The mystery baffled him. More than once that day he went up to the crag and stood and stared futilely at the footprint. Conjecture had license and limitations, too. As the hours wore on he became harassed by the sense of espionage. He was a bold man before the foes he knew, but this idea of inimical lurking, of furtive scrutiny for unknown purposes, preyed upon him. He brooded over it as he sat idle by the fire. Once he went to the door and stared speculatively at the great profile of the cliff. The sky above it was all a lustrous amber, for the early sunset of the shortest days of the year was at hand. The mountains, seen partly above and partly below it, wore a glamourous purple. There were clouds, and from their rifts long divergent lines of light slanted down upon the valley, distinct among their shadows. The sun was not visible--only in the western heavens was a half-veiled effulgence too dazzlingly white to be gazed upon. The ranger shaded his eyes with his hand. No motion, no sound; for the first time in his life the unutterable loneliness of the place impressed him. “'Genie,” he said, suddenly, looking over his shoulder within the cabin, “be you-uns _sure_ ez they war--_folks?_” “I dunno what you mean,” she faltered, her eyes dilated. “They _looked_ like folks.” “I reckon they war,” he said, reassuring himself. “The Lord knows I hope they war.” ***** That night the wind rose. The stars all seemed to have burst from their moorings, and were wildly adrift in the sky. There was a broken tumult of billowy clouds, and the moon tossed hopelessly amongst them, a lunar wreck, sometimes on her beam ends, sometimes half submerged, once more gallantly struggling to the surface, and again sunk. The bare boughs of the trees beat together in a dirgelike monotone. Now and again a leaf went sibilantly whistling past. The wild commotion of the heavens and earth was visible, for the night was not dark. The ranger, standing within the rude stable of unhewn logs, all undaubed, noted how pale were the horizontal bars of gray light alternating with the black logs of the wall. He was giving the mare a feed of corn, but he had not brought his lantern, as was his custom. That mysterious espionage had in some sort shaken his courage, and he felt the obscurity a shield. He had brought, instead, his rifle. The equine form was barely visible among the glooms. Now and then, as the mare noisily munched, she lifted a hoof and struck it upon the ground with a dull thud. How the gusts outside were swirling up the gorge! The pines swayed and sighed. Again the boughs of the chestnut-oak above the roof crashed together. Did a fitful blast stir the door?
