Time passed as the man lay there, time that to another would have been interminable, that to him was apparently unnoted. Gradually, as the full heat of the day approached, the breeze became stronger, set the heat waves dancing to swifter measure, sang audibly in the listener's ears its siren song of prairie and of peace. The broncho, its appetite temporarily satisfied, lay down fair in its tracks, groaned lazily in the action, and shut its eyes. It was the rest time of the wild, and the same instinct appealed to the leader of the distant herd. Down it went where it stood as the pony had done, disappeared absolutely from view. A moment later another followed, and another, and another. It was almost uncanny, there in the fantastic glimmer, that disappearance. In the space of minutes, look where one would, the horizon was blank. Where the herd had been there was nothing, not even a blot. It was as the desert, and the vanished herd a mirage. It was like the far northland tight in the grip of winter, like the ocean at night. It was the Dakota frontier at midday. Again time passed and, motionless as at first, wide eyed, the man lay looking out. The pony was sound asleep now. Its nostrils widened and narrowed rhythmically and it snored at intervals. Save for this and the soft crackle of the grass and the aeolian song of the wind the earth was still; still as death; so still that, indescribably soft as it was immeasurably distant, the man detected of a sudden against it a new sound. But he did not stir. The black eyes looked out motionless as at first. He merely waited a minute, two--and it came again; a bit louder this time, more distinct, unmistakable. This time the listener moved. Deftly, swiftly, he unrolled the gaudy blanket, spread it thin upon the ground, covered it completely with his body. In lieu of a pillow his arms crossed under his head, and, leaning back, the hat brim still shading his eyes, he lay gazing up into the sky, motionless as a prairie boulder.
