For the benefit of future travellers I may state that the wares most in demand are large sewing and darning needles, pots, knives (preferably large), axes, saws, boring tools and other iron tools, linen and woollen shirts (preferably of bright colours, but also white), neckerchiefs, tobacco and sugar. To these may be added the spirits which are in so great request among all savages; a currency of which, indeed, there was great abundance on the _Vega_, but which I considered myself prevented from making use of. In exchange for this it is possible to obtain, in short, anything whatever from many of the natives, but by no means from all, for even here there are men who will not taste spirits, but with a gesture of disdain refuse the glass that is offered them. The Chukches are otherwise shrewd and calculating men of business, accustomed to study their own advantage. They have been brought up to this from childhood through the barter which they carry on between America and Siberia. Many a beaver-skin that comes to the market at Irbit belongs to an animal that has been caught in America, whose skin has passed from hand to hand among the wild men of America and Siberia, until it finally reaches the Russian merchant. For this barter a sort of market is held on an island in Behring's Straits. At the most remote markets in Polar America, a beaver-skin is said some years ago to have been occasionally exchanged for a leaf of tobacco.[238] An exceedingly beautiful black fox-skin was offered to me by a Chukch for a pot. Unfortunately I had none that I could dispense with. Here, too, prices have risen. When the Russians first came to Kamchatka, they got eight sable-skins for a knife, and eighteen for an axe, and yet the Kamchadales laughed at the credulous foreigners who were so easily deceived. At Yakutsk, when the Russians first settled there, a pot was even sold for as many sable-skins as it could hold.[239]
