“Well, so would I,” declared Andy. “And after all I guess you’re right about taking unnecessary chances. I don’t think I’d like to be in that craft right now.”

But the wind kept falling and as Puss Carberry learned better how to meet each puff of air he manipulated his machine with more success.

“Look, Frank, he’s heading this way! I honestly believe they’re going to fly over our heads! It would be just like Puss and his impudence. I feel like going inside and cheating him out of his laugh.”

But nevertheless Andy did nothing of the kind. His curiosity had been too highly excited, and he was also bent on watching all the crooks and turns made by the advancing biplane, with a view to profiting by the experience of others.

There could be no longer any doubt concerning the design of the two young aviators. The machine was heading straight for the field where Andy had had his hangar built. And presently the biplane was directly over their heads. They could hear the engine humming merrily, while the popping of the unused muffler sounded like the miniature explosion of musketry on a battlefield.

“Hello! caught you napping this time, didn’t we?” called Puss Carberry, as he looked down from his perch, fully eighty feet above their heads.

“Come on up; the sailing’s fine!” mocked Sandy, waving his hand derisively at the two rivals standing there with uptilted heads.

Frank was not possessed of a small nature. He waved back and shouted:

“Fine work, Puss! You’re doing nobly so far; keep it up! We’re going to make a try when the wind goes down. Your biplane looks immense and seems to work in great shape, Bully!”

But Andy said never a word. Truth to tell, he was eating his heart out with envy as he stood there and gaped. For it had been the ambition of his soul that their airship should be the very first ever built in Bloomsbury to navigate the region of the upper currents. And here were the precious pair whom he detested, actually making himself and Frank look like back numbers.
