Tom told the colored man how to find the Swift home, and was debating with himself whether he ought not to offer Eradicate some money as compensation for knocking him into the air, when he noticed that the negro was tying one wheel of his wagon fast to the body of the vehicle with a rope. "What are you doing that for?" asked Tom. "Got to, t' git downhill wid dis load ob fence posts," was the answer. "Ef I didn't it would be right on to de heels ob Boomerang, an' wheneber he feels anyt'ing on his heels he does act wuss dan a circus mule." "But why don't you use your brake? I see you have one on the wagon. Use the brake to hold back going downhill." "'Scuse me, Mistah Swift, 'scuse me!" exclaimed Eradicate quickly. "But yo' doan't know dat brake. It's wuss dan none at all. It doan't work, fer a fact. No, indeedy, sah. I'se got to rope de wheel." Tom was interested at once. He made an examination of the brake, and soon saw why it would not hold the wheels. The foot lever was not properly connected with the brake bar. It was a simple matter to adjust it by changing a single bolt, and this Tom did with tools he took from the bag on his motor-cycle. The colored man looked on in open-mouthed amazement, and even Boomerang peered lazily around, as if taking an interest in the proceedings. "There," said Tom at length, as he tightened the nut. "That brake will work now, and hold the wagon on any hill. You won't need to rope the wheel. You didn't have the right leverage on it." "'Scuse me, Mistah Swift, but what's dat yo' said?" and Eradicate leaned forward to listen deferentially. "I said you didn't have the right leverage." "No, sah, Mistah Swift, 'scuse me, but yo' made a slight mistake. I ain't never had no liverage on dis yeah wagon. It ain't dat kind ob a wagon. I onct drove a livery rig, but dat were some years ago. I ain't worked fo' de livery stable in some time now. Dat's why I know dere ain't no livery on dis wagon. Yo'll 'scuse me, but yo' am slightly mistaken." "All right," rejoined Tom with a laugh, not thinking it worth while to explain what he meant by the lever force of the brake rod. "Let it go at that. Livery or no livery, your brake will work now. I guess you're all right. Now don't forget to come around and do some whitewashing," and seeing that the colored man was able to mount to the seat and start off Boomerang, who seemed to have deep-rooted objections about moving, Tom wheeled his motor-cycle back to the road. Eradicate Sampson drove his wagon a short distance and then suddenly applied the brake. It stopped short, and the mule looked around as if surprised. "It suah do work, Mistah Swift!" called the darky to Tom, who was waiting the result of his little repair job. "It suah do work!" "I'm glad of it." "Mah golly! But yo' am suttinly a conjure-man when it comes t' fixin' wagons! Did yo' eber work fer a blacksmith?" "No, not exactly. Well, good-by, Eradicate. I'll look for you some day next week."
