"I'd like to go on a motorboat trip myself," said Biff Hooper slowly. "As a matter of fact, I know of a place to go, but I don't know whether we can reach it in a boat."
"Where's that?"
"I was talking to an old sailor the other day in one of the villages down the shore and he was telling me a story about some caves that are said to be down on the main shore. We were talking about buried treasure, and that's how he brought the matter up. He said that there were old rumors of treasure in these caves."
"Treasure!" exclaimed Chet, brightening up. "That's our meat!"
"Of course, I'm not saying there is treasure in these caves. But the old chap said he had heard the story and he thought there might be something in it."
"In the caves, you mean," said the irrepressible Chet.
"Sure! These caves are out on the coast, south from the mouth of Barmet Bay."
"It wouldn't take us very long to go down and look the place over," Frank remarked.
"They're not easy to reach. I'm not sure that we can get to them by motorboat. But I believe there's a road that runs down the coast in that neighborhood and we might be able to get there by land."
"We have the motorbikes," said Joe promptly.
