Captain Turton went ashore at the first port they made, after leaving Detroit, and when he came aboard again, he sought out Nat. The captain's manner betrayed some excitement.
"I have some news for you," he said to the young pilot.
"Am I going to be arrested again?"
"Not exactly. This concerns your enemy, Bumstead."
"Have they got him? Did he give up the money?"
"No, but I heard from a captain friend of mine ashore a little while ago, that the Spray is docked at Cove Point, about fifty miles above here. She had to lay up for repairs. She's an old boat and her engines are continually getting out of order."
"Are we going to stop there?" asked Nat eagerly.
"No, but I know what you are thinking of. There is a chance to cause the arrest of the mate, and here is my plan. You can take a train from here to Cove Point. The railroad runs quite near there. You have the warrant, made out by the police. Take that with you, and the authorities in Cove Point will make the arrest, I'm sure."
"But how can I get back to this boat?"
"I'll tell you. There is a train that leaves here at midnight, which will get you to Cove Point about two o'clock in the morning. The police are up at all hours. You can get them to serve the warrant at once, for Bumstead will probably be aboard the Spray at her dock. Then, after he is safe in jail, you can hire a boat to take you out, and I'll pick you up as I pass. I'll be on the watch for you to-morrow morning."
