And what action? They could think of none—none but open action. What! dare a man not claim his own sister? Demand her restoration?

But the thought of refusal—the thought of subterfuge—in fact, the certainty that such would be the result—quite terrified them both.

And yet how else could they act? They would at least give publicity to the atrocious deed; that might serve them. There would be sympathy in their favour—perhaps more. Perhaps the people, slaves as they were, might surround the Presidio, and clamour loudly;—in some way the captive might be rescued. Such were their hurried reflections.

“If not rescued,” said Carlos, grinding his teeth together, “she shall be revenged. Though the garrota press my throat, he shall not live if she be dishonoured. I swear it!”

“I echo the oath!” cried Don Juan, grasping the hilt of his machete.

“Masters! dear masters!” said Antonio, “you both know I am not a coward. I shall aid you with my arm or my life; but it is a terrible business. Let us have caution, or we fail. Let us be prudent!”

“True, we must be prudent. I have already promised that to my mother; but how, comrades?—how! In what does prudence consist?—to wait and watch, while she—oh!”

All three were silent for a while. None of them could think of a feasible plan to be pursued.

The situation was, indeed, a most difficult one. There was the Presidio, and within its walls—perhaps in some dark chamber—the cibolero well knew his sister was a captive; but under such peculiar circumstances that her release would be a most difficult enterprise.

In the first place, the villain who held her would assuredly deny that she was there. To have released her would be an acknowledgment of his guilt. What proof of it could Carlos give? The soldiers of the garrison, no doubt, were ignorant of the whole transaction—with the exception of the two or three miscreants who had acted as aides. Were the cibolero to assert such a thing in the town he would be laughed at—no doubt arrested and punished. Even could he offer proofs, what authority was there to help him to justice? The military was the law of the place, and the little show of civic authority that existed would be more disposed to take sides against him than in his favour. He could expect no justice from any quarter. All the proof of his accusation would rest only on such facts as would neither be understood nor regarded by those to whom he might appeal. The return trail would be easily accounted for by Vizcarra—if he should deign to take so much trouble—and the accusation of Carlos would be scouted as the fancy of a madman. No one would give credence to it. The very atrociousness of the deed rendered it incredible!
