"Now for the others!" yelled Walt; but even as he uttered the cry, there came another shout from beyond the bushes in which the battle was being waged: "Ramon! Ramon the Black!" CHAPTER XV. A RACE FOR LIFE. The electric thrill that passed through the lads at the words, and temporarily rendered them powerless to move, would have speedily made them an easy prey for the aggrieved Mexican officers, but that the latter were equally excited by the announcement. The mention of Ramon's name, in fact, seemed to cause a galvanic wave of activity throughout the bivouac. Men could be heard running hither and thither, and above all sounded the heavy trample of the new arrivals' horses. In less than two minutes the last of the wounded Mexicans had picked himself up from the ground, and, clapping a hand over a rapidly swelling "goose egg," was hurrying from the scene of the sudden battle. The last to get up was the pudgy little officer whom Jack had overthrown. This fellow painfully scrambled to his feet, and, breathing the most terrible threats in his native tongue, limped off. The boys stood alone on the card-strewn, coin-littered battle-ground. Dismay was pictured on their countenances. The crucial moment had come, and they were fairly caught in a trap from which there seemed to be no possible means of extricating themselves. "Come on, boys," cried Bob Harding, who had quite recovered his equanimity, "here's your friend Ramon, now." He hastened off, not even looking to see if the supposed adventurers were following him. Suddenly, while the three lads stood regarding one another, there came a high-pitched voice ringing clearly above the confusion and shouts: "You consarned yaller coyote, you take yer leathery lunch-hooks off me, or I'll fill yer so full uv holes your ma can use you for a collander!" "Coyote Pete!" exclaimed Jack. "Oh, boys, he's all right!" "Oh, Jack! What are we going to do?" gasped Ralph, pale under his coat of tan, and looking about him nervously. "We must act quickly, whatever it is," exclaimed Jack. "Thank goodness, Coyote Pete is safe. The professor must be all right, too, then. Look, there are the Mexican's horses off yonder. Let's make a dash for them, and try to sneak out while they are still looking for us." "Do you think we can do it?" Ralph's voice was full of hesitancy. "If we don't, we'll all be lined up with a firing squad in front of us within the next ten minutes!" exclaimed Jack. "Hark!" They could hear shouts and angry cries, above which Ramon's voice sounded, as if he were narrating something. "He's telling them about us," cried Jack. "Come on; there's not a fraction of a second to lose."
