in."

"We'll need all that," said Hal. "Now, let's get busy, boys, and see how
near our plan is finished. It's after 10 o'clock, and I'll have to go
pretty soon. If we go, we'll need--"

"Some food," itemized Bud.

"Yes, enough for us and to feed a starving Robinson Crusoe," amended Cub,
beginning the list on a fresh sheet of paper.

"And drinking water."

"No. 2," commented Cub, as he jotted it down.

"And we ought to have a wireless set on hand," Hal suggested.

"Sure," said Cub. "You bring that and your loop aerial. This set is too
big to transfer on board very well."

"That about completes the list, doesn't it?" asked Bud.

"We'll have to have a permit," said Hal.

"Permit for what?" Bud inquired.

"A permit from Mr. Perry to go."

"You're kidding now," said Bud. "Maybe you think this is all a joke."
