The rise of the high-power, long-range repeating rifle has made the grizzly bear a different animal from what he was in the days of Lewis and Clark. He has learned, _thoroughly,_ the supreme deadliness of man's new weapons, and he knows that he is no longer able to meet men on even terms. Consequently, he runs, he hides, he avoids man, everywhere save in the Yellowstone Park, where he has found out that firearms are prohibited. There he has broken the truce so often that his offenses have had to be met with stern disciplinary measures that have made for the safety of tourists and guides. Once I saw an amusing small incident. Be it known that when a new black bear cub is introduced to a den of its peers, the newcomer shrinks in fright, and cowers, and takes its place right humbly. But species alter cases. Once when we received an eight-months- old grizzly cub we turned it loose in a big den that contained five black bear cubs a year older than itself. But did the grizzly cub cower and shrink? By no manner of means. With head fully erect, it marched calmly to the centre of the den, and with serene confidence gave the other cubs the once-over with an air that plainly said: "_I'm_ a grizzly! I'm here, and I've come to stay. Do I hear any objections?" Quite as if in answer to the challenge, an eighteen-months-old black bear presently sidled up and made a trial blow at the grizzly's head. Instantly the grizzly cub's right arm shot out a well-delivered blow that sent the black one scurrying away in a panic, and perceptibly cleared the atmosphere. That cub had grizzly-bear _courage_ and _confidence;_ that was all. There are a number of American sportsmen who esteem the Cape buffalo as the most aggressive and dangerous wild animal in eastern Africa. He is so courageous and so persistently bold that he is much given to lying in wait for hunters and attacking with real fury. The high grass of his swamps is very helpful to him as a means of defense. In our National Collection of Heads and Horns there is a huge buffalo head (for years the world's highest record) that tells the story of a near tragedy. The brother of Mr. F.H. Barber, of South Africa, fired at the animal, but failed to stop it. His gun jammed, and the charging beast was almost in the act of killing him when F.H. Barber fired without pausing to take aim. His lucky bullet knocked a piece out of the buffalo's left horn, dazed the animal for a moment, and afforded time for the shot that killed the mighty bull. The leopard is usually a vicious beast. When brought to bay it fights with great fury and success. The black leopard is supremely vicious and intractable. Nearly all leopards hate training, and I have seen two or three leopard "acts" that were nerve-racking to witness because of the clear determination of all the animals to kill their trainer at the first opportunity.
