Could it be that there was a trace of swagger in that long, bony figure as Waldo directed his steps toward the cliff? Perish the thought! Pride in vulgar physical prowess! A long line of Smith-Joneses would have risen in their graves and rent their shrouds at the veriest hint of such an idea. For a long time Waldo walked back and forth along the foot of the cliff, searching for the avenue of escape used by the fugitive of yesternight. A dozen times he passed a well-defined trail that led, winding, up the cliff's face; but Waldo knew nothing of trails--he was looking for a flight of steps or a doorway. Finding neither, he stumbled by accident into the trail; and, although the evident signs that marked it as such revealed nothing to him, yet he followed it upward for the simple reason that it was the only place upon the cliff side where he could find a foothold. Some distance up he came to a narrow cleft in the cliff into which the trail led. Rocks dislodged from above had fallen into it, and, becoming wedged a few feet from the bottom, left only a small cavelike hole, into which Waldo peered. There was nothing visible, but the interior was dark and forbidding. Waldo felt cold and clammy. He began to tremble. Then he turned and looked back toward the forest. The thought of another night spent within sight of that dismal place almost overcame him. No! A thousand times no! Any fate were better than that, and so after several futile efforts he forced his unwilling body through the small aperture. He found himself on a path between two rocky walls--a path that rose before him at a steep angle. At intervals the blue sky was visible above through openings that had not been filled with debris. To another it would have been apparent that the cleft had been kept open by human beings--that it was a thoroughfare which was used, if not frequently, at least sufficiently often to warrant considerable labor having been expended upon it to keep it free from the debris which must be constantly falling from above. Where the path led, or what he expected to find at the other end, Waldo had not the remotest idea. He was not an imaginative youth. But he kept on up the ascent in the hope that at the end he would find the creature which had escaped him the night before. As it had fled for a brief instant across the clearing beneath the moon's soft rays, Waldo had thought that it bore a remarkable resemblance to a human figure; but of that he could not be positive. At last his path broke suddenly into the sunlight. The walls on either side were but little higher than his head, and a moment later he emerged from the cleft onto a broad and beautiful plateau. Before him stretched a wide, grassy plain, and beyond towered a range of mighty hills. Between them and him lay a belt of forest.
