“Sh! In this case we must be careful that we aren’t overheard. There might be some German sympathizer about who would send word of our plans, or, on the other hand, even the federal government agents would interfere if they got wind of our scheme.”

“You are right,” answered the managing editor.

He pressed the electric button on the side of his desk, summoning the young lady secretary from the outer office.

“Miss Bloomfield, is there anyone out there waiting to see me?”

“No, sir.”

“Good! Kindly contrive to knock the big dictionary off your desk the moment anyone comes in, so that I may be warned of any visitors without their knowing it. That is all.” She closed the door.

“Now, boys.”

Ned resumed his explanation.

“The Ocean Flyer is still there in the hangar of the Newark plant of the Universal Transportation Company. Neither Mr. Osborne, president of the company, nor Major Honeywell, the secretary, have any financial interest in the airship. It belongs absolutely to Alan and me, and we intend to use it immediately for the trip to Muhlbruck, where we understand that Bob is awaiting trial.

“The Flyer is in the best of condition and almost ready for use at any moment. All that we need to do is to equip her with a few mechanical supplies, food, firearms, and so on. We can make the trip in less than twenty hours. To-day is Tuesday. If all goes well, we can have Bob back here ready to go out on a city assignment for you by next Monday.”
