He brought out the little flashlight and tried it. Fortunately, it was still in working order. As the rays fell around the lads, they stared at each other, blankly.

“What do you make of this, Dave?”

“Looks as if it was cut out of the solid rock, Roger.”

“It certainly is some cave. Wonder where it leads to?”

“We might follow the opening and find out.”

“Excuse me, I’d rather climb out the way we came in.”

“It certainly doesn’t look very inviting.”

The two boys found themselves in an irregular opening of the rocks, fifty feet wide and perhaps twice that in length. On one side was the smooth slope down which they had come; on the other a dark hole that looked as if it might lead to some bottomless pit. A jagged rock in the center of the underground chamber had been the means of stopping them from dropping to the unknown depths below them.

“We were lucky to hit this rock,” said Dave, with something like a shiver. “If we hadn’t——” He did not finish.

“Let us get out. It gives me the creeps to stay here,” returned his chum.
