The young inventor quickly stepped to one side, and, as the bully passed him, Tom sent out a neat left-hander.  Andy Foger went down in a heap on the grass.

CHAPTER V

A TEST OF SPEED

Whether Tom or Andy was the most surprised at the happening would be hard to say.  The former had not meant to hit so hard and he certainly did not intend to knock the squint-eyed youth down.  The latter’s fall was due, as much as anything, to his senseless, rushing tactics and to the fact that he slipped on the green grass.  The bully was up in a moment, however, but he knew better than to try conclusions with Tom again.  Instead he stood out of reach and spluttered: 

“You just wait, Tom Swift!  You just wait!”

“Well, I’m waiting,” responded the other calmly.

“I’ll get even with you,” went on Andy.  “You think you’re smart because you got ahead of me, but I’ll get square!”

“Look here!” burst out the young inventor determinedly, taking a step toward his antagonist, at which Andy quickly retreated, “I don’t want any more of that talk from you, Andy Foger.  That’s twice you’ve made threats against me to-day.  You put that log across the road, and if you try anything like it for your second attempt I’ll make you wish you hadn’t.  That applies to you, too, Sam,” he added, glancing at the other lad.

“I—­I ain’t gone’ to do nothin’,” declared Sam.

“I told Andy not to put that tree—­”

“Keep still, can’t you!” shouted the bully.  “Come on.  We’ll get even with him, that’s all,” he muttered as he went back into the bushes where the auto was.  Andy cranked up and he and his crony getting into the car were about to start off.

“Hold on!” cried Tom.  “You’ll take that log from across the road or I’ll have you arrested for obstructing traffic, and that’s a serious offense.”

“I’m goin’ to take it away!” growled Andy.  “Give a fellow a show can’t you?”

He cast an ugly look at Tom, but the latter only smiled.  It was no easy task for Sam and Andy to pull the log out of the way, as they could hardly lift it to slip the rope under.  But they finally managed it, and, by the power of the car, hauled it to one side.  Then they speed off.

“I ‘clar t’ gracious, dem young fellers am most as mean an’ contrary as mah mule Boomerang am sometimes,” observed Eradicate.  “Only Boomerang ain’t quite so mean as dat.”

“I should hope not, Rad,” observed Tom.  “I’m ever so much obliged for your warning.  I guess I’ll be getting, home now.  Come around next week; we have some work for you.”

“‘Deed an’ I will,” replied the colored man.  “I’ll come around an’ eradicate all de dirt on yo’ place, Mistah Swift.  Yais, sah, I’s Eradicate by name, and dat’s my perfession—­eradicatin’ dirt.  Much obleeged, I’ll call around.  Giddap, Boomerang!”
