“Oh, we won’t have to remain here that long,” said Laura, cheerfully.

“Hope not,” growled Bobby. “I’m getting hungry.”

“That won’t do you any good,” said Jess. “It’s useless to have an appetite when there is nothing in sight to satisfy it—just as useless as the holes in a porous plaster.”

“Who says the holes in a porous plaster are useless?” demanded Bobby, quickly. “They’re not.”

“What are they for, then?” asked Eve, mildly.

“Why, to let the pain out, of course,” declared Bobby, boldly.

“I wish there were some holes here that would let us out,” sighed Nellie Agnew.

“Don’t lose heart, Nell!” advised Laura. “There never was a situation that didn’t offer some release. We’ll find a way of escape.”

“Sure!” scoffed Bobby. “Any of us can crawl out through one of these slits in the wall.”

“And then what?” demanded Jess.
