CHAPTER XI.

TOM’S PLAN FOR RESCUE.

The words of the old salt were an inspiration to the anxious group in

the steersman’s section of the craft.

“What’s your plan, Tom?” asked Mr. Dancer, bravely banishing all trace

of alarm from his voice.

“Just this. We’ll see if we can’t shoot ourselves loose.”

“Shoot ourselves loose!”

The others looked at Tom Jesson as if he had gone suddenly crazy. But

he returned their glances without a trace of embarrassment.

“I mean just what I said,” he repeated steadily.

In his voice there was a ring that compelled respectful attention to

his next words.

“We have a submarine gun?”

“Yes,” responded Mr. Chadwick eagerly.

“Well, now’s the time to use it.”

“In what way?”

It was Mr. Dancer’s turn to ask questions.

“To cut that rope.”

“Jove! Chadwick, the boy’s right!”

The inventor clapped Tom on the shoulder.

“You take charge of this,” he said; “anyhow, you know the details of

the gun as well as I do by this time.”

“I’m not saying that my plan will be successful, mind,” warned Tom.

“Carry it out on your own lines. I’ll depend upon you absolutely.”

Thanks,” said Tom, half laughing, “but I’ll need help.”

“You shall have it,” agreed the inventor instantly.

“Whom do you wish to aid you?” inquired Mr. Chadwick.

“Silas and Jupe,” was the reply; “Silas knows the gun almost as well as

I do. Jupe can carry ammunition.”

“Silas! Jupe!”

The two summoned by Mr. Dancer appeared. Silas’s weatherbeaten

countenance betrayed no signs of emotion. Jupe, on the other hand,

evidenced every variety of fear.

“Fo’ de lub ob de Holy Poker, Marse Jack!” he cried, “what kin’ ob new

trubbel am dis?”

“Why, you are not scared, Jupe?”

“Not scared? Gorryme! Fust mah soup am spilled, ah’m scal-dead, an’

ebberyting knocked galley west, den ah heahs dat we am stuck at de

bottom ob de sea!”

Jupe threw his hands above his head.

“Lan’s sakes and Moses pipes!” he cried, “what you tink ah am? Annuder

Jonah at de bottom ob de ullibguitous ocean, swallowed up in de tummy

ob a ombliferous whale?”

Even in their predicament they could not help laughing at the old

negro’s perturbation.

“Cheer up and get to work, Jupe, and stop enriching the English

language,” urged Mr. Chadwick.

“Yep, ef he don’t stow that guff I’ll treat him as we did landlubbers

on the old _Ohio_,” growled Silas, with a meaning look at the shaking

Jupe.

“Ah don’t want nuffin’ lak dat; ’deed I don’t, Marse Siltack,” he

wailed; “wha’ you want me to do, sah?”

“I’ll show you, you fountain-pen-colored moke, jes as soon as I get my

sailing orders,” roared Silas.

“That won’t be long,” declared Jack. “Fire away, Tom.”

“I want some ammunition for the submarine gun and then I want you to

help me handle it,” said Tom.

“Bully for you, my hearty!” cried Silas. “I used to was first mate back

on the old _Ohio_—first gunner’s mate, I mean. Ever hear the song:

“‘There was Bill Smith and me!

In our country’s navee;

We served ’em on the sea;

Wet or dry; yo-ho!

And we—— ’”

“That will do, Silas,” broke in Mr. Dancer, “take Jupe and bring that

ammunition at once.”

“Aye, aye, sir!” declared Silas in what he would have called

“man-o’-war fashion.”

“Come on, you black imp of Satan,” he concluded to Jupe; “let’s get

some pills fer that gun.”

“Pills!” cried Jupe. “Fo’ de lan’s sake, Marse Silas, sah! We got stuck

on de bottom ob de sea and you talks ‘bout givin’ de gun medicine!

I resigns mah commission as chief cook and bottle washah ob dis yar

packet jes’ as soon as we gits asho’—ef we ebber do.”

“And if not?” Tom teased him.

“Wa’al, sah, den I ’signs it anyhow.”

A few minutes later Silas and Jupe had brought the ammunition for the

submarine gun from the steel-walled magazine in which it was kept.

Naturally, steam being the driving power for the projectile, there was

no powder necessary. In fact, the explosive bullet used looked much

like the missile hurled from a four-inch, quick-firing gun.

It was highly polished, and at its extremity had a sort of

mushroom-shaped tip. This was the “bow,” so to speak, of this submarine

death craft. It was made broad so that it was not likely to miss

anything at which it was aimed. The idea of the projectile was that

as soon as it struck an object the mushroom-shaped tip drove down on

a mercurial cap, which exploded the charge of high explosive when it

detonated.

The gun was sighted through a small tube with an illuminated “eye” at

its extremity. Through this tube it was possible to see outside the

metal walls of the diving boat, and to sight the object to be aimed at

in the glow cast from the searchlights in the observation tube.

Many times during the weeks of work on the _White Shark_ Tom had

experimented with the gun, and now there was no hesitation in his

manner as he placed an explosive shell within the breech of the gun

and closed it. This done he sighted the weapon carefully and then, with

compressed lips and grim, determined manner he pressed the lever that

admitted the water to the superheated chamber.

A small wheel was then turned which closed the water chamber. When it

had been thus sealed, Tom’s next act was to press the button which set

the electric current to its work of turning the water into superheated

steam.

“One! two!” he counted, and then, with a quick nod as of assurance that

he would succeed, he bent over the gun and suddenly twisted a small

handle.

There was not a sound, but every one standing in the chamber knew that

the gun had been fired. It was almost uncanny, this idea of releasing

a giant force without there being the faintest sound to show that the

projectile had sped on its way through the water.

Following the discharge of the gun came a moment of intense anxiety,

and then a cry from the inventor:

“Hurray! It’s succeeded!”

“Good shot, my boy!” cried Mr. Chadwick.

Peering through the observation tube, they had seen the snake-like line

of the rope part as the projectile struck it and exploded, turning the

water all about into thick white obscurity. This condition lasted only

an instant after the explosion. It then became clear that the _White

Shark_ was once more free.

Jack and Tom scampered to the engine room as soon as they saw that the

dangling rope no longer menaced the safety of the ship.

“Rise at full speed!” came the shouted order from Mr. Dancer.

The motors whirred and the _White Shark_ shot toward the surface.

It was not till then that Jack said in a speculative voice:

“Shouldn’t wonder if there’ll be trouble when that ship up above finds

out we’ve cut her anchor line.”
