Without doubt one of the earliest uses to which man has put the lower animals is that of clothing his body in their captured skins. The acquisition of furs has been a special feature of the colder climes. It is obviously also a feature of discovery and conquest, for it is the wilderness only which yields any considerable number of fur-producing animals. Thus navigation, commerce, discovery, invention, economics, finally international wars and policies, have been rooted to a large degree in this primal business. The fur-hunters have held the hunters of gold and precious stones and spicery a close race in the rank of world movers. Indeed it may well be questioned whether results of greater moment to humanity have not proceeded from the quest for furs than from that for gold. The Spaniards expended their energies in the gold and silver hunt in Mexico and Peru and annihilated the races of those lands in their pitiless rapacity. The other great exploring nations of the sixteenth century, especially the French, while not indifferent to the possibility of encountering the precious metals, found more certain and permanent results in the less feverish and dazzling pursuit of the wild animals of the wilderness. Neither the hunters for gold nor those for peltries were the state-builders and home-builders without whom our American Union would not exist. But they were the avant-couriers of both. Our land of Oregon has had the peculiar fortune of being opened by both for both. China furnished the most active and convenient market for furs to those who secured their supplies on the Pacific Coast of North America. The Russians were the first Europeans to enter the Chinese market, and they began their voyages as early as 1741. The sea-otter seems to have had its chief habitat on the Pacific shore from Oregon to Alaska, and, as the ships of all nations began to crowd upon the location of the fabled Strait of Anian, the trade with the natives for these precious furs became constantly augmented, until the curious and interesting creatures, so fatally attractive, were added to the long list of "lower creatures" whom the greed of the "higher creatures" has exterminated. A book by Coxe published in London in 1787 first made known to the English-speaking people the rich profits of the Russians from the transportation of the sea-otter skins to China. He instanced a case of a profit of $50,000 from a single cargo. It had, however, been known in 1785 from the report of the voyage of Captain Cook that the North-west Coast of America contained a new source of wealth from the accumulation of these furs by the Indians and their eager desire to trade them for trinkets and implements of civilised manufacture.
