Messrs. Farnum and Pollard, Jack and Hal made up the visiting party, leaving Eph Somers aboard the submarine, with Williamson to help him at need.

Cordial, indeed, was the reception of the submarine folks aboard the gunboat. There was a great amount of handshaking to be done.

In the meantime, Eph Somers was having something in the way of trouble back on the platform deck of the "Benson."

Two small boats, manned by harbor boatmen, and each carrying a few passengers, had put off from shore, and now ranged alongside.

"How do you do, Captain?" shouted a young man at the bow of one of the boats.

"Louder!" begged Eph.

"How do you do, Captain?"

"Louder. I'm afraid the captain can't hear you yet," grinned the carroty-topped submarine boy. "He's over on the gunboat."

"Then who are you?"

"Who? Me?" demanded Eph, innocently. "Oh, I'm only the Secretary of the Navy."
