Sam stopped suddenly and dodged back, as Will aimed a blow at him. In doing so he stumbled over a pile of books and went down in a heap.

"Serves you right," said Jack. "Just for his making fun of Will I vote we elect Will as one of the burglars."

The others agreed, even Sam, and Will regained his good nature.

"How about masks?" asked Sam.

"I'll make some," replied Jack, and, from some pieces of black cloth, he quickly cut two false-faces.

"I-I-I-I've g-g-got t-t-t have a g-g-g-g—" came from Will.

"Are you trying to say a pair of gum shoes?" asked John Smith. "I'll lend you a pair of moccasins."

"I guess he means gun," volunteered Nat. "But these will do just as well," and he got a couple of nickel-plated bicycle pumps from a drawer. "They'll shine in the dim light just like revolvers," he went on.

"Guess I'll take a stroll down the corridor and see how the land lies," said Jack. "We don't want to burglarize a room that has no one in it, and they may not be in when the second story men get there."

"That's so, how are we going to get in?" asked Nat.
