An hour of this work passed. Whether or not we were yet within the enemy's lines was largely conjecture, for no human eye could pierce the enveloping gloom, and no sound, either of warning or encouragement, reached us as we strained our ears. The Sergeant rode slightly in advance as we toiled up the higher terrace, for our sole dependence as to direction and distance was upon his memory, and even that could scarcely serve for much on such a night as this. I traced his passage upward as best I might, and pressed close after him, guided not so much by sight as by sound,--the occasional rolling of a loosened stone, the rustling of leaves as he touched a bush in passage, the faint clinking of his sabre, and the heavy breathing of his horse,--until at last his long, slender figure rose sufficiently above the dark hill surface to be faintly silhouetted in deeper shadow against the dim reflection of the upper sky. Almost coincidently with this my horse ranged up beside his, where he had drawn rein in evident perplexity. “What is it, Dan?” I questioned cautiously; for all I could feel reasonably assured of just then was that behind any rock or tree in our front there might be crouching a Federal picket. “It's nothing Cap,” he answered quietly, turning his face toward me as he spoke. “I'm just tryin' ter 'member some landmark yereabout ter guide from. Blamed if ever I see such a dark night; it's like bein' inside a pocket, sir, an' I reckon as how it must be nigh onter ten year since I run loose in this yere country as a kid. Thet thar cut-off we took a while back has sort o' confused me, that's a fac', and I don't just know whar I am; but I reckon as how the main ridge road we 're a huntin' after oughter run somewhar out yonder.” He pointed forward into the night. “I supposed from the map it would be found farther back and considerably to the right of us,” I ventured doubtfully. “Never saw no map, Cap,” he returned, with the easy familiarity of a scout on service. “But if I recollect clear, it sure used ter run mighty close ter the east edge. I reckon it ain't changed none to speak of, an' so it'll have ter be somewhere just along thar.” He spoke with such an air of certainty that I felt any controversy useless. “Very well; hand me your rein, and see what you can discover out there on foot. Sitting here isn't apt to mend matters, and we surely cannot afford to cripple our horses among those rocks.” The Sergeant, a gaunt, tireless mountaineer, slipped silently from his saddle, swung his light cavalry carbine from his back to the hollow of his arm, and in another moment was lost to sight in the darkness. A snake could not have slipped away more stealthily. I heard a stone rattle under his foot, a half-suppressed oath, and then the night had completely swallowed him.
