Many wild animals are more interesting per capita than some men. To learn to know our best wild animals is like annexing new territory. It increases our mental and moral resources, and provides a new channel for the disposition of surplus wealth. Like Cupid’s story, they never seem to grow old, and as long as one hoof or horn remains as a going concern, just that long our interest continues in the wearer thereof. The most interesting side of every wild animal is its mind,--what it thinks, and why. First of all, however, we must know the personality of our animal and be able to speak its name as promptly as the politician names his voting acquaintances. To call an antelope a “deer” is to lose a vote. _The Saving of Big Game_ The characteristic features of America’s big game animals are to be treated as natural history. The wasteful slaughter of them is unnatural history. Ever since the days of Daniel Boone, the American pioneers and exploiters of Nature’s resources have most diligently been exterminating our bison, elk, deer, moose, antelope, sheep, and goats. For twenty years we have been toiling to save the American bison from total extinction. Thanks to the efforts of the United States and Canadian Governments, the New York Zoological Society and the American Bison Society, the buffalo now is secure against extinction. Our government now owns and maintains six herds, having a total of about 570 head, and the Canadian Government owns about 1,600 head. Our chief hope is based on the herd in the Montana National Bison Range, now containing 134 head, living in a rich pasture of 29 square miles, capable of supporting 1,000 bison without the purchase of a pound of hay. That herd has risen from 37 head presented in 1909 by the American Bison Society. The Wichita and Wind Cave National Herds were founded by herds drawn from the New York Zoological Park, and presented by the Zoological Society. Excepting for the white-tailed deer and the elk, it is to-day a grave question whether there will be any big game hunting in the United States twenty years hence. _The Prong-Horned Antelope_ It is now painfully certain that nevermore will there be any hunting of the prong-horned antelope in our country. There has been none for several years, but for all that the remaining bands are everywhere (save in two localities) reported as steadily diminishing. Even in the Yellowstone Park the antelope herds are now but little better than stationary. Excepting the goat and musk-ox, the prong-horn is North America’s most exclusively American species of big game. It is so very odd that it occupies a Family all alone. It is the only living hollow-horned ruminant that sheds its horns, every year.
