In the darkness ahead he could hear the low voices of the men talking to the dogs and encouraging the unresponsive sheep. Overhead were the brilliant, low-swinging stars that gave just enough light to show him the trend of the long, heaving line. For another half-hour there was silence. The sounds of Pedro and his flock became fainter as the two bodies diverged from each other. Now the dark wall of the hogback rose up on Larkin's left; the last of the flock was behind shelter. The going was rough and Pinte chose each step carefully, but the sheep made good progress, because there was no grass to tempt them. After another long space, broken only by the clatter of hard little feet on stone, distant shots rang out, accompanied by faint yells, and Larkin knew that Pedro had met with the first of the Bar T outfit. The sheepman was resigned to losing the hundred, just as cattlemen do not hesitate to cut out and abandon all weak animals on a long drive. It is a loss credited to the ultimate good of the business, but Bud had not consented to this sacrifice if it meant also the sacrifice of the herder. Pedro had, however, with many winks and glintings of teeth, made it clear that he did not expect to depart this life yet a while, hinting mysteriously at certain charms, amulets and saints that made it a business to keep him among the living. Pedro, to Bud's knowledge, had been in numerous seamy affairs before, and had always reappeared, rather the worse for wear, but perfectly sound in all respects. He did not doubt but what the Spaniard would turn up at the cook wagon for breakfast. The sounds of distant conflict continued for perhaps five or ten minutes, at the end of which time perfect silence reigned again. Larkin wondered how many of the animals had been killed, or whether they had been merely scattered--the equivalent of death, for a sheep is unable to find water, and if frightened, will back against a face of rock and starve to death. Another half-hour passed, and now Larkin could see the dim white backs of the herd rising before him as they climbed the steep watercourse. He judged that more than half the flock must be down the precipitous other side, and his heart beat with exultation at the success of Sim's strategy. The plan was to hide the sheep in some little green valley during the day and march them at night until discovered or until the upper range was reached. Suddenly, just as the last of the flock was mounting the ascent, Larkin drew Pinte up short and listened intently. Then he quickly dismounted and placed his ear to the ground only to leap into the saddle again, swing his horse quickly and ride back along the trail. He had heard the unmistakable pounding of feet, and an instant's sickening fear flashed before him the possibility that the Bar T cowboys had discovered the ruse after all; either that or they had extorted the secret of it from Pedro.
