Ayres shrunk back against the bank, where the water was still several feet deep. He clutched his knife with desperation, resolved to sell his life dearly, should he be discovered. But then his heart thrilled with a gleam of joy.

In the bank beside him was a small hole or depression, that had evidently been washed out by the action of the water. Instantly one hand was extended to ascertain its size.

It only reached a few inches above the surface, and was over a foot in depth, running back into the bank. Below, it was still larger, and Ayres believed that by its aid he could still escape his foes.

All this occurred in a breath of time, and the water was still agitated by the heavy plunges, when Buenos glided back and into the fortunately discovered refuge. By crouching almost double, he managed to stow his body away in the hole, with his legs doubled beneath his body.

A quick gesture daubed his face with the soft black mud, and then Buenos awaited the result in painful surprise. For not only did his own life depend upon it, but, in all probability, those of his friends in the besieged corral, as well.

His head was drawn back into the hole, so that his nose was barely above water, and his face beyond the surface of the bank. The mud had rendered his features the color of the dirt surrounding, and only by touching him, could the savages have discovered the difference.

Through his half-closed lids, Buenos watched the movements of the savages, now almost directly opposite him. A shower of dirt rolled down from above, telling that those he had noticed on shore were still near at hand.

Then a new and startling sound came to the ears of the young adventurer. He heard the shrill yells—the wild outcry—the rattling of rifles, all telling of another deadly assault upon the wagon-train.

The savages in the water paused as if startled, and then hastily grasping the body of their dead comrade, they swam rapidly ashore with it, landing just below where crouched the young man. Words passed between them and the others, the purport of which Ayres could only guess, owing to his complete ignorance of the dialect.

Then the corpse was handed up the bank, and shortly afterward Buenos heard the quick trampling of feet, as a number of Indians dashed away toward the train. He believed they were all gone, and made a movement as though he would have left his covert, in order to continue his journey, without any more loss of time.
