mountains, on account of the infinite number of immense rock crystals, which, they say, cover their surface, and which, when they are not covered with snow, or in the bare places, reflect to an immense distance the rays of the sun. The name of Rocky mountains was given them, probably, by later travellers, in consequence of the enormous isolated rocks which they offer here and there to the view.[171] In fact, Millet's rock, and M'Gillivray's above all, appeared to me wonders of nature. Some think that they contain metals, and precious stones.
With the exception of the mountain sheep and goat, the animals of the Rocky mountains, if these rocky passes support any, are not better known than their vegetable and mineral productions. The mountain sheep resorts generally to steep rocks, where it is impossible for men or even for wolves to reach them: we saw several on the rocks which surround the Mountain House. {302} This animal has great curved horns, like those of the domestic ram: its wool is long, but coarse; that on the belly is the finest and whitest. The Indians who dwell near the mountains, make blankets of it, similar to ours, which they exchange with the Indians of the Columbia for fish, and other commodities. The ibex, or mountain goat, frequents, like the sheep, the top and the declivities of the rocks: it differs from the sheep in having hair instead of wool, and straight horns projecting backward, instead of curved ones. The color is also different. The natives soften the horns of these animals by boiling, and make platters, spoons, &c., of them, in a very artistic manner.[172]
