Under the Ocean to the South Pole Part 2

At last all was in readiness. The two machinists knocked away the last of the retaining blocks and eased the s.h.i.+p slightly down the well-greased timbers of the ways.

"There she goes!" cried the professor. "Break the bottle, Was.h.i.+ngton!"

"In de name ob de Stars an' Stripes, in de name of liberty, de home of the free an' de land ob de brave, I names yo' _Mrs. Porpoise_!" cried the colored man, but he was so long getting the words out, and so slow in swinging the bottle of soda, that the s.h.i.+p was quite beyond his reach when he had finished his oration. He was not to be outdone, however, and, with a quick movement he hurled the bottle at the moving s.h.i.+p. It struck the blunt nose squarely, and s.h.i.+vered to pieces.

"Three cheers for de south pole!" yelled Was.h.i.+ngton, and the others joined in.

The next instant the _Porpoise_ was riding the waves of the little bay, dancing about as lightly as a cork, though, from the nature of her construction, she was quite low in the water, only about three feet of freeboard showing where the platform was located.

"Well, she floats, anyhow," remarked the professor. "Row out and fasten cables fore and aft," he went on, turning to the two machinists. In a few minutes the _Porpoise_ was fastened to a small dock with strong ropes the two young men had carried out to her in rowboats.

"We will go aboard in a little while," the professor said. "I am anxious to see if she rides on an even keel and how the sinking tanks work."

Aided by the boys, he and Was.h.i.+ngton carried on board a number of tools and appliances. Then, with the two machinists, they all descended into the interior of the craft through the small manhole in the middle of the deck or platform.

Inside the _Porpoise_, the greater part of which was below the surface of the waves and consequently in darkness, the professor switched on the electric lights and then he proceeded to get up steam.

The propelling power of the craft has already been described. In order to make the s.h.i.+p sink beneath the water all that was necessary was to incline the rudder and open certain valves in the four tanks, when the water, rus.h.i.+ng in, would sink her. There was a tank on either side, and one each fore and aft. If it was desired to sink straight down all four tanks were filled at once. If the professor wanted to descend slanting either to the front or back, only one of the end tanks was filled, according to the direction desired. The deflecting rudder also aided greatly in this movement.

To cause the s.h.i.+p to rise the tanks were emptied of the water by means of powerful pumps. The filling of the tanks, as well as the emptying of them, the starting or stopping of the engine that moved the boat, as well as the control of most of the important machinery on the craft could be accomplished from the conning or steering tower, as well as from the engine-room.

There were numerous gages to tell the depth to which the s.h.i.+p had sunk, the steam pressure, density of the water, and other necessary details.

There were dynamos to make light, motors to run the pumps, and a great storage battery, so that in case of a breakdown to the turbine engine the craft could be run entirely by electricity for a time.

The cooking was all done by this useful current, and all that was necessary to make a cup of coffee or fry a beefsteak was to turn a small switch of the electric stove.

The professor was busy over the machine for generating gas, that furnished the heat to create steam. Soon a hissing told that it was working. In a few minutes the hum and throb of the engine told that it was ready to start.

"We are only going down a little way," the professor said, "and only going to travel a short distance under water for the first time. I think there is no danger, but if any of you want to back out, now is your chance."

No one seemed inclined to withdraw, though Mark said afterward he thought Was.h.i.+ngton got as pale as it is possible for a colored man to get.

"We will all put on life preservers," the inventor went on, "and one of you will be stationed near the emergency exit. In case anything goes wrong, and I cannot make the s.h.i.+p rise, by pulling the lever the top of the craft will be forced off, and, we can at least save our lives. I think we are all ready now. Mark, you clamp down the manhole cover, and Jack, after you close the conning tower station yourself at the emergency lever after we have donned the life preservers."

The cork jackets were adjusted and Mark clamped the manhole cover on.

The professor took one last look at the various levers and handles, and then turned the wheel that admitted water to all four tanks. There was a hissing sound as the sea water rushed in, and the _Porpoise_ gave a sudden lurch.

Then they could all feel the submarine sinking. Down and down she went.

Would she ever stop? Would the professor be able to raise her again?

There were questions that troubled everyone.

Down and down the craft sunk, until by the gage it was indicated that she was twenty feet below the surface. Then the professor shut off the inrush of water and the _Porpoise_ floated away below the surface of the waves.

There was a clicking sound and all the lights went out. The boys and Was.h.i.+ngton gave a gasp of terror. What did the sudden blackness mean.

"Open the side windows," called the professor's voice, and the two machinists obeyed. Heavy steel doors that covered plate gla.s.s windows in either side of the craft were pulled back, and a cry of astonishment broke from the boys.

They looked out and saw staring in at them, so close it seemed that they could touch them, scores of fishes that looked in through the gla.s.s bull's-eyes.

For the first time they realized that they were in the depths of the ocean.

CHAPTER III

RUNNING DOWN A WARs.h.i.+P

"How do you like it?" asked the professor.

"Great!" exclaimed Jack.

"Fine!" cried Mark.

"It am simply coslostrousness!" exploded Was.h.i.+ngton. "'Nebber in all my born days did I eber expansionate on such a sight!"

"Wish I had a fis.h.i.+ng pole and line," remarked Andy Sudds. "There's some pretty nice specimens out there."

"You'll see better ones than those before we finish our trip to the pole," remarked the professor. "Now we will try moving forward. I am going into the conning tower."

He turned on the lights once more, but the boys begged him to shut them off, as they could see out into the ocean when the interior of the s.h.i.+p was in darkness. So the professor obliged them.

In the tower he switched on the powerful searchlight that illuminated the path in front of him. Then he started the engine, slowly at first, and gradually increasing the speed. The _Porpoise_ forged ahead, riding as evenly as an ordinary s.h.i.+p does on the surface.

The professor steered her about in a large circle, bringing her back to the starting point. She worked as smoothly as if she had been used to under-water service for years.

"Now," said the inventor, "we will see if we can go up to the surface again," and there came a little note of anxiety into his voice. He slowed down the engine and started the powerful pumps that were to empty the tanks. For a moment there was a feeling of terror in the hearts of all. Would the pumps work?

Then, slowly but surely, those aboard the _Porpoise_ felt her beginning to rise. Up and up she went as the tanks were emptied and the s.h.i.+p lightened.

Then, with a bounce like a rubber ball, the submarine shot upward to the surface and lay undulating on the waves caused by her emergence from the depths.

"Hurrah!" shouted Jack. "We're all right!"

"We sh.o.r.e am!" exclaimed Was.h.i.+ngton.

"It's a success!" Professor Henderson almost whispered. "The pumps worked. The _Porpoise_ has fulfilled my greatest expectations!"

Then he steered the s.h.i.+p back to the dock, where she was moored, and the adventurers disembarked.

"One or two little details to attend to, and we'll be ready for the great trip," remarked the professor. "I want to give her a little harder trial before I trust her, though she seems to be first-rate."

They all went back to the combined machine shop and cabin, where they had lived during the building of the submarine. Dinner was prepared and, after the meal the two machinists approached the professor.

"I don't suppose you need us any more," remarked Henry Watson. "The s.h.i.+p is finished as far as we can do anything, and we may as well leave now.

We have an offer to go to work in an electrical shop."
