His jet-black horns are only about five or six inches in length, and the long, white hair with which he is covered obscures the expression of his limbs.

I have never yet seen a single specimen in the Sierra, though possibly a few flocks may have lived on Mount Shasta a comparatively short time ago.
The ranges of these two mountaineers are pretty distinct, and they see but little of each other; the sheep being restricted mostly to the dry, inland mountains; the goat or chamois to the wet, snowy glacier-laden mountains of the northwest coast of the continent in Oregon, Washington, British Columbia, and Alaska.

Probably more than 200 dwell on the icy, volcanic cone of Mount Rainier; and while I was exploring the glaciers of Alaska I saw flocks of these admirable mountaineers nearly every day, and often followed their trails through the mazes of bewildering crevasses, in which they are excellent guides.
Three species of deer are found in California,--the black-tailed, white-tailed, and mule deer.

The first mentioned (_Cervus Columbianus_) is by far the most abundant, and occasionally meets the sheep during the summer on high glacier meadows, and along the edge of the timber line; but being a forest animal, seeking shelter and rearing its young in dense thickets, it seldom visits the wild sheep in its higher homes.
The antelope, though not a mountaineer, is occasionally met in winter by the sheep while feeding along the edges of the sage-plains and bare volcanic hills to the east of the Sierra.

So also is the mule deer, which is almost restricted in its range to this eastern region.
