"Yo' doan't s'pose yo' kin fix dis yeah moah so's I kin use it, does yo', Mistah Swift?" asked Eradicate, not bothering to go into the ethics of the matter. "I reckon now with summah comin' on I kin make mo' with a lawn-moah than I kin with a grindstone--dat is, ef I kin git it to wuk. I jest got it a while ago an' decided to try it, but it won't cut no grass."
"I haven't much time," said Tom, "for I'm anxious to get home, but I'll take a look at it."
Tom leaned his motor-cycle against the fence. He could no more pass a bit of broken machinery, which he thought he could mend, than some men and boys can pass by a baseball game without stopping to watch it, no matter how pressed they are for time. It was Tom's hobby, and he delighted in nothing so much as tinkering with machines, from lawn-mowers to steam engines.
Tom took hold of the handle, which Eradicate gladly relinquished to him, and his trained touch told him at once what was the trouble.
"Some one has had the wheels off and put them on wrong, Rad," he said. "The ratchet and pawl are reversed. This mower would work backwards, if that were possible."
"Am dat so, Mistah Swift?"
"That's it. All I have to do is to take off the wheels and reverse the pawl."
"I--I didn't know mah lawn-moah was named Paul," said the colored man. "Is it writ on it anywhere?"
"No, it's not the kind of Paul you mean," said Tom with a laugh. "It's spelled differently. A pawl is a sort of catch that fits into a ratchet wheel and pushes it around, or it may be used as a catch to prevent the backward motion of a windlass or the wheel on a derrick. I'll have it fixed in a jiffy for you."
Tom worked rapidly. With a monkey-wrench he removed the two big wheels of the lawn-mower and reversed the pawl in the cogs. In five minutes he had replaced the wheels, and the machine, except for needed sharpening, did good work.
