"Say, wouldn't this make a good place to camp out in?" asked Roger, of the old miner.
"Not much!" was the quick answer.
"Why not? It would be cool in the daytime and warm at night, with a little campfire."
"Maybe, lad. But wot if some o' these rocks should shift? They'd squash ye as flat as a flap jack!"
"I didn't think of that."
"I don't believe it is very safe in here," said Dave. "This cave must have been formed by that landslide, and, if so, perhaps the dirt and rocks haven't finished settling yet. I don't want any rocks to come down on my head!"

"I kin feel some fresh air from somewhere."
"I feel it too," returned Dave. "Doesn't it come from overhead?"
"Mebbe, lad; although I thought it was ahead."
"Here is that stream of water!" cried Roger, as they made another turn. "But we can't get at it," he added, somewhat disappointedly.
"Why?"
