"The question is, now we are down at the bottom of this hole, how are we going to get out?" said Dick to Peterson.

"We'll have to get out some way," was the unsatisfactory response. "See, the water is coming in faster than ever."

What had caused the sudden sinking was a mystery until it was solved by the water in the pool suddenly dropping away into another hole still deeper. Then of a sudden the trio went down again, this time at an angle, to find themselves in a good sized cave, where all was dark and uncertain.
