Fortunately, although it is too late to save many notable animals, the leading nations of the world are rapidly awakening to a proper appreciation of the value and significance of wild life. As a consequence, while the superb herds of game on the limitless plains will vanish, sportsmen and nature lovers, aided by those who appreciate the practical value of wild life as an asset, may work successfully to provide that the wild places shall not be left wholly untenanted. Although Americans have been notably wasteful of wild life, even to the extermination of numerous species of birds and mammals, yet they are now leading the world in efforts to conserve what is left of the original fauna. No civilized people, with the exception of the South African Boers, have been such a nation of hunters as those of the United States. Most hunters have a keen appreciation of nature, and American sportsmen as a class have become ardent supporters of a nation-wide movement for the conservation of wild life. SAVING OUR WILD LIFE Several strong national organizations are doing great service in forwarding the conservation of wild life, as the National Geographic Society, the National Association of Audubon Societies, American Bison Society, Boone and Crockett Club, New York Zoölogical Society, American Game Protective and Propagation Association, Permanent Wild Life Protective Fund, and others. In addition, a large number of unofficial State organizations have been formed to assist in this work. Through the authorization by Congress, the Federal Government is actively engaged in efforts for the protection and increase of our native birds and mammals. This work is done mainly through the Bureau of Biological Survey of the U. S. Department of Agriculture, which is in charge of the several Federal large-game preserves and nearly seventy bird reservations. [Illustration: From a drawing by Charles R. Knight A GROTESQUE CREATURE THAT ONCE LIVED IN THE UNITED STATES (UERTATHERIUM EOCENE, MIDDLE WYOMING) It had six horns on the head and, in some species, two long canine teeth projecting downward from the upper jaw. The feet were somewhat like those of an elephant, but the skull and teeth resemble nothing on earth today.] On the large-game preserves are herds of buffalo, elk, deer, and antelope. The Yellowstone National Park, under the Department of the Interior, is one of the most wonderfully stocked game preserves in the world. In this beautiful tract of forest, lakes, rivers, and mountains live many moose, elk, deer, antelope, mountain sheep, black and grizzly bears, wolves, coyotes, mountain lions, and lynxes.
