Captain Parrol Hartroy stood at the advanced post of his picket-guard, talking in low tones with the sentinel. This post was on a turnpike which bisected the captain's camp, a half-mile in rear, though the camp was not in sight from that point. The officer was apparently giving the soldier certain instructions--was perhaps merely inquiring if all were quiet in front. As the two stood talking a man approached them from the direction of the camp, carelessly whistling, and was promptly halted by the soldier. He was evidently a civilian--a tall person, coarsely clad in the home-made stuff of yellow gray, called "butternut," which was men's only wear in the latter days of the Confederacy. On his head was a slouch felt hat, once white, from beneath which hung masses of uneven hair, seemingly unacquainted with either scissors or comb. The man's face was rather striking; a broad forehead, high nose, and thin cheeks, the mouth invisible in the full dark beard, which seemed as neglected as the hair. The eyes were large and had that steadiness and fixity of attention which so frequently mark a considering intelligence and a will not easily turned from its purpose--so say those physiognomists who have that kind of eyes. On the whole, this was a man whom one would be likely to observe and be observed by. He carried a walking-stick freshly cut from the forest and his ailing cowskin boots were white with dust. "Show your pass," said the Federal soldier, a trifle more imperiously perhaps than he would have thought necessary if he had not been under the eye of his commander, who with folded arms looked on from the roadside. "'Lowed you'd rec'lect me, Gineral," said the wayfarer tranquilly, while producing the paper from the pocket of his coat. There was something in his tone--perhaps a faint suggestion of irony--which made his elevation of his obstructor to exalted rank less agreeable to that worthy warrior than promotion is commonly found to be. "You-all have to be purty pertickler, I reckon," he added, in a more conciliatory tone, as if in half-apology for being halted. Having read the pass, with his rifle resting on the ground, the soldier handed the document back without a word, shouldered his weapon, and returned to his commander. The civilian passed on in the middle of the road, and when he had penetrated the circumjacent Confederacy a few yards resumed his whistling and was soon out of sight beyond an angle in the road, which at that point entered a thin forest. Suddenly the officer undid his arms from his breast, drew a revolver from his belt and sprang forward at a run in the same direction, leaving his sentinel in gaping astonishment at his post. After making to the various visible forms of nature a solemn promise to be damned, that gentleman resumed the air of stolidity which is supposed to be appropriate to a state of alert military attention.
