"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." He had reached the mouth of the cavern again, where his sister was anxiously waiting him. "Did you find anything of him?" "No," he answered, with a shake of the head. "I believe you are right; the man has gone off somewhere after his promise to keep watch over us while we slept; that's enough for me. Is Ned awake?" "Not that I am aware of." "He must be aroused at once, for it will not do to stay here after what has taken place." Jo passed inside and awakened his friend, without pausing to be very gentle as to the means. It took but a minute to make plain the trouble. He became as alert and suspicious as they on the instant. "There!" he exclaimed; "I had a suspicion when he came under the tree that I had seen him somewhere." "So had I, but I couldn't recall where and when it was." "Don't you remember when the battle was going on the other day, we saw one man among the Tories who was tomahawking the whites as savagely as any of them?" "Yes, I remember him well, but he didn't look like this fellow!" "Not a great deal, that's true, but I believe it was he for all that." Jo was silent for a moment, as if in deep thought. "There was something about him that reminds me of this fellow, though one had whiskers and the other had not, and it is hard to tell just how they resemble each other." The youths were more anxious to take themselves and Rosa away from the cavern than they were to discuss the question, upon which they agreed quite well. Hastily picking up their rifles, they passed outside. When they found themselves within the shelter of the wood again, and beyond the vision of any one who might approach the retreat, the relief was inexpressible. "We agree that the counsel of Rosa was wise," said Ned Clinton, as they came to a halt, "but you see how it may be possible she was mistaken. Now it won't do to go wandering too far from the place, for when the Mohawk comes back and finds us gone he may not hunt for us." "Why not, then, go back over the same route that we followed in coming here?" asked Jo. "That is what I would like to do, if it wasn't for the danger; it seems to me that that is the path which Worrell will take when he starts for the cavern again with his Indians, and we don't want to meet him face to face, for we can do that by waiting in the cavern." "I have it!" exclaimed Ned. "I will take the back trail alone, on the lookout for the Mohawk and for the white man, too. What do you say?" "And shall Rosa and I wait here till you come back?"
