He was a very quiet, self-possessed sort of man, sitting a moment on top of the wall to sound the damp darkness for warnings of the dangers it might conceal. but the plummet of his hearing brought nothing to him save the moaning of wind through invisible trees and the rustling of leaves on swaying branches. a heavy fog drifted and drove before the wind, and though he could not see this fog, the wet of it blew upon his face, and the wall on which he sat was wet. without noise he had climbed to the top of the wall from the outside, and without noise he dropped to the ground on the inside. from his pocket he drew an electric night-stick, but he did not use it. dark as the way was, he was not anxious for light. carrying the night-stick in his hand, his finger on the button, he advanced through the darkness. the ground was velvety and springy to his feet, being carpeted with dead pine-needles and leaves and mold which evidently had been undisturbed for years. leaves and branches brushed against his body, but so dark was it that he could not avoid them. soon he walked with his hand stretched out gropingly before him, and more than once the hand fetched up against the solid trunks of massive trees. all about him he knew were these trees; he sensed the loom of them everywhere; and he experienced a strange feeling of microscopic smallness in the midst of great bulks leaning toward him to crush him. beyond, he knew, was the house, and he expected to find some trail or winding path that would lead easily to it. once, he found himself trapped. on every side he groped against trees and branches, or blundered into thickets of underbrush, until there seemed no way out. then he turned on his light, circumspectly, directing its rays to the ground at his feet. slowly and carefully he moved it about him, the white brightness showing in sharp detail all the obstacles to his progress. he saw an opening between huge-trunked trees, and advanced through it, putting out the light and treading on dry footing as yet protected from the drip of the fog by the dense foliage overhead. his sense of direction was good, and he knew he was going toward the house. and then the thing happened—the thing unthinkable and unexpected. his descending foot came down upon something that was soft and alive, and that arose with a snort under the weight of his body. he sprang clear, and crouched for another spring, anywhere, tense and expectant, keyed for the onslaught of the unknown. he waited a moment, wondering what manner of animal it was that had arisen from under his foot and that now made no sound nor movement and that must be crouching and waiting just as tensely and expectantly as he. the strain became unbearable. holding the night-stick before him, he pressed the button, saw, and screamed aloud in terror. he was prepared for anything, from a frightened calf or fawn to a belligerent lion, but he was not prepared for what he saw. in that instant his tiny searchlight, sharp and white, had shown him what a thousand years would not enable him to forget—a man, huge and blond, yellow-haired and yellow-bearded, naked except for soft-tanned moccasins and what seemed a goat-skin about his middle. arms and legs were bare, as were his shoulders and most of his chest. the skin was smooth and hairless, but browned by sun and wind, while under it heavy muscles were knotted like fat snakes…practically in the instant he saw all this… [h]e bounded up and away…he did not wait for more, but ran.
