"Yes; and I think I know where that cave is?" answered Harry.
"Where?" asked Tom and George in a breath.
"Right at the camp where we found you."
"Oh, you mean that cave we found at the hillside after we started for the river?"
"Don't you recall that John took me around to the mouth of the cave, and when we said that we might use that to hide in, he shook his head, and moved away?"
"I thought the Professor acted queerly about it, too, because he urged us away from the place."
All remembered the circumstance, and they also recalled that the Professor gave a vague reply when they asked him the reason why.
George cast a scrutinizing glance at Harry, who waited for him to speak. "Harry, do you think he found any treasure in that cave?"
Ralph and Tom now opened their eyes in wonder. Was that what he meant when he said there was something wonderful there? Harry looked at the boys for a moment, in the intensity of the situation, and said: "And we have also found a cave." But the eyes of George caught Harry, who suddenly stopped, because he recalled their agreement not to divulge it to the boys until the matter was mentioned to him.
"Where is it?" exclaimed Tom, eagerly.
