From Pole to Pole: A Book for Young People

by Sven Anders Hedin

If you lay your left hand on a map of Tibet so that the part nearest the wrist touches the Pamir, the flat of the hand covers the region of central Tibet, where there is no drainage to the ocean, but where the country falls instead into a number of isolated lake basins. Your thumb will represent the Himalayas, the forefinger the Trans-Himalaya, the middle finger the Karakorum, the third finger the Arka-tagh, and the little finger the Kuen-lun. The highest mountain ranges of the world are under your fingers; and also, as the longest finger is the middle of the five, so the Karakorum is the central range of Tibetan mountains.

Now let a little stream of water fall on the back of your hand as you hold it on a table with the fingers spread out. You will see that a tiny quantity remains on the back of the hand, but that the greater part runs away between the fingers. Thus it is in Tibet. The water poured on your hand represents the rain of the south-west monsoon, which falls more abundantly on the eastern part of the country than on the western. The water which stays on the back of the hand represents the small scattered salt lakes on the plateau country which has no drainage to the sea, while the large quantity which runs off between your fingers represents the large rivers which flow between the ranges.

TIBET.

Of these rivers two stream eastwards: the Yellow River (the Hwang-ho), which falls into the Yellow Sea, and the Blue River (the Yang-tse-kiang), which empties its waters into the Eastern Sea. The others run southwards, the Mekong into the China Sea, the Salwin, Irawaddy, and Brahmaputra into the great inlet of the Indian Ocean which is called the Bay of Bengal. A large quantity of water runs off along the outer side of your thumb; this is the Ganges, which comes down from the upper valleys of the Himalayas. And, far to the west, nearest to the wrist, you find two rivers with which you are already acquainted: the Indus, which flows southwards into the Arabian Sea, and the Tarim, which runs north and east and falls into Lop-nor.

The Himalayas are the loftiest range on earth, and among their crests rise the highest peaks in the world. Three of them should be remembered, for they are so well known: Mount Everest, which, with its 29,000 feet, is the very highest summit in the world; Kinchinjunga (28,200 feet), and Dhwalagiri (26,800 feet). Mount Godwin-Austen in the Karakorum is only about 650 feet lower than Mount Everest.

The Himalayas present a grand spectacle when seen from the south. No other mountain region in the world can vie with it in awe-inspiring beauty. If we travel by rail from Calcutta up to Sikkim we see the snow-clad crest of the Himalayas in front and above us, and Kinchinjunga like a dazzling white pinnacle surmounting the whole. We see the sharply defined snow limit, and the steep, wooded slopes below. If it is early in the morning and the weather is fine, the jagged, snowy crest shines brightly in the sun, while the flanks and valleys are still hidden in dense shadow. And during the journey to the great heights we shall notice that the flora changes much in the same way as it does from South Italy to the North Cape. The last forms of vegetation to contend against the cold are mosses and lichens. Then we come to the snow limit, where the mountains and rocks are bare.

North and Central Tibet have a mean elevation of 16,000 feet; that is to say, one is almost always at a greater height than the summit of Mont Blanc. Where the plateau country is so exceedingly high the mountain ranges seem quite insignificant. We have spoken of five great ranges, but between these He many smaller, all running east and west.

What a fortunate thing it is for the people of Asia that the interior of the continent rises into the tremendous boss called Tibet! Against its heights the water vapour of the monsoon is cooled and condensed, so that it falls in the form of rain and feeds the great rivers. Were the country flat like northern India or Eastern Turkestan, immense tracts of the interior of Asia would be complete desert, as in the interior of Arabia; but as it is, the water is collected in the mountains and runs off in all directions. Along the rivers the population is densest; around them spring up cities and states, and from them canals branch off to water fields and gardens.

You know, of course, that Asia is the largest division of land in the world, and that Europe is little more than a peninsula jutting out westwards from the trunk of Asia. Indeed, Asia is not much smaller than Europe, Africa, and Australia put together. Of the 1550 millions of men who inhabit the world, 830 millions, or more than half, live in Asia. If, now, you take out your atlas and compare southern Europe and southern Asia, you will find some very curious similarities. From both these continents three large peninsulas point southwards. The Iberian Peninsula, consisting of Spain and Portugal, corresponds to the Arabian Peninsula, both being quadrangular and massive. Italy corresponds to the Indian Peninsula, both having large islands near their extremities, Sicily and Ceylon. The Balkan Peninsula corresponds to Further India (the Malay Peninsula), both having irregular, deeply indented coasts with a world of islands to the south-east, the Archipelago and the Sunda Islands.
