"Take it quietly," Ned advised Jimmie, as the little fellow began struggling with the arm of the law. "We'll come out on top in the end, I take it."

"I'd like to knock the head off this fool cop!" Jimmie cried. "What right has he to go an' arrest us?"

"If it will take any load off your mind," the policeman replied, as the three waited on a corner for a patrol wagon, "I'll tell you what right I had to arrest you. There's a report at the office that a man who went into that submarine of yours never came out again."

"When was this report sent in?" asked Ned.

"Just a few moments ago," was the reply. "All the officers in the city are either watching for you or heading toward the boat. What have you done with Lieutenant Scott?"

"Who sent in the report?" asked Ned.

"I don't know his name, but the chief does. He says he went to the water front, on the island side, with the Lieutenant, that the Lieutenant went on board the Sea Lion with you and the others, and that he has not been seen since. What about it? Better confess and get an easy sentence."

"The officers who are on their way to the submarine will find out why the Lieutenant never came out," Ned said. "But about this man who made the report. Why was he waiting for Scott to leave the boat?"

"Said he had an understanding with him that he was to watch outside, as Scott did not exactly trust you New York kids. A little while ago he heard a commotion and calls for help on board, so he came up to report."

"Thank you for the information," Ned said. "Now, you can't get us to headquarters any too quickly."
