"No. 4, sir, reports he heard shots—two—way up the valley."

"Good God!" Wren began, then throttled the expletive half spoken. Could they have dared waylay the major—and so close to the post? A moment more and he was hurrying over to his troop quarters; five minutes, and a sergeant and ten men were running with him to the stables; ten, and a dozen horses, swiftly saddled, were being led into the open starlight; fifteen, and they were away at a lunging bronco lope, a twisting column of twos along the sandy road, leaving the garrison to wake and wonder. Three, four, five miles they sped, past Boulder Point, past Rattlesnake Hill, and still no sign of anything amiss, no symptom of night-raiding Apache, for indeed the Apache dreads the dark. Thrice the sergeant had sprung from his horse, lighted a match, and studied the trail. On and on had gone the mules and wagon without apparent break or interruption, until, far beyond the bluff that hid the road from sight of all at Sandy, they had begun the long, tortuous climb of the divide to Cherry Creek. No. 4 might have heard shots, but, if intended for the wagon, they had been harmless. It was long after one when Wren gave the word to put back to the post, and as they remounted and took the homeward trail, they rode for the first five minutes almost directly east, and, as they ascended a little slant of hillside, the sergeant in advance reined suddenly in. "Look there!" said he.

Far over among the rocky heights beyond the valley, hidden from the south from Sandy by precipitous cliffs that served almost as a reflector toward the reservation, a bright blaze had shot suddenly heavenward—a signal fire of the Apache. Some of them, then, were in the heart of that most intractable region, not ten miles northeast of the post, and signaling to their fellows; but the major must have slipped safely through.

Sending his horse to stable with the detachment, Wren had found No. 4 well over toward the east end of his post, almost to the angle with that of No. 5. "Watch well for signal fires or prowlers to-night," he ordered. "Have you seen any?"

"No signal fires, sir," answered the sentry. "Welch, who was on before me, thought he heard shots—"

"I know," answered Wren impatiently. "There was nothing in it. But we did see a signal fire over to the northeast, so they are around us, and some may be creeping close in to see what we're doing, though I doubt it. You've seen nothing?"

"Well, no, sir; we can't see much of anything, it's so dark. But there's a good many of the post people up and moving about, excited, I suppose. There were lights there at the lieutenant's, Mr. Blakely's, a while ago, and—voices." No. 4 pointed to the dark gable end barely forty yards away.

"That's simple enough," said Wren. "People would naturally come up to this end to see what had become of us, why we had gone, etc. They heard of it, I dare say, and some were probably startled."

"Yes, sir, it sounded like—somebody cryin'."

Wren was turning away. "What?" he suddenly asked.
