The American bison, or buffalo, is a close relative of the larger bison which once inhabited Europe and survives in limited numbers in certain game preserves of Poland and the Caucasus. The size, dark shaggy coat, great head, and high arched shoulders of our bison give them a unique individuality among American big game. They once roamed in vast numbers over a broad territory, extending from Great Slave Lake, Canada, south to southern New Mexico, and from Pennsylvania and eastern Georgia to Arizona and northern Nevada. It is thus evident that they were at home in the forested country east of the Mississippi River, as well as on the treeless plains of the West. In the northern part of their range they are larger and darker than elsewhere and form a local geographic race called the wood buffalo. [Illustration: MOOSE] [Illustration: AMERICAN BISON, OR BUFFALO] Originally buffalo were enormously abundant in America, and it has been variously estimated that when the continent was first discovered their numbers were from 30,000,000 to 60,000,000. With the settlement of eastern America, they gradually retreated across the Mississippi River, but continued to exist in great but rapidly diminishing numbers on the Great Plains up to within the last fifty years. The crossing of their range by the first transcontinental railroad quickly brought the remaining herds to an end. In 1870 there were still about 5,500,000 head on the plains, but these were so wastefully slaughtered for their hides that in 1895 only about 800 remained. The depletion of the herds was so startling that sportsmen and nature lovers awoke to the danger of the immediate extermination of these splendid animals; the American Bison Society was organized and the surviving buffalo were saved. Although the bison usually has but a single calf a year, these are so hardy and do so well in fenced preserves, and even in the closer confinement of small parks, that their number has now increased to approximately 4,000, about equally divided between the United States and Canada. In the district south of Artillery Lake, northern Canada, a few hundred individuals, remnants of the wild stock of that region, survive and are increasing under the wise protection of the Canadian Government. The only other herd still existing on its original ground is that in Yellowstone National Park. Experiments have been made in crossing buffalo with certain breeds of domestic cattle for the purpose of establishing a new and hardier variety of stock for the Western ranges. These have not proved successful, largely owing to the lack of fertility in the hybrid, which has been called the “cattalo.”
