CHAPTER XIX

A MARVELOUS BOAT

So many new and strange sensations had crowded on the motor boys

in the last few days that it hardly needed the additional one of

traveling in a submarine to thrill them. Nevertheless the three lads

did feel strange as they stood there in the half-darkened cabin, and

looked at the greenish water slipping past the thick plate-glass side

windows--windows illuminated in such a way that the very life of the

sea was visible.

“Look--look!” exclaimed Bob, in a low voice. “See that shark!”

And indeed, at that moment, a great sand shark that was keeping pace

with the marvelous boat looked in through the glass window, as if to

ask what manner of sea companion he had fallen in with.

“Oh--oh!” cried Grace, as she clutched her father’s arm. “Suppose that

window should break!”

“I don’t want to suppose anything like that,” spoke Jerry solemnly.

“It’s too--too unpleasant. Oh, but this is wonderful--wonderful!”

“It’s the greatest thing ever!” declared Ned with conviction. “I never

dreamed we should ever see anything like this. Oh, there’s another

shark--a hammer-head,” and the hideous creature, with its bulging eyes

on projections that give it the name, resembling a double-ended hammer,

swam up, also to peer in at the windows.

“Wonderful--wonderful,” murmured Professor Snodgrass. “This will just

suit my purpose. I must have a talk with Dr. Klauss, and arrange to

have him take us on a long trip. I will not only be able to get my

hermit crabs, but I can make many other valuable discoveries. Science

will be greatly the gainer by our accidental finding of this submarine.

Yes, I hope this trip will be a long one.”

“You are not likely to be disappointed in that, sir,” observed Mr.

Sheldon, and there was in his tone such a peculiar meaning that Bob

asked:

“Why do you say that, Uncle Nelson?”

“Because it’s true. This man--hush, here he comes now. I can’t tell you

any more at present. We must have a talk together, presently.”

The sound of someone coming along a steel-floored passage warned them

to talk in low tones.

“But what does it all mean?” asked Jerry, in bewilderment.

“Oh, we don’t know--we can hardly guess,” spoke Grace in his ear. “Papa

will tell you. I can only say that this Dr. Klauss, in spite of his

seeming politeness, is a terrible man. I’m so glad you boys are with

us. Perhaps now we can escape!”

“Escape!” gasped Jerry. “Why--why----”

“Hush! Here he is!” warned Grace.

It was not Dr. Klauss, however, but one of his men with a supply of dry

clothing for the boys and the professor.

“I will take you to the cabins you are to occupy,” said this man, who

spoke without any German accent. Jerry was glad to note this. It meant,

in case of trouble, that perhaps they could count on this American to

aid them. Jerry was sorely puzzled.

“You are to come with me,” the man went on, respectfully. “After you

are dressed I will take your clothing to the engine room to dry. Then

you will be served with a meal, Dr. Klauss says. Come.”

“Supper, eh?” cried Bob. “That sounds good, anyhow.”

“I see you haven’t gotten over your old habit,” laughed Mr. Sheldon.

“Well, come back when you can, boys. We are certainly glad to see you.”

“Yes, indeed,” echoed Grace, and she looked at Jerry particularly. He

understood what she meant.

“And to think that we are actually traveling under water!” marveled

Ned. “About how deep are we?” he asked of the man who had brought the

clothing.

“Oh, about three hundred feet, I should judge. I didn’t notice the gage

as I came through the engine room. But Dr. Klauss will probably let you

see for yourselves soon.”

“Are we still going down?” asked Jerry.

“A little, yes. About five hundred feet is as deep as we can go, for,

even in this wonderful boat, which is the best submarine I ever saw or

heard of, the weight of water much below five hundred feet would crush

us like an egg shell. In fact there are very few boats of this class

that go more than two hundred feet down, and really that depth isn’t

necessary even in war time. But we members of the crew are not supposed

to give out information. Dr. Klauss would not like it. So you’ll have

to excuse me.”

“That’s all right,” said Jerry. The man seemed a pleasant chap, and

spoke like a person of intelligence. Jerry was glad he was aboard, for

somehow, the tall lad felt an indefinable sense of danger.

The boys were taken to small adjoining staterooms, where they were

told to change, and put their wet garments outside. The clothing that

had been supplied to them was all sorts of odds and ends, evidently

collected from different members of the crew. But it was dry and warm,

and a welcome relief from their drenched garments, the wearing of which

much longer would have given them all colds.

“This is some change from out in that storm, on the back of this

submarine, knocking to be let in; isn’t it, fellows?” called Jerry from

his stateroom.

“I should say yes,” agreed Ned. “Poor old _Comet_! What do you suppose

happened to her?”

“I’m afraid she’s broken up,” answered Jerry, mournfully. “Once the

pontoons give way, the weight of the engines will sink her. Well, we

can build another.”

“Or a submarine,” added Ned.

“First we’ve got to see if we can get off of this one,” said Jerry in a

low voice.

“What do you mean?” asked Ned, who had dressed quickly, and now stood

at the door of his chum’s stateroom.

“You’ll see soon enough,” was the answer. “There’s something strange

going on here, boys. Grace and Mr. Sheldon could only give a hint of

it. We’ll have to be on the watch. This man Klauss----”

“Cheese it!” interrupted Ned, effectively if not elegantly. “He’s

coming!”

Jerry halted his remarks just in time, for the inventor of the

submarine came along a second later.

“Well, boys,” he asked, in a tone he tried to make cordial, “how are

you making out? Will those clothes answer until your own are dry?”

“Very well indeed, yes; thank you,” replied Jerry. “We are sorry to

have to put you to so much trouble----”

“It could not be helped,” was the response of the German. “I could not

leave you there to drown. Now if you will come with me I will tell you

something about my ship--it is my one hobby!”

“And you will not forget about giving me a chance to get to the

bottom of the sea, and capture some crabs; will you?” asked Professor

Snodgrass.

“I will do what I can for you--as a fellow scientist,” said Dr. Klauss.

The boys found Grace and her father eagerly awaiting them, and a hasty

midnight meal was served in the main cabin. Dr. Klauss left the little

party to themselves, saying that he had to go to see about some of the

mechanism.

“Say, I don’t see what we’ve got to complain of,” remarked Bob, with

his mouth half full. “Here we are, warm and dry, even if we are under

water, and we’ve got plenty to eat----”

“Which, I suppose, excuses many evils in your eyes, Bob, my boy,”

interrupted his uncle. “Oh, Dr. Klauss will not starve us--of that

Grace and I have had excellent proof.”

“Well, then we’ll be all right,” spoke Chunky, with a contented sigh,

as he helped himself to some more cake, for the menu included even

that. “They have a good cook here,” went on the stout lad.

“We must find time and the chance for a consultation,” remarked Mr.

Sheldon, speaking rapidly, and in a low voice. “I want to explain

certain things, and plan what to do.”

“Is there any danger?” asked Jerry.

“Yes--I think so--of a certain kind--though I do not mean that our

lives are actually at stake. But our liberty certainly is.”

“You mean----” began Ned.

“I mean that this fanatic refuses to set Grace and me ashore, or to

let us go aboard some other vessel. I want you boys to make that same

request, when the time comes, and see what he says. Then we will have

something to go on. But be very careful. Oh, it is good to be with

friends again!” and Mr. Sheldon looked affectionately at the lads.

Dr. Klauss came in before the meal was finished. All this time the

_Sonderbaar_ was plowing along beneath the surface, but at what

depth, or in what direction the boys could only guess. There were no

indicators in this main cabin.

“Would you lads like to see something of my submarine?” asked the

German.

“Indeed we would!” exclaimed Jerry with an enthusiasm that was echoed

by his chums.

“Then come with me,” invited their strange host, and he led the way

toward the engine room, as could be told by the hum and throb that came

from it. “Will you accompany us, Mr. Sheldon?”

“Thank you, no. I will stay with my daughter. It is late, and she ought

to retire.”

Indeed it was long past midnight, but in that depth of water time did

not seem to count for much. There was perpetual darkness at all hours.

But the boys and Professor Snodgrass, though tired after what they

had passed through, were not too weary to view the interior of this

marvelous boat.

I do not wish to tire my readers with a technical description of the

_Sonderbaar_, so I will merely say that she was, like most submarines,

of elliptical shape, tapering to blunt points on either end, though the

stern, where the two propellers were, was wider than the bow.

The boat was about two hundred feet long and about forty feet in

diameter, her dimensions being greatly in excess of most submarines.

It was this that enabled her to be made strong enough to stand the

pressure of five hundred feet of water, which pressure is enormous on

every square inch of surface.

This large size also gave more room inside for engines, and quarters

for captain and crew. Thus there was much more comfort than in the

usual submarine.

There were no periscopes, or tubes, elevated above the deck on the

_Sonderbaar_. Observation, when running awash, was by means of a lens

flush in the deck, a peculiar arrangement of mirrors and prisms giving

the effect of periscopes without their disadvantages.

There was also an automatic arrangement of diaphragms, similar to those

in telephone receivers, so that when the craft was running under water,

and approached some obstacle, its presence would be made manifest in

time to avoid it. Nor was this all. Dr. Klauss had perfected a powerful

lamp which was located in the bow of his craft, projecting its beams

through the water. This would also disclose any object that might

endanger a collision. But the diaphragms acted over a wider area than

the lamp, the beams of which were necessarily dimmed by the density of

the water.

As in all submarines, it was necessary to let water into ballast tanks

in order to make her sink, and to rise it was only necessary to pump

out this same water, by means of compressed air. But Dr. Klauss had

made many improvements even in this simple and fundamental principle.

The propulsion of the _Sonderbaar_ was by means of twin screws at the

stern, and each screw had its own engine--a gasoline one when running

on the surface, and an electrical motor, run by a new type of storage

battery, when submerged. The propeller shafts passed through the

armatures of the motors, which were mounted directly on the shafts,

revolving with them, and acting as flywheels when the gasoline engines

were being used. At such times the circuits of the field windings were

open, and no current was generated.

There were also dynamos for the making of electric illumination and

charging the storage battery, and small motors to work pumps and other

devices. In fact the craft was complete, mechanically.

She was steered by two rudders, one to guide her to port or

starboard--or left and right, as the new navy regulations specify--and

another rudder to send her to the surface or toward the bottom of the

sea.

All this Dr. Klauss showed the boys, explaining many things, for he saw

they were greatly interested; but, of course, there were some secrets

he did not reveal. And one of these was the method of firing the

deadly torpedoes.

The ship could be controlled from the engine room, or from the pilot

house, in the bow, and here there was a perfect maze of levers, wheels,

switches and other devices. Gages told of the boat’s speed, of her

depth, and gave all the information it was necessary for the pilot to

know.

“And now I think you need rest,” said the inventor, when the tour of

the boat was completed. “I shall see you in the morning.”

“You have a marvelous boat, Dr. Klauss,” said Jerry, sincerely. “I

congratulate you.”

“Thank you, my lad. I am sorry we had to leave your own air craft at

the mercy of the sea, for, from what Mr. Sheldon told me of her, in our

conversations after I rescued him, I understand it was a wonder of its

own kind. But I had my own reasons for not lingering longer there.”

“Oh, well, it couldn’t be helped,” said Jerry, but he could not refrain

from sighing.

“Say, I don’t see what’s the matter with Dr. Klauss. He seems very

decent,” remarked Bob, when the boys had reached their staterooms.

“Better wait,” remarked Jerry, significantly. “Mr. Sheldon didn’t make

his remark for nothing.”
