The bear family likewise furnishes many skins to the Siberian furrier. That of the young brown bear (_Ursus arctos_) is highly esteemed for the trimming of pelisses; but that of the older animal has little value, and is used, like that of the polar bear, as a rug or a foot-cloth in sledges. The lynx is highly prized for its very thick, soft, rust-colored winter dress, striped with darker brown. It attains the size of the wolf, and is distinguished from all other members of the cat tribe, by the pencils of long black hair which tip its erect and pointed ears. It loves to lie in ambush for the passing reindeer or elk, on some thick branch at a considerable distance from the ground. With one prodigious bound it leaps upon the back of its victim, strikes its talons into its flesh, and opens with its sharp teeth the arteries of its neck. Though singly of but little value, as a thousand of its skins are worth no more than one sea-otter, the squirrel plays in reality a far more important part in the Siberian fur-trade than any of the before-mentioned animals, as the total value of the gray peltry which it furnishes to trade is at least seven times greater than that of the sable. Four millions of gray squirrel skins are, on an average, annually exported to China, from two to three millions to Europe, and the home consumption of the Russian Empire is beyond all doubt still more considerable, as it is the fur most commonly used by the middle classes. The European squirrels are of inferior value, as the hair of their winter dress is still a mixture of red and gray; in the territory of the Petschora, the gray first becomes predominant, and increases in beauty on advancing towards the east. The squirrels are caught in snares or traps, or shot with blunted arrows. Among the fur-bearing animals of Siberia, we have further to notice the varying hare, whose winter dress is entirely white, except the tips of the ears, which are black; the Baikal hare; the ground-squirrel, whose fur has fine longitudinal dark-brown stripes, alternating with four light-yellow ones; and the suslik, a species of marmot, whose brown fur, with white spots and stripes, fetches a high price in China. It occurs over all Siberia as far as Kamchatka. Its burrows are frequently nine feet deep; this, however, does not prevent its being dug out by the hunters, who likewise entrap it in spring when it awakes from its winter sleep.
