The Sea Lion was a United States submarine, yet she was not
constructed along the usual naval lines. It was said of her that she
looked more like a pleasure yacht built for under-surface work than
anything else.
It is not the purpose of the writer to enter into a minute description
of the craft. She was provided with a gasoline engine and an electric
motor. She was not very roomy, but her appointments were very handsome
and costly.
There were machines for manufacturing pure air, as is common with all
submarines of her class, and the apparatus for the production of
electricity was modern and efficient. Every compartment could be
closed against every other chamber in case of damage to the shell.
The pumps designed to expel the water taken into the hold for the
purpose of bringing the craft to the bottom were powerful, so that she
seemed to sink and rise as easily as does a bird on the wing. At top
speed she would make about twenty miles an hour.
On a trial trip taken by Ned on the day before the visit of Captain
Moore to the Black Bear clubroom, the double doors and closet which
enabled one to leave or enter the boat while under water had been
thoroughly tested and found to work perfectly.
The diving suits--which had been manufactured to fit Ned and Frank,
Jack and Jimmie--were also found to be in perfect condition.
On the whole, the Sea Lion and her appurtenances were in as perfect
condition as science and experience could make them on the day the
four boys, accompanied by a naval officer, left the train at Oakland
and proceeded to the navy yard up the bay.
By the middle of the afternoon the boys were on board, receiving their
final instructions from Lieutenant Scott, who had arranged for the
transportation of the Sea Lion from New York and attended to all other
details connected with the trip.
After a long talk regarding the perils to be encountered, Lieutenant
Scott drew forth a map of peculiar appearance and laid it on the table
in the chamber which was to serve as a general living room.
"I have retained possession of this map until the last moment," the
officer said, "because it is most important that no eyes but those of
the occupants of the Sea Lion should rest upon it. It shows where the
lost vessel went down, shows the drift there, the depths, and various
other details of great moment.
"The Cutaria, as you doubtless know, went down off the Taya Islands, a
small group to the east of the large island of Hainan, which, in turn,
is off the coast of China, being separated, if that is a good word to
use in this connection, from the eastern coast by the Gulf of Tong
King.
"Immediately following the sinking of the ship divers were sent down.
They found the lost ship resting easily in about sixty feet of water.
A few days later, however, when other divers went down, the wreck was
not at the place described by the first operators.
"There are drift currents there, but it is remarkable that so heavy a
wreck should have been shifted so suddenly. There are no indications
that the vessel has been buried in the sands of the bottom. Your duty
is to search the ocean floor then and locate the wreck. Having done
this you are to secure the treasure, if possible. In case you cannot
do this, you are to steam to Hongkong and report what assistance you
require.
"And remember this: You are not to destroy or mislay any documents you
may find in the gold room. You are not to reveal the purpose of your
mission at any port you may touch on the way out, or at any port you
may visit for the purpose of reporting progress.
"If at any time you have reason to believe that another submarine is
working or loitering about in the vicinity of the wreck, you are to
report the fact without delay and a man-of-war will be sent to you."
"I knew it!" shouted Jimmie. "I just knew we were in for somethin' of
the kind! There'll be doin's."
"I reckon we can take care of the Diver," said Frank, "and Mr. Arthur
Moore, son of Captain Henry Moore, with it."
"Don't underestimate the Diver," warned Lieutenant Scott. "She is a
peach of a submarine, and Mr. Arthur Moore knows how to operate her.
She is almost the latest thing in submarines."
"Why didn't the Government buy her, then?" demanded Jack.
"Principally because she was withdrawn from the market," was the
reply.
"But how did they get the Diver here so quickly?" asked Ned.
"The same way I got the Sea Lion here," was the Lieutenant's reply.
"They engaged a special train, took the boat to pieces as far as
practicable and sent her over."
"But she is something of a whale as compared with the little Sea
Lion," urged Ned. "It was easy enough to get our boat across the
continent."
"Not quite so easy as you think," laughed the officer. "Still," he
added, "here she is, all ready for the trip. There are plenty of
provisions, and everything is in fine working order. You, Mr. Nestor,
took a hand in taking the submarine to pieces, and you ought to know
all about her."
"I think I do," was the reply, "still, I should have liked the chance
of putting her together again."
"It is all right as it is," was the reply. "You doubtless had a good
time in New York while the work was being done here. When I left for
the big city to ride over with you she was nearly ready, and now, on
our arrival, she is, as you see, right and fit."
"But I thought we were to cross the Pacific in a steamer and pick up
the Sea Lion over there," Ned observed.
"Right you are," the Lieutenant answered, "but the Sea Lion is to be
taken over by the big steamer, too."
"Then they've got to take her to pieces again," wailed Jimmie, "and it
will be weeks before we get started."
"You are wrong there," the officer replied. "The Sea Lion will be
picked up by something like a floating dock and towed over. How does
that strike you?"
"And this floating dry dock," continued the officer, "will be roofed
over and its contents kept secret. A short distance from the Taya
Islands, she will be shucked of her shell and take to the water. No
one will know what her mission is."
"It seems to me that everything is pretty cleverly planned," Ned
remarked. "I hope all my plans will come together as nicely as the
plans of the Government have."
"That will be a big tow for a steamer," Jimmie suggested.
"Yes, it is awkward, but there seemed to be no other way. The Diver
will be far in the rear and you take water off the Taya Islands."
"And on the way over," Ned said, "I can live in the Sea Lion and
continue my studies of the machinery."
From outside, seemingly from underneath the keel of the Sea Lion, came
a grating sound, which was followed by a slight, though steady,
lifting of the vessel.
"Gee!" cried Jimmie, springing to his feet. "I guess we're up against
an earthquake!"
The boys were all moving about now, but Lieutenant Scott remained in
his chair, a smile on his face.
The Sea Lion rose steadily, and there was a slight tip to port. Ned
sat down with a shamed look on his face.
"Say," Jack exclaimed, "was the submarine put together on the float
that is going to carry her across?"
"Of course she was," laughed the Lieutenant. "The pieces brought on
from New York were assembled on the float. Some of the larger pieces,
the ones most difficult to handle, were made here from patterns sent
on from the east. Then, when all was ready, the float was dropped out
of sight so the submarine would lie on the surface, as we found her."
"And now they're lifting the float?" asked Jimmie.
"Exactly," was the reply. "Suppose you go outside, on the conning
tower, and look about."
"You bet," cried Jack, and then there was a rush for the stairway, or
half-ladder, rather, leading to the tower.
The Sea Lion was still lifting, though where the power came from no
one could determine. While Ned studied over the problem Lieutenant
Scott laid a hand on his shoulder.
"You want to know what makes the wheels go round?" laughed the
officer. "Well, I'll tell you. The bottom of the float forms a tank.
Now do you see?"
"And there's a large hose laid from the tank to the shore, and the
water is being pumped out! I see."
"That's it," replied the Lieutenant. "Now that we are getting up high
and dry, you boys can step down on the floor of the float and look
about. I don't think there was ever a contrivance exactly like this.
Go and look it over."
Night was falling, and a chill October wind was blowing in from the
Pacific. There were banks of clouds, too, and all signs portended
rain. It would be a dismal night.
Leaving Lieutenant Scott in the conning tower, the boys all clambered
down to the floor of the float to examine the blockings which kept the
submarine on a level keel. They were gone only a short time, but when
they climbed up the rope ladder to the conning tower again the light
was dim, and a slow, cold rain was falling. The Lieutenant was not on
the conning tower, and Ned at once descended to the general living
room of the submarine. Before he reached the middle of the stairs the
lights, which had been burning brightly a moment before, suddenly went
out, and the interior of the submarine yawned under his feet like a
deep, impenetrable pit.
Fearful that something was amiss, Ned dropped down and reached for his
electric searchlight, which he had left on a shelf not far from the
stairs. Something passed him in the darkness and he called out to the
Lieutenant, but there was no answer. Then, out of the darkness above,
came a mingled chorus of anger and alarm.
