All day long the watchmen clung to their glaring stations, and Sunday went by without either alarm or excursion. All Sunday--Monday night, they scanned the dark depths of eastward basin, the lone reaches of the valley, the tumbling heights to the west. It was nine in the morning of the second day since the signalling from Squadron Peak when the cry went up from the roof of the office, "Signal smoke south-east!" and every glass at Almy was brought to bear within the minute, and half the garrison lined the lower edge of the mesa, and all men were listening for further tidings, when from the hospital came the stirring shout: "Smoke answer, west!" And there, plainly visible, and not five miles away among the pine-bearded foothills, in little puffs, singly and distinct, thick wreaths of gray-white smoke were sailing straight aloft. The waiting Apache of the Mazatzal was signalling the coming brother from the dark clefts of the Sierra Ancha. One hour later, just as ten was striking on the spiral of the office clock, two sudden shots were heard on the flats to the north-west, and the little herd of horses and mules, not two dozen in all, grazing under cover of the rifles of Sentries 3 and 4, came limping, lumbering in, fast as hoppled feet would permit and without sign of a herdsman. Number Three, a veteran of the war days, let drive with his fifty calibre Springfield, the gun of the day, and sent up a yell for "The Guard!" "Join your companies, men," said the general, in his placid way, whereat most of them went with a rush. "The north side first, Bonner," he added, as the captain came hurrying to his chief. "They've sneaked up on the herd guard, I fancy. Send the picked shots out to the pits."
