The lad moved away several steps, and Mickey, who made sure that his form was not revealed by the light of his own camp-fire, circled around to the other side of the opening, which he was watching with the keenest interest. His purpose was to catch a glimpse of the wretch who had fired the shot. But that seemed about impossible. He could detect something moving now and then, and once or twice there was a twinkle of something red, like the eagle feather in the hair of the warrior, but he could make out nothing definitely. “He's there; and all I want to do is to be certain of hitting him,” he muttered, as he held the cocked rifle to his shoulder. “I'm afeard that if I miss he'll take such good care of himself that I won't get another chance---” “There, Mickey, there's something,” broke in Fred, who was scrutinizing the opening as closely as he could. “Fire, quick! or you won't get the chance!” The words were scarcely uttered, when the Irishman, who had already taken aim, pulled the trigger, instantly lowering his piece to watch the result. Both he and Fred fancied they heard an exclamation, but they could not be certain. There was no perceptible commotion about the skylight, but the flickering, erratic movement which had puzzled them ceased on the instant. Whether the shot had accomplished anything or not could only be conjectured, but Mickey was of the opinion that the exchange was equally without result in both cases. CHAPTER XXXII. FOOTSTEPS IN THE DARKNESS The direct result of this exchange of shots was to make the two parties more cautious. Mickey and Fred kept further away from the camp-fire, which they suffered to die out gradually. There was really no need fot it, and, since its presence meant danger, it was only prudent to dispense with it altogether. For fully a half hour not the slightest movement or disturbance at the opening betrayed the presence of any one there, although there could be no doubt that their enemies were within call. “I can't see what they can gain by loafing around them parts, as the lassies used to obsarve in the ould country when any of the laddies tried to cut me out wid 'em. They need n't watch for us to come out that way, for there ain't much danger of our trying to steal out of that hole---” “Holloa! Look there!” exclaimed Fred, in considerable excitement; “some of them are coming down to catch us.” Mickey had already noticed that something unusual was up, and, just as the lad spoke, the figure of what seemed to be a man blocked up the opening, and then began slowly descending, as if supported by a rope, with which his friends were lowering him into the lower room. His form was swathed with a blanket, and there was a certain majesty in the slowly sinking figure, which would have been very impressive but for the fact that it was hardly started when the thin cord by which it was suspended began to twist and untwist, causing the form to revolve forward and backward in a way that was fatal to dignity.
