“Whoever they are, or whatever they may try to do, we’re not going to let a phone call scare us out of this effort to save Bob Russell,” said Ned. “We’re all ready to start now except for getting the Herald’s permission to let Buck here go with us. He can see the managing editor about that the first thing in the morning, and then we’ll be off immediately.

“But if this gang really has you boys spied upon, they will certainly make some attempt to stop you,” argued Major Honeywell.

“Nobody stands any chance of stopping us once we get up in the air,” answered Ned, “but, as you say, we may as well try to make our get-away as secretly as possible. I would suggest that instead of starting out by daylight to-morrow, as we planned, that we wait until midnight. Each of us can leave his house at a different time during the day and go about as if we have changed our minds and called the trip off. Then, just in time to reach the Newark factory, each one can start off alone. We should be able to disarm any suspicion in that way.”

Everybody approved heartily of Ned’s scheme and parted that night with a little more earnestness in their handshakes than usual. All of the road back home the Airship Boys cast furtive glances over their shoulders every now and then, but no sign of any followers was visible.


CHAPTER VI
ESCAPING FROM DEADLY SHADOWS

Alan Hope spent most of the next day at the offices of the Universal Transportation Company, and was inclined to scoff at the idea of his being watched. Nevertheless he had a loaded automatic revolver tucked away in his hip pocket, and, as night drew on, his assurance began to ooze gradually, and he felt more than once to make sure that his weapon was still there ready for defense.

Ned Napier was really impressed with the threats of the mysterious German, and, though he did not arm himself as Alan had, he kept a sharp lookout for suspicious characters about him. All day long he wandered with an air of affected carelessness through the downtown shopping district, made a couple of short business calls, ate leisurely at the Ritz, and seemed to have no thought of anything but home and bed for that evening.

Buck Stewart arose early that morning, ate a hearty breakfast, and when he started out took with him what was apparently an ordinary cane, but which really was a rod of steel, encased in leather. Many reporters carry them when they are sent out on assignments into dangerous sections of the city.

Swinging his stick jauntily, he made his way first to the offices of the Herald, where a brief chat with the managing editor readily procured him permission to accompany the Airship Boys on their trip. The editor, in fact, made a regular assignment of it and cautioned Buck to take along with him plenty of pencils, notebooks and a small camera that could be swung over one shoulder with a strap.
