“Well, Thompson is done for, that's dead sure, and we'll have to give him a dacent burial. Whisht, there! did ye not hear somethin'?” Footsteps were heard very distinctly upon the leaves, and the two shrank back in the shadow of the wood and awaited their approach, for they were evidently coming that way. Something in the manner of walking betrayed their identity, and Mickey spoke. The prompt answer showed that they were the two men whose duty it was to relieve Thompson and the Irishman. They came forward at once, and when they learned the truth, were, as a matter of course, terribly shocked. They reported that the sentinels nearer the settlement had detected moving figures during the night skulking about the wood and valley, and the sound of horses' hoofs left no doubt that they were Indians who had gone. The death of Thompson, of course, was a terrible shock to the new arrivals, but it was one of the incidents of border life, and was accepted as such. The two took their stations unflinchingly, and Mickey and Fred returned to the settlement, the body of the dead sentry being allowed to lie where it was, under guard, until morning. On the morrow the body was given decent burial, and the building of the houses was pressed with all possible activity, and scouts or sentinels were stationed on all the prominent lookouts. Barnwell was confident that if no interruption came about within the next two or three days, he could put the defenses in such shape that they could resist the attack of any body of Indians; but an assault on that day or the next would be a most serious affair, the issue of which was extremely doubtful; hence the necessity of pressing everything forward with the utmost dispatch. Fred rendered what assistance he could, but that did not amount to much, and, as he possessed the best eyesight, he took upon himself the duty of sentinel, taking his position near the river, where he remained for something over an hour. Nothing of an alarming character was seen, and, thinking his standpoint was too depressed to give him the range of observation, he concluded to climb one of the trees. This was quickly done, and when he found himself in one of the topmost branches he was gratified with the result. On his right hand, he could trace the winding course of the Rio Pecos for several miles, the banks here and there fringed with wood and stunted undergrowth. His attitude was such that he could see over the tops of the trees in his rear, and observe his friends busily at work as so many beavers, while off on the left, stretched on the prairies, with the faint bluish outlines of mountains in the distance. All at once the eye of the boy was arrested by the figure of a horseman in the west. He was coming with the speed of a whirlwind, and heading straight toward the settlement.
