"And I will write some letters to my lawyers in Washington and ask their advice." It took Tom the remainder of that day, and part of the next, to arrange the gasolene and spark control of his machine to his satisfaction. He had to make two small levers and some connecting rods. This he did in his own particular machine shop, which was fitted up with a lathe and other apparatus. The lathe was run by power coming from a small engine, which was operated by an engineer, an elderly man to whom Mr. Swift had given employment for many years. He was Garret Jackson, and he kept so close to his engine and boiler-room that he was seldom seen outside of it except when the day's work was done.

One afternoon, a few days after the unsuccessful chase after the fugitive had taken place, Tom went out for a spin on his motor-cycle. He found that the machine worked much better, and was easier to control. He rode about fifteen miles away from home, and then returned. As he entered the yard he saw, standing on the drive, a ramshackle old wagon, drawn by a big mule, which seemed, at the time Tom observed him, to be asleep.

"I'll wager that's Boomerang," said Tom aloud, and the mule opened its eyes, wiggled its ears and started forward.

"Whoa dar, Boomerang!" exclaimed a voice, and Eradicate Sampson hurried around the corner of the house. "Dat's jest lake yo'," went on the colored man. "Movin' when yo' ain't wanted to." Then, as he caught sight of Tom, he exclaimed, "Why, if it ain't young Mistah Swift! Good lordy! But dat livery brake yo' done fixed on mah wagon suttinly am fine. Ah kin go down de steepest hill widout ropin' de wheel."

"Glad of it," replied Tom. "Did you come to do some work?"

"Yais, sah, I done did. I found I had some time t' spah, an' thinks I dere might be some whitewashin' I could do. Yo' see, I lib only 'bout two mile from heah."

"Well, I guess you can do a few jobs," said Tom. "Wait here."

He hunted up his father, and obtained permission to set Eradicate at work cleaning out a chicken house and whitewashing it. The darky was soon at work. A little later Tom passing saw him putting the whitewash on thick. Eradicate stopped at the sight of Tom, and made some curious motions.

"What's the matter, Rad?" asked the young inventor.

"Why, de whitewash done persist in runnin' down de bresh handle an' inter mah sleeve. I'm soakin' wet from it now, an' I has t' stop ebery onct in a while 'case mah sleeve gits full."
