"How come?"

"I mean it in this way. Sometimes when you can't solve a problem it's very easy to prove that it can't be solved by anyone. That's what I can prove now, but why waste time?"

"Have we got anything special to do with our time?" asked Ronicky dryly.

"Well, my proof is easy. Here we are in hard-pan dirt, without any sort of a tool for digging. So we sure can't tunnel out from the sides, can we?"

"Looks most like we can't," said Ronicky sadly.

"And the only ways that are left are the ends."

"That's right."

"But one end is the unfinished part of the tunnel; and, if you think we can do anything to the steel door—"

"Hush up," said Ronicky. "Besides, there ain't any use in you talking in a whisper, either. No, it sure don't look like we could do much to that door. Besides, even if we could, I don't think I'd go. I'd rather take a chance against starvation than another trip to fat Fernand's place. If I ever enter it again, son, you lay to it that he'll get me bumped off, mighty pronto."

Jerry Smith, after a groan, returned to his argument. "But that ties us up, Ronicky. The door won't work, and it's worse than solid rock. And we can't tunnel out the side, without so much as a pin to help us dig, can we? I think that just about settles things. Ronicky, we can't get out."
