Quickly he stooped over, and inserted his fingers in a crack. There was just light enough left from the fast-closing day, to show that the board was loose.

“Look, fellows!” exclaimed the tall lad.

“What is it?” asked Ned.

“This board! I believe we can kick it off and get out!”

“Do it then!” urged Bob.

“No, not now,” said Jerry calmly. “It’s too early, and they’d hear the noise. Wait until after dark, when they’re all in bed, and we’ll escape.”

“But if we do get the board off,” objected Ned, “we’ll only be out in the main room of the carriage house.”

“That’s all right,” declared Jerry. “There are low windows there, and the doors don’t fasten as tightly as this one does. We can get out of the carriage house easily enough, sneak to the airship, and be off before that rascally farmer and his hired men know what’s up.”

“Good!” cried Professor Snodgrass. “I’ll help!”

They could hardly wait for the time to come. It got very dark, for the lantern had been taken away from them. At Jerry’s suggestion they stretched out on the blankets and tried to rest until it should be late enough to make the attempt to escape.
