3. The _Rocky Mountain Sheep_--frequently called the _Bighorn_ by our western hunters--is found on the prairies west of the Mississippi, and throughout the wild, mountainous regions extending through California and Oregon to the Pacific. They are larger than the Argali--which in other respects they resemble--and are probably descended from them, since they could easily cross upon the ice at Behring's Straits, from the north-eastern coast of Asia. Like the Argali, when caught young they are readily tamed; but it is not known that they have ever been bred with the domestic sheep. Before the country was overrun by the white ram, they probably inhabited the region bordering on the Mississippi. Father Hennepin--a French Jesuit, who wrote some two hundred years ago--often speaks of meeting with goats in his travels through the territory which is now embraced by Illinois, Wisconsin, and a portion of Minnesota. The wild, clambering propensities of these animals--occupying, as they do, the giddy heights far beyond the reach of the traveller--and their outer coating of hair--supplied underneath, however, with a thick coating of soft wool--give them much the appearance of goats. In summer they are generally found single; but when they descend from their isolated, rocky heights in winter, they are gregarious, marching in flocks under the guidance of leaders.

They are covered with a soft, reddish hair, and have a mane hanging below the neck, and large, locks of hair at the ankle. Many varieties of the domesticated sheep--that is, all the subjugated species--apparently differ less from their wild namesakes than from each other. The _fat-rumped_ and the _broad-tailed sheep_ are much more extensively diffused than any other, and occupy nearly all the south-eastern part of Europe, Western and Central Asia, and Northern Africa. They are supposed, from various passages in the Pentateuch in which "the fat and the rump" are spoken of in connection with offerings, to be the varieties which were propagated by the patriarchs and their descendants, the Jewish race. They certainly give indisputable evidence of remote and continued subjugation. Their long, pendent, drowsy ears, and the highly artificial posterior developments, are characteristic of no wild or recently domesticated race.
