Lieutenant Decker was as indisposed as any of his companions to remain idle until the rising of the sun. Accordingly the three best scouts, including Mendez, were sent out to locate the raiders, if possible, with a view of attacking them at the earliest moment. In their absence, the troopers dismounted and lolled about in the sand, some snatching a little sleep, others smoking and talking in low tones, while the sentinels, as a matter of course, were placed at the proper points to guard against surprise.

Martin, one of the white scouts, went up the stream, Potter, another, took the opposite course, while Mendez rode his pony to the other side. The other two were also mounted, for it will be understood that their duty differed from that of the Apache scout, when he first went out. It was then an object with him to steal as close as he could to the raiders, with a view of learning their purposes, and it has been shown how well he did his duty.

In the present instance, however, it was only necessary to find out where the main body of hostiles were. The instant that became known, the one making the discovery would hasten back with the information. If well mounted, he could do this much more successfully than if on foot.

It was not to be supposed that the hostiles would be on the alert against such an enterprise, and the scouts undertaking it were hopeful of making their discovery and getting back within an hour from the time of their going forth.

The most dangerous proceeding, as it seemed, was that of Mendez in crossing the stream, for the presumption was that the enemies were on the other side. If he should be seen, as was quite likely, when he located the raiders he would have to make a desperate ride for life. It would not do to dash into the stream, for his progress would be so checked that he would become the best of targets for his enemies.

Recalling where he had last seen Geronimo and his bucks, Mendez rode in that direction. He knew he would not find them there, for his last glimpse showed them leaving the spot, but he made his way thither without detecting the first sign of them.

In the strong moonlight, the scout could readily see the footprints of the horses, without leaning over from the back of his own steed. The trail led up the stream, keeping quite near it, and then, to the surprise of the scout, it circled to the left and away from the water.

He could not fathom the meaning of this, nor indeed did he try to do so, for the special necessity did not exist, but he kept to it, his horse advancing slowly, while the rider peered into the gloom on every hand. The situation became more critical every moment.

The trail showed that the raiders were keeping well together and their animals were walking. Here and there diverging hoofprints indicated that one or more of the horsemen had drawn off from the main body, or else two separate trails crossed each other.

The circle swept inward upon the plain, and by and by turned backward, that is to the west. To the astonishment of Mendez, it began approaching the stream, as if the hostiles meant to recross it. If this were the fact, Potter, who had gone down the bank of the creek would probably be the first to discover the Apaches.
