The action of the Indians gave Wharton a suspicion of the truth. They had crossed the torrent with the intention of hiding somewhere along the path leading to the block-house, so as to cut off the flight of one or both of the boys in that direction. This, seemingly, was an easy thing to do, provided the fugitives were unsuspicious of what was going on. Young Edwards saw no way of breaking through the maze of perplexity that had closed around him. He had done his utmost without learning where his friend was. More than that, although he was hopeful, he could feel no certainty that he was really alive. The occasion justified another appeal to the peculiar dove signal, and he now made it. CHAPTER XV. A HAIL AND AN ANSWER. Meanwhile Larry Murphy was not idle. He had never received a more terrifying shock than that caused by the discovery that the signal which he was confident was made by Wharton Edwards came from the lips of Blazing Arrow. On the first thought there was but one explanation of this: his friend had called to him and had been overheard by the Shawanoe, who instantly caught it up, well knowing its significance, and had deceived Wharton by his clever imitation. This supposition, as the reader knows, was correct; but when Larry went further, and decided that his comrade had fallen a victim to the treacherous red man, the reader also knows he made a mistake. Firm in the terrible belief for the time, he was so overcome that he sat down on a bowlder, too faint and weak to stand, until several minutes had passed. "This is a bad go, is this same," he mused with a deep sigh. "If the Indians had to take one, why didn't they take mesilf? They're likely to do the same--it's little I care if they do." So extreme was his dejection, that had he known that a half dozen Shawanoes were stealing upon him at that moment he would not have stirred from his position or attempted to defend himself. This intense depression, however, could not last. All strong, rugged natures are quick to rebound from such pressure and soon reassert themselves. By and by he felt a grain of hope. The rifle lying across his knees was clasped more firmly; he raised his head and listened; had he discovered the approach of a foe he would now have defended himself. "I wish that Blazing Arrow would walk out in front of me and dare me to tackle him," he muttered, gnashing his teeth. "I wonder where he is?" He rose to his feet and peeped around in the gloom. A while before he had shunned the chief, and counted himself fortunate because he was able to escape a meeting. Now he would have felt doubly fortunate could he have gained a chance to attack him. When the Shawanoe was wanted he was somewhere else. "I wonder," continued Larry, as hope grew stronger within him, "whether Whart wasn't sharp enough to play the trick on Blazing Arrow that he did on mesilf? He must have heard the call, to larn how to make the same; but Whart may have give him the slip."
