"They're welcome," jeered Egbert Lawton. "As it happened, my wife had some sort of presentiment, and the jewels are in two canvas pouches securely fastened under her clothing. She leaped overboard with them."

As the "Pollard" now ran much closer, those aboard the submarine could hear the yells of rage that came from the yacht's cabin.

"The safe was unlocked, and the rascals have found out how badly they've been sold," laughed Mr. Lawton. "But why are you going so close to the yacht? In their rage, they'll fight like fiends, and you are unarmed."

"We shall see what we shall see," dryly commented the commander, murmuring a few words in Hal Hastings's ear.

Hal promptly dropped down below.

"Selma ahoy!" hailed Ennerling, when the submarine was once more up with the yacht.

"Get quiet and go to sleep!" shouted back the leader of the mutineers, derisively.

"Under the law you mutineers are pirates," shouted back the commander, firmly. "If you don't surrender we shall be compelled to sink you."

"Sheer off and forget it!" jeered the mutineer.

"Look here, my man," bellowed Commander Ennerling, "we'll have no further nonsense from you. Surrender, without further parley, or you'll find our nose pointing at your side hull—and then there'll be some fireworks. You can't be insolent with the United States Navy."
