But Dick's engine was not directly connected to the propellers. There was a clutch arrangement, so that the motor could be started, with the propellers out of gear, and they could be "thrown in," just as an automobile is started. This gave greater flexibility, and also allowed for the reversing of the propellers to make a quick stop.

And it was not necessary for Dick to "crank" his motor. An electric self-starter did this for him, though in case of emergency the engine could be started by hand.

In fact everything aboard the Abaris was most up-to-date, and it was on this that Dick counted in winning the big prize.

"Well, I guess everything is as ready as it ever will be," remarked the young millionaire, as he and the aviator made a final inspection of the craft. "Get aboard, fellows!"

"He's as cheerful about it as though he were inviting us to a hanging," laughed Paul.

"Oh, I'm not worrying about any accident," said Dick quickly. "I'm only afraid we've made her too big and won't get any speed out of her. And speed is what's going to count in this trans-continental flight."

"She'll be speedy enough," predicted Mr. Vardon, with a confident air.

Paul, Innis, Larry and Mr. Vardon entered the cabin. Then Dick went in, followed by Jack Butt, who remained to tighten a guy wire that was not just to his satisfaction.

"Well, are we all here?" asked Dick, looking around.

"Yes," answered Paul, and there was a note of quiet apprehension in his voice. Indeed it was rather a risk they were all taking, but they had confidence in Mr. Vardon.
