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.
But with Wharton the case was different. Blazing Arrow's signal succeeded his, and, therefore, was but a clever imitation.
"It may be that he got it from Larry," reflected our young friend, "but the chances are against it. Where can the fellow be?"
It was an exasperating reflection that for hours the work had been of a blind nature, as may be said. The youths had been separated, there had been a fierce race, fighting, and running back and forth, and all manner of incidents, and yet matters stood as at the beginning.
While this was a cause for gratification in one respect, inasmuch as the two were still safe from the most dreaded tribe of Indians in the West, the disheartening fact was that the boys were just where they were when the danger broke upon them. They had not advanced a rod along the trail to the block-house, where Wharton's parents would probably arrive that evening. The prospect was poor for the boys appearing until long after the hour they were expected.
