As Jack had said, if they could gain this portion of it, it ought to afford them an ideal hiding-place.

Rapidly they pressed forward along the rough bottom of the gulch, which was evidently a roaring water-course in times of heavy rain, but which was now as dry as a bone. It was stiflingly hot, too, but none of them noticed that. Other things far more overwhelming in importance, were upon their minds just then.

Evidently, such skilled trackers as the Mexicans, had not been at fault in locating the woods into which the boys had vanished. The yells and cries, which Jack had heard, were rapidly drawing nearer in the woods above them. But, if they could only gain the shelter of the overgrown part of the gulch, they might still be safe.

It was in this extremity that Jack bethought himself of an old trick he had heard the cow-punchers talk of at his father's ranch. They had used it in old frontier days, when the Indians were thick and hostile. The deception was a simple one. It consisted in the hunted person slipping from his horse at a suitable hiding-place and then letting the animal wander on.

The pursuers would naturally be guided by the sound of the horses' hoofs, and would follow them up, leaving the concealed victim of the chase at liberty, either to double back upon his trail, or remain where he was. His intention of putting this trick into execution Jack rapidly confided to his two companions. They rode forward through the thick brush, which they had now gained, gazing eagerly at the walls of the gulch for some cave, or other suitable place of concealment.

Suddenly Walt spied the very place which they were in search of, apparently. It was a small opening in the rocky wall of the gully, which appeared from below to penetrate quite some distance back into the earth. Its mouth was sheltered with brush and creepers, and but for the fact that a bird flew out from it as they passed, and thus attracted their attention, they might have passed it unnoticed.

A brief inspection showed that it was a small cave, about twenty feet in depth, and, as has been said, well screened from below.

"We're not likely to find a better place," announced Jack, after a hasty inspection.

"Turn the horses loose," he cried in a low, but penetrating voice, down to Walt, who had remained below with the stock.

The red-headed ranch boy slipped off the back of his steed and alighted on a rock, so as to make no tracks. He then gave the three horses, that had borne them so bravely, their liberty. At first the animals would not move, but began cropping the green stuff about them.
