And even as he sat there absorbed in the sweet vision in the moonlight before him, studying the play of her sensitive lips, forgetful for the moment of all else about him, there fell across the glistening boarding at her feet the shadow of a turbaned head, at sight of which she started, with faint, half-suppressed cry of fright; then, as though ashamed, broke into a nervous little laugh. Harris was in an instant on his feet, and whirling, confronted 'Tonio, tall, gaunt, silent, impassive.
"Que quiere?" he demanded, in the blunt vernacular of the service. It annoyed him that subordinate of his should thus appear unseen, unheard, unsummoned, and to her affright. He forgot the noiseless sand, the soft-soled moccasins, the native stealth; forgot at the moment the general's mandate and the orderly's mission. It flashed upon him at 'Tonio's quiet answer, grave, unresentful, and in the Apache tongue.
"My chief called me."
"Pardon me just one moment, Miss Archer. I'll come back at once," said Harris, bending over the still trembling girl. Then, turning sharply and bidding 'Tonio follow, his eyes met those of Willett, smiling affably.
"I'll keep it while you're gone, Hefty," said he, with laughing ease of manner, sliding promptly into the vacated seat. "Now, Miss Archer, if you'll be so good as to go right on where you left off, I'll be all gratitude and attention."
Without answer, Harris stepped lightly over to where the general and Stannard were now deep in one-sided argument over the merits of a war-time leader, known well to men of the Union Army east or west; the general declaiming, the junior listening, unconvinced. It was one point on which they differed widely, one on which the general was apt to dilate when warmed by wine. He had had only moderate aid from Willett in disposing of two bottles of sound old claret, and one was enough to set the garrulous tongue to wagging. He would not cease at sight of Harris, standing silent and respectful before him. Stannard had to interpose and say, "You sent for 'Tonio, sir, as I happened to hear," as indeed they all did, far and near, whereat the veteran turned.
"Bless my soul, boy, so I did! What for, I wonder?"
"To save my going over with night orders for the scouts, I think, sir," said Harris promptly, "and, unless you wish to see him personally, I'll tell him now."
"Must you make so early a start, Harris? It's only thirty miles to the cañon."
"I know, sir, but I need to be at Bennett's before sunrise. Their scouts would see us if we started later. We go on to the cañon after I have examined that neighborhood."
"All right, then. Buckets will issue rations at once. Start when you think best. But now, Stannard, see here; if he was such a stayer and so energetic in Virginia, how do you account for——"
But Harris had saluted and turned away, 'Tonio at his heels. As they passed the end of the veranda, where sat Lilian and her listener, Harris noted that the latter had drawn his chair much closer than he had dared, and was bending forward until the handsome dark head was almost over the fair hand toying with the guitar that lay idly in her lap. The modern vernacular for the successful squire of dames was then unknown. The girl, who had been leaning forward, all chat and animation when Harris sat there, now lay dreamily back in the rude but easy chair, her eyelids drooping, her long lashes sweeping the soft cheek, listening, drinking in the murmurous flow of Willett's almost inaudible words, and the stern young face of his classmate hardened in the moonlight, for Harris had seen and heard before. Briefly he gave his instructions to the silent Apache and closed with the sign, "I have spoken. That is all."
But 'Tonio did not stir. Something, possibly, in Willett's devotional attitude vaguely troubled the girl, and, edging back in her chair, she had lifted a little slippered foot from the floor. The general at the moment was talking loud enough to drown other sounds about him. The aide-de-camp, his dark eyes glowing and riveted on those of the fair face so near him, seemed deaf to everything but his own eloquence. But the Indian had placed one hand on his young officer's wrist, and with the other stood pointing at some object coiled underneath Lilian's chair, not half an arm's length from the little foot that dangled in its silken stocking but a hand's-breadth from the floor. At that moment Willett bent impressively, still nearer, and instinctively Lilian moved a hand as though about to edge farther away. It was at this very instant that Harris spoke, his voice, absolutely calm, even to the semblance of a drawl, but every word told clear, distinct, and, in spite of its courtesy, commanding, compelling.
"Miss Archer and—ah—Willett, be good enough to sit perfectly still a moment. Don't—move—a muscle!"
Even the general, for a wonder, had ceased—for breath, perhaps—and sat speechless and startled, for noiseless and stealthy as a cat, with long strides, 'Tonio had skirted the edge of the veranda, and with agile spring was at the back of Lilian's chair. There he swooped instantly. There was sound of strident, rasping sk-r-r-r-rr: then a lightning snap, as of a whip. Something black and writhing went flying into the sand, and then squirming blindly away, and 'Tonio straightened to his full height, and without a word strode from the veranda.
"In God's name, what was that?" cried the general, springing from his chair and hastening to his daughter's side.
"Nothing but a snake, sir," said Harris quietly, strolling toward them. "That one's done for, anyhow!"
CHAPTER IV.
An hour later the lights were out among the barracks, and the silence of the summerlike winter's night had settled on the garrison. Over at the Mess and office buildings all was darkness. Along the log and adobe façade of the officers' quarters, from occasional open doorways the gleam of lantern was thrown across the wooden verandas. The moonbeams flooded the sandy parade and the rough-hewn roofs and walls with tender, silvery radiance that put to shame the twinkling lights, down at the store on the lower flats, and the bleary eye of the big, triangular, glass-faced, iron-bound cresset at the log guard-house, perched at the edge of the mesa. Afar off, through dim vistas of the valley, the silver ribbon of the stream wound and twisted among the willows, but the heights, as a rule, were wrapped in the shadows of their own pines. A game of goodly proportion was going on down at the card room, a brace of ranchmen and prospectors, a venturesome "sub" and the "contract doctor" making up the party, but the general, his household and near neighbors had retired or were retiring for the night. Only the guard and the "owls" were "on deck." Army folk in those days and regions had a way of turning out at dawn for the cool of the morning, turning in at taps for the needed six hours' beauty sleep, lunching lightly at noon, snoozing drowsily an hour or two, then after tub and fresh linen, venturing forth, those who had to, for the afternoon duties. All social enjoyment, as a rule, began when the sun could not see, but had dropped back of the screen of the mountains.
But there was still faint stir at the camp of the scouts, out beyond the corrals. Rations had been drawn at tattoo, and a limited portion issued to the lithe, swarthy fellows, squatted in semicircle in front of their chief, patiently awaiting their share, no man of their number opening so much as the end of a package,
