“Huh! he’s doing pretty well, I admit,” he said, grumblingly. “But wait till you get going and then he’ll just have to take a back seat. I believe a monoplane is more like a real bird than any of the other types. Ain’t it nigh time, Frank, for you to get a move on? I don’t reckon I can stand this much longer.”

Frank smiled. With two against one it began to look as though he must speedily capitulate. There was Andy keeping a pair of hungry eyes glued upon him and with a look of mute entreaty in his blue eyes.

Frank raised his hand to feel the air, gave one more look all around, drew in a long breath and then turning to his comrade he nodded his head.

“Do we start?” demanded the other, eagerly.

“It is time!” was Frank’s simple reply, as he stepped over to where the little monoplane awaited the coming of its makers.

CHAPTER XVI.
SEVEN TIMES AROUND THE CIRCLE.

Frank knew full well that he was about to start upon the most risky thing that he had ever undertaken thus far in his whole life.

Many a skilled aviator would hesitate to take up a second person with him in a monoplane. True, in building the machine they had figured on this matter. And there was now a dead calm, which made matters easier for the novice. Then again, Frank was perfectly cool and not apt to lose his head under the most trying conditions.

He had studied these things closely. He had visited the aviation field more than once. And while thus far he had kept the matter a dead secret, even from his chum, Frank had himself been up in an aeroplane for a little swing around the field at the time of his visit to Long Island. So that if it was true that Puss Carberry had passed through this experience he was but following in the wake of his rival.

Frank knew what must be done. He saw that Andy was fixed in his seat and gave him last words of advice. Everything was now ready for the start. And Frank was secretly glad that the biplane had dropped out of sight again, because he did not wish to have his attention distracted from the work in managing his eccentric steed of the air.
