“Yes, sir,” nodded the radiant inventor.

“That’s $2,160,000!” gasped the old man.

“Your figures are correct, sir,” said Captain McGill dryly; “and the nation owning such boats gets them cheap, in my opinion.”

“Lockyer!” cried the old man, approaching the inventor with outstretched hand, “I have been unjust to you in the past. Forgive and forget. For my part, after what I have seen, I am willing to admit that submarines, besides being needful in war, have occasions of usefulness in peace.”

“Their lawful occasions, eh?” quoted Lieutenant Parry, from the sea service.

“The Lockyer has proved that twice,” put in Mr. Stark.

“Parry, what’s the nearest harbor? It’s important that we should land those rascals and the Italians, and give them into the hands of the police,” said Captain McGill presently.

“We can make for Stonington, sir,” was the reply. “There’s Fisher Island light off our port-bow now.”

“Then put us in there. It will be daylight in a short time,” ordered Captain McGill. “Strong, you, Taylor and Marlin will remain on board as a prize crew. Mr. Lockyer,” this with a smile at the inventor and the girl, “you will also remain to take care of your own particular prize. Gentlemen, let us re-embark on board the latest addition to the United States Navy—the submarine wonder, the Lockyer.”
