CHAPTER I

A MOTOR-BOAT AUCTION

"Where are you going, Tom?" asked Mr. Barton Swift of his son as
the young man was slowly pushing his motor-cycle out of the yard
toward the country road. "You look as though you had some object
in view."

"So I have, dad. I'm going over to Lanton."

"To Lanton? What for?"

"I want to have a look at that motor-boat."

"Which boat is that, Tom? I don't recall your speaking about a
boat over at Lanton. What do you want to look at it for?"
