"We'll hire Eradicate Sampson to stand guard with a bucket of whitewash. He'll keep the boys away."
The plan was put into operation, and Eradicate and his mule, Boomerang, were installed on the premises.
"Deed an' Ah'll keep dem lads away," promised the colored man. "Ah'll splash white stuff all ober 'em, if dey comes traipsin' around me."
He was as good as his word, and, when one or two lads had received a dose of the stuff, which punishment was followed by more severe from home, for having gotten their clothes soiled, the nuisance ceased, to a certain extent. Sam Snedecker and Pete Bailey were two who received a liberal sprinkling of the lime, and they vowed vengeance on Tom.
"And Andy Foger will help us, too," added Sam, as he withdrew, after an encounter with Eradicate.
"Doan't let dat worry yo', Mistah Swift!" exclaimed the darkey. "Jest let dat low-down-good-fo-nuffin' Andy Foger come 'round me, an' Ah'll make him t'ink he's de inside ob a chicken coop, dat's what Ah will."
Perhaps Andy heard of this, and kept away. In the meanwhile Tom kept on perfecting his car and battery. From the club secretary he learned that a number of inventors were working on electric cars, and there promised to be many of the speedy vehicles in the race.
After considerable labor Tom had succeeded in getting together one set of the batteries. He had them completed one afternoon, and wanted to give them a test that night. But, when he went to his father's chemical laboratory for a certain powder, which he needed to use in the battery solution, he found there was none.
"I'll have to ride in to Mansburg for some," he decided. "I'll go after supper, on my motor-cycle, and test the battery to-night."
The young inventor left his house immediately after the evening meal. Along the road toward Mansburg he speeded, and, as he came to the foot of a hill, where once Andy Foger had put a big tree, hoping Tom would run into it and be injured, the youth recalled that circumstance.
