"Clear through to that funnel-shaped place where our pack horse fell down."
"Walter! That's an idea!" admitted Nan.
"Guess it is," he returned, smiling. "Let's get them to search the cavern first. We've got lanterns and a big electric torch. There is one thing I want to assure myself about, too," he added.
"The treasure, of course."
"Something more. I want to know what made that noise that frightened you girls so."
"Oh, Walter! I had forgotten about that. Why remind me?" cried Nan.
"Well, don't remind the others, then," laughed Walter.

Tom and Hess Kane entered the cave with the party of young people.
The place was utterly dark and utterly silent. But they soon lit the lanterns, and Walter went in advance with the electric torch.
