Animated by these thoughts, he held his way up-stream, hoping at every step to reach the gorge from which the flow issued. He would have known this by the sound of the falling water, but, weakening soon, he found he must abandon hope of getting up to it. However, by resting and scrambling up the rocks, he kept on longer than he would have believed possible. Encountering at length, as he struggled upward, a ledge and a clump of bushes, he crawled weakly on hands and knees into it, too spent to struggle farther, stretched himself on the flattened brambles and sank into a heavy sleep. * * * * * He woke in broad daylight. Consciousness returned slowly and he raised himself with pain from his rough couch. His wounds were stiff, and he lay for a long time on his back looking up at the sky. At length he dragged himself to an open space near where he had slept and looked about. He appeared to be near the foot of a mountain quite strange to him, and in rather an exposed place. The shelter that had served him for the night proved worthless in daylight and, following his strongly developed instinct of self-preservation, de Spain started once more up the rocky path of the stream. He clambered a hundred feet above where he had slept before he found a hiding-place. It was at the foot of a tiny waterfall where the brook, striking a ledge of granite, had patiently hollowed out a shallow pool. Beside this a great mass of frost-bitten rock had fallen, and one of the bowlders lay tilted in such a way as to roof in a sort of cave, the entrance to which was not higher than a man's knee. De Spain crawled into this refuge. He conceived that from this high, open ledge he could show a small signal-fire at night, and if it were answered by his enemies he had a semblance of a retreat under the fallen rock, a hunting-knife, and one lone cartridge to protect himself with. A mountain-lion might have to be reckoned with; and if a pursuer should follow him under the rock his only chance would lie in getting hold, after a fight, of the man's loaded revolver or ammunition-belt. Such a hope involved a great deal of confidence, but de Spain was an optimist--most railroad men are.
