[Illustration: AMERICAN BISON OR BUFFALO. (Bison americanus).] The original range of the American Buffalo extended from but little west of the Atlantic coast westward to the Rocky Mountains and from Mexico on the south northward to about the sixty-fifth degree of north latitude. By the trappers the Buffaloes were placed in two classes. Those that frequented the mountain ranges were called Bison. They were seldom seen on the plains, the home of the other class. Their limbs were shorter and stouter and better fitted for a rough country. There existed in former ages two other species entirely distinct from the animal with which we are familiar. They were much larger, possibly as large as an elephant, and were probably associates of the mastodon and the mammoth. A fully adult male Buffalo will measure about nine or ten feet in length from the muzzle to the tail. Its height at the fore quarters is from five to six and one-half feet. The female is much smaller and weighs from seven to eight hundred pounds less than the male, the weight of which averages eighteen hundred pounds. The Buffalo’s massive head, with its short, curved horns which are set far apart on the broad forehead, is connected with the body by a short deep and narrow neck. From the neck the body rises, forming a large hump on the back over the forelegs, which gives the animal an odd and unwieldy appearance. This hump consists of fat and strong muscles which control the movements of the massive head. From the hump the body tapers downward so that the hind quarters are low and narrow. The anterior portion of the body, the forelegs and the head are covered with long hair. On the forehead and back the hair is curly and matted. In the early spring most of the long hair is shed, resulting in a modification of the color of the Buffalo. The new coat is a uniform grayish brown, deepening into black-brown in the mane, which covers the top part of the head, forehead, neck and under surface of the throat.
