“I keep my eye on him. Dat boy,” announced Scipio, “remind me of mean, low-down people, I meet afore in my ’sperience. Bimeby I watch him bend towards de door. He seemed listening. Den I saw him start and draw closer to de door. Den all of a sudden he make a rush out of de place. I run to de gate. Den anoder sneaking-looking boy meet him. Dey talk fast, berry much excited. Den dey make a run towards the railroad tracks as if dey was in a turrible hurry.”

“Dale Billings and Gus Talbot!” exclaimed Andy, on fire with the intelligence imparted by his loyal, dusky friend. “Silas, they have got our secret. They are after the old leather pocketbook on the Collins farm. We must get there first!”

Andy directed Silas to wait where he was. Then he ran to the room where Mr. Parks was engaged with his friends. Appearing at the doorway he attracted the attention of the aeronaut and beckoned to him.

“What is it, Andy?” inquired Parks, coming outside. “You look excited.”

“I am,” admitted Andy, and then very briefly, but clearly, he explained his urgency.

“I say, you mustn’t let any grass grow under your feet!” exclaimed Parks. “I reckon you’ve got it right—that sneaking fellow you was trying to help is off on the track of the old shed you tell about. There’s the Racing Star—no, that won’t do, but—I’ve got it, Andy. Wait here a minute.”

John Parks flashed in among his friends and then flashed out again. Now he was accompanied by a well-dressed portly gentleman whom Andy had seen about the aviation grounds, and whom he knew to be one of the principals in getting up the race.

The aeronaut was busy talking fast and urgently to this person, who nodded to Andy and said:

“That’s all right Do you know how to run an automobile?” to Andy.

“Why, that was his old business,” explained Parks.
