The native, ordinarily, does not take money for his skins, but various kinds of necessaries. Reducing it all, however, to a monetary basis, we find that he receives for sable skin ten to thirteen roubles; red-fox skin, two to three roubles; white-fox skin, one and a half roubles; black-fox skin, fifty to one hundred and fifty roubles; blue-squirrel skin, thirty-five cents; unborn-deer skin, twelve cents; turbogan (kind of coon), fifteen cents; yearling-deer skin, seventy-five cents; sea-dog skin, one rouble; black-bear skin, seven roubles; brown-bear skin, five roubles; white-bear skin, twenty-five roubles; walrus rope, two cents a yard; walrus ivory, from five cents to one and a half roubles a tusk; mammoth tusk, five to six roubles; fur coats, one and a half to five roubles; boots, twenty-five cents to seventy-five cents a pair. For an ermine skin he is wont to receive two needles or a piece of sugar as large as a thimble. In exchange for these commodities the traders give tea, sugar, powder, lead, cartridges, tobacco, bar iron one inch wide by a quarter of an inch thick, needles, beads, and various other trinkets. When the goods are marketed it is found that the company makes anywhere from one hundred to one thousand per cent. profit. Tea, the article most called for, allows only one hundred per cent. profit. On sugar some three hundred per cent. is made, and on the trinkets and other miscellaneous goods anywhere from five hundred to one thousand per cent. is made. [Illustration: Ghijiga River in Winter.] Several significant facts are to be deduced from this list: first, the low price that is paid for sables compared with the prices they bring in the European market; second, the comparatively high price the skin of the black fox brings, although it is only a fraction of what it costs at home (a single skin has brought as high as four thousand dollars in Paris); third, the extremely low cost of ermine; and fourth, the fact that there is no active trade in mammoth tusks, although they are plentiful. They are often ten feet in length, and it might be supposed that they would contain ivory enough to make them worth much more than they bring; but the fact is that it is fossil ivory, and the outside of each tusk is so far broken and decayed that only the very center of the tusk contains marketable ivory. The common rule is to give the natives one year's credit; the tea, sugar, tobacco, and other articles which they receive this year being paid for by the skins which they bring next year. The plan works well, for the natives are scrupulous in the payment of their debts. And furthermore, the traders, being on the spot, have a wide personal acquaintance among the natives and know just whom they can depend upon.
