What truth there might be in this supposition, which held a firm hold of the Mexican's mind, we are unable to say at present; but the slightest actions of his capataz were watched by him, and he felt certain that he should, sooner or later, attain a confirmation of his doubts; hence, while feigning the greatest satisfaction with him, he constantly kept on his guard, ready to deal a blow, which would be the sharper because it had been so long prepared.

A little before eleven A.M. the caravan reached the terrace, and it was with a feeling of joy, which they did not attempt to conceal, that the peons recognized the strength of the position selected by their master for the encampment.

"We shall stop here for the present," the Mexican said. "Unload the mules, and light the fires. Immediately after breakfast we will begin entrenching ourselves in such a way as to foil all the assaults of marauders."

The peons obeyed with the speed of men who have made a long journey and are beginning to feel hungry; the fires were lighted in an instant, and a few moments later the peons vigorously attacked their maize tortillas, their tocino, and their cecina—those indispensable elements of every Mexican meal. When the hunger of his men was appeased, and they had smoked their cigarettes, the chief rose.

"Now," he said, "to work."


[CHAPTER VI.]

THE SURPRISE.

The position which the leader of the caravan fancied he had been the first to discover, and where he had made up his mind to halt, was admirably selected to establish an intrenched camp—strong enough to resist for months the attacks of the Indians and the pirates of the prairies. The immense voladero hovering at a prodigious height above the precipices, and guarded on the right and left by enormous masses of rock, offered such conditions of security that the peons regained all their merry carelessness, and only regarded the mysterious flight of the guide as an accident of no real importance, and which would have no other consequences for them but to make their journey somewhat longer than the time originally arranged.

It was, hence, with well promising ardour that they rose on receiving their chiefs command, and prepared under his directions to dig the trench which was intended to protect them from a surprise. This trench was to be bordered by a line of tall stakes, running across the open space between the rocks, which gave the sole access to the terrace.
