"Sho! we wouldn't know the wing feather of a plane from one that belonged in the tail or steering rudder," chuckled Larry.

"But I'm meaning to learn, Frank," put in the small chap, strenuously. "It looks so easy for you fellows, knocking around up there, with nobody ever getting in your way, like on our roads, that I want to fly."

"Well," pursued Frank, shaking his head. "I don't encourage anybody to take up the business. It's certainly the most dangerous calling going at present; but after the Wrights have put their latest balancing idea into general use, the number of dead aviators will drop fast. In time it may be a fellow can hardly fall out of a well-made flying machine if he is the most reckless aviator going."

"Hear that, Elephant," laughed Larry. "Hope yet that some of us common truck may be flapping through the upper currents, and getting out of the wet when it rains, by sailing above the clouds. But I see some fellow coming along the road on his wheel like he had a hurry call. Looks like Nat Holmes too, and he's coming in here."

"Funny how badly balanced that fellow is," remarked Frank. "Always in a hurry in everything he tackles; and then falling all over himself when he tries to talk. He's waving his hat too like he had something interesting to say. Let's hope, boys, it happens to be one of his good hours; or we're in for a lot of gibberish Hottentot patter, I'm afraid."

CHAPTER IV

SUSPICION

"F-f-frank!" stammered the new arrival, as he actually fell off his wheel, allowing the same to drop in a heap on the turf.

"That's me; what d'ye want, Nat?" asked the one addressed; as he assumed a reassuring air, knowing what a terrible mess the wretched stutterer often made of his attempt at speech, especially when he happened to be excited.

Nat was breathing hard. He always did things with a whirlwind method; and of course the exertion added to his difficulty in forming such words as he wanted.
