Bud and Slim, Nort and Snake, and Dick and Yellin' Kid were assigned to divide the night among them working as partners in the order named. The others were to be allowed to roll up and get what sleep they could, Bud and Slim taking the first watch. That passed off uneventfully, as did the vigil of Nort and Snake, nothing more important occurring than the distant howls of the coyotes. When it was the turn of Dick and Yellin' Kid they rolled out, albeit sleepy and tired, to stand guard until morning, when the trail would again be taken up. "Zimmy! But it's chilly!" said Kid in a low voice, as lie tossed some wood on the fire and wrapped his blanket more closely about him. "Yes, it always is just before sunrise," added Dick. "I wonder what we'll find after daylight?" "I hope we find that ornery bunch!" murmured Yellin' Kid, keeping down his voice so as not to awaken the sleepers. "So do I," said Dick. Then they sat about the fire, occasionally strolling around the improvised camp, to make sure that none of their enemies were creeping up on them in the darkness. The stars shone clear and bright in the sky above, and occasionally a little wind swept up the dismal defile. Now and then a loose stone rattled down the sides of shale and volcanic rock, and at such times Dick, and even Yellin' Kid started, and felt for their guns. But all the alarms were false ones. That is, the watchers decided they were, for no sight was had of anyone until Dick, after a stroll about the fire, suddenly started back and whispered to Yellin' Kid: "Isn't that a head looking up over that rock?" The Kid glanced to where Dick directed his gaze, and, in an instant, the cowboy had his weapon out and leveled. His finger was even pressing the trigger when he laughed silently and thrust the .45 back in its leather case. "Why didn't you shoot?" asked Dick. "It was an owl," answered Kid. "It was his ears you seen stickin' up! Listen!" And, a moment later, there was the mournful hooting of the nocturnal bird, which had flown away, but on such downy-feathered wings that it made no sound. "An owl!" murmured Dick. Then he was glad he had not shot first, as he had intended. He would only have awakened the others and been laughed at for his pains. Sometimes, he reflected, it was better to hold your fire, even in the west, that region of quick action. Soon there was a little grayish, pinkish light to be observed over the edge of the eastern hill. It grew slowly, and daylight came, though it was some time before the sun itself was seen, so deep were the searchers down in the defile. After breakfast they set out again, looking carefully for signs of the rustlers, but they saw none, and at last they decided that, in some mysterious manner, their quarry had given them the slip. "Though I don't see how they did it," declared Slim, somewhat vexed that he and his men were not better able to pick up the trail.
