He got into position to act, moving only when the slight sound of Kane's footfalls would cover the barely audible noise of his own movements. Kane's rounding course brought him nearer and then several things happened at once. The owner of the hand leaped from behind the rock and as his head popped out into sight a Colt struck it, and then Johnny started for Kane; but as he reached his feet something hurtled out of the shadows to his right and bore the boss to the ground. Then came the sound of another gun-butt meeting another head and the swiftly moving figure seemed to rebound from the boss and sail toward Johnny, who had started to meet it. He swerved suddenly and muttered one word, just as Hopalong swerved from his own course. They both had turned in the same direction and came together with a force which nearly knocked them out. Holding to each other to keep their feet, they recovered their breath and without a word separated at a run, Hopalong going to Kane and Johnny to Trask. Less dazed by the collision than his friend was, Johnny finished his work first and then helped Hopalong carry Kane to the shelter of the rock. "Good thing you forgot what I said about watchin' them Greasers," grunted Hopalong. "It's them next, if--" his words were cut short by two quick shots, which reverberated throughout the valley, and without another word he followed his running companion, and scorned cover for the first few hundred yards. When they got close to the trail they saw two bulks on it, which the moonlight showed to be prostrate horses. "Where are they, Red?" shouted Johnny. "They're th' only ones free!" "Down near you somewhere," answered the man above, and his words were proved true by a bullet which hummed past Johnny's ear. He dropped to his stomach and began to wriggle toward the flash of the gun, Hopalong already on the way. Cut off from escape up the trail the two Mexicans tried to work toward the hut, from which they could put up a good fight; but their enemies had guessed their purpose and strove to drive them off at a tangent.
