true. It was simply that he had become aware of the little continuous sounds of which usually he was unconscious, and they tended to accentuate the hush of the night. He heard his watch ticking in his pocket, the whispered stir of his own breathing, and he was quite certain that he could hear the fevered beat of his own heart in his breast. But then slowly he began to become aware of other sounds, so faint and indistinct that he really could not be sure that he heard them. There was a faint rustle and stir, as of the tops of the pine trees far away. Possibly he heard the wind too, the faintest whisper in the world through the underbrush. And finally, most wonderful of all, he began to hear one by one, over the ridge on which he stood, little whispered sounds of living creatures stirring in the thickets. He knew, just as all mountaineers know, that the wilderness about him was stirring and pulsing with life. Some of the sounds were quite clear—an occasional stir of a pebble or the crack of a twig, and some, like the faintest twitching of leaves in the brush not ten feet distant, could only be guessed at.
