Half a dozen policemen were gathered about the end nearest the float which upheld the Sea Lion, and the figure of another showed at the top of the conning tower. As the police wagon dashed up to the wharf another rig came up on a run and halted close at the side of it.

"Hello," called the chief, recognizing a man on the seat, "how did you manage to get here so soon?"

"Some one 'phoned for me," was the hurried reply. "Where is the dead man?"

"In the submarine," answered an officer who had drawn closer to the official's buggy.

Without another word the newcomer leaped out and was conveyed to the
Sea Lion in the rowboat Ned had left tied to the wharf.

"That's the Coroner," the chief said, in explanation. "He'll soon get at the bottom of this."

"Suppose we get aboard the Sea Lion," suggested Ned.

"Of course," said the chief, "you'll remain here a few days and assist in the capture of this fellow?"

"I shall have to ask for instructions from Washington," was the reply. "I really ought to get away on the steamer which sails in the morning."

When the three, using a boat an officer found nearby, reached the main cabin of the Sea Lion they found Jack and Frank sitting by the table, handcuffed, repeating over and over again their individual and collective opinion of the police of Vallejo. Jimmie seemed to take great delight in taunting them.
