"But I must tell you, Joe. Your father's patent rights are again in danger. Rufus Holdney is going to try to get some valuable papers and models away from him. That's what he and I quarreled over. I'd do anything to spoil his plans, after he has thrown me off as he has. I left him, and since then I have had only bad luck. I don't know how I came to come here. I didn't know you were here. But warn your father, Joe, to look well after his new patents. Warn him before it is too late."
