med Andy. "He outbid me just out of spite, and I'll
get even with him. You see if I don't!"

Tom looked Andy Foger straight in the eyes, but did not answer, and the
red-haired youth turned aside, followed by his crony, and started
toward his automobile.

"I congratulate you on your bargain," said Mr. Wood as Tom proceeded to
make out a check. He gave little thought to the threat Andy Foger had
made, but the time was coming when he was to remember it well.

CHAPTER III

A TIMELY WARNING

"Well, are you satisfied with your bargain, Tom?" asked Mr. Wood when
the formalities about transferring the ownership of the motor-boat had
been completed.

"Oh, yes, I calculated to pay just what I did."

"I'm glad you're satisfied, for Mr. Hastings told me to be sure the
purchaser was satisfied. Here he comes now. I guess he wasn't at the
auction."

An elderly gentleman was approaching Mr. Wood and Tom. Most of the
throng was dispersing, but the young inventor noticed that Andy Foger
and Sam Snedecker stood to one side, regarding him closely.

"So you got my boat," remarked the former owner of the craft. "I hope

would make.

"I think not," replied Tom. "It's a good name, but I want something
that tells more what a fast boat it is, for I'm going to make some
changes that will increase the speed."

"That's a good idea. Call it the Swift."

"Folks would say I was stuck up if I did that," retorted the youth
quickly. "I think I shall call it the ARROW. That's a good, short
name, and--"

"It's certainly speedy," interrupted Mr. Hastings. "Well now, since
you're not going to use the name CARLOPA, would you mind if I took it
for my new boat? I have a fancy for it."

"Not in the least," said Tom. "Don't you want the letters from each
side of the bow to put on your new craft?"

"It's very kind of you to offer them, and, since you will have no need
for them, I'll be glad to take them off."

"Come down to my boat," invited Tom, using the word "my" with a proper
pride, "and I'll take off the brass letters. I have a screw driver in
my motor-cycle tool bag."

As the former and present owners of the ARROW (which is the name by
which I sha
