh up to 110 kg. It is endemic to Baikal and is the only mammal living in the Lake. The nerpa is a member of the true seals family (Phocidae) and a part of the Pusa genus. The back of an adult nerpa is silver-gray and its belly is light with a yellowish hue. The female nerpa can live for 56 years and males may live 52 years, and child-bearing age for the female is from 4-7 to 40 years, in which period she can produce over 20 offspring. One pregnancy lasts for 11 months and produces one seal pup. Baikal seals eat fish, particularly gobies, and are also partial to the most numerous fish in Baikal – the oil fish. The creatures can be seen in all parts of the Lake but they are most frequently found in its northern and central parts. In summer the coastal regions along Baikal's shores and its main bays serve as seal rookeries. The biggest seal rookeries are in the Ushkany Islands. Nerpa numbers vary between 50,000 and 70,000. 106 Locals have several names for the nerpa: “ushkan” (“young hare”), “kumutkan”, and “hubunok”. A new born baby seal is called a “belyok”, and it has become one of the best-known symbols of Lake Baikal. In winter, seals live under the ice surface and breathe through airholes, which they make themselves at the beginning of winter and keep open until the spring. Pregnant seals build holes and burrows in the snow layer where they bear their pups. At the end of the winter and the beginning of spring seals come out onto the ice to bask in the sun.. At this time seals are vulnerable to poachers: the fur of young seals has a high value on domestic and international markets (it is used for making hats and coats) and nerpa fat is used in the tanning industry and for soap. Seal meat is also edible. Secret Corners of Lake Baikal Box Scientists believe that the Baikal seal has a common ancestor with the well-known northern seal, and that the animals reached Lake Baikal by travelling from the Arctic Ocean along the Yenisei and Angara rivers. This must have happened during the Ice Age, when the rivers were locked in ice from the north. Other scientists believe that the nerpa came to Baikal via the Lena river, which was linked with the Lake before the Ice Age. 107 A seal – is a very cautious and timid animal. To see it in nature is very difficult. In order to watch it and to study this unique mammal, a lot of house-houses were organized on Baikal. There are three of them: in Irkutsk, in Listvyanka and a summer seal-house in the settlement of Sakhyurt. The biggest one is situated in Listvyanka, it was opened in summer, 2009. There one can see trained seals which can sing, dance, paint, play with a ball. Animal-trainers say that it is quite difficult to work with seals, because they are very independent animals. The most important task of creating seal-houses is study and preservation of this Baikal endemic, one of the three species of freshwater seals. In natural conditions the main enemy of the seal is a man. Seal-hunting is still allowed, though the number of these unique animals according to some data doesn’t exceed 100 thousand specimen. In seal-houses scientists study their ration and way of life, watch seal pups born in artificial conditions, plan ecological actions on protection of the Baikal seal. 108 Think, Play, Experiment, Create together!

How wonderful to see with our own eyes who lives in this crystal tower! We will write down everything we see in our exercise books and create a cut-out collage using photos. The depth – 150 m On the starboard side there are rocky walls. The omul likes to spend its time at such a depth. It can grow as long as 50 cm, weighs up to 5 kg, and can live for up to 25 years. But only one of about one hundred roe will survive to become a fish. The number of roe who survive depends on the purity of water. The depth – 200 m A sturgeon swims by – the Tsar Fish of Baikal. Sturgeons live for 50-60 years or more and sometimes weigh as much as 100-130 kg. They grow very slowly. Over-fishing has reduced Baikal's stocks of sturgeon and the fish has been included in the Red Book. The depth – 380 m Here he is – the famous oil fish! He is light pink in colour. The females do now spawn eggs, but eject 2000 or 3000 tiny fish into the water. The body of the oil fish is translucent, so you can read letters on white paper looking through its tail. Fishermen do not take oil fish, because they melt at a temperature higher than 8 degrees above zero. They spend most of their lives very deep underwater. The depth – 500 m Through the porthole you can see silver oil fish and planariidae. It is a beautiful sight. We are recording them with a colour cinema camera. 114 Now let's put all the sea creatures we have just seen on these pictures. 115 I am a creator! A cut-out collage with Baikal birds Put the cut-out pictures of various birds on the photographs of Baikal, matching the birds to the scenes that are shown. We have a Yellow-legged Gull, a Mallard, a cormorant, a sandpiper, a heron, a wagtail and a dipper. 116 117 I am a creator! A creative task Free the stones of Baikal from an evil spell You will learn: · see something wonderful around you; · dream and share your dreams in the process of painting; · make up souvenirs with your own hands. These will be necessary for you: stones from Baikal, acrylic or tempera paints, brushes, pencils (lead or wax), transparent nail polish, some water and several napkins. For the first time we advise you to use the help of your teacher or adults! The work order is as follows: First of all, read a fairy-tale. A long time ago all the shore of Baikal was covered with cliffs. Then winds and rains broke the cliffs down into stones. Now imagine a kingdom of stones under an enchantment, and imagine that our stones are the citizens of this magic country. They used to be people, living in peace and friendship, never quarreling (just like you and your classmates!). But one day a wicked wizard whose name was Envy learned about that country. He called Greed, Indifference and Hatred to his aid and they decided to cast an evil spell on the magic kingdom. The wicked magicians turned the citizens of the magic country into grey soulless stones. They would have been left lying on the shore if a kind fairy called Rainbow and her little rainbows has not appeared. You can help our little rainbows, using brushes as magic wands to bring to life and remove the enchantment from the citizens of this wonderful country. 118 Before you start you should learn some magic spells. Otherwise the magic won't work. Repeat after us: · We are little rainbows! · We are not afraid of brushes and paints! · We are ready to help the citizens of a magic country! On your stones you can draw birds, animals, fish, flowers, berries, waves, Baikal shore, mountains. Let this easy rule help you: “The person who wants to succeed succeeds, and the person who succeeds can do everything!” You can put yourself in a creative mood by turning on your favourite music! Have you chosen what you will paint on the stones? Let your teacher or another adult help you when you first start! Do the following: 1. Take a good look at the stones (you can find them on any walk along the shores of Baikal) 2. Now dry it with a wet napkin. The stone is ready to be painted! So, dear rainbows, let's start creating magic! Let's apply the image onto the stone in a lead pencil. Now let's start to paint it. 3. Let's protect the stone from rains (cover it with polish). Leave you stone for 2-3 minutes. Don't touch it for 2-3 minutes in order to make it dry. 4. Admire the images on the stone. Well, yes, they look like alive! The magic works! 5. Think who you can give your souvenirs to? 6. Invite your friends to paint other stones. You can make an exhibition of your works in a class or at school. So, children, not only have you removed the spell from the fairy-tale – you have also learned to dream and convey your fancies through drawing. But the most important thing is that you have made beautiful objects with your own hands. 119 I am a creator! Let's paint a seal pup 120 I am a creator!

Now we are going on a fascinating journey along the secret paths of the region around Baikal. You will learn many interesting things from Lake Baikal Box, which will help you choose your own route, find out more about the unique natural environment round Lake Baikal, and – most importantly – to understand why Baikal needs our love and protection. It is common practice nowadays all over the world to set up specially protected natural territories – nature reserves – to protect unique wildlife and landscapes. The purpose of a nature reserve is to protect endemic and rare species of plants and animals, many of which have been registered in the Red Books of plants and animals of Russia and the Republic of Buryatia. Red means danger – like a traffic light – because these plants and animals are in danger of dying out. There are four types of nature reserves: protected areas, national parks, nature sanctuaries, and so-called “natural monuments”. Specially protected natural territories – are places, where any human activity is either limited or prohibited. Children, do you know which are the most famous wildlife areas and national parks in the world? Yellowstone (USA) is the world’s first national park, created in 1872. The Great Smoky Mountains national park has the world's longest continuous foot path, which make its particularly popular with hikers. 126 The Great Barrier Reef is a national sea park off the coast of Australia and is also a UNESCO World Natural Heritage site. This great underwater ridge consists of nearly 3000 coral reefs and islands, and is one of the world's natural miracles. The unique Askania-Nova protected area in the Kherson Region of Ukraine was created in the late 19th century by Fridrikh Falts-Fein, a large landowner in Tavrichesky Province who loved and knew a great deal about nature. It remains the only piece of steppe landscape in Europe, which has never been ploughed up. There are very strict rules as to what you can and can't do in a nature reserve. Hunting, fishing, gathering medicinal herbs, large-scale tourism, building of hotels, rest zones, and asphalt roads are all forbidden inside protected areas. UNESCO is the United Nations organization that deals with educational, scientific and cultural issues. The Red Book is a list of rare animals, plants and fungi that are in danger of disappearance. 127 Specially Protected Natural Areas Nature reserves have also been created round Lake Baikal: our Lake has 4 protected areas, 3 national parks, and 22 nature sanctuaries. They include the Baikal-Lensky protected area and the Pribaikalsky national park (both in Irkutsk Region) and a number of territories in the Republic of Buryatia. You can find some of them on the map. 128 Nature reserves We will start our journey from the Barguzin Reserve – the first and oldest nature reserve in Russia. It is bestknown for the Barguzin sables, which live here. Sables were driven close to extinction by intensive hunting at the end of the 19th century, and a strict hunting ban was needed to save them. This was the purpose of the Barguzin Reserve. In 1996 the reserve was included in UNESCOs list of world cultural and natural heritage sites (representing Lake Baikal) A protected natural area is a natural territory where shooting of wild animals and gathering of plants are prohibited – they are places where you can experience nature untouched by man. Secret Corners of Lake Baikal Box Siberian hunters called the sable "askyr", the Mongols "bologan", the Evenks "dynka", and the Yakuts gave it the short but expressive name, "kis". In ancient times the sable was considered to be "a diamond", or “soft gold” because it was used as a means of payment instead of money. Suvinsk rocks Baikal lake coast In the Evenk language “Suvoya” or “Suvi” means "whirlwind". The Buryats believed that the land of the Barguzin reserve belonged to two mythical characters, Suvo Tumurshi –noion and his wife Tudugish–hatan, in honor of whom a wooden shine had been built here. What is special about the Barguzin Reserve? The reserve includes several natural belts: tundra, Alpine meadows, and taiga. There are also a number of hot springs in the reserve, and 17 rivers rise on its territory and flow into Lake Baikal. 129 What grows in the Barguzin Reserve? An amazing variety of plant species grow in the Barguzinsky Reserve – about 900 in all – and they include several rare species that are in need of protection: the butterfly orchid, a particular kind of tussock grass, ladies' slipper, Snowdon rose, and many others. What strange names plants have! Children, why do you think we give them such names? Ladies' slipper is also known as “Venus's shoe”. According to the legend, the Goddess of Love, Venus, wore unusual footwear – shoes made of flower petals. Whether or not that is true, the flower certainly looks like a shoe, and hence the name. There exist about 50 species of this plant. Ladies' slipper is found in South and North America, in Europe and Asia, and from the forest-tundra to the tropics. It doesn't bloom until it is 18 years old! Its flowers are very large, up to 8 cm across, violet-red with a network of crimson veins. The flower "hides" under the leaf when it rains, so it never fills with water, even during heavy rain, but always contains a few drops of dew. Snowdon rose is a well-known perennial medicinal plant. It has fleshy oblong leaves and small yellow flowers, grows slowly and loves moisture. Its folk name is “golden root” and it is also called “Siberian ginseng”. The root is used for medicinal purposes and takes 8-10 years to reach maturity. It is called “golden” not only because of its colour, but also because it helps to restore a person's energy, eyesight and hearing, and was therefore considered to be of great value. According to ancient beliefs, a person who finds the golden root will live a long, lucky and healthy life. The Ghost orchid (in Russian, the “Over-chin”) is a rare perennial species. It has no green leaves, and its stalks are fragile, coloured a hollow light yellow with red strips. There are from two to eight flowers on the stalk, which is 30 cm in height. These gentle flowers attract insects by the light smell, similar to banana, which they give off. Its coral-like rhizome is mass of fungal threads, which the plant used to find nutrients. The ghost orchid grows in shady coniferous and mixed forests. It blossoms plentifully in rainy weather with thunder-storms. Botanists gave the plant its unusual Russian name due to the arrangement of its petals, which looks like lips over a beard. 130 Barguzin Reserve fauna The Barguzin Reserve has a rich and unusual fauna: 39 species of mammals, 243 bird species, 4 species of reptiles, 2 types of amphibians, about 30 species of fish and a great number of invertebrates. The best-known inhabitant of the reserve is the Barguzin sable, which lives in taiga solitude amid cedar thickets from which it extracts its favorite delicacy – nuts. It also hunts for fish, squirrels and other small animals (ermine, rodents and birds). The sable can also be vegetarian, eating cowberry, bilberry and mountain ash berries. The most interesting thing about the sable is that the colour of its fur depends on where it lives: the further north and the higher the mountains, the darker its fur. The Barguzin sable is the darkest and its fur is valued most highly. Sables with light fur live in various places from the Urals to the Yenisei river. The Chernoshapochny (“black hat”) groundhog lives only around Baikal. It takes its name from its colouring, since it is brown all over except for a darker stain on the head, which looks like a black hat. The black-hat is the smallest sub-species of groundhog (22,400 individuals), and they live in separate families, each with its own wintering hole. The families usually live on dry, southern slopes of mountains and hills with light snow cover. Groundhog holes are not deep (from 20 to 70 cm) and have many exits. In cold autumns and winters the groundhogs stop up the holes with dry grass to keep more heat. And this small animal was called the Northern creeper because of a whistling sound. The creeper produces whistle as if it 'talks', or warns about some danger. It looks like a hare with a short tail and the rounded-off ears, it has smooth fur of brown or grayish and yellow color. This small animal is a vegetarian, it eats grassy plants and branches of bushes. All creepers are remarkable mowers. They bite grass with their sharp teeth, drag it to the holes and display so that it gets dried. Therefore the creeper has the second name – «senostavka». What's more hunters guess about weather judging by their behavior: if there is no grass brought by creepers on stones, it'll rain. 131 The Musk deer is the smallest representative of the deer family. It can be met in Buryatia in almos every mountain and taiga regions. Its body's length is 80-100 cm, height in wither is up to 80 cm, its weight is about 15-20 kg. Neither females (cows) nor males (bucks) have horns. Mature bucks have fangs with the length up to 10 cm, which stick out of the upper lip. Also they have a musky small bag on the inner side of the hip. About 40–50 g of musk can be gathered in the bag. It is well-known as «a musk deer's stream». The musk is valued in perfumery industry as a holder of smells. Also it was widely used in medicine. In summer the deer eats woody or ground lichens, thin branches, sprouts, needles and plants. In winter it eats woody lichens and bark, branches. It eats at night and in twilights. It spends a day liing near rocks, among stone placers. A musk deer is a very cautious animal. It moves jumping, climb different rocks well, thus escaping from enemies. Escaping from pursuers a musk deer fouls the trails. It is sometimes difficult to grasp in them. A she-musk deer is a self-sacrificing mother. At any signs of alarm she, risking her life fearlessly, rush onto the enemy, while little deers hide in safe places. A musk deer is a unique animal; it's a decoration of our taiga. Barguzin's rare bird species Barguzin's rare bird species include the sea eagle, golden eagle, black stork, and osprey, and the gray crane can be seen nesting on bogs. Let's find out more about the birds we can meet along Baikal's secret paths. There are seven species of eagles around Baial: the steppe eagle, golden eagle, imperial eagle, great spotted eagle, dwarf eagle, whitetailed sea eagle, and long-tailed sea eagle. Secret Corners of Lake Baikal Box Eagles are treated with great respect by the Buryats, and there are many legends associated with the bird in the area around Baikal. A fearsome spirit is believed to inhabit Olkhon Island and to assume the shape of a white-headed eagle. The Buryats still believe that a person who kills or wounds an eagle will soon die himself. This reverence for the birds is one reason why they continue to flourish on Baikal, while in other parts of the world eagles have become endangered. 132 The Steppe eagle is large and beautiful. It weighs from 2 to 5 kg, has wingspan up to 2m, and its head is dark-brown in colour. Young eagles stand out from old birds by well-defined strips on the underside of their wings, longitudinal motley specks on the belly, and brighter plumage. They grow the final feather in their “dress” in the fifth year of life. The steppe eagle has a very unusual way of hunting. It watches for and catches rodents at the exits from their holes. The eagle can lay motionless on the ground for hours with its head close to a hole until the gopher or vole emerges, to be struck with a powerful blow from the eagle's beak or claws. The White-tailed sea eagle is the largest predator nesting in Baikal Region. It stands out by its long "rectangular" wings, a wide, short, wedge-shaped tail, and a small head which is much lighter than the rest of the plumage. The sea eagle has a large and powerful beak of light yellow color. Unlike the golden eagle, its feet are not covered with feathers. The sea eagle reaches its adult appearance aged five, after which its tail becomes white. The sea eagle seldom catches strongly swimming fish, but usually picks up sleepy or dead fish from the water surface, as well as fish thrown ashore by a storm. The Black stork is another rare Baikal species. These birds fly to the lake in early May, having already found a mate, and feed on fish, frogs, tadpoles, and crustaceans in shallow rivers. They build their large nests (1-1.5m) on the open banks of rivers and lakes, or in the remote taiga and lay two or four eggs of a grayish-white color. Both male and female birds sit on the eggs for more than a month. These graceful birds fly away in September in family groups of three, four or five birds. 133 The Dzherginsky Nature Reserve The Dzherginsky nature reserve is located in Kurumkansky District of the Republic of Buryatia, in a unique position to the north-east of Baikal where three large mountains – Barguzinsky, Ikatsky and Southern Muysky – meet. This is a high-mountainous place with a distinctive natural environment where the stony tundra mixes with Alpine meadows, thickets of cedar shrubs and dwarf birches. More than 650 species of flowering plants are to be found here. Secret Corners of Lake Baikal Box The most ancient inhabitants of these places, the Tungus, called the territory where the reserve is now located “yarga”, which in their language meant “sacred” or “happy”. The present-day name, “Dzherginsky” derives from that word. Types of plants at the Dzherginsky reserve divide into forest-steppe, taiga and high-mountainous. The Daurskaya larch is dominant in the forest zone, having soft and fragrant needles, which fall every autumn, like the birch. The tree is much loved in Siberia for its beauty, aroma of fresh needles, the intense heat it gives when burnt and (most of all) its quality as a building material – it is very dense and doesn't decay in water thanks to the large amounts of resin that it contains. The Italian city on water, Venice, which is more than 1000 years old, was build on Siberian larch. The larch can live for 500600 years. Herbs also grow in abundance, including Camel's tail, which has anti-inflammatory properties and is registered in the Red Books of Buryatia and Irkutsk Region. Camel's tail is a peculiar, highmountain plant that grows to a height between one and five meters, with thick branches having four to six pairs of leaves. Its flowers contain oils, ascorbic and other organic acids, sugar and pitch. The upper part of the plant is used in medicine. 134 The Dzherginsky reserve has diverse and very interesting fauna: 43 species of mammals, 145 bird species (including 118 nesting types), 3 amphibians, 4 species of reptiles, 6 fish species, 839 species of insects, 164 species of spiders, and 39 species of protozoa. Mammals include the white hare, squirrel, wolf, fox, brown bear, sable, glutton, ermine, weasel, river otter, lynx, wild boar, roe, elk and reindeer. Local amphibians include the Siberian frog and a Far Eastern tree frog. Main reptiles are the viviparous lizard and copper-head snake. Water spaces at the reserve contain graylings, burbot, river minnow, greenling and taimen. Bird inhabitants include the black-throated loon, black stork, whooping swan, swallow, tealcracker, mountain duck, partridge, black grouse, stone wood-grouse, hawk (teterevyatnik), buzzard, imperial eagle, a golden eagle, white-tailed sea eagle, gyrfalcon, owl, and eagle owl. Of the reserve's bird inhabitants, the black stork, black crane, and whooper swan are under special protection. The white-winged Whooper-swan is a proud and handsome bird, and the hero of many Baikal fairy tales and legends. It has a long neck, magnificent, snow-white plumage, a yellow beak, black feet and a loud, trumpetlike voice. The swan moves with effort on the ground and takes off with a long run-up. It is both a carnivore and herbivore, and finds forage in water by immersing its long neck. Its preferred nesting place is on the Chivyrkuysky Gulf. The birds arrive at nesting places in pairs in late April or early May Secret Corners of Lake Baikal Box It is known that couples mate for life (hence the folk expression, “faithful as a swan”). According to ancient legends, several Buryat tribes – the khori and hongodory – originated from swans. The Black-necked grebe is a small bird of black colour with red sides, a white paunch and a dark gray beak. In spring the bird produces a loud whistle, which then turns into a trill. The birds nest together in flocks, and feed on water insects, larvae, crustaceans and mollusks. 135 What are the main types of fauna at the Dzherginsky Reserve? The Lynx is the fearsome master of the taiga – a dangerous predator of about 19 kg, whose main weapon is a sudden attack and who hunts only at night. It is a tree-climbing member of the cat family with strong hearing and sight, which uses its whiskers as tactile organs. The lynx has reddish-gray, dense and soft fur. The Wapiti stands out from other deer by the bright reddish colouring of its wool in the summer and darker colouring in the winter. The animal lives in the mountains and mountain river valleys, and is a good swimmer. Its winter forage is dead grass, and plants, which it extracts from under the snow, and in summer it eats leaves and the shoots of trees and bushes. Children, which do you think is bigger, a wolf or a dog? Usually a male wolf weighs about 50 kg, and a she-wolf weighs about 5 kg less. Their height to the shoulders is about 75 cm, and their length from nose to the tip of the tail is 1.5-2m. Wolves are created by nature for hunting. In winter wolves leave a neat path through the snow, putting their back leg precisely in line with the front leg. This gait enables the wolf to run even on deep snow. the wolf's weapon are its teeth: it has 42 teeth, of which four points outwards – two 5 cm curved canines above and two below. Wolves hunt almost silently, thanks to their gait. Their keen sense of smell means that that they can pursue prey over long distances. 136 The Baikalsky Reserve The Baikalsky National Biosphere Reserve spreads over parts of three districts in the Republic of Buryatia (Kabansky, Selenginsky and Dzhidinsky Districts) and is bounded by the Khamar-Daban ridge and the southern coast of Lake Baikal. The Baikal Reserve was set up in 1969, covers about 165,000 hectares and has a perimeter of 200 km. The Baikalsky Reserve is 30% Alpine highlands and 70% taiga and has 160 lakes in its confines, thanks to which it is of international importance as a wildfowl habitat. Its major purpose is to support biological diversity. 137 787 species of plants grow in the reserve, including 180 herbs, and 50 species are included in the Red Books of Russia and Buryatia. What plants do you recognize in these pictures? Rare species include an endemic tree, the Baikal swertia, which grows only in Khamar-Daban. It has wide roundish leaves, dark-violet flowers shaped like stars, and a poplar fragrance. The Swertia grows to a height of 30m, and its trunk is about 1.5m in diameter. The Blue spruce is another tree of much interest, remarkable for the gray-blue colouring of its needles, cone-shaped crown, and horizontally growing branches. The tree is frost-resistant, and unfussy about its soil, capable of growing even in an urban environment, and can live for 400-600 years. The tree's ancestral home is in North America. Baikal swertia Sweet poplar 138 Blue spruce The Wild rosemary. It's a well spread bush with its height up to 2 m, of the heather family. A wild rosemary grows in Eastern Siberia, it often makes tangles in piny and larch forests. The leaves blossom out after florescence. Flowers are of elliptical form, individual, pink. In Greek the name means «a pink tree». A wild rosemary is a harbinger of Baikal spring. Florescence of a big amount of pink flowers, especially when greenery hasn't appeared yet, makes a feeling of blooming garden on the coast of Baikal. These amazing flowers start blooming in May–June. Sprouts and leaves give a strong aroma which causes guidiness. All the parts of the bush are poisonous, and they cause nausea. 139 Fauna at the Baikalsky Reserve include very rare species such as the osprey, golden eagle, sea eagle, black stork, and eagle owl, which feature in the Red Books of Russia and of Buryatia. Birds worthy of mention at the Reserve include owls and taiga flycatchers. The Owl is a non-migratory but wandering bird and very large: 63-66 cm long and with wingspan of 130-140 cm. It weighs 1 kg on average, eats rodents, and hunts during daylight hours. The owl rarely builds its own nest (at the tops of broken trees, high from the ground) generally preferring old nests of other birds. The owl is a symbol of wisdom. The Taiga flycatcher is a red breasted bird, which attracts attention by its unusual violin-like song, which sometimes turns into a sound like the crack of a dry tree. The flycatcher arrives in May and flies away in September, living in high trees of the mountain woods. It builds nests on branches by the tree trunk, and lays 4-8 olivegreen eggs with red-brown spots. As the name suggests, flycatchers feed on various flying insects. Other protected species at the reserve include the River otter, a dexterous and flexible animal with short, roundish ears with valves which keep out water when the otter dives. Its legs are short, with membranes between the claws, and its front paws are shorter than its back paws, which helps it to swim well. The animal has a long brawny tail. The otter's fur is waterproof, which helps it to keep warm. 140 The Chipmunk. This small animal with an elongate body and a long tail can be found in the whole forest zone of Buryatia, The body's length is 13–16 cm, the tail's length is 8–10 cm. The color of the body is red with dark lengthwise stripes. It lives in coniferous and mixed forest, in bushes on the coasts of rivers and low forest. It climbs trees, lives in holes or fallen tree holes. The chipmunk leads a daylight way of life. It eats seeds of coniferous trees, berries, grass, mushrooms mainly. Also it eats insects, worms, birds egges. By autumn time it already has rich stores, sometimes about 5 kg of cedar nuts which it eats in the early spring. A shechipmunk can have 4–5 cubs. In a month they start walking out of the hole, and in two-monthold age they lead an independent way of life. In September-November the chipmunk falls into hibernation. It wakes up in April–May. The chipmunk is not afraid of a man; it gets used to a man quite quickly and can live not far from his dwelling You know the Brown bear from fairy tales, legends and poems, and it was also the symbol of the 1980 Olympic Games in Moscow. The bear looks clumsy and slow – to call someone “as clumsy as a bear” is proverbial. But this is a false impression: in fact, the brown bear is dexterous, fast, a good swimmer and capable or swarming easily up trees. Its claws are long (about 10 cm), sharp and of a black color. It can easily break an elk's spine with one blow, and it stalks its prey silently despite is huge weight. The bear is also skillful fisherman, and has a sweet tooth that makes its partial to honey. The bear sleeps in its den for nearly half a year, and lives for more than 45 years. Hunting brown bear hunting is strictly limited. 141 The Baikal-Lensky Nature Reserve This reserve, which was created in 1986, takes its name from Lake Baikal and the Lena river, one of Russia's greatest rivers, which rises here and flows northwards to the Arctic Ocean. It is the largest of the reserves around Lake Baikal, covering an area of 659,000 hectares in two districts of Irkutsk Region. The reserve was set up to ensure protection of the environment during construction of the Baikal-Amur railway, which was accompanied by widespread tree felling and a number of forest fires. The Baikal-Lensky Reserve is home to 47 plant and animal that are endemic to Siberia, and 31 protected species of flowering plants, 11 of which have been included in the Red Book of Russia. Two types of bulb plants are of particular interest, as are various rare species of mushrooms and lichens. This is the only part of the Baikal mountain ridges where one can find such endemics as the Baikal sulla, sharp-leafed oxytrope, cotoneaster tjuliniae, and Popov's poppy. Turchaninov's tussock grass is a Baikal endemic, registered in the Red Book of Russia, which grows on sands and stony slopes. It is 20–60 cm high with narrow leaves and is also found at the Barguzin reserve. The Altai onion is a perennial grassy bulb plant of the herb family, which flowers in early June. It is used in traditional medicine as an antimicrobic and a tonic to improve digestion. 142 The Siberian globeflower, more known as a “flameflower” is called in honor of its brightlyorange color. It is a grassy perennial plant, an early blossoming decorative plant. It grows in coniferous and mixed forests, on forest clearings, meadows. The flowers are large up to 5 cm in the diameter. In the past the flowers were used for painting fabric into a yellow color. The Siberian globeflower is a quickly blossoming plant; it blooms for about 20 days (from the beginning of June). The seeds are spread from the second decade of July. The Siberian globeflower is a medical plant. It has an antibacterial action. In the Tibetan medicine it is used for treating eye-sight weakening; in Mongolian medicine for treating diseases of gastrointestinal disturbance and as a tonic. The melliferous flower is registered into the Red Book of Buryatia. 143 The Baikal-Lensky reserve has a great variety of fauna, including 261 bird species, of which 18 types are registered in the Red Book of Russia, and 6 are in the Red Book of the International Union for the Conservation of Nature (the white-tailed sea eagle, bustard, imperial eagle, Baikal teal, osprey and greater spotted eagle). Many native animals of the taiga are also to be found here: squirrels, sables, elks, chipmunks, and red-gray voles, and birds such as the nutcracker, wood grouse and hazel grouse. Animals that can be found in the high-mountain tundra include wild reindeer, white and tundra partridges, and the black-hat groundhog. Steppe fauna include the long-tailed gopher, daurian jackdaw and ruddy shelduck. The symbol of the Baikalo-Lensky reserve is the brown bear, which lives here in large numbers, and the Lake shoreline of the reserve is even known as the “brown bear coast”: in the early summer six or seven bears can be seen on the beach at once time, absorbed in hunting for caddis flies, bullhead fish and fish spawn. There are about 15 species of fish living in water spaces at the reserve. The Lena river is inhabited by a Siberian grayling, common cisco, lenok, whitefish and burbot. Pike and perch are found only in the Northern Lake on the Pokoiny cape. Taimen used to live here before the reserve was established and there are plans to re-introduce them. Dwarf forms of the grayling and the Siberian loach are found in mountain lakes, and minnows swim in the local rivers. Moor frogs and Siberian wood frogs are to be found at the reserve, particular in the Lena river valley, as well as the Siberian salamander. This amphibian is particularly fond of taiga river valleys, the shores of lakes, bogs with high grass, and damp meadows. The salamander grows to about 16 cm, half of which is its tail. It has a wide head, which is slightly flat, and four short legs. The top part of its body is brown, its stomach is lightcoloured, and it has dark patches all over. Siberian salamanders migrate to shallow, well-warmed water spaces in order to breed. They spawn in May-June, attaching the spawn to water plants or stones. The larvae develop for about a month, and young salamanders take to the land in July-August, where they feed on spiders, flies, land mollusks, and grasshoppers. They go into hibernation in the second half of September or October. Salamander populations have declined due to the destruction of habitats and pollution of water spaces. 144 National parks Unlike reserves, the purpose of national parks is not only to protect unique flora and fauna, but also to enable people to admire it. There may specially reserved zones in national parks where rare plants and animals are found, as well as human settlements that still observe a traditional way of life. National parks are protected by strict rules, in the same way as nature reserves. National parks are extensive natural territories with remarkable landscape features, where various outdoor tourist activities and educational tourism are encouraged, provided that the natural environment is carefully protected. National parks are open to visitors, but groups and individual visitors must be registered by the park administration and show the route plan for their visit as well as the estimated time of their return, thus ensuring protection of the environment and the safety of the visitors themselves. 145 The Tunkinsky National Park The Tunkinsky national park was established in 1991 on an area of 11,836 square kilometers and is among the largest national parks in Russia. The distinctive feature of the park is the combination of nature protection with active economic activity (agriculture, wood industry).The park combines protection of nature with various economic activities (agriculture and forestry), as well as popular tourist resorts (Arshan and Nilova Pustyn), and hot and cold springs with curative properties. The park occupies the whole of the Tunkinskaya valley, the Khamar-Daban and the East Sayan Mountains, including the peak of Munku-Sardyk (3491 m). Some 68 plants species at the park are registered in the Red Books of Buryatia and Russia, including the Tangut aconite, which is now threatened with disappearance, and the Sayan buttercup, which grows in the Alpine belt on damp meadows, near springs, on the edges of streams, and along the upper reaches of the Ekhe-Ugun river. 146 The Megadeniya Bardunova is a mediumsized plant of the cruciferous family, named after a distinguished botanist and biologist, Leonid Vladimirovich Bardunov, who discovered it as recently as 1953, when he was a student at Irkutsk University. Only very few samples of the plant have been found. It is an annual, stemless plant with rounded, heart-shaped leaves having small, white flowers, which grow close to the root on very short peduncles. Many plants that grow in the Tunkinsky park have medicinal qualities. They include the Juniper, an evergreen coniferous bush that grows to 1-3m. It is found in mountainous habitats and is used in traditional medicine as an antiinflammatory and disinfectant. Infusions and broths made out of juniper fruits are useful in treating diseases of the respiratory organs. Juniper oil is used as a balm for rheumatism, gout, etc. The juniper has a pleasant smell. The Buryats have a very high regard for the juniper and use it as a means of purification: juniper smoke is believed to lift evil influences from houses, objects and people. Secret Corners of Lake Baikal Box The larch-unikum is found around the Arshan tourist resort. This tree has diameter of 1.2 meters, grows to a height of over 30m and can live for more than 500 years. 147 A number of rare animal and bird species, which figure in the Red Book of Russia, are also to be found in the Tunkinsky national park: reindeer, Siberian mountain goat, red wolf, snow leopard (irbis), beaver, golden eagle, eagle-owl, and black stork. The Reindeer is another “athlete” of the national park. The animals weigh 150 kg, are more than 2m long and about 1.2m high to the shoulders. Reindeer are stocky, with large hooves and roundish, short ears. Both male and female animals have horns, which are arch-shaped and usually directed forward. Colouring in the winter-time is gray (close to white) and in summer the hide takes on a brown shade. Reindeer that live wild have less distinct colouring compared with those, which are herded by the local inhabitants Wild reindeer feed mainly on lichens. In the summer they eat grassy forage, mushrooms, and cowberry leaves. The Siberian mountain goat is a large animal with big, sabre-like, back-curved horns, which continue to grow throughout the anima's life. The beard is dense and long, and the animal's hooves are perfectly adapted to swarming up stones and rocks. The goat eats cereals, beans, grass, and onions. The female gives birth to 1-3 young. Secret Corners of Lake Baikal Box The Khamar-Daban deer population is remarkable for having a small share of calves – 8.2 %, so the number of animals is decreasing year by year. This effect and shinkaage of the areas over which the animals roam has been caused by human activity (hunting, fires, wood cutting). The deer are also preyed on by wolves, wolverines and bears. The animals are not shy of humans, so they can easily fall victim to hunters. They are relatively safe only in virgin landscapes, where they seldom come into contact with humans. The Eagle owl differs from other types of owls by its large size (it is nearly as large as a domestic goose), its colouring, and black, feathery ears. It has a strong, low-pitched call (sounding like "u-hu-huuu"). Its colouring is usually red or ocher, and the male and female birds both look the same. The birds have yellow eyes. One-year old baby birds are already similar to their parents. The adult eagle owl weighs 2–3 kg and lives for about 20 years. The most interesting feature of the eagle owl is its ability to turn its neck by 270 degrees. The bird has bewitching eyes, which can see in the dark. Its diet is highly various, including voles, mice, gophers, groundhogs and chipmunks, which it catches at distances up to 7–10 km from the nest. The eagle owl begins its hunting at the end of the day. The birds mate for life and are highly territorial. 148 The Zabaikalsky National Park Visitors to Lake Baikal are always keen spend time in the Zabaikalsky national park. You could be their guide. Here is some information that will help you: the park was founded in 1986, it covers an area of 267 000 hectares, and contains 17 outstanding natural landmarks, many of which were tourist attractions since before the park's creation – the Ushkany islands, the Chivyrkuysky Gulf (the most beautiful bay on Baikal), the Svayatoy Nos peninsula, and Lake Arangatuy. Remind guests that they must keep to the paths and only make halts at specially designated places. You are already familiar with the Svyatoy Nos peninsula. You probably remember that there are three settlements on the peninsula. But do you remember the main occupations of their inhabitants? The most attractive and most visited place in the national park is the Chivyrkuysky Gulf. Its extends for 25 km and has water depth between 5m and 10-15m (in the central part). There are 7 islands in the Gulf (access to visitors is limited). 149 You have already met several of the plants, which are to be found in the Trans-Baikal national park, including the Snowdon rose. In total there are about 1000 species of flowering plants in the park, of which 19 are endemics. A relic is a type of a plant or an animal having preserved since the most ancient times. You could make a story about one unusual tree that is to be found in the park, the chozenia. Visitors would be interested to learn about this relic species of the willow family (a “relic” species is one that has survived from very ancient times). The Crowberry (Empetrum sibiricum V. Vassil) Crowberry (Black crowberry) is a small berry of black color. It's eatable, stony, almost tasteless, neither sweet, not sour. It is an evergreen branchy bush of the Empetrum family; its height is up to 25 cm. Long up to one meter, dark-brown stalks of black crowberry creep on the land; their ends rise up. With cold period they get dark obtaining violet-black color. The crowberry's branches look like branches of a coniferous tree bacause they are covered by small leaves reminding needles. The leaves are small, dark-green, stiff, subulate. It starts blossoming as soon as snow melts. Its flowers are small, tripetalous, pink or dark-red. They turn into fruitage – black with grey bloom juicy berries. People gather the crowberry in August. Apart fro the coast of Baikal the crowberry can be found on the subalpine mountain zone of Eastern and Western Sayans. Young sprouts of the crowberry are used as a medical means. The Cowberry is a perennial plant. It grows on dry and damp coniferous forests, in bushes, sometimes on peat boggs. The plant's root is horizontal with rising branchy sprouts 15–20 cm high. The leaves are coriaceous, on short leafstalks, elleptical, with declinate edges. Cowberry's globe-formed fruitage of red color on the background of green leaves, are eaten by animals and birds. Decoction on the leaves is ised in medical purposes. Tea with cowberry jam is a good sudorific. For a long storage fresh berries are covered with sugar or water. Frozen berries are especially good for gamebird, also it is used for making sweets filling, marmalade, fruit drink and jam. 150 The park also has a huge variety of fauna, including several species that registered in the Red Book of Russia. Bears, reindeer, black-hat groundhogs, wapiti, elks, red deer, sables, squirrels, foxes and wolves are all to be found here, and water spaces in the park contain otters, a muskrats, and Baikal seals. Looking up to the sky you can see white-tailed sea eagles, whooping swans, black cranes, and black storks. You can also see a bird we have not met before – a member of the falcon order. What is it? Find out more about it. Sapsan Falcon The Grass-snake. This rare not nymerous kind is met in the southern and central regions of Buryatia and Eastern Pribaikalie. It is a snake of medium and small size, with a long and thin body, a well marked neck, a small elongate head and a thin sharp at the end of the tail. There is a yellowish or orange spot on the back of the head. It doesn't have poisonous teeth. It inhabits coasts of reservoirs, bogs, thermal springs. It winters in holes and crevices. After wintering it appears at the end of Aprilbeginning of May, and in June-July it oviposits. Natural factors (short non-frost period, low birth rate, early summer frosts) as well as anthropogenic factors (cattle pasture, field works with a use of technics their capture by locals and tourists) influence on the grass-snakes' population. Secret Corners of Lake Baikal Box There is a remarkable abundance of ant hills (6-7,000 of them) on the Ushkany islands. They are not found in such numbers anywhere else in Russia. The biggest ant hills are 170 cm high and 310 cm across. 151 Wildlife sanctuaries In a wildlife sanctuary special protection rules do not apply to all natural species, as in a nature reserve, but only to particular species: the vegetation, or certain animal species, etc. Wildlife sanctuaries are created for various purposes: to restore and increase populations of animals that are hunted, to provide a rest zone for birds which are making their annual migration, to protect places where fish spawn, etc. Hunting, fishing and some other activities are not permitted in such areas. There are three state wildlife sanctuaries under federal control in the Republic of Buryatia – the Altacheysky, Kabansky, Frolikhinsky wildlife areas, – occupying more than 180,000 hectares in total. The Kabansky wildlife area is a part of the Baikal national biosphere park. There are also 17 wildlife areas in Buryatia under regional control. We will tell you about the two wildlife areas which are located near Lake Baikal. The Frolikhinsky Wildlife Sanctuary was established in 1976 in the north of Buryatia. It is a part of the central ecological zone of Lake Baikal and is also part of a World Natural Heritage site. The main landscape feature at the Frolikhinsky sanctuary is Lake Frolikha with its crystalclear glacial water. The landscape features here are both beautiful and romantically named: capes Ayaya, Frolikha, and Khaman-Kit, Papakha rock, and Frolikhinsky spring. The area is home to several large animals, including elk, wapiti, musk-deer, wild reindeer, bear, and wolverine as well as ermine, foxes and wolves. Some animals are under special protection: the otter, osprey, white-tailed sea eagle, black-hat groundhog, and one fish – the Frolikh char. The Frolikhinsky wildlife sanctuary and Lake Frolikha are very popular destinations for visitors. 152 Another wildlife area, the Enkhalooksky Sanctuary, is located in Kabansky District and was set up in 1995 to protect and restore populations of animals that are hunted along the coast of Lake Baikal, particularly the wapiti and elk. The area is home to elk, wapiti, wild boar, bear, white hare and many other animals that we already know. Birdlife includes the great bittern, gray crane, Caspian tern, eagle owl, and the white-backed woodpecker, all of which are registered in the Red Book of Buryatia. Secret Corners of Lake Baikal Box The origin of the place name “Enkhalooksky” is uncertain, but most specialists derive it from the word "Enkhe", which means "good fortune" in the Buryat language. The name of the Frolikhinsky wildlife area and of the river and lake, which are located there, is believed to derive from Frol, one of many Russian settlers who came to the shores of Baikal in the 17th and 18th centuries (a nearby cape is called after Frol). It is also possible that the name is connected to the char fish that are found in the Lake, since some old written sources call these fish “trout” (“forel” in Russian). 153 Natural monuments Dear friend! Lake Baikal Box has taught you a lot of new and interesting facts about the unique landscapes of Baikal's shoreline: its rocks, capes, islands, plants and animals. Some of them have become symbols of Baikal. As well as its parks and reserves, Baikal has a number of landscape features that are considered to be “natural landmarks” in their own right. The term “natural landmark” was first coined by the German scientist, Alexander Humboldt (he used it to refer to a particular tree of unique size and shape), but what exactly do we mean by a “natural landmarks”? Looking at the encyclopedia, we find: Natural monuments are natural objects that have scientific, historical, cultural and educational and aesthetic value (waterfalls, unique trees, etc., which are protected by the state). Scientists often disagree about the natural sites that deserve to be classed as monuments. They may be ancient trees, rocks, or islands. What natural monuments can we find on Baikal? There are the Ushkany islands, and many other unique and mysterious natural phenomena – trees on stilts, singing sands. So many that it is impossible to name them all! Mysteries of the Ushkany Islands The Ushkany Islands are unique (although they are from being the only unique islands on Lake Baikal) and objects of fascination to scientists and researchers on account of their mysterious origin, and unique flora and fauna. You already know that the Ushkany archipelago consists of four islands, and you probably remember where their strange name came from. Do hares have anything to do with the Islands' name? Tell your friends about it. The Ushkany Islands are 7 km to the west of the Svyatoy Nos peninsula, and their total area is 10 sq.km. Big Ushkany Island has a meteorological station and is part of the Trans-Baikal national park. Look carefully at the photo. What animal does this creation of nature remind you of? Round Island is closest of all to the Svyatoy Nos peninsula, and Long Island is (unsurprisingly) the longest in the archipelago (it is 1.25 km long). Bailal's greatest colony of gulls is to be found on the southern side of Long Island. What other creatures are found on the Ushkany Islands? There are about 2000 seals living on the western side of Thin Island, which is framed by a beautiful “necklace” of malachite (its bright green is visible in shallow water). Look attentively at the photo. What animal does this creation of nature remind of? 154 The “Singing sands” of Turali Turali, with its remarkable "singing sands", is one of the most visited places around Lake Baikal. The native people of the northeast shore of Baikal – the Evenks – knew of the singing sands long ago. The small cape of Turali was already marked on old maps of the Lake. On sandy beaches in a blustery wind and sometimes during a surf the sand makes a creaking sound, like new shoes or the touch of a bow on a violin string. There are many legends associated with "singing sands”: they have been interpreted as siren voices tempting travelers into the desert, or the ringing of bells in cities covered with sand. The explanation for “singing sands” remains mysterious and the sensation they arouse is uncanny – as if the earth began to sing beneath your feet. In fact, the sound is closer to a melodious whistle than to a song. Where else in the world can we find singing sands? The Stilted trees Peschanaya Bay (“Sandy” Bay) is a popular and picturesque spot. It is sometimes called the Siberian Riviera on account of its golden sandy beaches, cedar taiga and the emerald water of the Lake. Peschanaya is considered a natural monument due to its “stilted trees” – ancient larches that are bent in freakish form, and stand on natural stilts, that are taller than a man's height. The stilted trees are found on the northern slope of Sandy Bay, where water and wind constantly wash and blow soil away from under them, leaving the tree roots exposed. The Ininsky stone garden, to be found 15 km from the village of Suvo in the Barguzin valley, presents a spectacle of various and different-sized stones, which seems to have grown from under the ground. These boulders are up to 4–5 m in diameter. One researcher on Lake Baikal, Vladimir Lamakin, believes that these boulder heaps are glacial deposits, dating from over 100 000 years ago. Another explanation is that the stones were hurled into their present position by some natural cataclysm. 155 The word "turali" in the Evenk language means «rattling, singing sand». Children, to round off our story about nature reserves, here are some important rules that you MUST ALWAYS OBEY WHEN YOU VISIT SUCH PLACES: you can only visit reserves and protected natural areas with the permission of their administration; DO NOT: you must not dig holes to leave rubbish; you must not pick flowers; you must not damage trees and bushes; you must not cut your "autographs" on stones or trees or anything else; you must not gather plants, herbs or stones. 156 Peoples of Baikal More than 100 nationalities live in peace and harmony on the shores of Baikal, sharing the invaluable wealth of friendship between peoples. Now let's learn about how human settlers came to Baikal and its territories. Various tribes and nationalities have been living round Baikal since ancient times different. In the 3rd century B.C. the region was settled by the Kurykans, which were nomadic tribes of Turkic origin. Their livelihood depended on cattle breeding. The next to arrive were the Tungus or Evenk people, who lived in river valleys and specialized in hunting and reindeer breeding. Later Mongol-speaking tribes settled around Baikal. The Buryats had a semi-nomadic way of life. Russian settlers came to Baikal in the 17th century. Unlike the Buryats and Evenks, the Russians had a settled way of life: they cultivated the land, grew crops, made tools, and built towns and villages. Later arrivals include Tatars, immigrants from Belarus and Ukraine, and exiled Poles. 157 The Evenks The Evenks have lived in the taiga beyond Baikal since ancient times. The earliest records concerning the Evenks are in the works of Gmelin, Middendorf and Pallas, who refer to them as “Tungus”. One comment by these authors tells us that the Tungus are “obliging without servility, proud and courageous”. The traditional way of life of the Evenks was nomadic or semi-nomadic. They engaged in hunting, fishing and reindeer breeding, and also excelled in various crafts: forging metal, making implements out of the bone and hides of wild animals and reindeer, building sledges and skis, etc. They have a reputation as excellent forest hunters and pathfinders. The Evenks (the self-name – orochen, Tungus). 158 The Evenks dress differently in the summer and winter and for festive occasions, and there are marked differences between the clothes worn by men and women. “Their costumes are like the waistcoats of Spanish grandees” wrote the exiled Decembrist, Wilhelm Kuechelbeker, who was delighted by the Evenks and called them “Siberian aristocrats”. The Evenks are still well-established in their traditional territories, which cover almost the whole of Eastern Siberia. National dishes of the Evenks include silavun (the meat of a wild animal or fish, fried on a spit), kulnin (dried meat dipped in flour and boiled in water with berries) and seven (bear meet crumbled into small pieces and fried in bear fat). Secret Corners of Lake Baikal Box The Evenks lived in tent dwellings (“chumy”), covered with birch bark in the summer and deer skins in winter. These shelters give excellent protection from frost and the north wind, and can be erected in less than twenty minutes! 159 The Buryats The Buryats are a native people of Eastern Siberia who have inhabited the area that is now the Republic of Buryatia, Irkutsk Region and Zabaykalsky Territory for many centuries. The Buryat tribes are first mentioned in the Sacred Legend, a renowned Mongolian chronicle of the early 13th century. The Buryats who settled around Baikal chose a way of live that suited their surroundings. Their skills included hunting and fishing, and later farming the land. The Buryats excel particularly in cattle breeding. Under Russian rule the Buryat groups and tribes came together to form a distinct community – the Buryat ethnic group – by the end of the 19th century. But several separate Buryat clans can still be recognized: the Bulagaty, Ekhirity, Hori, Hongodory, etc. Secret Corners of Lake Baikal Box Various legends have survived about the emergence of the Buryat tribes. The Buryats connect their origin with particular animals and birds. The Hori Buryaty tribe, for example is supposedly descended from a divine swan-girl who had to marry the sharp-witted Horidoy, after he stole her swan clothes when she was bathing. She bore him 11 sons who were the ancestors of the Hori Buryats, but then tricked her husband, took back her swan clothes and left her family, saying:“You, earth dwellers, stay here, and I will fly to my homeland in the skies!”. 160 The traditional dwelling of the Buryats is the yurt. A yurt can be made of felt, and also of logs or planks. The dome-shaped ceiling stands on four columns and has a hole to give light and allow smoke to escape from the central fire place. The entrance to the yurt is on its southern side. The interior of the yurt is divided into two parts: for men (on the left) and for women (on the right). A decorated post for tethering horses stands in front of the yurt. Surkharban is a buryat sport holiday. Its old name is “Eryn gurban naadan” (“Three games of men”). Necessary competitions in three kinds of sport take place at the holiday – archery, horse racing and wrestling. During the holiday a famous dance called Yokhor is danced. The holiday of White Month or Sagaalgan goes back to the ancient national and religious traditions of Mongolian peoples. It’s a symbol of man’s and nature’s renewal, openness and purity of thoughts, hope and good expectations. The name of the holiday comes from the word “sagaan” which means “white”. Earlier “White Month” was considered to be a holiday of dairy products and was celebrated in autumn. Nowadays the holiday of White Month is celebrated as the New Year according to the lunar calendar. The best known Buryat dish is buuzy, which is steamed in a way similar to the Central Asian manty. Other traditional foods are milk and dairy products: salamat and urme, which are made from beaten milk, as well as sour milk, and dried pressed curds (huruud) which cattlefarmers ate instead of bread. 161 The Russians The first Russians who came to Baikal were Cossacks, sent there by order of the Tsar to settle this part of Siberia. They engaged in farming and cattle breeding, crafts, hunting and fishing. They brought their own folk culture with them to the new place of settlement, but also enriched it with new Siberian cultural elements, learning to build houses that can withstand the bitter Siberian cold and to grow bread, wheat and other crop types. Later, more Russians came to Baikal from many different regions, particularly after the emancipation of the serfs, when development of these virgin lands offered great opportunities. The Old Believers are a particularly interesting part of the Russian community around Baikal. 162 The Old Believers came into existence as a result of the schism that accompanied Russian church reforms in the 17th century, and migrated to Siberia in order to escape persecution. The Old Believers had large families (hence their other name, “Semeiskiye”, which means “family people”) with as many as 10 or 20 children. They grew wheat, kept cattle and were the first in Siberia to grow vegetables. The Old Believers of Trans-Baikal are still unique in maintaining a traditional Russian way of life that has been lost elsewhere. The “Semeiskiye” are respected for their devotion to hard work, strict observance of old customs and adherence to different rules, which helped them to survive in the Siberian climate. They observe high moral standards: not to abuse alcohol or to smoke, and to maintain a strong commitment to the family. These habits have ensured good health and long life in their community. Secret Corners of Lake Baikal Box Descendants of the Trans-Baikal Old Believers live today in the Republic of Buryatia (Bichursky, Zaigraevsky, Mukhorshibirsky and Tarbagataisky Districts), also a number of villages: Novo Desyatnitskoe village (Kyakhtinsky District), Yagodnoe village (Selenginsky District), Hasurta village (Horinsky District), Leonovka and Voznesenovka villages (Kizhinginsky District), and in the cities of UlanUde and Gusinoozersk. Many Old Believers also live in Krasnochikoysky District, which is part of Trans-Baikal Region. 163 Ecological traditions and customs of the Buryat Peoples Ecological traditions are the sum of national knowledge and skills gained in the process of human interaction with the natural surroundings, formed under the influence of culture, standards, ideals and stereotypes of thought, which are transmitted from generation to generation. “Ecological traditions” can be in the nature of recommendations or absolute prohibitions concerning human action in the environment. The first call on us to avoid disturbing mother-earth without any need: not to damage and dig into the earth, except on arable land and at farmsteads, or the recommendation to use dead wood and not live wood for making fires. There are also many prohibitions: not to pour water on a forest path, to cut down trees near settlements, to cut pine, fir or cedar trees, and to kill certain animal species. Boys and girls, let's make a checklist of the ecological principles, which are applied by the people living around Lake Baikal. This is very important because national beliefs, customs, traditions have always been used for the protection of nature. Then you can tell your friends and visitors to Baikal all about them. Since ancient times all peoples have respected five natural elements: water, fire, land, air, wood. Water All peoples have treated water with care since ancient times. Water was honored as a pure element. In old Russia water was a means of purification and at the same time a source of power. People organized their merrymaking and fortune-telling near water. The religious attitude to water among the Buryat people is connected with belief in a water spirit, called "Lusaday Khan." Remind your friends that people should not profane water, do their laundry or wash cars in reservoirs. Earth Many peoples call the earth the great provider. In ancient times it was considered a terrible sin to move stones, to dig and damage the earth's surface without any need, and to spill cow's or mare's milk on the earth. A person who cleans roads is considered to be a benefactor, and he also clears the path through life path for his descendants. So it is always a good deed to clear obstacles from a road. When you cultivate the land you should not leave stakes and tools in the ground when they are not longer necessary, because they are like splinters in a finger. When tubers and roots of plants have been dug out, the ground should be leveled and not left uneven. 164 Fire Fire is a symbol of life and was respected as one of the most formidable forces of nature for both good and evil. Fire must be clean: you should not step over it or throw garbage into it. The sun is the sky's fire and the home hearth is the earth's fire, so it should be treated with respect. Ancient people believed that flames were alive and needed food and drink. It is good to give a present to the fire spirit, splashing fresh tea and throwing meat slices into the fire. Air Air is the basic element of life. Every living being needs it. All peoples consider it sinful to pollute the air in holy places with smoke. The Buryats clean the air with a special aroma, which they call “Sanzei” (Bogorodskaya dried grass, or “Aya-ganga” in the Buryat language), and Russians use incense (an aromatic substance that includes the juice and pitch of different plants) Wood There is a strong cult of respect and worship for wood among many peoples. The oak was sacred to the Slavs, who viewed it as the “world tree” and as the essence of maleness, while a birch tree was close to femininity. The Slavs planted an oak if a boy was born and a birch or a pine for the birth of a girl. The Buryats believed that by cutting down a tree without reason you would shorten your own life and that of your descendants. It was forbidden to cut down trees without need, and to cut down a tree that stood alone was particularly sinful. Boys and girls, you shouldn't break branches or scrape the bark from a tree, because it is a living being and feels pain like we do. 165 Secret Corners of Lake Baikal Box There is a superstition that if you want to come back to Lake Baikal you should throw a coin into the water. This will symbolize that you have treated the Lake well, pacified it, and showed your respect, so the Lake will not prevent you from coming back. Another belief connected with water was that fertile rain could be brought on by clearing springs and wells, and deepening the channels of streams. Light rain could be encouraged by throwing grain into a well and for heavy rain people threw peas. Children in Buryat families were taught to respect the land. Damaging and desecrating the environment could merit punishment as serious as the death penalty. Even socks in Buryat boots (called “gutuls”) were turned upwards to avoid stumbling and offending the ground. According to ancient beliefs, the forest has two owners: Borovoi and Grandfather Woodsman, who keep a strict guard over the forest. Anyone who injures the forest will be punished, as the forest guards will call their friends, “Manila” and “Uvodila”, to help punish the malefactor. There is a tradition in Buryatia of decorating the branches of certain trees with ribbons and scraps of new fabric. A tree that stands alone in the steppe is also sacred, and passers-by should stop and make a ritual offering of food, coins, or coloured fabric. 166 Ecological problems of Baikal Dear children, we have come to the end of our journey across Baikal. Now you know that we live in one of the most remarkable places on earth, on the shore of the deepest, the most ancient and one of the most beautiful lakes in the world. But, unfortunately, not everybody treats it properly and shows due respect towards the natural environment. In this part we will tell you about ecological problems of the Lake and of the landscapes and habitats around it. We hope that you will then be among those who are ready to protect the unique natural wonder, which is Lake Baikal. “Ecology” is a word from Ancient Greek, meaning “the science concerning home or dwelling place”. It studies all the complex interrelations in nature, the interactions between living organisms and non-living matter. The term was first coined by a German scientist, Ernst Haeckel, in 1866. The Ecological problems of Lake Baikal arise mainly from human activity and particularly from the operations of industrial enterprises along its shoreline and in its drainage basin. A drainage basin is the zone from which rivers, lakes or seas collect their water: it includes underground water sources, streams, and ponds from which water gathers, flows and falls into a river, and then into a lake or sea. It includes also the natural area from which water flows down to rivers and lakes after rain. Quality of the lake water also depends on agriculture: waste from animal husbandry, and soil erosion. 167 Human activity on the shores of Lake Baikal Human beings have not always caused harm to the Lake. The difficulties have arisen gradually. We can separate the recent history of human activity on Lake Baikal into several stages. The first stage is the end of the 19th and start of the 20th centuries, which was a time of discovery and application of new scientific inventions, and improving technology: universal application of steam engines, invention of cars, electricity, and the construction of railways, including the rail link from Moscow to the coast of the Pacific Ocean, one part of which was laid along the shore of Lake Baikal. The second stage dates from the 1930s, when there was rapid development of forestry and wood processing. Forests on the slopes of mountain ranges around Lake Baikal were felled and timber was floated down rivers and over the Lake. Some of the timber sank and decayed at the bottom of rivers, polluting them and reducing the populations of some fishes and animals: black and white grayling, taimen, otters and other species that can only live in clean water. Different types of wood were floated down rivers: pine, birch and larch. The larch often sank. The third stage began in 1959 when work started on a hydroelectric power station on the Angara River, as a result of which the water level in Lake Baikal rose by one meter. The shore territory along the east coast of the lake was flooded, the area of bogs increased, and populations of some fish, which were important for fisheries, declined due to decline in numbers of crustaceans (particularly epischuras) in the Lake. 168 The fourth stage was in the 1960s-80s when the Baikal Pulp and Paper Plant (BPPP) was built at the southern end of the Lake and the BaikalAmur Railway (BAM) was built around its northern shores, disturbing the Lake's ecosystem. The fifth stage, which dates from the 1990s, has seen large-scale poaching both on the lake itself and in the surrounding forest, involving illegal catches of valuable fish species (omul, and sturgeon) as well as hunting for fur animals (sable, fox, and seal). Boys and girls, unbridled human activity causes huge damage to the environment. Deforestation, fires, uncontrolled ploughing, and uprooting of forests have led to wind and water erosion. As a result, more than 10 species of birds that live around Baikal (whooper swan, tundra swan, gray goose, shelduck, etc.) have ceased to nest, and their numbers have declined sharply. Various plants and animals, which are biological pollutants, have also appeared: Canadian pondweed, the Amur catfish, the Amur sleeper, and many others. Erosion (”corrosion” in Latin) - corrosion of rocks and soils by surface water floods and winds. It includes a break and carrying out of material wreckage and their further measures. Define, what kinds of erosion are represented in the pictures. Explain, why it happens in nature. Do you think it’s possible to prevent it? 169 Water and air pollution The principal pollutant of Baikal is the Baikal Pulp and Paper Plant (BPPP) which dumps its foul water directly into the Lake and emits pungent, suffocating gas and vapors from cooked pulp, polluting the air and river tributaries running into Baikal. Many people ask: “Why was this plant built on the shore of Baikal? Is it impossible to produce paper, cardboard and pulp somewhere else?” Children, you know that the water in the Lake is so pure that it is close to the quality of distilled water. Such water is needed for pulp processing, which is why the BPPP was built on Baikal in 1966. The cellulose made at the plant is used for production of special aircraft tires, and also to make carbon for the defense industry, which can withstand temperatures of several thousand degrees. The forests around Baikal provide raw material for the plant. Imagine how many trees are cut down to feed the plant! Another plant produces cardboard and paper on the banks of the Selenga River (the Selenginsky Pulp and Paper Plant), but it uses a closed production cycle, which prevents direct discharge of foul water into the river. 170 Another major source of water pollution in Baikal is the Selenga River, the largest inflow to the Lake. The river delta is a center for migratory birds and the main spawning place for the Baikal omul. The main pollutants of the Selenga River are large industrial enterprises on the territory of the Republic of Buryatia. Sewage treatment plants account for 35% of foul water flows into the Selenga. Enterprises in Trans-Baikal region also create pollution: the town of Petrovsk-Zabaykalsky and the village of Krasny Chikoy are located on the Chikoy and Hilok rivers, which are the main tributaries of the Selenga river. The Selenga River has its source in Mongolia, and the river also takes in pollutants in that country (created by industrial and mining plants, and by agriculture). Other pollution of Baikal water comes from industrial facilities in Russian cities and towns nearly the Lake, including Irkutsk, Angarsk, Cheremkhovo and UsolyeSibirskoye. The Irkutsk hydroelectric power station, shipping on Baikal, and the Trans-Siberian Railway have negative impacts on water level in the Lake. 171 SOS! Fire! The greatest threat to the forest around Baikal is from fires, which are particularly destructive for coniferous forest, since it takes longer to restore. Fires are usually caused by people who fail to put out a camp fire or throw down a burning match or cigarette. Very rarely fires are started by lightning. Fire destroys the habitat of birds and insects and its aftermath is a ”green desert” of deforested land covered by shrubs and grass. Until the taiga is restored, only poor-quality species of wood will grow. What would happen if the Lake did not have forests around it? Rains water would wash earth down into the Lake in a dirty avalanche, the rivers and streams feeding the lake would dry up, and Baikal would turn into a big, dirty reservoir. e se Remember th ! simple rules , or use ng a campfire ti ar st re fo e b the space Carefully clear fire. f an old camp o ts when the an n m re the s, especially e e tr r e d n u campfire und.

You have probably seen yourself how much garbage people leave behind –glass and plastic bottles, plastic bags, tins, etc. Thousands of people come to the Lake shore every day, so you can imagine how much waste accumulates. Paper takes only 15 days to break down in earth, but a can takes 20 years, and plastic does not decompose at all. What must you do to reduce the quantity of garbage left around the Lake?

I am an ecologist! Dear boys and girls, garbage is one of the main ecological problems for Baikal today. We ask you to discuss this very important topic in your classroom, and to carry out some experiments. Questions for discussion: What will archeologists of the future be able to learn about our civilization from investigating our garbage heaps? What is the difference between waste and garbage? What can be reused? What can be recycled? What are the difficulties in processing garbage? What resources can be saved by recycling of waste? How can garbage be processed and what are the most efficient ways of processing it? What do you and your relatives do with garbage? Glass is one of types of garbage. What can we do with empty glass bottles? What can be made from glass? Why is glass a suitable raw for cookware production? What are advantages and disadvantages of things made of plastic? Plastic is the type of garbage that takes longest to decompose. What do you think what plastic is made of? Why is plastic used to make certain things? What are advantages and disadvantages of things made of plastic? Experiment №1. "The impact of heat on plastic" Experiment №2. “Does plastic decompose? “ Tools and materials: a hand-dryer with a clamp or vise, a pair of tweezers, different things made of plastic (spoons, containers from food), and a stopwatch. Work process: dig various plastic bags into the ground, and nearby dig in the same amount of bags made from paper. Topic issue: How does heat influence plastic? Work process: using tweezers, you can hold one of plastic things under the stream of hot air coming from the hair dryer. Write it down what you have noticed. Try to do the same in turns with other things with a help of tweezers. Questions for self-checkup: What do you think what will happen to the paper and plastic bags? In a few weeks time dig the bags out of the ground. Compare your hypothesis with the actual result. Do you think plastic can be recycled? What things can be made from recycled plastic? What did this experience help you to learn about plastic and its production? 174 I am an ecologist! Project: Pines and Needles Baikal's shores are surrounded by green. People often go to the forest to admire its beauty, breathe the fresh air and to listen to the silence. But not everyone knows which tree species make up Baikal's green necklace. Find the odd-one-out in the following list. Indeed, these plants have a feature, by which you can select two “odd” species. Find them. Pine, fir, cedar, Siberian dwarf-pine, larch, Siberian spruce Why exactly them? The trees that you have selected belong to coniferous species. They differ from other plants because: – Coniferous trees have needle leaves; – Coniferous trees are also called “evergreen”; – Coniferous trees have cones. STAGE 1 OF THE PROJECT: multi-coloured reading Read the text to learn about those coniferous trees which grow on the shore of Baikal. Use colour pencils to shade them: – for the tree’s crown – for cones – for needles – for growth conditions 175 Project: Pines and Needles. Use these data to fill in the comparative table Name of plants Crown shape Cone features Needle features Common Pine Siberian pine Siberian spruce Fir Cedar Siberian Larch 176 Growth condition Importance in nature and for people The Siberian spruce The Siberian spruce is a slim evergreen tree, which grows as high as 50m, with trunk diameter up to 2m. Unlike the pine, the spruce has a cone-shaped crown. Spruce needles are small (about 1.5 cm long) and do not form bunches, but stay separate, forming a thick covering. The needles have a life of 6 or 7 years. A Siberian spruce has long beautiful cones, about 10-12 cm tall. A young spruce has a dense, often narrow top, while older trees usually have a wide and spreading top. A spruce forest is dark, quiet and damp, with little light and few insects. The spruce can also be used to build houses, as well as for making pulp and paper, essential oils, and even ascorbic acid. Some stringed musical instruments are made from spruce wood. The life-cycle of the Pallas' warbler, the smallest bird in Buryatia, is closely connected with the tree. This shy bird, weighing just 3-7 grams, builds its nest at the base of spruce branches making it almost impossible to see and to approach. The Siberian larch A larch is one of few coniferous species that shed their needles during the winter, thereby retaining moisture, which it badly needs in the winter months. In the springtime the long, thin branches of the larch are covered with needles that look like soft, green brushes. In autumn larch forests flash with a golden light, and the queen of the Siberian forest sheds her raiment at the first frosts. Winged seeds fly out of the ripe cones at the same time. Larch has been valued as excellent ship-building wood since earliest times, and larch forests were called “ship groves”. Its high concentration of resin protects larch wood from rot, and the timber may last for hundreds and even thousands of years. The larch lives for about 400500 years and withstands cold winters, so it can be seen even far beyond the Arctic circle. The tree can also resist southern heat and drought. The larch is fond of light, and therefore has an open crown that allows light to penetrate. Straight-growing larches can grow into forest giants with height of 40–45m and a trunk diameter greater than 1,5 m. 177 The Fir The fir looks very like the spruce; having the same dense, conical and feather-edged crown. The two trees can be easily confused at a distance, but are easily distinguishable close up. Fir needles are rather different from those of the spruce, being flat with a rounded top. There are two waxy white lines on the bottom side of each needle and the upper side of the needles is a monotone dark green with a glossy surface. Fir needles are arranged on the branches one by one like spruce needles, but they live longer (up to 10–12 years) and are soft to the touch. Fir cones point upwards like candles on a Christmas tree. The trunk is covered by a light gray, smooth bark but older trees often have some splits in their bark. The trunk itself is very slender and straight. Fir trees like shadow, so it is always very dark in a fir forest. The tree resists cold, but it requires humidity, so firs will only grow where the level of air humidity is high enough. The fir is very particular about its soil and will not grow on poor sandy soil and in bogs. Fir wood is soft, weak, and rots easily. It is used in the perfumery industry because it contains special aromatic substances that can be used to produce perfume and soap and which are not found in the needles of other trees. The Common pine The common pine is a slim, evergreen tree, which grows as high as 40 m. Pines seek light, so the bottom branches usually die off and the trunk becomes a slender column pointing up to the sky. The pine has a mastlike crown. Pine forests are always light and it is possible to see a long way through the forest. Pine needles form bunches of two needles each. Pines are not particular about their soil quality, which may be dry or boggy. Pines that grow on sandy soil send down deep roots to find water, so they stand up well to high winds. The pine is a very useful tree for people. It can be used to build houses, and pine wood is naturally rich in resin, which prevents rot. Pine resin also has many medicinal properties. Pine needles are used for the production of pine extract for baths, essential oils, and also to make a special paste for the treatment of burns and swellings. 178 The Cedar pine The cedar pine is a powerful tree with a dark green crown and long,barbed needles. It grows to about 35–40 meters, has diameter up to 1.8 meters, and its needles are about 6–14 cm long. The needles are three-sided, and gather in bunches of 5. Cedar wood has a beautiful texture and a pleasant pink colour. A grand piano made of cedar is graceful and sonorous, containers made of cedar are excellent for keeping milk products fresh, the wood is used to make containers for oil, a wardrobe made of cedar will keep moths out, and a beehive of cedar is well-liked by bees. Cedar wood resists rot and can be easily cut, so it is much used in wooden architecture, and also for making pencils. Families can live in houses made of cedar pine for many generations, and the wood is excellent for building bath houses, saunas and for making barrels. Hunters in the taiga will often spent the night under a cedar because of its warmth. The tree's soft resin cures toothache and gum disease, and can also heal cuts and burns. Cedar needles can be used for aromatic baths. The cedar nut is particularly valuable and can be used to make cedar oil, cedar milk and cedar cream. Under natural conditions, in the taiga, a cedar pine starts to produce nuts when it is 40-50 years old. A bird, the nutcracker, depends on the cedar pine, and also helps the tree to propagate, by pecking at the pine nuts and hiding them in the woodland floor. In two months the bird can store up to 60 kg of nuts in 20,000 different places. The bird feeds off the nuts in the winter and uses them to feed its young, and some of the remaining nuts sprout into new trees. Cedars can live for 300–600 years. The Siberian dwarf-pine The Siberian dwarf-pine, which can be seen in the forest around Baikal, is a thickly branched, low-lying evergreen bush. It has three-sided needles, 4–7 cm long and gathered in bunches of 5. The cones are oval or oblong, 4 cm long, of a bright, light-brown colour. The edible seeds are about 7–10 mm long and are spread by the nutcracker bird. The bushes are a favourite refuge for sables, squirrels, bears and other animals. The wood and the needles can be used as fuel, and also to extract turpentine, resins and essential oils. A water infusion of the needles is a good remedy against scurvy and the seeds contain nut oil. The Siberian dwarf-pine cedar is grown as a decorative plant in gardens and parks. 179 Stage 2 of the project: growing cedar trees” Plan of Action To grow up a Siberian cedar pine you need seeds ( pine nuts) 1.Make the seeds germinate Put the seeds into a container with water. Seeds of good quality will swell up and sink to the bottom. Empty husks and seeds of bad quality will float, and you should throw them away. 2. Protecting against infection To prevent seed diseases you should pre-treat the seeds by keeping them for 2 hours in a 0.5% solution of potassium permanganate. 3. Soaking Pour hot water (40-50 C) onto the pine nuts and soak them for three days, changing the water each day. Then mix the nuts with three times their volume of peat or medium-grained, well-washed river sand. The sand or peat should be damp, but not too damp. 4. Stratification The best time for planting cedar is the end of April and beginning of May. 90 days before planting the nuts should be “stratified”. This is done by pouring the mix of seeds and peat or sand in a wooden box to a depth of 10-20 cm. Then, make holes in the walls of the box and under the box to allow air to enter. Mix the contents of box once every 15 days and ensure that they remain as damp as when first mixed. The box should be kept at a temperature of + 4-6 C in a basement, cellar, or home refrigerator. It is important that the seeds remain damp at all times. The temperature can fall as low as –4 C, but only for 2-3 days. If the stratification is done correctly, most of the seeds will produce sprouts when they are sown. 5. Sowing the seeds in the ground The best soils for the cedar are sub-sands (not too dry) or loam soils (not too wet). The seeds should be sown at a depth of 2 - 3 cm. The sowing should be “mulched”, which means covering it with a layer of sawdust and peat crumbs. This prevents the soil from drying out, and from solidifying after watering or rain, and also stops weeds from growing. 6. Make the seeds germinate Watch how sprouts emerge 7. Make the seeds germinate Taking care of the young tree It is interesting to observe how the cedar sprout rises. First of all, there is a green loop. Then the sprout becomes straight and puts the nutshell out of the ground, so that it looks like a cap on the top of the stem. Little by little an emerald whisk of needles opens, and the nut falls off. You should care for the growing cedar by weeding, loosening soil and watering. The best way to improve the soil is with cow manure (mixed with water), but you can also use combined mineral fertilizers. The cedar grows slowly for the first 5-6 years, but then much faster and there is not long to wait for the first harvest of pine nuts. 180 Stage 3 of the project: measuring air pollution by the state of pine needles Do you know that: Coniferous trees are particularly sensitive to air pollution. You can easily measure the degree of air pollution based on the condition of pine trees. Monitoring plan: 1. Select several trees that are a little higher than a person. You can define the age of a tree by counting whorls (points from which a circle of branches emerge) on the trunk. 2. Look at the top sprouts from the previous year (the second whorl from the top) and examine the state of the needles to define the level of damage and drying-up. 3. Define the degree of damage according to the following features: 1 – Needles without visible damage; 2 – Some small spots on needles; 3 – Many spots on needles, some of them large. 4. Classify degrees of drying as follows: 1 – There are no dry areas on the needles. 2 – The tip of the needle is dried (2-5 mm). 3 – The needle is dried for up to 1/3 of its length. 4 – The needle is dried for more than a half of its length. 5. The age of the needles should be taken into account. To do this, count the share of needles that are still present (e.g. 10%, 30% or 50%) on each whorl. Then you can work out the age of needles by comparing the number of areas on a sprout that have completely preserved needles with the areas of partially preserved needles on the previous sprout. 6. Do a quick test to measure the level of air pollution: Maximum age of needles The degree of needles damage on two-years old sprouts 1 2 3 4 years I I–II III 3 years I II III–IV 2 years II III IV 2 years – IV IV–V 1 year – IV V–VI 1 year – – VI Nominal designation of the air pollution degree: I – perfectly clean IV – polluted ("cause of concern") II – clean V – dirty ("dangerous") III – fairly clean ("normal") VI – very dirty ("highly dangerous") 181 We are playing!

CONTENTS OF PART 5 The first reports of Baikal 190 European researchers of Baikal (18th and 19th centuries) 192 Native scientists 197 Chronology of Baikal research 199 MIR Submersibles on Baikal 201 Underwater ecosystem of Baikal 203 Baikal in figures 210 Topology of the Baikal coast 214 Baikal legends and fairy tales 217 Our love for Baikal: Poems about the Lake 227 Bibliography and recommended literature 230 The first reports of Baikal The oldest surviving references to Baikal ("Bejhaj") are in Chinese chronicles dating from 110 BC. In The Secret Tale of the Mongols (12th–13th centuries) Baikal is called "Bajgal-Dalaj". European travellers who made their way across Siberia to China in the 12th-13th centuries called it a “lakesea”. There is a detailed description of Baikal and its coast in the notes made by Russian Cossack explorers from the western Russian provinces. A Cossack brigade of 74 people sailed in 1643 on wooden boats along the western shore of the lake as far as Olkhon Island under the leadership of Ataman (Cossack captain) Kurbat Ivanov. Ivanov drew the first map of Baikal, “Sketch of Baikal and the Rivers that flow into it”, which was highly important for further exploration of the territory around the Lake. Later a group of Cossacks led by Maxim Perfilyev journeyed along the east coast of Baikal and created a number of fortified settlements, the largest of which was Barguzin. One settlement on the east coast of Baikal was named Maksimikha after the Ataman. A group of Cossacks accompanying the diplomatic mission of Erofei Zabolotsky, an envoy sent by the Tsar to make a treaty of peace with the Mongolian khan, perished in a skirmish with local people. The Posolsky (“Envoy's”) Monastery still stands at the place of Zabolotsky's death. the Posolsky monastery 190 In 1665 the Archpriest Avvakum crossed Baikal, which he called the "ocean-sea" and described it in his book, Life of Archpriest Avvakum. Conerning the Lake's fauna he wrote: “There are many birds, geese and swans, which settle on the sea, like snow. The fish in the lake are sturgeon and taimen, sterlets, omuls and white-fish and many other kinds. The water is fresh, and there are a lot of seals in it, in this huge oceansea. Living in Mezen, I have never seen anything like it. The fish are very fat, so they cannot be fried on a pan, as it will spill over.” Nikola (Nikolay Gavrilovich) Milesku Spafary (1636–1707), a Russian diplomat of Romanian origin, who was also a scholar knowing several languages, led a Russian embassy to China from 1675 to 1678. On the way to China, in his travel diary, he gave the first description of Baikal for geographical science: “Baikal can be called a sea because … to go round it is impossible... its size at length and width is great … and its depth is great. And it can be called a lake because its water is fresh and not salty; the water is very pure, so that the bottom can be seen at a depth of many sazhens, and it is good to drink.” Spafary also listed all the rivers running into Baikal, and particularly the rivers Selenga, Barguzin, and Upper Angara. He also described Olkhon Island. He later published the book in Russian as A Journey through Siberia to the borders of China. (from Baikal in Questions and Answers. G.I. Galaziy, Irkutsk, 2004) 191 European researchers(18th-19th centuries) The works of European researchers of Baikal have a special place in the history of Russian science. Study expeditions by Russian and foreign scientists and naturalists, cartographers, botanists and naturalists, mineralogists, ethnographers and historians reflected the ideas of the Russian enlightenment scholar, Michael Vasilievich Lomonosov, of the importance of understanding the natural environment and vast resources of Siberia. Travellers and researchers who visited Siberia in the 18th century included foreign diplomats, Swedish officer-prisoners of war, and the members of academic expeditions organized by Peter I and his successors. The Englishman John Perry who worked in the Russian diplomatic service published a book in London, The State of Russia under the Present Czar, which contains a description of the natives of Siberia – the Tungus (Buryats). The diplomat John Bell travelled by land to China and, in his twovolume Notes (1719–1720), described in detail the history of the Russian conquest of Siberia, the cities of Tobolsk and Irkutsk, the life, clothes and religion of the Buryats, and their language: “They are a numerous people extending to the east and the south from Lake Baikal, very fair and sincere”. John Bell's books were translated from French into Russian in 1776. A Swedish officer, who was taken prisoner at the Battle of Poltava, the nobleman Phillip Johann Stralenberg remained in Siberia for 13 years. On the instructions of the academician Daniel Gotlib Messershmidt he collected materials for a map of Siberia and a review of its history. When he returned home he published a book, The Northern and Eastern part of Europe and Asia (1730). 192 Daniel Gotlib Messershmidt was one of the first participants of German expeditions to Baikal. He spent many years in Siberia (1720 - 1727) and collected a large quantity (10 volumes) of naturalist, ethnographic and cartographic materials. Messershmidt's report, Review of Siberia or Three Tables of the Simple Kingdoms of Nature was not published, but his materials were widely used by later researchers. The archives of the Russian Academy of Science in Petersburg. Unknown painter who took a part in the expedition of D.G.Messerschmidt. Johann Gmelin wrote a four-volume work, The Flora of Siberia, describing 1778 kinds of plants, most of which were a new discovery for the world of science, and amassed a rare collection of minerals. In his diary Travels across Siberia (four volumes, Goettingen, 1751-1752) he described Siberian fortified settlements, fairs in Tomsk and Kyakhta, ways of life and religious beliefs of the local people. A portrait of Johann Jacob Haid the middle of XVIII century. Mezzo-tinto. 29x18 cm. S-Petersburg., the archives of Academy of Science Peter Simon Pallas lived in Siberia for 26 years and his written works extend to 30 volumes. A five-volume account of the flora of Russia contains the description of 6522 plants. Pallas was one of the first European researchers to describe the Lake Baikal endemic – the Baikal oilfish. Pallas explored the areas between Irkutsk and the borders of Mongolia, recording geographical, biological, and geological facts as well as valuable ethnographic data about the Buryats and Mongols, their religion, way of life, and employments. He visited the settlements of Udinsky and Selenginsky, and the “datsans” (Buddhist settlements) of Gusinoozersky and Tsongolsky . Pallas was one of the first researchers to note the probable identity of the Buryats and the Huns – his suppositions were proved true many years later by archeological finds in Buryatia and Mongolia (the remains of Hun settlements around Ulan-Ude). 193 The St.Petersburg academician, botanist, professor of mineralogy, and ethnographer, Johann Gottlieb George spent many years near Baikal, in Tomsk, Irkutsk and Kyakhta, made a map of the lake and its surroundings, described more than 730 plant varieties in Baikal region, and made a considerable contribution to ornithology, describing more than 60 types of birds. Gerhard Friedrikh Miller studied Baikal region together with Gmelin. Miller carried out field research and collected a huge amount of material on the folklore of the Russians and native peoples of the region, and also on archeology and ethnography. His works, Description of the Siberian Kingdom (1750) and History of Siberia were published in St. Petersburg, and republished in Moscow and Leningrad in 1940–41. In 1820 an English sea captain John Cochrane made a journey across Siberia and Kamchatka with the permission of the Russian government, which he described in a book published in 1824-25 in London, A Pedestrian Journey through Russia and Siberian Tartary, which includes an account of the beauty of Lake Baikal. The renowned Finnish linguist and ethnographer Matias Alexander Kastren travelled to Buryatia in 1848, where he studied the Buryat-Mongolian language, family life and social conditions, and Buryat clothing (not merely its appearance but also its significance in Buryat social life). The French researcher Paul Labbe published a book in 1909, The Siberian Lamas, acquainting European readers with the religion of the Buryats the nature of the region, its plant and animal life, daily life, customs and wedding ceremonies of the Russians, Buryats and Cossacks. Various Buryat clans are described in the book, and also the work of the Selenga Steppe Duma (a native parliament). 194 Benedict Dybovsky (1833–1930), a Polish-Russian scientist, geographer, zoologist, physician and linguist, and a corresponding member of the Academy of Sciences of the USSR did much work to improve knowledge of Siberia and the Far East of Russia. Dybovsky studied at the universities of Derpt, Berlin, Breslau and completed a thesis for the Degree of Doctor of Medicine and Surgery. He was sentenced to death for his part in the Polish revolt of 1863-1864, but the sentence was commuted to 12 years of Siberian penal servitude. He was first deported to Chita region and then to the village of Kultuk in Irkutsk Province. Dybovsky carried out research on Baikal with Victor Aleksandrovich Godlevsky. His classic study of the Lake's microfauna (more than 100 kinds of freshwater shrimps and 2 varieties of the deep-water Baikal endemic, the oilfish) represent the beginning of systematic study of the world of Baikal. Victor Aleksandrovich Godlevsky (1831–1900) was a Polish zoologist and scientist who was exiled to Baikal in 1865 for his part in the Polish revolt. Together with Dybovsky he moved to Irkutsk in 1867 and for more than 10 years the scientists worked together studying the Lake, its depth, the water temperature at different depths, species structure and variety, and biological features of the fauna of Baikal. The work was mainly carried out in wintertime, when all parts of Baikal could be reached across the ice. Dybovsky himself said that the success of their scientific research was due in large part to the technical abilities and physical endurance of Victor Godlevsky. Godlevsky's remarks on the natural wealth of Baikal deserved to be cited: “The wealth of lower-order animals to be found in Baikal is quite remarkable, in terms of both the number of species and the number of individuals. The bed of Baikal teems with life that cannot be found in southern seas: it is sufficient to turn a few stones along the shore to enrich systematic zoology with new species.” Together with Dybovsky he studied about 200 bird species and discovered one species that was absolutely new to science – the four-toed Siberian salamander. A number of animals have been named after Godlevsky, including Godlevsky's bunting – a bird which is now registered in the Red Book of Buryatia. 195 Ivan Dementevich Chersky (1845-1892) studied geology, paleontology, and tectonic processes inside the earth's crust. Chersky carried out a geological study of the Baikal shore and compiled a detailed geological map, studied the Siberian post route from Lake Baikal to the eastern slopes of the Ural Mountains, and also presented a Description of Collections of Tertiary Mammals Collected by the New Siberian Expedition. Applying his skills as a a geographer, Chersky studied the streams and rivers flowing into Baikal; as a geomorphologist he proposed the division of Siberia into a Western and Eastern part; and as a biologist he gave an account of the pink seagull. One of the tools that Chersky used for his studies of Baikal were horizontal lines etched on the sheer cliffs around the Lake. Called “Chersky notches”, the lines are still visible today and are used by local people to gauge the water level in the Lake. Several landscape features are named after Chersky: a mountain near Cape Kotelnikovsky, a peak in the south of the Hamar-Daban ridge, and a hill near the source of the Angara, in the village of of Listvyanka. The massive heritage of scholarship left by the first European researchers on natural science, archeology and ethnography, their capacity to do such work in the severe Siberian climate and primitive living conditions , the versatility of their scientific interests and devotion to their calling seems astonishing to people today. 196 Native scientists Gleb Yurevich Vereschagin (1889-1944) was one of the founders of limnology, which is the science of lakes. Vereschagin came to Baikal for the first time in 1916, and devoted the rest of his life to its study. In 1924 Vereschagin designed a scientific station for the study of Baikal's biology and from 1925 to 1929 he headed the Commission for the Study of Lake Baikal. The scientist managed the creation of a biological station in the district of Bolshiye Koty, which was later transformed into the Limnological Institute of the Siberian Branch of the Russian Academy of Sciences. Staff at the station used a small vessel (9m long with a 9 horsepower engine) to carry out studies of Baikal's tectonics, hydrography, and flora and fauna. The work by Vereschagin and his staff confirmed that a considerable part of Baikal's endemic fauna and flora originated from the world's oceans. Biological station in Bolshye Koty Mikhail Mihailovich Kozhov (1890-1968) was an outstanding Siberian scholar and creator of the specific discipline called “Baikal studies”. Kozhov carried out studies of sponges, epischura, lop-eared maxillopids, bullheads, Baikal oilfish and other fauna. He spoke out against construction of the Baikal Pulp and Paper Plant, which is now the main source of pollution in Lake Baikal. A street in the central part of the city of Irkutsk has been named in Kozhov's honour. 197 Grigory Ivanovich Galaziy (1922–2000) was an academician, doctor of biology, and the author of more than 400 works and 8 monographs on Baikal. Working at the Limnological institute of the Siberian Branch of the Academy of Science of the USSR, Galazy set up a research station on Baikal, which he headed for 26 years. Galaziy's scientific work, the encyclopaedia entitled Baikal in Questions and Answers remains a core reference for both Russian and foreign researchers of Baikal. In 1995 Galaziy was selected as a member of the Committee for Protection of the Environment at the World Congress of Limnologists in Brazil and was awarded the Alexander Humboldt medal “For Study and Preservation of the Environment”. 198 Chronology of Baikal research 1640–1641 Arrival of an expedition under the Cossack leader, Kurbat Afanasievich Ivanov, on the western coast of Lake Baikal. 1667 The first approximate map of Baikal, in The Drawing of the Siberian Land, made by order of the Governor of Tobolsk, Peter Godunov 1701 The first accurate map of the Lake, in The Drawing Book of Siberia, by the Tobolsk Cossack, Semyon Remezov 1723–1727 The first scientific description of the Lake, presented by the German researcher Daniel Gottlieb Messershmidt, who was directly charged with the study of Lake Baikal by decree of Peter the Great. 1771–1772 An expedition led by the academician Peter Simon Pallas described the viviparous Baikal oilfish. Another member of the expedition, the academician Johann George Gmelin, gave a detailed account of the Baikal seal (nerpa). 1773 A detailed map of Baikal was compiled by the navigator Alexey Pushkarev, entitled “Special flat map of the Baikal Sea showing rivers and rivulets flowing into it and also the Angara flowing out of it”. 1855–1857 The first Siberian expedition of the Geographical Society led by the academician George Radde round Baikal. 1908 Publication of a 31-page atlas of Baikal (scale: one verst = one inch). 1916 Creation next to Lake Baikal of Russia's first nature reserve, the Barguzin Reserve. 1916 Opening of a biological research station in the village of Koty. 1925 Opening of a permanent Limnological Research Station of the Academy of Sciences of the USSR in the settlement of Marituy. 1925–1929 An expedition led by G.Yu.Vereschagin explored all principal areas of the lake. 1959 Depth of the Lake was measured at 1620 m using a weighted cable lowered from ice. 1961 Foundation of the Limnological Institute of the Siberian Department of the Academy of Sciences of the USSR, based on the Baikal Limnological Station in the village of Listvyanka. 1974 Depth of the Lake was measured at 1637m using echo-sounding measurements from a boat. 1986 Establishment of the Baikal and Zabaikalsky National parks and the Baikal-Lensky Reserve. 1991 Researchers dived to the deepest point on Baikal (1637m) in the "Pisces" deepwater submersible device. «Pisces» – a submarine device for deep penetration surveys. The first deep penetration in Baikal at a depth of 1410 was arranged in 1977. 199 1993 Publication of a scientific reference atlas of Baikal by the Russian Academy of Sciences using the findings of research carried out in 1961-1985. 1996 Lake Baikal was named a World Heritage Site by UNESCO. 1998 Deep-water drilling (600m) from an ice platform in the area of the Ushkani Islands confirmed that Lake Baikal is 15 million years old. 1999 The Federal law “On protection of Lake Baikal” was passed (Federal Law № 94 dated 5/1/1999). Environmental organizations based around Baikal inaugurated an annual “Baikal Day”, with the support of the Ministry of Natural Resources of the Russian Federation. Work began on reconstruction of the Baikal Museum in the village of Listvyanka. The exhibition area was enlarged by three times, six aquariums were installed, and a seal enclosure was created. 2001 2004 The first air-cushion amphibious vessel, the Hivus-10, began regular tourist operations on Baikal 2005 The Murmansk-Vladivostok Expedition-Trophy off-roader rally used a route across the ice of Lake Baikal for the first time . A 105th meridian ice camp was set up between the villages of Listvyanka and Tankhoi. 2008 The President of Russia issued a decree ordering the Eastern Siberia-Pacific Ocean oil pipeline to be rerouted away from Baikal (400 km to the north). Lake Baikal was judged one of Russia's “miracles of nature” based on the results of an Internet poll. 2009 It was decided to create Russia's first free economic zone for the tourism and leisure sector 180km from Ulan-Ude in the region of Buryatia adjacent to Baikal. A tourist complex in the zone should launch in 2017. 2010 The Baikal Pulp and Paper Plant in the town of Baikalsk resumed operations after standing idle for several years. Foul water will continue to be discharged into Baikal until August 2012. 2012 An international scientific conference, entitled “Baikal – a World Treasure”, was held at UNESCO headquarters in Paris on April 24. The conference discussed issues associated with the preservation of Baikal (a UNESCO World Heritage Site) and prospects for further studies to support sustainable development of the Lake ecosystem. The conference also took stock of results of the MIR-1 and -2 expeditions. 200 MIR Submersibles on Baikal The MIR is a deep-water manned device for oceanological research and rescue operations. The device can be lowered to a depth of 6 km, weighs 18.6 tonnes, is 7.8m long and 3.8 wide. Manufacturing cost per device in 1987 was 100 million Finnish markas (about 17 million euros). The device was designed by engineers of the Finnish company Rauma-Repola. The principal aims of the expeditions of MIRs on Baikal were: – visual study of the structure and development processes of the underwater ecosystem of Lake Baikal, behaviour of organisms at various depths, geological evolution and relief of underwater slopes of the Baikal trough; 201 – draw the attention of society (in Russia and worldwide), government structures and decision-makers at various levels to the issues of preserving Lake Baikal as a part of the world's natural heritage; – demonstrate ability of the Russian scientific community to implement large-scale research projects to a high standard. Installation of flags on the bottom of Baikal Paper cups: before and after deep penetration Oil in solid Planarians on the bottom of Baikal Baikal spongin A new species of sponge found in Baikal The Mir studies revealed hitherto unguessed-at secrets of Baikal. For example, it was found that about six tonnes of crude oil is discharged into the Lake each year from tectonic faults. It may be asked: “Why doesn't this oil appear on the Lake surface?” The oil is absorbed by microorganisms. How these organisms (worms and crustaceans) can live in places where the oil is discharged and how they process the oil is now one of the key riddles of Baikal studies. The other breakthrough was the first-ever discovery of gas hydrates in a fresh-water basin. Gas hydrates are characteristic of oceans and northern permafrost regions. Scientists believe that gas hydrates could provide an alternative fuel in the future. Gas hydrates are solid compounds formed of methane and water at certain pressure and temperature. 202 Underwater ecosystem of Baikal Dear friends! The MIR Submersibles on Baikal let the scientists see a wonderful and rich world of Baikal flora and fauna once more. We can't see many of them with an unaided eye. But without them Baikal would be incomplete. We will tell you about lower and higher plants of underwater world, about hydrocoles of Baikal. Diatomic algaes Diatomic algaes have been famous since the Jurassic period, they make about a quarter of all organical substance of the planet. They are unicellular, individual or colony-forming organisms, and they refer to true algaes. Diatoms' cells or siliceous algaes' cells are stripped of cellulose cover and surrounded with a hard siliceous shell outside. The thickness of the diatomic cell is 10 times thinner than a human hair. In the shape of form diatomic algaes are divided into two groups: with an actinomorphic or a bilateral shell. Most part of kinds the shell consists of two parts. Color plastids of diatomic algaes are of yellow-brown color depending on the set of pigments. An outside part of the shell is bigger, it reminds a cover which covers with its edges an inner, much less in size part of the shell. Diatoms propagate by dividing by halves, thus making two daughter cells out of mother one. Interestingly, that every daughter cell gets ony one fold of the mother's shell, and builds a second one on its own. Mass propagating happens when Baikal is covered by ice. Diatoms mainly live in the upper 25-meter layer of the lit Baikal water, but during storms and strong mixing of Baikal waters they descend to great depths. Diatomic algaes are biofilters of Baikal water. At present more than 12 thousand kinds of the algaes have been studied; they make a considerable part of the lake's plankton. 203 Volvox Volvox – are green algaes, with the diameter up to 1 mm; they make colonies at the water surface. They are referred to active colonial organisms. The size of one colony which has a from of sphere is 5 mm and it includes from 10 to 200 thousand cells. The sphere's mass is a semi-fluid jelly-like substance. Every cell looks like an independent protozoan, but together they make a colony. The cells have a pear-like form and two filaments connected by cytoplasmic bridges which jut out. Thanking to it volvox rolls over in the water, that's why it got its name “rolling”. While propagating some cells of volvox plunge into the sphere where they divide longitudinally making some new young colonies which further can jut out of the old volvox. At mass propagating cells can cause water blooming, painting it into green. Ulotrix After strong breakers Baikal coast is covered by green lumps of jelly-like consistence, by algaes from the bottom. They cover Baikal's bottom by separate girdles, by a 15-metre line from the coast to the depth. One can see the algaes well from a boat at calm weather. The nearest to the coast girdle of algaes is ulotrix, which is not endemic for Baikal. In summer they cover coastal stones where they can take roots, and in cold period they live at the lake's bottom in the form of spores. Ulortix is referred to green algaes and there are more than 25 kinds of them. Mainly they live in fresh waters. An algae's body reminds unbranched threads. All its cells are the same but the colorless one with the help of which the thread fastens to underwater stones, piles, snags. Inside the cell there is a girdle in the form of unended ring. The biggest part of the cell is occupied with vacuole, an organoid containing cell sap. The cell's cover is cellulose. 204 Star duckweed (Lemna trisulca) Star duckweed is a widely spread plant floating in the thickness of water. It grows in stagnant reservoirs. While blossoming the plant floats to the surface. Blossoming plants are egg-shaped, thicker and more solid than vegetative ones. In the thickness of water a star duckweed makes tangles where young fish can find food and shelter. It is a nice plant, together with other water plants it covers water surface with an emerald carpet. In autumn a star duckweed turns into a bud and descends to the bottom for wintering. As all green plants a star duckweed can undergo a photosynthesis, thus it can absorb carbonic acid and excretes oxygen. It consists of many semi-transparent leaves of bright-green color at length of 1 cm connected in three and more leaves. They grow in southern part of Baikal, in the Bay of the Small Sea, in the delta of the Selenga and other places on the lake. Batter dock (Potamogeton natans L.) A Batter dock or a water cabbage is a perennial plant of Potamogeton family. Its stalk is quite thick filled with aeriferous tissue, simple or a little branchy, round in section, 60-150 cm long with underwater and floating leaves. Leafstalks are long, can be flat, striated, grooved. Underwater leaves stripped of leaf plate start growing in spring and up to the time of blossoming they fell dawn. Floating leaves are numerous. Their oval leaf plates are of brown-green color, contain a lot of calcium. The leaves' length is about 8-12 cm and width is about 4-6 cm. The leaves can be used for curing scurvy, or as a wound healing or resolvent means. The essence of fresh grass is used in homoeopathy. The roots are considered to be eatable in cooked or baked forms. It blossoms in the middle of summer in the form of spicate inflorescence. In the batter dock's tangles fish and mollusks spawn and young fish find their defence. A batter dock can be found in the Angara, on the south-eastern coast of Baikal and rarely in Dauria. 205 Meakin The name “Meakin” has its origins from latin words – miros – numerous, phyllum –leaf. It's a plant with long stalks (up to 150 cm) making a thick lace of underwater tangles. Thanking to these numerous soft leaves the plant got the name “feather-leaf”, and the Germans call it “a milfoil”. They call them feather ones for their similarity with a bird feather. Meakin's branchy stalks catch on sculls and they often come off. The plant has creeping roots, and its sprouts can grow very fast. The leaves are brown or green. The flowers are small, plain, pinky. They are collected into a spicate inflorescence rising above the water up to 2,5 cm. The meakin's flowers are pollinated with the help of wind, and they blossom from July to August. In autumn bearing ripen which is divided into four nuts. When the meakin fades its inflorescence will go down to the water. The plant enriches the water with oxygen very well, it is a good forage for fish. In its tangles there are many small water organisms cleaning the water from unicellular algaes. The plant grows on different soils: from salted to peat ones. It can be met under the northern cape of the bay of Frolikha. Canadian pondweed (Elodea canadensis Michk) The Canadian pondweed is also called a water pest. Its motherland is Northern America. On Baikal it was fixed at the end of 70s beginning of the 80s. There is an idea that it appeared from the Irkutsk storage reservoir, and later it setteled all over the lake. The plant has very long branchy branches up to 3 m. The leaves are lightly-green, a little bit wavy with metalic shine. Its tangles make problems for navigation and fishery. The plant is a biological pollutant of water reservoirs. Negative ecological consequences of the plant's spreading appeared in Posolsk and in the delta of the Selenga river. It resulted in changes of biocoenosis' structure also in reducing of the number of main food fish. 206 Quillwort hirsure (Isoetes echinospora) The quillwort hirsure is a smal water plant in the form of tuft of curved green subulate leaves. The leaves grow from the thick roots. Interestingly, that in bosom of outer and medium leaves there are oval sporiferous bags. There are white spores in them the surface of which is covered with short brittle spinelets or high dense warts. The plant propagates by spores. It grows in water reservoirs on sandy, sandy-silty soils at the depth up to 2 metres The quillwort hirsure is a relict plant and it is registered in the Red Book of Russia. In Baikal's basin the majority of the plant's locations are in the northern edges of the lake (lake Frolikha, Verkhneangarsky bay, lakes Kicherskoye, Turkuit, Strakhovskoye, Karachaevskoye, Verkhne-Kicherskoye, Kulinda), also it is met in upper reaches of the Barguzin river (lake Amut, Yakondylon). Demersal Hydra The majority of representatives of acoelomates lives in seas and oceans. A freshwater polip is an exception; it can be met in the bays of Baikal. In Greek “hydra” means “a monster”. Its body fastens to any surface with the help of a sole. In the upper part of the body there is a mouth opening surrounded by 4-6 tentacles with the help of which hydras catch their prey - water fleas and other animals including tadpoles and young fish. If the latters touch tentacles where there are urticant capsules, they immediately shoot with long threads with poison. The prey is pulled by tentacles to the mouth opening and swallowed. Indigested remains of food the hydra throws out through its mouth, “wincing” with all its body. Hydras can change their places gliding on soles or tumbling over its heads. 207 Baicalia dybowskiana The shell of Baicalia dybowskiana reminds a small tower with its height up to 10–13 mm, which is 3 times exceed its width. A longitudinal back of this mollusk is clear, on its last side there are 8–12 ribs. The shell itself is delicate because of low mineralization of Baikal's water. The mollusk's body is represented by a muscle leg placed on the abdominal part of the body. Baicalia dybowskiana inhabits the depths of 600-800 m deep. Baikal gasteropods have an ability to eat organics filtered from water. Planarians (Rhimacephalus pulvinar) Planarians refers to flat turbellarian worms. There are more than 400 kinds of them on Baikal. On their abdominal part they have a mouth opening. While swallowing their food a gullet comes out. Through the body's covering one can see a furcate intestine. In the coastal zone of Baikal the worms are of different kinds. They have a various color and a variegated pattern. In the middle of the back there is a thin dark stripe. Under stones at the water's edge their size is 0,5–2 cm, at depths the size can reach 30 cm. Moving on the bottom of the reservoir the worms look for a victim. Further they envelop it with slime and slowly suck it inside the body. Eating sick and weak animals, planarians act as an orderly. Planarians can be met at depths from 8–10 m up to 100 m and deeper on silty and sandy soils. Its sizes are about 110 mm. 208 Manayunkia baikalensis It refers to Annelida polychaete worms. The length of the body is 7–8 mm, the length of tentacles is 1 mm. In winters and summers in the depth of Baikal one can meet millions of small “asters”. The manayunkia baicalensis look out of their cosy tubular houses, which they built in the thickness of soil and crowned them with higher small towers. The worms live in tubules, built of silty or sandy small parts joined with a special material. Their body consisits of many segments, each of them has a pair of setas. On the front end there is an aureole of tentacles, looking like a fan, with the help of which they can breathe and catch food. Manayunkia baicalensis inhabits sandy or silty soils, stones, sponges. They eat small invertebrate and ground remains. Water flea (Daphnia) The water flea belongs to the planktonic cancroids of the superorder of cladoceran. It is 0,2 mm up to 6 mm long. Outside the water flea is covered by chitinous covering reminding a medieval knight. At the edge of folds there are spinelets, and at the back edge there is a tail covered by spinelets. At the ends of extremities there are setas, which make “sculls” while swimming. They are also used for breathing and eating. Most part of the time water fleas spend in the water thickness moving by energetic jumps due to flapping of its feelers which are covered by special feathered setas. That's why their usual name is “water daphnia”. A she-water flea oviposits its eggs in the bag on the back. Mainly water fleas inhabit ponds and big puddles, where they eat different bacterias and phytoplankton. Also they can be met in Baikal, in its shallow places. 209 Baikal in figures • Water-collection basin 570 000 km2 • Baisin total area 300 000 km2 • Length of the Lake 636 km • Greatest width of the

diagonally from the island of Olkhon to Cape Valukan, peaks of which form the Ushkany Islands. Discovered by Gleb Yurevich Vereschagin in 1932. The Angara – A river, tributary of the Yenisei. The name's origins are connected with the character of its valley at the source, having the form of cleft or a gorge, through which the Angara flows out of Baikal. Babushkin – A town on the southeastern coast of Baikal, named after a revolutionary, Ivan Vasilevich Babushkin, who was killed here in 1906. Baklany – Used to describe a stone, island, or bay where many cormorants are found (Russian “baklan” = “comorant”). Vydrinaya – A tributary of Baikal. The river already had this name in the 17th century, when Nikolai Spafary, on his way to China in 1675, wrote: “The river Vydrinaya takes its name from the large number of otters and beavers found in it” (Russian “vydro” = “otter”) . Goryachinsk – A health resort in Buryatia with hot springs, discovered in 1753 (186 km from UlanUde). Davshe (Davsha) – A bay, river, or settlement. “Davshe” in Evenk means “meadows, a wide open district”. The central part of the Barguzin reserve is located. Dulan – A settlement in Kabansky District, on the southern slopes of the Gulf of Proval. “Dulaan” in Buryat means “warm”. Zasechnaya – A bay where I.D.Chersky scored a horizonal notch at a height of one metre above Baikal's water level on June 26, 1880. Chersky made such notches at many places on the Baikal coast in order to track changes in the Lake's water level over time. The intersections are now under state protection as belonging to the history of science. Zmeinaya – The name of a bay. The word means “grass-snake”. Grass-snakes in Baikal region are only found near to hot springs, so springs and the bays near to them are sometimes called “zmeiniye” or “kuliniye (from the Evenk “kulinda”, meaning ”many snakes”). Izhimey – The name of a cape on Olkhon Island. “Ezhin” in Buryat means “the owner, the master”. Mount Zhima, which forms the cape, is the highest point on Olkhon Island. Baikal's greatest depth (1637m) is located 8-10 km to the south of the cape. The Buryats view the mountain as sacred and many legends and traditions are connected with it. Kaltusnaya – A river in a waterlogged valley. “Kaltus” in Evenk means “a bog, a damp place”. Кotokel – A lake near Baikal. “Koto” in Evenk means “a palm tree, a knife, a club”, which is used to clear a track through scrub. The name has also been connected with Russian “koty”, which are a type of footwear worn in cold, damp weather, often by gold prospectors. Kotelnikovsky – The name of a cape, which is known for its hot springs (water temperature is about 70 degrees). In January 1724 the academician D.G.Missershmidt learnt in the Irkutsk Chancellery “that there is a hot spring by the Baikal-sea, at Kotelnikovsky, about 20 sazhens from the coast of Baikal”. F.K. Drizhenko writes in his navigation directions that “travelling by steamship near Cape Kotelnikovsky, the place of the springs can be seen from the large amount of evaporation above it.” Kultuk – A gulf at the southern end of Baikal and a village in the Barguzin Gulf. In the spring of 1647 Ivan Pokhabov “built the fortified settlement of Kultuk on Baikal-lake”. In Turkic “kultuk” means “a corner, a gulf”. 214 Keltegey (Kheltegey) – A cape and group of islands in the Chivyrkuisky Gulf. In Buryat the word “helegy” means “a slanting hillock”. The cape and the islands seem to lean to one side. Мaksimikha – A village and a bay. Old Buryat traditions recount that a Don Cossack explorer, Maxim Perfilyev, settled on the bank of the Barguzin Gulf and married a Buryat woman. The Cossack died, and his widow was known as “Maksimikha”. Small sea – The channel between the north-western coast of Baikal and Olkhon Island. Its southern part is called Olkhon Gates. “Small Sea” in Buryat is "narin-dalaj" (“narrow sea”). Upper Izgoloviye, Lower Izgoloviue – Capes on the Svyatoy Nos peninsula. An “izgologiye” is a cape on a river island, facing upstream. Оimur – A village on the bank of the Proval Gulf, and a small river in a boggy valley. “Оimokhо” in Buryat means “to ford a small river”. Or the name may come from the Buryat word for “a woodland track”. Olkhon – The biggest island on Baikal. It is partially forested, and its name comes from Buryat: "oy" is "wood", and “khon, khan” is a diminutive suffix. Peschanaya – A bay on the western coast of Baikal, exactly 100 km from the source of the Angara. It is one of the most picturesque places on Baikal's shoreline. “Peschanaya” means “sandy”. Posolskoye (Posolskaya) – A village and a railway station. They are named in honour of Erofei Zabolotsky, a Russian envoy to Mongolia and China who was killed here in 1650. The Posolsky monastery was founded at the place of his death in 1661. Proval – A gulf, named due to the earthquake in the northern part of the Selenga delta (January 12-13, 1862) when an area of the coastal steppe (about 200 sq. km) was swallowed up by the Lake. “Proval” means “fall, collapse” in Russian. Sarma – The name of a river and of a village. “Sarma” in Buryat means “a crossing on bulls”. The name is obviously connected with a crossing of this rough river. A strong local wind near to the river Sarma's mouth is also called “the Sarma”. It blows from the Primorsky ridge over the Lake at a speed of about 40 km/s, from the west and north-western, most often in October-December. Svyatoy Nos (Sacred Nose) – A peninsula connected to the mainland by a low, marshy isthmus. The peninsula has the profile of a huge nose. The Selenga –The largest tributary of Baikal. The name comes from the Evenk word “sele”, meaning “iron”. Snezhnaya – A tributary of Baikal. Its river basin and the northern slopes of Khamar-Daban have large amounts of precipitation, particularly snow (“Snezhnaya” = “snowy”). Тankhoy – The name of a bay, a port, a village and a railway station. “Тokhoy” in Buryat means “a curve, a bend”. Since 1969 Tankhoy has been the centre of the Baikal national park. Тuraly – The name of a cape on the northeastern coast of Baikal, between Khakusy and Shiraldy bays. The singing sands of Turaly are located on the southern side of the cape (“Тuraly” in Evenk means “musical, singing”), though a large part of them are now flooded. Uda – the right tributary of the river Selenga. The name "Uda" is believed to derive from a tribe, the Ude, which lived in the western part of Trans-Baikal region along the Orkhon and Selenga rivers in the 12th century. The name may also come from the Mongolian word “ude” meaning "midday". Frolikha – The name of a bay, a lake and a river on the north-eastern coast of Baikal, to the north of Ayaya Bay. The name is from the Russian surname, Frolov (a Cossack explorer). Khakusy – The name of a bay and a cape on the northeastern coast of Baikal. This sandy bay has an oval shape, with dark coniferous forest and vast fields of reindeer moss against a background of dome-shaped outcrops of the Barguzin ridge. The Evenk word “akushi” means "hot". 215 Khamar-Daban – A mountain ridge in Baikal region. In Buryat “hamar dabaan” means “a nose, a lifting”, and describes a high and difficult mountain pass or a mountain. There is another explanation of “hamar dаbааn” as deriving from a term meaning “a cedar mountain”. “Khamar-Daban” was originally the name for a small pass near Cape Shaman, which had a profile similar to a human nose. The name was later used to refer to the mountain system around the pass. Khuzhir – A village on Olkhon Island. In Buryat “khuzhar” means “saline soils, a place where salt comes out of the ground”. Shaman Stone – A stone rising from the water at the source of the Angara. In Evenk “saman” means “sorcerer, healer, priest”. 216 Baikal legends and fairy tales Now we will tell you some legends that were collected in the book by Lazar Eliasov, called “The Magician of Siberian tales”. These legends and stories of ancients times are a folk chronicle: different legends were passed down from generation to generation about how life appeared on the earth, where people come from, how different events happened, what the role of a particular historical people was, and why there are so many names and for different things in the world. How Baikal was made Old people tell this story about how Baikal was made. They say that there is very little soil on the Earth. Everybody knows that if you dig a hole for a few sazhens or even less, you come to sand, clay and stone. The deeper you dig, the less soil there is, and the more stones and other materials , which you cannot find on the surface. And further down, in the depths of the earth, there are only stones, and even further there is only water. There are many different stones in the ground, and there are stones that make water boil and gush, when it is poured on them. and many such stones can be found in the depths of the earth, many more than on the surface. About one thousand years ago, deep inside the earth, these stones and the water met. And the water boiled, when they met. Where should the steam go? It ran in various directions and pushed the earth, and the earth moved like a wave and swayed. The water seethed and seethd in the depths, then suddenly the water and the steam broke through to the surface and covered the low places. It couldn't go any further, as there were mountains all around, and that is how Lake Baikal was made. The lake never becomes less, because it is fed from under the earth, and they say that its water is connected to the Arctic Ocean. Long ago old men said that sometimes the pieces of a boat that was destroyed in Baikal were found in the Arctic Ocean, and boats that sank in the Arctic were found floating in Baikal. 217 On Baikal's origin Some people say that Baikal is a lake, but most call it a sea. There are legends, which explain the name “Baikal”. The Buryats call it “Baigal”. According to the legend of the Kabansk Buryats, the earth shuddered, a crack was formed, and red flames of fire blazed from it. burning everything around them. People prayed to the gods to stop the disaster, but the sky did not hear their prayers. So they began to ask “Bai, gal!” (“Fire, stop, please!”). And the fire began to subside when it heard these words. In the place, where it blazed, there was a huge basin, which filled with water. So this huge expanse of water was called “Baigal”. Where did the name “Baikal” come from? The Russians heard long ago that somewhere in the middle of Siberia there was a huge lake. But nobody knew its name. When Russian merchants and later Cossacks crossed the Urals and came to the rivers Ob and Yenisei, they heard that, further to the east, people live around a lake, where the water boils by day and by night. Those Russians also heard that the lake was rich in fish, and animals roamed the coast, and these animals had great value and had nothing to compare with them anywhere else in the world. So the Cossacks and merchants hurried on towards the sea-lake, and travelled for miles and miles without sleeping or feeding their horses, losing track of day and night, because they wanted so much to be the first to reach the lake and see its nature and find why it is waters ceaselessly boiled. The merchants and Cossacks journeyed for years and many of them died on the way, but the survivors eventually came to the Shaman Stone. It blocked the road and screened the sunlight, and there was no way around it to right or left, because of the high mountains, so high that if you looked towards their peaks, your hat would fall off and still you would not see the top of them. The Russians stood before the Shaman Stone and saw that they couldn't reach the sea, even though they could hear it roaring and breaking against cliffs. The merchants grieved and the Cossacks mourned, thinking they had come so far for nothing. They retreated, laid out their tents and began to think how to get round the Shaman Stone or round the mountains. But they couldn't come round the mountains, or the sea would swallow them. So the merchants and Cossacks stayed to live so near to the sea-lake, but without any chance of reaching its shore. They stayed there a long time until, to their good fortune, an stranger came to them who called himself “Buryat”. The Russians asked him to guide them to the coast, lead them around the sea and show them the land, where they had not yet been. But the Buryat said nothing, and went off into the forest. The Russians did not make him stay but let him go with God's blessing. The merchants and Cossacks felt sadness once again, understanding that they would die there and none of them knew how many days and months they had been there already. They even though of gathering their last strength and attempting to go back, but suddenly the Buryat returned and brought his son with him. He said: “I cannot get round Baikal with you – I'm too old to go round the Shaman Stone, my time is past. Take my son – he has clear eyes and the legs of a deer.” And the old man went back to the taiga and his son led the Russians by a new way, brought them to the coast and said: “Baigal”. The Russians asked him what it was, and he replied: “In our language it means a place of fire – before there was a burning fire here, which made the earth collapse and the sea flood in. Since then we call our sea 'Baigal'”. The Russian liked the name, so they began to call the sea “Baikal”. 218 The legend about an omul barrel According to the old byryat legend earlier winds-giants – Kultuk and Barguzin, old friends – bossed fish lands. They liked visiting each other, and played with each other and had some fun together. And for their fun they had a wonderful toy – an omul barrel: where it flew there omuls flew in very big amounts as if they wanted to get into that barrel. This made them have fun a lot. But once our hercules fell in love with Sarma, a mountain epic-heroine, the mistress of the Small sea. She had a very severe character comparing with the ones of Barguzin's and Kultuk's. Also she was much stronger than they were. They both would like to have a wife like Sarma. And they both wanted to marry her. But Sarma answered that she would marry the one who would bring a magic barrel to her first. “I would also like to have a lot of omul in my Small sea”. The hercules decided that it was a triffling matter, though they didn't want to yield. And the barrel got in a very bad condition: it flew and creaked all the time. At last they managed to catch the barrel, but all over sudden they stood frozen: no one couldn't make the barrel free – their force was equal. But as soon as they decided to fight again, the barrel somehow disappeared from their hands and it went down the water...It turned out that Baikal himself took it away to finish the quarrel. And Sarma didn't marry anyone. Till nowadays the giantswinds quarrel with each other who is better, thus arousing waves on the lake. 219 The Beauty Angara A ballet, based on this legend, was written and performed in the State Ballet and Opera House of Buryatia in the 20th century. The composers were Lev Knipper, Bau Yampilov, the choreographer was Mikhail Zaslavsky, the set was by Aleksandr Timin, and the main roles were taken by Larisa Sakhyanova and Petr Abasheev. In 1972 the ballet was awarded a state prize and there have been more than 500 performances at the Buryat State Ballet. Long-long ago in our region there was mighty, grey knight, called Baikal. Nobody could equal him in strength and wealth. When he grew angry, his waves reached to the mountains and rocks began to crack. Many rivers and streams were his servants. Old Baikal had only one daughter and her name was Angara. She was the most beautiful daughter in the world. Her father loved her very much, but he was strict with her and kept her secluded, deep in his waters, never letting her out. Angara was very sad and dreamt of freedom. Once, a gull from the Yenisei arrived on the shores of Baikal. The gull landed on a rock and began to tell of the free life in the Yenisei steppes. The gull told of Sayan and his handsome and glorious son, Yenisei. Angara heard the gull's story and felt even more sad. Later, Angara also heard about Yenisei from mountain streams and her sadness grew even greater. She decided to see Yenisei, come what may. But how could she break free from her prison, and the high walls of the palace? She began to pray: Oh, Tengerian Gods, Have mercy on this imprisoned soul, Be not hard and cruel To me, stranded and helpless. Understand that my youth is being denied By my father Baikal. Give me strength and courage To break free from these walls. 220 When Baikal found out that his daughter wanted to run away he locked her up even more securely and started to look for a husband for Angara among his neighbours, because he didn't want his daughter to go far away from him. Old Baikal decided to marry her to the rich and brave Irkut. He sent his servants for Irkut. When Angara heard of this, she cried bitterly. She begged her father not to marry her to Irkut, whom she didn't love. But her father was firm, and locked Angara away even more deeply and locked her door with crystal locks. Angara cried again for help. And the mountain streams and rivers heard her and decided to help. They started to wash away cliffs and rocks along the shore The wedding night approached and on the night before the wedding, when Old Baikal was sleeping soundly, Angara broke her crystal locks and escaped from her prison. And the brooks and rivers cleared a way for her on the Lake shore. And at last the way was ready. Angara broke loose from the walls of stone and rushed to her beloved Yenisei. Old Baikal was awoken by bad dreams. He quickly got up, heard the noise and realized what had happened. In fury he ran out of his palace, took a rock and threw it after his escaping daughter with a curse. But it was too late. His stone missed Angara, who was already far away, but it still lies at the place where Angara broke free, and is called the Shaman Stone. Old Baikal still wants his runaway daughter back. And if we move the Shaman-Stone then Old Baikal will burst his shores and catch up with Angara, flooding everything in his path. 221 Where did the Selenga take her name from? It was a long, long time ago. So long time ago that nothing has remained from those days, except for a report that is passed from grandparents to grandsons, and from fathers to sons. In those time the biggest Tungus clan was wandering on the shore of Baikal, where the Angara begins, not far from where Irkutsk is today. They wandered across the taiga until they met another tribe. People can always find a common language, and here it was particular easy because the two tribes were related. The other tribe were Tungus from the Chilchigir clan, who led a nomadic on the northern shores of Baikal, where the town of Nizheangarsk stands today. The Baikal Tungus got to know the Chilchigirs. And the Chilchigir Prince told them: “Our ancestors, maybe grandparents or greatgrandparents lived here, where you Baikal Tungus are living now. But a misfortune occurred. Our grandfathers went onto Baikal to hunt for seals, but the ice was fragile and their block of ice separated and drifted away from the shore. They drifted for a very long time. They crossed the Lake on the block of ice and landed on the other side of Baikal. They couldn't get back, so they had to live in the new place. They found it hard, but they survived and started to hunt again. What else could a Tungus do? Once, while they were hunting they found a big river. The hunters went up the river and found another river which flowed into it. Our ancestors explored those rivers for a long time, but they met no one. Those places were deserted, though very rich in birds and animals. But there's no place like home, and our home is here, where the Shaman Stone protects us. If the Stone is moved, then everything will be flooded.” The Baikal Tungus listened to their relative and asked: “What's the name of that big river?” 222 “Have a little patience,” the Chilchigir Prince replied. “You will soon understand.” He looked at them all, saw that he had their attention and continued his story: “We lived on the other side for a long time, we got used to the big river, but we had trouble like our grandfathers. When we were fishing, a terrible thunderstorm began. Our boats were destroyed, and we barely managed to get to the shore that our ancestors had left a long time ago.” The Baikal Tungus were curious and they asked about the big river's name one more time. The Prince replied that the river had no name, because people haven't reached that river yet, and only people could give names to rivers. “Where does it flow into?” “Into Baikal” the Prince replied. And then the Baikal Tungus understood that the big river flows above Baikal, and rivers like this are called “solonga” in Tungus. Later the Buryats and Russians distorted the word and called the river “Selenga” The name has remained to this very day. What I have told you is the truth – I have heard it many times from the Tungus. That's how Selenga got its name, very simply. Nowadays people still give names to nameless rivers based on various things. Each river has its own name. Both the Evenks and the Buryats have similar legends, but this one seems to be the most full and make the most sense. Magay first hard it from a hereditary Baikal Cossack, Ivan Zasadin, at the time of the Civil War. This is one of the variants that was recorded from Magay's words in February 1948. Egor Ivanovich Sorokovnikov-Magay was born into a Buryat-Russian family in the village of Taloye (Tunkinsky District) in the Republic of Buryatia. His father's ancestors were Buryats, from whom he took his second generic name, “Magay”, which is a name from legend. His father was a hunter, a violinist, and an expert on fairytales. Egor Ivanovich received most of his repertoire from his father. In the 1930s he was admitted as a member of the Writers' Union of the USSR. Shortly before his death he was awarded the title of Honored Artist of the Buryat Republic. 223 Buryat Folk Fairy tales How lions died out in Siberia A long time ago there were lions living in Siberia. They were shaggy and overgrown with long hair and they were not afraid of the cold. Once a lion met a wolf and asked: – Where are you running to as if you were crazy? – I am scared that I will be killed ! – And who has put such fear into you? – A man who sneezes loudly. He sneezed once and killed my brother, the second time my sister, and the third time he wounded my leg. You see, I am limping. The lion growled, so that the mountains shook and the sky wept. – Where is this man who sneezes loudly? I will tear him to pieces! I will throw his head over the distant mountain and his legs to right and to left. – Don't even think of it! He won't spare even you! Run for your life! The lion took him by the throat: – Show him to me or I will strangle you! And they started off. On their way they met little shepherd-boy. – Is it him? – asked the lion. – No, it isn't. He has not grown up yet! They came to the steppe. On a hill there was a tired old man, who was tending a herd. – Is it him? The lion bared his teeth and grinned. – No, it isn't. He is already too old. They went further. And suddenly they met a hunter on a fast horse. He had a weapon over his shoulders. The lion didn't have time to ask the wolf a question, because the hunter took his gun and fired a shot. The lion's long hair caught fire. The lion ran off and the wolf followed him. They stopped in a dark ravine. The lion rolled on the ground and growled madly. The wolf asked him: – He sneezes strongly, doesn't he? – Shut up! You see, I am naked! I have only my mane left and the tufts of hair on my tail. I am shivering with cold. – And where can we run to escape the loud-sneezer? – Go to the forest! The wolf disappeared into the furthest forest, but the lion ran to a hot country, to a desert. 224 A mouse and a camel Once a very big and very foolish camel argued with a small but very clever mouse. – I will see the sunrise before you! – said the camel. – No, I will see it first! – answered the mouse. – Really? But you are not bigger than my eyelash. I am a mountain in comparison with you! You can't compete with me! They argued the point again and again, and eventually they decided to see who was right. They waited for the morning. The camel thought to himself: – I am a hundred times bigger than this mouse. So, I will see the sunrise a hundred times quicker. And as the earth is round, wherever the sun rises from, I will see it in any case. The foolish camel! He did not know that the sun always rises in the east. The camel turned to the south and began waiting. And the little mouse climbed onto the camel's hump and started looking to the east: – There is the sun! I have seen it before you! How foolish you are! – the mouse shouted, and jumped down to the ground. The camel turned round and saw that the sun had already risen. It seemed to be laughing at him. He became angry terribly – with the mouse, of course, not with himself. He chased the mouse, wanting to trample her. But the clever mouse managed to hide in the ashes of yesterday's fire. Since then the camel always lies down and rolls in ashes every time he sees them. He smears himself from head to feet and feels very pleased with himself, because he think s that he is quits with the wretched mouse. So the little mouse was cleverer than the big camel. That's why the Buryats call the first month of the year “the month of the mouse”. 225 A horse and a red deer In ancient times the red deer had four eyes. He was proud of it, and he also thought that he was the fastest animal on four legs. Once the red deer met a horse and said to him: – You can run very well, but nevertheless you are not so fast: you never will catch up with me! – You are wrong! - said the horse, - I will catch up with you! – And how will you do it? – asked the red deer. – I will put a man on my back and tell him to ride me. Then I will catch up with you. The red deer laughed and said: – You will not catch up with me whatever you do! Especially with a man on your back! They made a bet and set the time of the race. The red deer went to pasture and gather strength. And the horse went to a man and said: – Sit down on me and ride me! We will race with the red deer! – All right! – answered the man. The horse and the red deer met in the open field on the appointed a day and they raced. First the red deer was ahead, but the man began goading the horse, so the horse caught up with the red deer and left him behind. The red deer wept bitterly in shame. And he cried so hard and so long, that he sobbed out two of his four eyes. Since then all red deer have marks below their eyes. These are traces of the cry-eyes. A hare and a snow The snow said to a hare: – I have a headache. – You are thawing, and that is probably why you have a headache, - answered the hare. He sat down on a tree stump and wept bitterly: – I am so sorry for you, snow. .. I hid myself in you and hid from the fox, the wolf and the hunter. And how will I live without you? Any raven and any owl will see me and peck me to death. I will go to the master of the forest and ask him to save you for me. But the sun was high and was shining hot. The snow thawed and ran from the mountains. The hare pined and cried louder. The master of the forest heard the hare. He listened to his request and said: – I will not argue with the sun and I can't preserve snow. But I will change your white coat for a grey one. In the summer you will easily hide among dry leaves, brushes and grass. The hare was delighted with this. Now he always changes his white winter coat for a summer one. 226 Our love for Baikal: Poems about the Lake I. Severyanin Baikal I've dreamt of Baikal since my childhood, And at last I've seen Baikal. We sailed over it and the mountain ridges flashed, And the cedars looked down from the cliffs. I remember many different stories And many songs Of this lake-like sea, Of this Holy Baikal. We sailed from one pier to the next. Evening came. It was cold. The time was in May. We took a train and went away. We went to China in that blue train. Many times my soul has pined, Wishing to come back again. I still do not know Baikal: To see it is not to know it. N.Damdinov Baikal is beneath me now. From the mountain-top I try to encompass the smoothness Of its glittering, fairly-tale immensity. Here from the cliff I can see, Where Chersky once stood, Over there a breath of wind, Brings a leisurely wave to life: Probably the Barguzin Ruffled the water, And waves rush to the foot of the cliffs Like a flock of swans. They are without number, without end Numerous, endless amid the silence. The carefree wave-song murmurs unceasing For millions of years Amid the dumb silence of mountains. And the song does not seem too long, I could listen to it forever. I've forgotten about tomorrow, I can't worry about my descendants! Holy Baikal, darkening with rage, Punish me like a boy... 227 D.Ulzituev Homecoming Oh, Baikal, The eyes of my mountain land, I have returned to you From far away! The light-chestnut horses' legs Gallop and gallop Across you. Huge clouds sail over you. Exiled in great cities I pined for your Low, saddle-like, springing waves, The dashing strength of Tuneful Russian words Unexpectedly Powerfully Suddenly wells up inside me. Baikal, I bring you A low bow of reverence From Mother Volga and fair-haired birch trees! The ground rose to meet me On all sides; I have brought my heart To you, my wind and mountains! A blue haze shines In the foggy distance And ships sail peacefully Across it. Again the gulls are flying Over the glassy water. The blue arch of heaven Is reflected in the face of the deep. …On roads and highways I often dreamt Of seeing Baikal first quiet, Then threatening. And now I see it: the water is blueness. Islands of white clouds Are reflected in its surface. A blue haze shines In the foggy distance … The road calls me again, But to part with the Lake is such sorrow! D.Zhalsaraev The Baikal Song You said: “How beautiful Baikal is!” If I am as you say, This virginal beauty was gifted to me By the flowering earth. This song is washed by my waves And taken up by the cedars. You said “Baikal is crystal-clear…”. If I am as you said, The purity of crystal waters were made blue By the transparent vault of heaven. This song is washed by my waves And taken up by the gulls. You said “How powerful Baikal is!”. If I am as you said, This fairy-tale riot of strength Was given me by Great Geser`s breath. This song is washed by my waves And taken up by the cliffs. You said “The bottomless depths of Baikal”. If I am as you said, I owe my depth To the golden soul of the people. This song is washed by my waves, And bursts forth from my heart. 228 E. Golubev Baikal I was born and raised in backwoods In secret woods of the Urals, Where nightingale's song was heard In a night above the Kama, Where standing on a ridge, Passing through thick mist, You see shine of oriental lakes And Western Russia's margin. I thought the best place All over the world is the Urals, But when I saw the BaikalThe first time I doubted it. …The train was going, passing by Margin, woods and stopped. In the foggy distance Blue mirage is shining And peacefully are going The ships on it. Again the gulls are flying Above the glassy water. The blue arch of heaven Is reflected in the face of water. …In the roads and ways I frequently dreamt See the lake first quiet, See the lake then horrified. And have seen: the water is blueness. Islands of white clouds Are reflected in surface. In the foggy distance Blue mirage is shining But the road is calling, And it is a pity to part with the lake! I see a glorious lakeThe sacred Baikal. I look down- there's blue lake I look up- there's blue sky, Only white clouds above Float quietly, Only gulls fly above Stark water. Only in the sky There is a golden Sun limb. And it looks, can't see enough In the mirror of the waters, Grey mountains, majestic Big round dance. High giants Stark granite The blue of this abyss, As a mystery, it keeps. Having dreamt about frredom, Baikal will break out, Frothing its waves, Splashing at the cliffs. It will hit with big wave Into the chest of capes. The giants don't stand Like a granite wall. It urges onto the mountain the clouds With a thuderstorm, But the the thunderstom is weak, Like an old man's hand. 229 Bibliography and recommended literature 1. Abaev N.
