He had not seen the youth after he watched him disappear across the clearing where the back trail entered the woods. He never suspected that he was not on his front on the return, and failed to see his last leap across the torrent. Confident, however, that he was not far off, he began a search for him, with the hope of getting matters in better shape before rejoining his comrades with an account of his experience. It happened, therefore, that when young Edwards made his dove-call to Larry Murphy, Blazing Arrow was so near that he heard it. He knew that it came from none of his people, and consequently must be from one of the whites. With extraordinary cleverness he replied by several notes, whose resemblance to those causing them was so wonderfully close as to be perfect. Fearful, however, that he might not have hit the exact note, he repeated the call. And in doing so he made the fatal blunder. One of the unchangeable laws governing Wharton Edwards and Larry Murphy at such times was that under no circumstances was either to repeat a signal without a minute or two interval. It was the violation of this rule that apprised the youth of his peril and gave him time to save himself. Suspecting that it was Blazing Arrow who was near, Wharton retreated farther into the wood. In making the movement he used all the caution he could, and believed that no one had overheard him. What followed looked as though he was right in the conclusion, for the Indian, without moving from his tracks, signalled again, making the same mistake as before by repeating it, in his effort to repress his impatience at the delay in the response. "I don't think I'll be in a hurry to open a conversation with you," thought Wharton; "I'm looking for somebody else." He was still in a dangerous situation, however, and continued edging away from the locality where he had come so near falling a victim to the resentment of the warrior, who was among the most cunning of his tribe. Wharton's heart sank when, despite the extreme care he used, he caught his foot in a running vine and narrowly escaped falling. He instantly straightened up and waited for the attack that he was sure was coming; but, as the minutes passed, he concluded the Indian was already so far off that the slight rustling did not reach him. It was probable that the Shawanoe, in trying to outwit the youth, had moved away from him, and the two were now separated by a considerable space. How was it that this Indian was in possession of the signal which the two youths used when in danger? In the case of Wharton, however, there was little of the anxiety of his friend. The latter heard the call before emitting it himself, so that it was impossible that Blazing Arrow should have got it from him; and, since Wharton Edwards was the only other person that possessed it, the misgiving of the Irish lad was warranted.
