Although endowed with such strength, and powers of destruction, the grisly bear is not disposed to begin the attack. Mr. Drummond, a later traveller, states, that, in his excursions over the Rocky Mountains, he had frequent opportunity of observing the manners of these animals; and it often happened, that in turning the point of a rock, or sharp angle of a valley, he came suddenly upon one or more of them. On such occasions they reared on their hind-legs, and made a loud noise like a person breathing quick, but much harsher. He kept his ground, without attempting to molest them; and they on their part, after attentively regarding him for some time, generally wheeled round, and galloped off: though, from their known disposition, there is little doubt but he would have been torn in pieces, had he lost his presence of mind and attempted to fly. When he discovered them at a distance, he often frightened them away by beating on a large tin box in which he carried his specimens of plants. THE BLACK BEAR. "The black bear, common in the United States, is scarcely more than half the size of the grisly bear. Its favorite food is berries of various kinds; but, when these are not to be procured, it lives upon roots, insects, fish, eggs, and such birds and quadrupeds as it can surprise. It passes the winter in a torpid state, selecting a spot for its den under a fallen tree, and, having scratched away a portion of the soil, retires to the place at the commencement of a snow storm, when the snow soon furnishes it with a close, warm covering. Its breath makes a small opening in the den, and the quantity of hoar-frost which gathers round the hole serves to betray its retreat to the hunter. In more southern districts, where the timber is of larger size, bears often shelter themselves in hollow trees." BUFFALOES.
