“Here comes Jerry, I guess,” Bob said.
“And he’s moving like the wind!” exclaimed Ned.
In a few minutes the dust cloud was nearer, and then the boys saw that it was Jerry approaching at a rapid rate. His machine did not make so much noise now. But, as he came nearer, Bob and Ned, who caught a glimpse of his face, thought he looked a little worried.
“Hold on! Can’t you stop?” cried Bob, for Jerry was about to pass.
“That’s the trouble!” Jerry yelled as he whizzed past. “I can’t seem to shut off the power!”
Then he was lost in a cloud of dust, going down the road in the opposite direction.
“Something’s wrong!” Bob ejaculated.
“He’s forgotten which lever to pull!” exclaimed Ned. “If he don’t look out there’ll be trouble.”
As he spoke Jerry came flying back.
“Can’t one of you do something?” he cried. “I’m afraid to take my hands off the bars long enough to pull the levers again, and the last time I yanked them I seemed to turn on more power. I’ll ride down the road a way and turn back. Think up something in the meanwhile!”
