Snow listened with interest.

“Wonderful!” he cried, as Frank finished; “it is wonderful!”

Then he sprang to his feet and paced the deck excitedly. Frank was, of course, not a little surprised.

But Captain Uriah suddenly recollected himself and paused.

“Pardon me!” he exclaimed. “I was so deeply engrossed that I quite forgot myself. There is a matter upon my mind which I must broach to you. It is a great project, and I know I shall have your co-operation.”

“Indeed!” was all Frank could say.

“No doubt I surprise you; but I am very much in earnest. It is a scheme which I have been some years in bringing about. But its safe consummation will certainly bring me a great fortune. This I will willingly share with you.”

Frank was interested.

“I should be pleased to know of your project,” he said.

“Good! I knew that I would get your interest. The fact that you have a submarine boat makes me feel perfectly sure of success.”
