This, then, is what Dick did. He would let the airship shoot downward on a long slant, so as to gain as much as possible. Then, by throwing up the head-rudder, he would cause his craft to take an upward turn, thus delaying the inevitable descent.

All the while this was going on Mr. Vardon, aided by Lieutenant McBride, was laboring hard to replace the burned-out wires. He worked frantically, for he knew he had but a few minutes at the best. From the height at which they were when the motor stopped it would take them about ten minutes to reach the earth, holding back as Dick might. And there was work which, in the ordinary course of events, would take twice as long as this.

"I'm only going to make a shift at it," explained the aviator. "If I can only get in temporary wires I can replace them later."

"That's right," agreed the army man.

"How you making it, Dick?" asked Larry, as he came to the door of the pilot-house.

"Well, I've got five hundred feet left. If he can't get the motor going before we go down that far—"

Dick did not finish, but they all knew what he meant.

"Another second and I'll have the last wire in!" cried Mr. Vardon. "Do your best, Dick."

"I'm doing it. But she's dipping down fast."

"Oh, for a dirigible balloon now!" cried the lieutenant. "We could float while making repairs."
