Although much engrossed by fishing, the Ostyaks do not neglect the chase. Their thick woods abound in the better kinds of fur animals, and the annual tribute of two sable skins, payable by each family to the Russian government, is not very difficult to obtain. It is seldom found necessary to pay an equivalent in other skins. Although quite the beginning of winter, Mr Erman's host, in an Ostyak village, showed him a fine sable skin, which he kept in a strong box, like a treasure, concealed in a corner of his dwelling. Its value was diminished by a yellowish tinge, ascribed to the animal's having lived in a wood where there was too much light. Besides sable and squirrel, the reindeer, the fox, the glutton, and the elk, are objects of chase. Mr Erman tried to get at the fact of the enmity said to exist between the two latter animals. The reply to his inquiries was the old story current in Europe--how the glutton leaps from a branch on the elk's neck, and keeps his seat till the death of his steed. No one, however, had seen any thing of the kind: it was matter of tradition, handed down from their dead fathers. The ermine is taken in traps. The fox is in great variety, the most esteemed being the crossed stone fox, whose colour is partly a grayish yellow, partly white, so distributed that the grayish parts unite prettily to form a cross, one bar of which extends along the back, whilst the other stretches obliquely down the middle ribs to the belly. The fur of this animal is greatly prized by the Russian clergy, for whom pelisses, covered with natural crosses, are made from it. The latitude of the town of Beresov is the headquarters of the Siberian beaver, hunted not for the fur but for the precious castoreum or beaver-stone, to which such great medical virtues are ascribed. Attempts have been made in Germany to obtain from the beavers of that country a product which might replace that of Siberia; but all in vain. The fine quality is only to be had in the far north, where, as Mr Erman fancifully observes, nature scatters animal perfumes in place of fragrant flowers. "The Kosaks and Russian traders have exalted the beaver-stone into a panacea.... To the sentence, 'God arose, and our enemies were scattered,' the Siberians add, very characteristically, the apocryphal interpolation, 'and we are free from headache.' To ensure this most desirable condition, every one has recourse, at home or on his travels, and with the firmest faith, to two medicines, and only two, viz., beaver-stone, or beaver-efflux, as it is here called, and sal-ammoniac." From the strength of the castoreum, the Siberians infer that other parts of the animal must possess peculiar virtues. Gouty swellings are said to subside rapidly when rubbed with the fat, and the beaver's teeth are popularly believed to cure toothach.
