"You are a fool, young man! I am inclined to think, also, that you are out of your head."

"If you had any other purpose, what is it?"

Wolverton bethought himself that in order to avert suspicion, he must assign some reason for his presence. To do this taxed his ingenuity considerably.

"I thought I saw something in the water," he said. "There it is; a twig; I see now."

"And what were you going to do with the razor?"

"None of your business!" said Wolverton, suddenly, finding it impossible, on the spur of the moment, to think of any reason.

"That is easy to understand," said Bob, significantly. "Now, Mr. Wolverton, I have a warning to give you. If anything befalls my boat, I shall hold you responsible."

"Do you know who I am?" blustered Wolverton. "How do you, a boy, dare to talk in this impudent way to a man who has you in his power?"

"It strikes me, Mr. Wolverton, that I hold you in my power."

"Who would believe your unsupported assertion? sneered the agent."
