Chester glanced quickly at his watch.

"Great Scott!" he ejaculated. "Ten o'clock! I had no idea it was so
late."

"Nor I," declared Uncle John.

"Time to get busy, then," said Hal.

"Right," Chester agreed. "We haven't a whole lot of time."

He gazed quickly about the room and then took his position at one side of
the door, where he would not be seen by one entering the room. Hal and
Uncle John also took their places.

"Everything ship-shape?" asked Chester.

"Guess so," replied Uncle John, somewhat nervously--he was not used to
this kind of work, although each lad knew there was no question of his
nerve and courage.

"All set," replied Hal quietly.

"Good!" said Chester. "Now for the disturbance. You fellows will have to
help me out a little."

He raised his voice in a loud shout.

Hal and Uncle John followed suit.
