Mr. Rollins remained for some moments in the same attitude, still gazing abstractedly at the rug, and listening to the nervous tramp of his senior officer on the piazza without. Then he slowly and thoughtfully went to his room, where his perturbed spirit was soon soothed in sleep. His conscience being clear and his health perfect, there were no deep cares to keep him tossing on a restless pillow.
To Chester, however, sleep was impossible: he tramped the piazza a full hour before he felt placid enough to go and inspect his guard. The sentries were calling three o'clock, and the wind had died away, as he started on his round. Dark as was the night, he carried no lantern. The main garrison was well lighted by lamps, and the road circling the old fort was broad, smooth, and bordered by a stone coping wall where it skirted the precipitous descent into the river-bottom. As he passed down the plank walk west of the quadrangle wherein lay the old barracks and the stone quarters of the commanding officer and the low one-storied row of bachelor dens, he could not help noting the silence and peace of the night. Not a light was visible at any window as he strode down the line. The challenge of the sentry at the old stone tower sounded unnecessarily sharp and loud, and his response of "Officer of the day" was lower than usual, as though rebuking the unseemly outcry. The guard came scrambling out and formed hurriedly to receive him, but the captain's inspection was of the briefest kind. Barely glancing along the prison corridor to see that the bars were in place, he turned back into the night, and made for the line of posts along the river-bank. The sentry at the high bridge across the gorge, and the next one, well around to the southeast flank, were successively visited and briefly questioned as to their instructions, and then the captain plodded sturdily on until he came to the sharp bend around the outermost angle of the fort and found himself passing behind the quarters of the commanding officer, a substantial two-storied stone house with mansard roof and dormer-windows. The road in the rear was some ten feet below the level of the parade inside the quadrangle, and consequently, as the house faced the parade, what was the ground-floor from that front became the second story at the rear. The kitchen, store-room, and servants' rooms were on this lower stage, and opened upon the road; an outer stairway ran up to the centre door at the back, but at the east and west flanks of the house the stone walls stood without port or window except those above the eaves—the dormers. Light and air in abundance streamed through the broad Venetian windows north and south when light and air were needed. This night, as usual, all was tightly closed below, all darkness aloft as he glanced up at the dormers high above his head. As he did so, his foot struck a sudden and sturdy obstacle; he stumbled and pitched heavily forward, and found himself sprawling at full length upon a ladder lying on the ground almost in the middle of the roadway.
"Damn those painters!" he growled between his set teeth. "They leave their infernal man-traps around in the very hope of catching me, I believe. Now, who but a painter would have left a ladder in such a place as this?"
Rising ruefully and rubbing a bruised knee with his hand, he limped painfully ahead a few steps, until he came to the side-wall of the colonel's house. Here a plank walk passed from the roadway along the western wall until almost on a line with the front piazza, where by a flight of steps it was carried up to the level of the parade. Here he paused a moment to dust off his clothes and rearrange his belt and sword. He stood leaning against the wall and facing the gray stone gable end of the row of old-fashioned quarters that bounded the parade upon the southwest. All was still darkness and silence.
"Confound this sword!" he muttered again: "the thing made rattle and racket enough to wake the dead. Wonder if I disturbed anybody at the colonel's."
As though in answer to his suggestion, there suddenly appeared, high on the blank wall before him, the reflection of a faint light. Had a little night-lamp been turned on in the front room of the upper story? The gleam came from the north window on the side: he saw plainly the shadow of the pretty lace curtains, looped loosely back. Then the shade was gently raised, and there was for an instant the silhouette of a slender hand and wrist, the shadow of a lace-bordered sleeve. Then the light receded, as though carried back across the room, waned, as though slowly extinguished, and the last shadows showed the curtains still looped back, the rolling shade still raised.
"I thought so," he growled. "One tumble like that is enough to wake the Seven Sleepers, let alone a love-sick girl who is probably dreaming over Jerrold's parting words. She is spirited and blue-blooded enough to have more sense, too, that same superb brunette. Ah, Miss Alice, I wonder if you think that fellow's love worth having. It is two hours since he left you—more than that—and here you are awake yet—cannot sleep—want more air, and have to come and raise your shade. No such warm night, either." These were his reflections as he picked up his offending sword and, more slowly and cautiously now, groped his way along the western terrace. He passed the row of bachelor quarters, and was well out beyond the limits of the fort before he came upon the next sentry—"Number Five,"—and recognized, in the stern "Who comes there?" and the sharp rattle of the bayonet as it dropped to the charge, the well-known challenge of Private Leary, one of the oldest and most reliable soldiers in the regiment.
"All right on your post, Leary?" he asked, after having given the countersign.
"All right, I think, sor; though if the captain had asked me that half an hour ago I'd not have said so. It was so dark I couldn't see me hand afore me face, sor; but about half-past two I was walkin' very slow down back of the quarters, whin just close by Loot'nant Jerrold's back gate I seen somethin' movin', and as I come softly along it riz up, an' sure I thought 'twas the loot'nant himself, whin he seemed to catch sight o' me or hear me, and he backed inside the gate an' shut it. I was sure 'twas he, he was so tall and slim like, an' so I niver said a word until I got to thinkin' over it, and then I couldn't spake. Sure if it had been the loot'nant he wouldn't have backed away from a sintry; he'd 'a' come out bold and given the countersign; but I didn't think o' that. It looked like him in the dark, an' 'twas his quarters, an' I thought it was him, until I thought ag'in, and then, sor, I wint back and searched the yard; but there was no one there."
"Hm! Odd thing that, Leary! Why didn't you challenge at first?"
"Sure, sor, he lept inside the fince quick as iver we set eyes on each other. He was bendin' down, and I thought it was one of the hound pups when I first sighted him."
"And he hasn't been around since?"
"No, sor, nor nobody, till the officer of the day came along."
Chester walked away puzzled. Sibley was a most quiet and orderly garrison. Night prowlers had never been heard from, especially over here at the south and southwest fronts. The enlisted men going to or from town passed across the big, high bridge or went at once to their own quarters on the east and north. This southwestern terrace behind the bachelors' row was the most secluded spot on the whole post—so much so that when a fire broke out there among the fuel-heaps one sharp winter's night a year agone it had wellnigh enveloped the whole line before its existence was discovered. Indeed, not until after this occurrence was a sentry posted on that front at all; and, once ordered there, he had so little to do and was so comparatively sure to be undisturbed that the old soldiers eagerly sought the post in preference to any other, and were given it as a peace privilege. For months, relief after relief tramped around the fort and found the terrace post as humdrum and silent as an empty church; but this night "Number Five" leaped suddenly into notoriety.
Instead of going home, Chester kept on across the plateau and took a long walk on the northern side of the reservation, where the quarter-master's stables and corrals were placed. He was affected by a strange unrest. His talk with Rollins had roused the memories of years long gone by—of days when he, too, was young and full of hope and faith, ay, full of love—all lavished on one fair girl who knew it well, but gently, almost entreatingly, repelled
