Just before Point o' Rocks a defile runs into the Mimbres Pass at right angles. The leaders of the cattle, pushed forward by the pressure from behind, stopped for a moment, and stood bawling at the junction. A rider spurred forward to keep them from attempting the gulch. Suddenly he dragged his pony to its haunches, so quickly did he stop it. For a clear voice had called down a warning as if from the heavens: "You can't go this way! The Pass is closed!" The rider looked up in amazement, and beheld a man standing on the ledge above with a rifle resting easily across his forearm. "By Heaven, it's Keller!" the rustler muttered. He wheeled as on a half dollar, pushed his way back along the edge of the wall past the cattle, and shouted to his chief: "We're trapped, Brill!" None of the outlaws needed that notification. Five pair of eyes had lifted to the ledge upon which Keller stood. The shock of the surprise paralyzed them for an instant. For it occurred to none of the five that this man would be standing there so quietly unless he were backed by a posse sufficient to overpower them. He had not the manner of a man taking a desperate chance. The situation was as dramatic as life and death, but the voice that had come down to them had been as matter-of-fact as if it had asked some one to pass him a cup of coffee at the breakfast table. The temper of the outlaws' metal showed instantly. Dixon dropped his rifle, threw up his hands, and ran bleating to the cover of some large rocks, imploring the imagined posse not to shoot. Others found silently what shelter they could. Healy alone took reckless counsel of his hate. Flinging his rifle to his shoulder, he blazed away at the figure on the ledge--once, twice, three times. When the smoke cleared the ranger was no longer to be seen. He was lying flat on his rock like a lizard, where he had dropped just as his enemy whipped up his weapon to fire. Cold as chilled steel, in spite of the fire of passion that blazed within him, Healy slid to the ground on the far side of his horse and, without exposing himself, slowly worked to the loose boulders bordering the edge of the canon bed. The bawling of the cattle and the faint whimpering of Dixon alone disturbed the silence. Healy and his confederates were waiting for the other side to show its hand. Meanwhile the leader of the outlaws was thinking out the situation. "I believe there's only two of them, Bart," he confided in a low voice to the big fellow lying near. "Keller must have heard us when we talked it over at the shack. I reckon he and Phil hit the trail for here immediate. They hadn't time to go back and rustle help and still get here before us. "We'll make Mr. Keller table his cards. I'm going to try to rush the cattle through. We'll see at once what's doing. If they are too many for us to do that we'll break for the gulch and fight our way out--that is, if we find we're hemmed in behind, too."
