"What do you mean by running me down?" shouted Tom angrily.

"I—I didn't do it on purpose," returned Andy contritely. "I was seeing how near I could come to you when my steering gear broke. I hope I haven't damaged you."

"My rudder's broken," went on Tom "and I've got to put back to repair it. I ought to have you arrested for this!"

"I'll pay for the damage," replied Andy, and he was so frightened that he was white, in spite of his tan and freckles.

"That won't do me any good now," retorted Tom. "It will delay me a couple of hours. If you try any tricks like that again, I'll complain to the authorities and you won't be allowed to run a boat on this lake."

Andy knew that his rival was in the right and did not reply. The bully and his cronies busied themselves over the broken steering gear, and the young inventor, finding that he could make a shift to get back to his boathouse, turned his craft around and headed for there, in order to repair the damage.

CHAPTER XIV

THE ARROW DISAPPEARS

Paying no heed to the occupants of the bully's boat, who, by reason of their daring, had been responsible for his accident that might have resulted seriously, Tom was soon at his dock. He had it conveniently arranged for hoisting craft out of the water to repair them, and in a few minutes the stern of the ARROW was elevated so that he could get at the rudder.
