First of all she made a deep cut through the bark which circled the trunk as far from the ground as she could conveniently reach. Some three or four inches lower she cut a second ring, and then, slowly and surely, dug out the wood from between, splinter by splinter, with those sharp teeth of hers. The day wore on, and still she worked. Father Beaver offered to help her; each time he came she sent him back. It was growing dusk; Phil saw that now the trunk of the tree between the cuts went in like a lady's waist. Each time that Mother Beaver drew out a splinter this "waist" became more slender still; a very little further, and the tree would have been cut right through, but Mother Beaver knew when to stop. "Come away," she cried quickly to Phil; "at the next gust of wind that tree will fall, and only foolish creatures run knowingly into danger. I should be crushed beneath it if I drew out another splinter. Some of our family have already met their deaths that way; they were too impulsive, and did not stop to think." The Night Wind came singing through the forest, and the branches of the big tree quivered; with a low groan it crashed to earth, and Phil found that it took all his new strength to drag the heavy mass down to the bank. "I s'pose you'll all take a rest now," he said persuasively, for he was longing to hear about Father Beaver's encounter with the Otter, and thought that he would not mind trying some of that maple syrup himself. But the Beavers were only just getting into their work, as they told him gaily, though he, of course, might take a nap. They were still at it when he awoke next morning. "We shall go on until not a tree on this spot is left standing," Mother Beaver declared, cheerfully; and he quite believed her. By the afternoon his arms began to ache, and the Beavers had found him so useful that one of the elders of the colony had remarked that he should have nothing to say against it if he wished to stay with them altogether. Phil thought this very kind of him; but, much as he liked the Beavers, there were many other animals that he wanted to meet. Perhaps Mother Beaver guessed something of this, for she told him pleasantly to go off to the woods. "You'll work all the better to-morrow," she said; and Father Beaver flapped his tail by way of dismissal.
