From the wood at the base of the hill came a crackling sound as of something breaking, and then the long crash of a tree falling. He went a little way down the slope and his moccasins made no sound in the grass. Gently pulling aside the bough of a sheltering bush he saw the beavers at work. Already they were measuring for lengths the tree they had cut through at the base with their long, sharp teeth. The creek here received a tributary brook of considerable volume, and the dam erected by the beavers had sent the waters far back in a tiny sheet like a little lake. But as Henry saw, they were going to raise the dam higher, and they were working with the intelligence and energy that belong so peculiarly to the beaver. Four powerful fellows were floating a log in the water, ready to put it into place, and others on the bank were launching another. It was one of the largest beaver colonies he had ever seen, and he watched it with peculiar enjoyment. He killed the beaver now and then--the cap upon his head was made of its skin--but only when it was needful. The industrious animals were safe from his rifle now, and he felt that his wilderness had no more useful people. He looked at them a long time, merely for the pleasure of looking. They showed so much skill, so much quickness and judgment that he was willing to see and learn from them. He felt, in a sense, that they were comrades. He wished them well in their work, and he knew that they would have snug houses, when the next winter came. He left them in their peace, returned to the brow of the hill, and then walked slowly down the other side. He heard a woof, a sound of scrambling, and a black bear, big in frame, but yet lean from the winter, ran from its lair in the bushes, stopped a moment at fifty or sixty yards to look hard at him, and then, wheeling again in frightened flight disappeared among the trees. Henry once more laughed silently. He would not have harmed the bear either. A puffing, panting sound attracted his attention, and, walking farther on, he looked into a glade, in which the grass grew high and thick. He had known from the character of the noise that he would find buffaloes there, and they numbered about a dozen, grazing a while, and then breathing heavily in content. He had seen them in countless herds on the western plains, when he was with Black Cloud and his tribe, but south of the Ohio, owing to the heavy forest, they were found only in small groups, although they were plentiful. The wind was blowing toward him, and standing partially behind a huge oak he watched them. They were the finest and largest inhabitants of his wilderness, splendid creatures, with their leonine manes and huge shoulders, beasts of which any monarch might be proud. He could easily bring down any one of them that he wanted with his rifle, but they were safe from all bullets of his.
