"They all went spinning off in the direction of the desert there; and the one I hit must have been ahead of the pack, because I could hear him tooting up at a great rate. Sho! there must have been all of a dozen in the lot! Bet you they don't come around here in a hurry again after that lesson!"

But Andy was mistaken. In less than half an hour the howls started in once more, at first from some distance, but gradually drawing closer, until apparently the coyote concert band was again at the old stand, appealing to Andy to try it once more, and provide them with some further pickings.

Andy, however, refused to be tempted, for Rob, who was also awake, told him he would have to sit up the balance of the night, since the animals were bound to return time and again; nor would he be able to induce them to stop their wailing, since, driven from the vicinity of the camp, they would stand afar off and start a new chant.

All of the boys were glad when the first peep of dawn drove the coyotes to their dens among the rocks in the hills, or some barranca near by.

Just as Rob had said, they would undoubtedly become more or less accustomed to such nightly serenades in time, and pay little heed to the howling. To one used to sleeping in the open, where wolves and coyotes abound, the chorus comes to be a species of protection; and if it suddenly ceased in the middle of the night he would immediately rouse himself to investigate what had driven the pack away, for it must either be a human enemy, or a jaguar.

The boys expected, after partaking of hot coffee and a light breakfast, to resume their gallop toward the south. Andy busied himself in laying the fire, which they had allowed the guide to do on the previous evening, although any one of the boys knew as much about arranging this as Lopez. He had had actual experience all his adventurous life; but, then, they had practiced the art of building cooking fires as one of the duties with which a scout should be familiar, and they knew just how to get the best results.

Besides, the boys had learned something from the way Lopez selected their camp site. They could guess why it was screened by thickets on nearly all sides; and also why it lay in a slight depression, so that the glow of the little blaze might not draw inquisitive strangers, as an exposed light would.

They had learned long ago to keep their eyes open so as to see everything that went on around them. Rob in particular was always on the alert, and if he thought any of the others failed to grasp what a certain thing meant, it was his habit to call their attention to the circumstances. For that is what a patrol leader is expected to do when he has been elevated to his important position.

Andy had just managed to get the cooking fire ready, and was asking Tubby to bring him the frying-pan, because they expected to have a rasher of bacon for breakfast, to go with the hardtack and coffee. At that moment the horse of the guide, staked near by, began to snort and prance, as well as give other indications of excitement. Lopez had been in the act of rolling up his blanket into a small bundle that could easily be carried behind his saddle. He seemed to know instinctively what these riotous actions on the part of his mount stood for; because, with an exclamation of alarm, he jumped for his gun that rested against a tree trunk.

Rob did the same, ditto Merritt; while Andy continued to kneel there in front of his little fire as though frozen stiff. As for Tubby, he dropped the frying-pan in a panic and snatched up the camp hatchet.
