“Hey! Hello, down there!” came a hail from almost directly above.

“Hello yourself!” answered Frank, without looking up.

“Managed to get a move on, did you?” pursued Puss, as he held in his biplane so that he could sail along not fifty feet away from the other aircraft.

No doubt he was eagerly sizing the monoplane up the while and making a mental calculation as to what chances there would be of her giving him a stiff race.

“Why don’t you get up where you can see something?” called out Sandy, when neither of the others had replied to the remark of his companion.

“Oh, this is good enough for us the first time. When we get used to the feeling you’ll see us climb!” said Frank, pleasantly.

“Huh! guess you’re afraid, that’s what,” jeered Sandy.

“Perhaps you’re right Sandy,” replied Frank. “This is a queer business for a green-horn, and I’m not anxious to break my neck in the start. Give us a little time and we’ll show you what this machine can do.”

“Well, by-by then,” called Puss. “We can’t bother with such a slow coach. But if you don’t get along better than that the race is sure going to be a walk-over.”

“You just wait and see. The fellow laughs loudest who laughs last!” shouted Andy, who could hold in no longer.
