"Not a thing. Coast seems to be perfectly clear. Trees near, too; so we can hide the plane, if you go almost straight down."

Hal followed directions and a moment later the biplane came to rest upon the ground as lightly as a bird.

Hal, Chester and Stubbs climbed out quickly.

"Guess we had better run the machine back among the trees," said Hal.
"Lend me a hand here."

It was the work of but a few moments. Hal walked some distance away and surveyed the spot where the machine had been rolled. He walked around it on all sides.

"O.K.," he said. "You wouldn't know it was there unless you happened to be looking for it."

"Well, what now?" asked Chester.

"Guess we had better don those German uniforms and prowl about a bit."

"Snoop, eh," said Stubbs.

"Now look here, Stubbs," said Hal, "you just keep quiet and get into this uniform we brought along for you."
