"I guess there's not much danger of an attack now," said Bud bitterly. "I wish there was. I'd give a new saddle for a crack at one of them greasers."

Soon afterward, with Bud riding double behind Ellis, and Mr. Merrill's saddle bearing the wounded Mexican, the sorrowful party began the journey back down the cañon. With every sense and muscle aching for action, they were compelled to await the decision of time. The clew to the attack, and the whereabouts of Black Ramon and his gang, lay in the hands of one man, and that man was unable to speak. No wonder that as they rode, the thought in Mr. Merrill's mind was to get medical attendance for their wounded foe as soon as possible, and in the meantime give him the best of care.

As Bud had said, he might be valuable for future reference.


As their ponies' hoofs hammered over the rough bridge the Border Boys' minds had burned with but one thought. They must capture the treacherous guide who, it appeared only too evidently, had led them into a trap. As their mounts flew by a dense brush mass on the rocks at the farther side of the precipitous gorge, they had glimpsed for a second a crouching figure. But such was their wish to catch up with the treacherous Jose that they paid the figure no attention. Yet had they done so, they might have prevented the destruction of the bridge. The crouching man was one of Black Ramon's followers, and in the brush was concealed the battery from which led the wires which were to blow up the bridge.

"I'd give a new lariat right now to have my fingers on that sneaking coyote's throat," gritted out Walt Phelps, as the ponies loped swiftly along.

A little ahead of the Border Boys, rode the large, angular figure of Coyote Pete, bestriding his big, raw-boned bay with the careless ease of the old plainsman. The ends of his scarlet handkerchief whipped out behind his neck, and he gnawed his long, straw-colored mustache nervously as he kept his keen, blue eyes, with a maze of little desert furrows round them, centred on the crouching figure of the Mexican ahead. The professor having by this time checked his horse and recovered his equilibrium, gazed about as eagerly as the rest.

The treacherous Jose, however, seemed to have a good mount, for even Coyote Pete's powerful bay, and the active little ponies bestrode by the boys, failed to draw up on him even after a mile of fast riding.

"That horse-stealing son of a rattlesnake has a good bit of horse flesh there," grunted the cowboy, turning in his saddle without slackening speed.
