The cariboo is essentially a migratory animal. There are two well-defined periods of migration, in the spring and autumn. Throughout the winter it appears also seized with an unconquerable desire to change its residence. One day it may be found feeding quietly through the forests in little bands, and the next, perhaps, all tracks show a general move in a certain direction. The animals join the main herd after a while, and entirely leaving the district, travel toward new feeding-grounds. Though often found in the same woodlands as the moose, they do not enjoy each other's company. In severe winters the cariboos travel to the southernmost limits of their haunts, and even sometimes enter the settlements. Not being aquatic, like the moose, to avoid the flies in summer they ascend the mountain ranges, where they can be free from their attacks. The hunter, however, follows them, and their speed being of no avail among the precipices, many are shot. During most of the year the flesh of the animal is dry and tasteless; but it possesses a layer of fat, two or more inches thick, which is greatly esteemed. This, with the marrow, is pounded together with the dried flesh, and makes the best kind of pemmican--a food of the greatest value to the hunter. The cariboo lives in herds, sometimes only of ten or twenty, but at others consisting of thirty or more individuals. They range across the whole width of the continent, being found in great numbers to the west of the Rocky Mountains, especially at the northern end of British Columbia. Although specifically identical with the reindeer of Europe, it has never yet been trained by Indians or Esquimaux to carry their goods or draw their sleighs, as in Lapland and along the Arctic shores of Asia. The Wapiti, or Canadian Stag. In the wilder parts of the Southern States of the Union, herds of the magnificent Canadian stag or wapiti--popularly called the elk--range amid the woods and over the prairies. Sometimes three or four hundred are found in one herd, always led by an old buck, who exacts from them the strictest obedience--compelling them to halt or move onward as he judges necessary. Now the superb herd of long-horned creatures are seen to wheel to the right or left, now to advance or retreat at the signal he issues.
