If he could hold the rustlers for ten minutes more they would be caught like rats in a trap. Once or twice he glanced behind him as a precaution against some one of the enemy climbing Point o' Rocks from the defile, but he gave this little consideration. He had not seen Brad when he disappeared into the mesquite, and he supposed all of the rustlers were still in the Pass five hundred feet below him. What he had expected was that they would force their way up the defile for a quarter of a mile and strike the easy trail that ran from the rear to the top of the Point. He wondered that this had not occurred to Healy. In point of fact it had, but the outlaw leader knew that as they picked their way among the broken boulders of the gulch bottom the enemy would have them in the open for more than a hundred yards of slow going. He had chosen the alternative of sending Brad quietly up the rough face of the cliff. The other plan would do as a last resource if this failed. Healy believed that his enemy had been delivered into his hands. After Keller had been killed they would toss his body down into the Pass, and while his companions continued the drive to Mexico, Healy would return to get help for Duke and spread the story he wanted to get out. The main features of that tale would be that he and Duke had cut their trail by accident, suspected rustling, and followed as far as the Mimbres Pass, where Keller had shot Duke and been in turn shot by Healy. It was a neat plan, and one that would have been fairly sure of success but for one unforeseen contingency--the approach of Yeager's posse a half hour too soon. Healy heard them coming, knew he was trapped, and attempted to force an escape through the narrows in front of Point o' Rocks. The milling cattle had jammed the gateway. Keller, shooting down one or two of them, blocked the exit still more. Healy and his confederates could not get through, and turned to try the defile just as the first of the posse came flying down the Pass. Young Sanderson was in the van, a hundred yards in front of Yeager, dashing over the uneven ground in a reckless haste that Jim's slower horse could not match. Loose shale was flying from his pony's hoofs as it pounded forward. The outlaws just beat him to the mouth of the intersecting gulch. Dragging his broncho to a slithering halt, he fired twice at the retreating men. He had taken no time to aim, and his bullets went wild. Brill laughed in mockery, covered him deliberately with his rifle, and just as deliberately raised the barrel and fired into the air. The distance was scarce a hundred yards. Phil could not doubt that his former friend had purposely spared his life. The boy's rifle dropped from his shoulder. "Brill wouldn't shoot at me! I couldn't kill him!" he shouted to Weaver, as the latter rode up. Buck nodded. "Let me have him!" And he plunged into the gorge after the men that had disappeared.
