"To tell the Indians we are here!"
Jo sprang to his feet.
"What are you talking about, Rosa? What do you mean?"
"Just as I say; he has gone to bring the Indians, and will soon be back, too."
"How do you know that?"
"Don't ask me, but I know what I say."
This was alarming news, and though Jo suspected his sister based all upon her dislike of the man, without positive knowledge of the facts, yet he was impressed with the belief that she had good cause for her words.
"He may be on the outside, keeping watch," said the youth, after they had talked over the matter. "Wait till I take a look. If he can't be found, we'll awake Ned."
Jo crept out of the cavern dreading a hostile shot as he did so, and made as thorough an examination of the surroundings as was possible. He saw nothing of the man whom they missed, that individual at that moment being a quarter of a mile or more away, holding his vehement argument with Captain Bagley about the advance with the six Iroquois upon the sleeping fugitives. His invisibility confirmed the young man in his misgivings as to the treachery of the man.
"I have no doubt Rosa is right," he muttered, as he walked thoughtfully back toward the cavern. "She was always quick to detect anything like that, and it is strange that neither Ned nor I had any such thought. The only thing that troubled us was whether we could convince Lena-Wingo we did right in leaving the place where he left us. The thought never entered our heads that there was anything of this kind in the wind."
