“Unless you go in for that $50,000 prize,” cried Billy skillfully evading the playful blow Frank aimed at him. “In all seriousness, Frank, won’t you?” he pleaded.

“In all seriousness, no,” was Frank’s rejoinder. “I’d like to do it. Billy,” he went on. “I’d like to do it for your sake, if it would do you any good—we both would, wouldn’t we, Harry?”

“You bet,” replied the younger brother with effective brevity.

“Well, of course, I know you fellows too well to try to urge you,” said Billy; “but I would like to be able to announce in the Planet to-morrow that the Boy Aviators announce they will compete for the paper’s big prize.”

“To tell you the truth, Billy,” laughed Frank, “we’ve had about enough newspaper notoriety lately. It’s mighty good of you to write accounts of our adventures, but I guess the papers can get along for a while without anything about us.”

“Not at all, you make good copy,” declared Billy, with such comic emphasis that the boys went off into shouts of laughter.

And so it came about that Billy said good-night without having shaken the Boy Aviators in their determination not to engage in any public flights, but all the time, though they little knew it, events were so shaping themselves that little as they dreamed it they were to take part in the record flight.

UNDER A CLOUD.

It was early the next morning. The paper had been put to bed. Billy, with the satisfied feeling that came to him with the knowledge that he had written a good introduction and account of the Planet’s great offer, was slipping into his coat preparatory to going home, when Mr. Stowe, his face purple with anger, called to him in a sharp voice from the door of the editorial sanctum.

“Come here, Barnes, I want to see you,” he said brusquely.
