"Altogether I did not find the grizzlies of Yellowstone Park in any degree more tame or less cunning than they are to-day, for example, in the Selkirks. Many of them, it is true, come to the garbage-piles to feed, but these very bears, fifty yards back in the timber, are again as wild as any of them anywhere. At the cañon, the garbage-pile is in a hollow at the foot of rather a steep incline that leads up to the edge of the woods. Bear after bear, coming down the trails that converge toward this point, will stop as he reaches the brink of this declivity, glance downward, turn his head from side to side, and launch himself down hill, with the same air of committing himself to a foreign element that one sees in the upward glance and deep breath of a man launching himself from a diving board. On their return, they invariably halted for a few seconds at the top of the hill, looked around, occasionally shook themselves, and with their first step up the familiar trail, resumed every sign of their habitual caution and alertness. While on the garbage-pile itself, they appear to pay scant attention to the people gathered behind the fairly distant wire fence, but even there, an eye familiar with their actions would note the constant watch they kept on what was going on and the hurried way in which they fed; and, fifty feet from the edge of the surrounding timber, they would at the least scent or sound or sight, bolt as incontinently as in the farthest hills. Grizzlies are no more plentiful around the Park to-day than they were twenty-five years ago in the Bitter Roots, and a hundred yards from the garbage-pile they are no different." Apparently young bears do not inherit fear of a trap, for they are easily trapped. Young bears in captivity sometimes exhibit inherited instincts; they may be pleasurably excited with the scent of food never before seen; and they will sometimes dig down for a hidden root of a kind that their parents ate but which they themselves had never seen. In these cases of digging, they either dug at the right place from scent, or from inherited memory of place. There was nothing on the surface to indicate the presence of buried roots beneath. The young of most animals, wild or tame, make interesting pets. But of all the pets I have known, none equal grizzly cubs for energy, alertness, and individuality. They take naturally to new, unnatural environments. A grizzly cub learns speedily and from the first tries to know everything around him. So all-knowing are his senses and his instincts that the approach of anything new at once attracts him; he stops play and with rare curiosity and concentration tries to understand it. If he solve the mystery he promptly continues play at the point where he left it.
