"What do you want, Mr. Wolverton?" asked Bob, coolly, as he stood at one end of the boat and surveyed the excited agent.

"Come ashore, or I'll have you arrested," shouted the irate Wolverton.

"You are very kind, Mr. Wolverton; but I am in considerable of a hurry, and have not time to comply with your request."

"You'd better come ashore, if you know what's best for yourself."

"Please state your business! If it is anything to my advantage, I may come; but I am just ready to start for St. Louis."

"Is my nephew Sam on your boat?"

"I don't see him. Why should he be on board?"

"I suspect him of running away, the ungrateful young rascal? I thought he might be scheming to go down the river with you."

"Clip," said Bob, gravely, "has Sam Wolverton engaged passage with us?"

"Not as I knows on, Massa Bob."
