hen Mr. Blakely left the post that afternoon he went afoot. When he returned, just after the sounding of retreat, he came in saddle. Purposely he avoided the road that led in front of the long line of officers' quarters and chose instead the water-wagon track along the rear. People among the laundresses' quarters, south of the mesa on which stood the quadrangular inclosure of Camp Sandy, eyed him curiously as he ambled through on his borrowed pony; but he looked neither to right nor left and hurried on in obvious discomposure. He was looking pale and very tired, said the saddler sergeant's wife, an hour later, when all the garrison was agog with the story of Wren's mad assault. He never seemed to see the two or three soldiers, men of family, who rose and saluted as he passed, and not an officer in the regiment was more exact or scrupulous in his recognition of such soldier courtesy as Blakely had ever been. They wondered, therefore, at his strange abstraction. They wondered more, looking after him, when, just as his stumbling pony reached the crest, the rider reined him in and halted short in evident embarrassment. They could not see what he saw—two young girls in gossamer gowns of white, with arms entwining each other's waists, their backs toward him, slowly pacing northward up the mesa and to the right of the road. Some old croquet arches, balls, and mallets lay scattered about, long since abandoned to dry rot and disuse, and, so absorbed were the damsels in their confidential chat,—bubbling over, too, with merry laughter,—they gave no heed to these until one, the taller of the pair, catching her slippered foot in the stiff, unyielding wire, plunged forward and fell, nearly dragging her companion with her. Blakely, who had hung back, drove his barbless heels into the pony's flanks, sent him lurching forward, and in less than no time was out of saddle and aiding her to rise, laughing so hard she, for a moment, could not speak or thank him. Save to flowing skirt, there was not the faintest damage, yet his eyes, his voice, his almost tremulous touch were all suggestive of deep concern, before, once more mounting, he raised his broad-brimmed hat and bade them reluctant good-night. Kate Sanders ran scurrying home an instant later, but Angela's big and shining eyes followed him every inch of the way until he once more dismounted at the upper end of the row and, looking back, saw her and waved his hat, whereat she ran, blushing, smiling, and not a little wondering, flustered and happy, into the gallery of their own quarters and the immediate presence of her father. Blakely, meanwhile, had summoned his servant:

"Take this pony at once to Mr. Hart," said he, "and say I'll be back again as soon as I've seen the commanding officer."

When Downs, the messenger, returned to the house about half an hour later, it was to find his master prostrate and bleeding on the bed in his room, Dr. Graham and the hospital attendant working over him, the major and certain of his officers, with gloomy faces and muttering tongues, conferring on the piazza in front, and one of the lieutenant's precious cases of bugs and butterflies a wreck of shattered glass. More than half the officers of the post were present. A bevy of women and girls had gathered in the dusk some distance down the row. The wondering Milesian whispered inquiry of silent soldiers lingering about the house, but the gruff voice of Sergeant Clancy bade them go about their business. Not until nearly an hour later was it generally known that Captain Wren had been escorted to his quarters by the post adjutant and ordered to remain therein in close arrest.

If some older and more experienced officer than Duane had been there perhaps the matter would not have proved so tragic, but the latter was utterly unstrung by Wren's furious attack and the unlooked-for result. Without warning of any kind, the burly Scot had launched his big fist straight at Blakely's jaw, and sent the slender, still fever-weakened form crashing through a case of specimens, reducing it to splinters that cruelly cut and tore the bruised and senseless face. A corporal of the guard, marching his relief in rear of the quarters at the moment, every door and window being open, heard the crash, the wild cry for help, rushed in, with his men at his heels, and found the captain standing stunned and ghastly, with the sweat starting from his brow, staring down at the result of his fearful work. From the front Captain Sanders and his amazed lieutenant came hurrying. Together they lifted the stricken and bleeding man to his bed in the back room and started a soldier for the doctor on the run. The sight of this man, speeding down the row, bombarded all the way with questions he could not stop to answer, startled every soul along that westward-facing front, and sent men and women streaming up the line toward Blakely's quarters at the north end. The doctor fairly brushed them from his path and Major Plume had no easy task persuading the tearful, pallid groups of army wives and daughters to retire to the neighboring quarters. Janet Wren alone refused point-blank. She would not go without first seeing her brother. It was she who took the arm of the awed, bewildered, shame-and conscience-stricken man and led him, with bowed and humbled head, the adjutant aiding on the other side, back to the door he had so sternly closed upon his only child, and that now as summarily shut on him. Dr. Graham had pronounced the young officer's injuries serious, and the post commander was angry to the very core.

One woman there was who, with others, had aimlessly hastened up the line, and who seemed now verging on hysterics—the major's wife. It was Mrs. Graham who rebukefully sent her own braw young brood scurrying homeward through the gathering dusk, and then possessed herself of Mrs. Plume. "The shock has unnerved you," she charitably, soothingly whispered: "Come away with me," but the major's wife refused to go. Hart, the big post trader, had just reached the spot, driving up in his light buckboard. His usually jovial face was full of sympathy and trouble. He could not believe the news, he said. Mr. Blakely had been with him so short a time beforehand and was coming down again at once, so Downs, the striker, told him, when some soldier ran in to say the lieutenant had been half killed by Captain Wren. Plume heard him talking and came down the low steps to meet and confer with him, while the others, men and women, listened eagerly, expectant of developments. Then Hart became visibly embarrassed. Yes, Mr. Blakely had come up from below and begged the loan of a pony, saying he must get to the post at once to see Major Plume. Hadn't he seen the major? No! Then Hart's embarrassment increased. Yes, something had happened. Blakely had told him, and in fact they—he—all of them had something very important on hand. He didn't know what to do now, with Mr. Blakely unable to speak, and, to the manifest disappointment of the swift-gathering group, Hart finally begged the major to step aside with him a moment and he would tell him what he knew. All eyes followed them, then followed the major as he came hurrying back with heightened color and went straight to Dr. Graham at the sufferer's side. "Can I speak with him? Is he well enough to answer a question or two?" he asked, and the doctor shook his head. "Then, by the Lord, I'll have to wire to Prescott!" said Plume, and left the room at once. "What is it?" feebly queried the patient, now half-conscious. But the doctor answered only "Hush! No talking now, Mr. Blakely," and bade the others leave the room and let him get to sleep.

But tattoo had not sounded that still and starlit evening when a strange story was in circulation about the post, brought up from the trader's store by pack-train hands who said they were there when Mr. Blakely came in and asked for Hart—"wanted him right away, bad," was the way they put it. Then it transpired that Mr. Blakely had found no sport at bug-hunting and had fallen into a doze while waiting for winged insects, and when he woke it was to make a startling discovery—his beautiful Geneva watch had disappeared from one pocket and a flat note case, carried in an inner breast pocket of his white duck blouse, and containing about one hundred dollars, was also gone. Some vagrant soldier, possibly, or some "hard-luck outfit" of prospectors, probably, had come upon him sleeping, and had made way with his few valuables. Two soldiers had been down stream, fishing for what they called Tonto trout, but they were looked up instantly and proved to be men above suspicion. Two prospectors had been at Hart's, nooning, and had ridden off down stream toward three o'clock. There was a clew worth following, and certain hangers-on about the trader's, "layin' fer a job," had casually hinted at the prospect of a game down at Snicker's—a ranch five miles below. Here, too, was something worth investigating. If Blakely had been robbed, as now seemed more than likely, Camp Sandy felt that the perpetrator must still be close at hand and of the packer or prospector class.

But before the ranks were broken, after the roll-call, then invariably held at half-past nine, Hart came driving back in a buckboard, with a lantern and a passenger, the latter one of the keenest trailers among the sergeants of Captain Sanders' troop, and Sanders was with the major as the man sprang from the wagon and stood at salute.

"Found anything, sergeant?" asked Plume.

"Not a boot track, sir, but the lieutenant's own."

"No tracks at all—in that soft sand!" exclaimed the major, disappointed and unbelieving. His wife had come slowly forward from within doors, and, bending slightly toward them, stood listening.

"No boot tracks, sir. There's others though—Tonto moccasins!"

Plume stood bewildered. "By Jove! I never thought of that!" said he, turning presently on his second troop commander. "But who ever heard of Apaches taking a man's watch and leaving—him?"

"If the major will look," said the sergeant, quietly producing a scouting notebook such as was then issued by the engineer department, "I measured 'em and made rough copies here. There was two, sir. Both came, both went, by the path through the willows up stream. We didn't have time to follow. One is longer and slimmer than the other. If I may make so bold, sir, I'd have a guard down there to-night to keep people away; otherwise the tracks may be spoiled before morning."

"Take three men and go yourself," said the major promptly. "See anything of any of the lieutenant's property? Mr. Hart told you, didn't he?" Plume was studying the sergeant's pencil sketches, by the light of the trader's lantern, as he spoke, a curious, puzzled look on his soldierly face.

"Saw where the box had lain in the sand, sir, but no trace of the net," and Sergeant Shannon was thinking less of these matters than of his sketches. There was something he thought the major ought to see, and presently he saw.

"Why, sergeant, these may be Tonto moccasin tracks, but not grown men's. They are mere boys, aren't they?"

"Mere girls, sir."

There was a sound of rustling skirts upon the bare piazza. Plume glanced impatiently over his shoulder. Mrs. Plume had vanished into the unlighted hallway.

"That would account for their taking the net," said he thoughtfully, "but what on earth would the guileless Tonto maiden do with a watch or with greenbacks? They wouldn't dare show with them at the agency! How far did you follow the tracks?"

"Only a rod or two. Once in the willows they can't well quit them till they reach the shallows above the pool, sir. We can guard there to-night and begin trailing at dawn."

"So be it then!" and presently the conference closed.

Seated on the adjoining gallery, alone and in darkness, stricken and sorrowing, a woman had been silently observant of the meeting, and had heard occasional snatches of the talk. Presently she rose; softly entered the house and listened at a closed door on the northward side—Captain Wren's own room. An hour previous, tortured between his own thoughts and her well-meant, but unwelcome efforts to cheer him, he had begged to be left alone, and had closed his door against all comers.

Now, she as softly ascended the narrow stairway and paused for a moment at another door, also closed. Listening a while, she knocked, timidly, hesitatingly, but no answer came. After a while, noiselessly, she turned the knob and entered.

A dim light was burning on a little table by the white bedside. A long, slim figure, white-robed and in all the abandon of girlish grief, was lying, face downward, on the bed. Tangled masses of hair concealed much of the neck and shoulders, but, bending over, Miss Wren could partially see the flushed and tear-wet cheek pillowed on one slender white arm. Exhausted by long weeping, Angela at last had dropped to sleep, but the little hand that peeped from under the thick, tumbling tresses still clung to an odd and unfamiliar object—something the older woman had seen only at a distance before—something she gazed at in startled fascination this strange and solemn night—a slender, long-handled butterfly net of filmy gauze.
