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 him. Her heart was wrapped up in another, the Adonis of his day in the gay old seaboard garrison. She was a soldier's child, barrack-born, simply taught, knowing little of the vice and temptations, the follies and the frauds, of the whirling life of civilization. A good and gentle mother had reared her and been called hence. Her father, an officer whose sabre-arm was left at Molino del Rey, and whose heart was crushed when the loving wife was taken from him, turned to the child who so resembled her, and centred there all his remaining love and life. He welcomed Chester to his home, and tacitly favored his suit, but in his blindness never saw how a few moonlit strolls on the old moss-grown parapet, a few evening dances in the casemates with handsome, wooing, winning Will Forrester, had done their work. She gave him all the wild, enthusiastic, worshipping love of her girlish heart just about the time Captain and Mrs. Maynard came back from leave, and then he grew cold and negligent there, but lived at Maynard's fireside; and one day there came a sensation,—a tragedy,—and Mrs. Maynard went away, and died abroad, and a shocked and broken-hearted girl hid her face from all and pined at home, and Mr. Forrester's resignation was sent from—no one knew just where, and no one would have cared to know, except Maynard. He would have followed him, pistol in hand, but Forrester gave him no chance. Years afterwards Chester again sought her and offered her his love and his name. It was useless, she told him, sadly. She lived only for her father now, and would never leave him till he died, and then—she prayed she might go too. Memories like this will come up at such times in these same "still watches of the night." Chester was in a moody frame of mind when about half an hour later he came back past the guard-house. The sergeant was standing near the lighted entrance, and the captain called him:

"There's a ladder lying back of the colonel's quarters on the roadway. Some of those painters left it, I suppose. It's a wonder some of the reliefs have not broken their necks over it going around to-night. Let the next one pick it up and move it out of the way. Hasn't it been reported?"

"Not to me, sir. Corporal Schreiber has command of this relief, and he has said nothing about it. Here he is, sir."

"Didn't you see it or stumble over it when posting your relief, corporal?" asked Chester.

"No indeed, sir. I—I think the captain must have been mistaken in thinking it a ladder. We would surely have struck it if it had been."

"No mistake at all, corporal. I lifted it. It is a long, heavy ladder,—over twenty feet, I should say."

"There is such a ladder back there, captain," said the sergeant, "but it always hangs on the fence just behind the young officers' quarters,—Bachelors' Row, sir, I mean."

"And that ladder was there an hour ago when I went my
