"I guess that is our train, Hal," said Chester. "We had better hurry."

The lads retraced their steps toward their train. Reaching the shed, they saw the German officer disappearing into a compartment on the train.

"That looks like our compartment to me," said Hal. "I hope we don't have to ride with him."

"I hope not," agreed Chester, and then broke into a run, as he shouted:

"Hurry! The train is moving!"

It was true. The boys had wasted too much time.

The door to one compartment was all that stood open, and that was the one in which Mrs. Paine could be seen gesticulating to them.

"We just made it," panted Hal, as they reached the open door, and started to climb aboard.

At that instant a uniformed arm appeared through the door and pushed Hal away.

"Go away, you American puppy," came a voice.
