Just as he had straightened out his limbs, preparatory to emerging from his uncomfortable hiding-place, Ayres paused. Another alarm rung out upon the air, from beyond the wagon-train.

Then came a single shrill war-whoop, that he had so often listened to on that eventful night, followed by wild shouts from the Indians, telling of some important discovery. And then, from almost directly above his head, there sounded a guttural exclamation, closely followed by the tramp of human feet.

Ayres shuddered convulsively as he realized the extent of the peril he had so nearly brought upon himself, by his rash action. He knew now that the red-skins had indeed been lying in wait for him, and only for this strange diversion, would inevitably have made the desired discovery.

Though sadly puzzled to account for the outcry—for Ayres well knew that the latter cries were those of exultation—the young man dared not dally longer, but slipping forth from his hiding-place, he swam rapidly down-stream for a few yards, until near the end of the timber-belt furthest from the corral.

Then he cautiously scaled the bank, and entered the dense undergrowth. Pausing, he hearkened intently.

All was still in his immediate vicinity, although from near the wagon-train he could hear an occasional rifle-shot, telling that his friends were still upon the alert. And then he glided stealthily forward until at the edge of the prairie.

Cautiously peering forth upon the vast, level expanse thus spread before him, Buenos saw with delight that as far as his eye could reach, there was not a single living form to be seen. The road appeared open before him, and he was about to enter upon it, when a sudden recollection caused him to pause.

The revolver was still strapped upon his head, according to the advice given him by Tom Maxwell, but it was far from being in a condition fit for use. The sudden dive, on seeing the savage beside the log, added to several immersions since, had pretty thoroughly saturated it.

Not knowing at what moment he might be called upon to make use of this, in order to preserve his life, Ayres’ first move was to draw the bullets, and wiping the chambers dry, he carefully reloaded them. Then fitting on the water-proof caps, he replaced it in his belt, and once more stepped forth upon the prairie.

Had he not already lost so much time, Buenos would probably have exercised more precaution than he was now using. But, racked with anxiety and the dread of being too late to aid his comrades in peril, rendered him half wild.
