scraping others of the pursuing horde with it. A chorus of rage came up from below him, but Waldo had not even turned his head to learn of his temporary good fortune. Up, ever up he sped, until at length he stood upon the topmost ledge, facing an overhanging wall of blank rock that towered another twenty-five feet above him to the summit of the bluff. Time and again he leaped futilely against the smooth surface, tearing at it with his nails in a mad endeavor to climb still higher.
