But Bill Breakstone was a man watchful, alert, a sentinel full of strength and resolution. He would not sleep, no, not he, not while so much depended upon him, yet the song among the leaves was growing sweeter and gentler all the time. He had never felt such a soothing quiet in all his life. The complete relaxation after so much danger and tension was at hand, and it was hard for one to watch the forest and be troubled about foes who would no longer come. Yet he would remain awake and keep faithful guard, and, as he murmured his resolution for the fifth time, his drooping eyelids shut down entirely, and he slept as soundly as the boy who lay by his side, his chest rising and falling as he breathed long and regularly. Phil Bedford and Bill Breakstone slept all that afternoon. It was a mighty sleep, the great sleep following complete mental and physical exhaustion, the sleep that comes at such times to strong, healthy beings, in whom the co-ordination of brain, muscle, and nerve is complete. By some unconscious method of keeping time they breathed in perfect unison, and the gentle wind, which all the while was blowing through the leaves, kept time with them, too. Thus the evening shortened. Hour by hour dropped into the sandglass of time. The two, rivals of the ancient seven of famous memory, slept on. Both the wolf and the puma, driven by curiosity, came back. They crept a little nearer than before, but not too near. They felt instinctively that the mighty sleepers, mightily as they slept, could yet be awakened, and the smell of man contained a quality that was terrifying. So they went away, and, an hour after they were gone, the same two Comanches, naked to the waist, painted hideously in many symbols and decorations, and savage and cruel of countenance, came back in their places. But Bill Breakstone and Phil lay safe in the leaves under the bank, sleeping peacefully without dreams. So far as the Comanches were concerned, they were a thousand miles away, and presently the two warriors disappeared again in the depths of the forest, this time not to return. Time went on. The two slept the great sleep so quietly that all the normal life of the woods about them was resumed. Woodpeckers drummed upon the sides of the hollow trees, a red bird in a flash of flame shot among the boughs, quail scuttled in the grass, and a rabbit hopped near. Midafternoon of a cloudless day came. The sun shot down its most brilliant beams, the whole forest was luminous with light. The Comanches ceased their search, confident that the fugitives were gone now beyond their overtaking, and returned to their villages and other enterprises, but Breakstone and Phil slept their great sleep.
