"All just as it ought to be," hailed Hal, blithely. "Don't be at all afraid, madam. Porpoise is my middle name, and you can't sink while I have you."

The work of the two Naval officers who had plunged overboard was easier.

Both of the men who had leaped from the yacht's stern rail were able to swim. Briscoe and McCrea merely reached them and swam alongside.

David Pollard had ropes over the side of the submarine in a jiffy. It was easy work for seafaring men to climb these ropes over the sloping, easy side. It was scarcely more difficult to get the women up in safety.

"Let the ladies go below to the port stateroom," called Mr. Farnum.

"They can disrobe, rub down and get in between blankets in the berths.

Their men folks can take care of 'em."

"I'm the steward, sir, of the 'Selma,' the yacht that's ahead," explained the man in white duck. "I'll help them below at once, sir."

"We can have hot coffee in seven minutes," Mr. Farnum continued.

"Captain Benson, if you'll take the wheel again, I'll go below and get to work in the galley."

The white-haired man, in the meantime, was hurriedly making himself known to Commander Ennerling as Egbert Lawton, owner of the "_Selna_,"

a hundred-and-forty-foot schooner rigged steam yacht. The ladies were his wife and his sixteen-year-old daughter, Miss Ethel Johnson was the steward's name.

"Get after the yacht again, Captain Benson," requested Commander Ennerling. "We have the owner and the ladies safe, but we've got to take that crew to land as mutineers."

"They'll fight to the last shot," declared Mr. Lawton, shaking his head.

"Did you and your steward bring your revolvers with you?" asked Ennerling.

"No; we tossed them into the sea as we dived," laughed Mr. Lawton.

"Bringing weapons to a Naval craft is like carrying coals to Newcastle."

"Unfortunately," rejoined the commander, plaintively, "this isn't yet a Naval vessel, and the most dangerous weapon aboard is the breadknife in the galley. But how did the mutiny start, Mr. Lawton? And how did you come to have such a rascally crew aboard?"

"Two or three bad men got into the crew, started fights, and some of the old crew quit. Then these bad men pa.s.sed the word to other tough characters to apply to my captain. In a short time the crew was all of one piece of cloth, including the fellows in the engine room."

"How many mutineers are there aboard?"

"Thirteen, in all. Even the cook joined them."

"But your officers?"

"Captain Peters and Mate Sidney. It was the mate's watch when the trouble started. You see, as most of my cruises have been short, I carried but one mate. So, on a long run, the captain had to stand watch in turn. Captain Peters was below. Mate Sidney went forward, to the forecastle, for something. He must have been felled and ironed. One of the crew roused the captain, saying the mate needed him forward.

Then Captain Peters went forward, was seized and ironed. Then, howling like fiends, in order to frighten us the more, the mutineers rushed aft."

"Yet you stood them off?"

"Yes; Steward Johnson and I both happened to be on deck, and were both armed. The rascals didn't want any of their side killed, so they tried to parley when they saw our weapons."

"What started the mutiny?"

"Mrs Lawton usually carries her jewels, when on board. They are worth two hundred thousand dollars--a rich prize to desperate thieves."

"What folly to tempt men so on the broad ocean!" muttered Commander Ennerling, under his breath.

"The jewels were kept in a safe in the cabin," continued Mr. Lawton.

"And there are the scoundrels just smashing in the cabin door," broke in Jack Benson.

"There they go, piling below."

"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."

Then, leaning over the manhole, Commander Ennerling shouted down:

"Watch below!"

"Aye, aye, sir!" rose Hal's voice, clear and strong.

"Pa.s.s the word to load the torpedo tube."

"Aye, aye, sir!"

Next, hailing the "Selma," Ennerling called:

"Last hail before trouble! Do you surrender?"

"No, you sea-lawyer!"

Just a word to Jack from the Naval officer, and the "Pollard" shot ahead of the other craft, then came up and around, going after the yacht on the quarter, nose on.

"I hope this line of business works," remarked Ennerling, with a dry smile.

"Toot! toot! too-oo-oot!" sounded the yacht's steam whistle, shrilly.
