While he had been engaged with his officer, the others had had their hands full.

Like a snarling pack of wolves, the Mexicans had withdrawn and suddenly made a swoop on them all at once. Defending themselves as best they could, Walt, Ralph and Bob Harding were, nevertheless, driven back against the bushes. So far as Walt and Ralph were concerned, it was a real fight, but with Bob Harding it was different. His face was a sickly yellow, and in his eyes was a light that Jack had seen before—the expression of a coward at bay.

"Keep 'em off, fellows—I'm coming!" yelled Jack, as he charged into the thick of the fray. "The reinforcement was totally unexpected by the Mexicans, and they fell back for an instant—but 'for an instant only.

"Bah, it is only another of those boys!" cried the one who seemed to be their leader, a fat, pudgy little fellow, with a thick, drooping, black moustache.

"Death to the Gringoes!" yelled his followers, their deep-lying hatred of Americans now stripped of its veneer of politeness, and lying exposed in all its ugliness.

The fat, pudgy little officer made a rush at Jack, who, instead of meeting it, ducked and caught the other by his wrist. The fellow's sword went flying, and, at the same instant, Jack made a quick turn. As he did so, the pudgy man's rotund little body was seen to rise from the ground and describe an aerial semi-circle. He came crashing to the ground with a thud, his thick neck almost driven into his shoulders by the force of the concussion.

"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!"
