sapling down to the stake and fitting it into the notch. It took the weight of both of them to bring the sapling to the ground. If they got the slightest bit off balance, it would spring up again. Once David fell off; the sapling went _swish!_ back into the air, flinging the astonished Phoenix thirty feet up the mountainside. It was not until afternoon, when the sun had turned ruddy and shadows were beginning to stretch dark fingers across the land, that they finished the job. But at last the saplings were set in the notches, the nooses were formed and fastened on. Grass and leaves were strewn over the snares; chips, hewn branches, and other evidences of their work were removed.
