Glen had been conscious, ever since reaching his haven, of a dull, distant roar coming up from the cañon below him; and now, after an hour of scrambling, climbing, slipping, but still managing to keep out of the water, he discovered the fall that he had anticipated, and found himself on its brink. It was a direct plunge of a hundred feet, and the body of water very nearly occupied the whole of a narrow chasm between two cliffs similar to those at the outlet of the lake. A few feet of the rocky dam, where Glen stood, were bare of water; but its face fell away as steep and smooth as that over which the stream took its plunge. Only, in the angle formed by it and the side of the cañon, a mass of débris had collected that reached about half-way up to where Glen stood, or to within fifty feet of the brink. On it grew a few stunted trees, the first vegetation he had seen since taking his slide. Below that place the way seemed more open, and as though it might be possible to traverse. But how should he get down? He dared not leap; he could not fly. But he still had the lariat. It was forty feet long. If he could only fasten it where he stood, he might slide down its length and then drop.
