As seen outlined against the gray sky beyond, the man appeared to be turned half way around. Instead of looking toward the quarter where the kite flew, his attention seemed to be wholly taken up in the opposite direction. Amos was puzzled to account for this at first, but he quickly grasped the meaning. Of course, the spy was looking for some sign that would tell him his message had been seen and understood by those for whom it was intended. Jack’s hand fell on the arm of his chum. Although no arrangement had been made between them, Amos guessed that the time was at hand for the _coup_ his companion had arranged. Then Jack gave tongue, and his experience on the cattle ranch in company with a lively set of cow-punchers had made him a first-class hand at letting out a fierce whoop. Amos joined in with what vim he could muster, so that, taken in all, they managed to create a pretty respectable disturbance around that region. It turned out just as Jack had surmised would be the case. The man who was signalling over the British lines to his German confederates immediately dropped the end of the cord connected with the kite that bore the twin red lights. Amos, still shouting at the top of his voice, saw him duck down as though meaning to dodge any bullets that might be sent in his direction. After that, the figure of the spy was seen no more between them and the gray heavens. Judging from the medley of sounds that came from the other side of the mound it might be guessed that the man, either intentionally or through sheer accident, was rolling headlong down the slope. Jack stopped yelling, and broke out into a laugh, in which his cousin naturally joined. “Look at the kite falling!” the Western boy called out, and Amos turned just in time to see the twin red lights before they vanished behind some trees or other obstruction to his view, dropping lower all the time. “We’ve done what we aimed to accomplish, Jack,” he went on to say, when he could catch his voice. “After all, it was as easy as falling off a log.” “But I’m afraid he had his message up in the sky, whatever it stood for, long enough to do its work.” As Jack said this he clutched hold of the other and whirled him around again so that his face was toward the northwest. “That looks like a bursting rocket, as sure as you live!” exclaimed Amos, as he discovered a shower of colored stars far away, that seemed to be floating in space. “It is just that,” admitted his chum. “If I was over home I’d guess the Glorious Fourth had come around, Jack, though it’s generally considerably hotter than we’ve got it here. Do you think that rocket’s got anything to do with this red-fire kite business?” “A whole lot, I should say, Amos.” “You mean it was sent up in answer to his signal?” “To tell him they saw and understood,” replied Jack. “Then our work was for nothing,” grumbled Amos.
