"Why, I am glad to find you at leisure, and willing to be amused," smiled Captain Jack, quietly. "Will it be too much like business if I ask you down to the water to watch a little demonstration that we want to make with the 'Pollard'?"
"Is it something brand-new?" laughed Mr. Farnum, resting an arm on the young captain's shoulder.
"So far as I know, it's shiningly new," laughed Jack Benson.
"What is it?"
"If you don't mind, Mr. Farnum, I'd rather show it to you first."
"How long will the demonstration take?"
"It ought not to require more than fifteen or twenty minutes, sir."
"I'll take you up, then," agreed Mr. Farnum, pleasantly.
Just at that moment the inner door opened. Mr. Melville came out, followed by his lawyer, Don bringing up the rear of the file.
"I guess you'd better come along with me, gentlemen," called Mr. Farnum. "Captain Benson has just invited me to witness something new in the submarine line."
