“Have chairs,” exclaimed the chief. “Sit down and tell me all about it, please.”

“Why,” Andy went on, Frank having motioned to him to do the talking, “this afternoon, as we were taking a spin in our aeroplane, we happened to pass over the woods up near that old Badger shack, and we saw two men lying down in the grass, trying to hide so we wouldn’t notice ’em. It was Jules and Jean, as sure as shooting, and we believe they’re camping in that cabin!”

The police head showed signs of sudden animation.

“Why, boys,” he said, slapping his hand down on his knee, “would you believe it, now. I was just thinking of that old shack when you came in. See, here’s a chart of the whole county and that’s one of the places I had my eye on. But all the same, I’m real glad you came to tell me, boys. Now I’ll feel positive and we can surround the place. Would you like to go along with us tonight, Frank?”

But Frank shook his head in the negative as he replied:

“Thanks, but I guess we’ve got all the work cut out for us we can handle, chief. We believed you’d want to keep it a secret, for fear that they had some friends in town who might carry a warning. But we’ll move on now. Hope you have success and make a haul. Come on, Andy, let’s get back home!”

CHAPTER XX.
THE AEROPLANE RACE.

“Frank, we’re in great luck!”

“I think so myself, Andy,” replied the taller of the cousins, as he coolly bent down to adjust some little thing about the engine of the monoplane.

“Here it’s past noon on the great day! Six thousand good people have gathered on the field here and on the neighboring fences just to see us fly, and there isn’t a mite of wind. I say it’s the greatest luck ever,” and Andy, who was bubbling all over with enthusiasm, turned to look around at the vast throngs.
