sn't even got that far, as yet. It's all up in the air, so
to speak. I'll tell you in due season. But, speaking of the air, let's
go for a spin. It may drive some of the cobwebs out of my brain. Did I
hear you say you thought it would rain?"

"No, it's as clear as a bell. I said I hoped it wouldn't rain for the
sake of the soldiers in camp. They've had their share of wet weather,
and, goodness knows, they'll get more when they get to Flanders. It
seems to do nothing but rain in France."

"It is damp," agreed Tom. "And, come to think of it, they are going to
have some airship contests over at camp to-day--for the men who are
being trained to be aviators, you know. It just occurred to me that we
might fly over there and watch them."

"Fine!" cried Mr. Damon. "That's the very thing I should like. I'll
take a chance in your Hawk, Tom, if you'll promise not to try any
spiral stunts."

"I promise, Mr. Damon. Come on! I'll have Koku run the machine out and
get her ready for a flight to Camp. It's a good day for a jaunt in the
air."

"Get out the Hawk, Koku," ordered the young inventor, as he motioned to
a big man--a veritable giant--who nodded to show he understood. Koku
was really a giant, one of a race of strange beings, and Tom Swift had
brought the big man with him when he escaped from captivity, as those
will remember who have read that book.

"Going far, Tom?" asked an aged man, coming to the door of one of the
many buildings of which the shed where the airship was kept formed one.

"Not very far, Father," answered the young inventor. "Mr. Damon and I
are going for a little spin over to Camp Grant, to see some aircraft
contests among the army birdmen."

"Oh, all right, Tom. I just wanted to tell you that I think I've gotten
over that difficulty you found with the big carburetor you were working
on. You didn't say what you wanted it for, except that it was for a
heavy duty gasolene engine, and you couldn't get the needle valve to
work as you'd like. I think I've found a way."

"Good, Dad! I'll look at it when I come back. That Carburetor did
bother me, and if I can get that to work--well, maybe we'll have
something soon that will--"

But Tom did not finish his sentence, for Koku was getting the aircraft
in operation and Mr. Damon was already taking his place behind the
pilot's seat, which would be occupied by Tom.

"All ready, are you, Koku?" asked the young inventor.

"All ready, Master," answered the gi
