By this time Wolverton was on his feet, and had recovered his self-possession.

"What right have you to put questions to me, you young whelp?" he demanded, angrily.

"Because I suspect you of designs on my property."

"What do you mean?" snarled Wolverton.

"I will tell you; I think you meant to cut the rope, and send my boat adrift."

"How dare you insult me by such a charge?" demanded the agent, working himself into a rage.

"I have reason to think that you meant to do what I have said."

"Why should I do it?"

"In order to injure me by the loss of my wheat."
