“But Jo had an awful scare,” broke in Tom.
“You mean you did,” protested Jo.
“How was that?” asked the professor.
“Why, we found a cave with the entrance way up in the air. We thought at once that it was the one we were looking for, but it did not turn out to be,” explained Tom. “And then we found a lot of skeletons in there, and they got after us.”
“The skeletons did?”
“Well, something did,” replied Tom with a grin. “Then Jo and I beat a hasty retreat.”
“Each got hold of the other in the dark,” explained Jim, laughing, “but I guess they had a jolly time of it till they broke away and ran. It sure was funny.”
“Are you certain there wasn’t anything unnatural in there?”
“We couldn’t find anything alive except some bats, when we went back,” replied Tom, “although we hunted all over.”
