The fact that no one was allowed in Fritz's workshop unless he accompanied them, and the additional fact that at night two soldiers were stationed at the door at first caused the boys some surprise. However, Fritz had explained:
"You see, the government has taken over all aircraft in process of construction, no matter how crude and amateurish, and has appointed a commission to investigate all patents. Of course, it was known that I was building an airship, and, as a result, I am working under government orders.
"If my craft should come up to expectations it will mean a great deal to me, and I probably shall either be put to work building more, or, better still, be made a member of one of the aeroplane corps."
"Yes," said Chester again, "Fritz is a fine fellow. Do you suppose his aeroplane will be a success?"
"I don't know. For his sake, I hope so. As he says, it means a whole lot to him."
"So do I. And I will bet Fritz would be of great help to his country. He is a pretty shrewd chap."
"You bet he—Hello! What's that?"
A sudden cry had come from the direction of the kitchen, and the sounds of a struggle followed.
"Come on!" shouted Chester. "Somebody is in trouble!"
The two boys ran madly around the house.
