Part 32 (1/2)

”Then we will make the attempt,” the professor added. ”Now all aboard for the place where the water shoots up!”

Questioning Hankos, the professor learned how to reach the strange place. It was in the midst of a desolate country where none of the giants ever went, so afraid were they of the strange phenomenon.

It was a week's journey. Sometimes the Mermaid flew through the air, and again it sailed on vast lakes or inland seas. On the trip they met with big waterfalls and terrible geysers that spouted a mile or more into the air. They traveled by night as well as day, though it was necessary to keep a sharp watch.

Sometimes the s.h.i.+p pa.s.sed through great flocks of birds that surrounded her and sought to pierce the aluminum hull with their sharp beaks and talons. Over the mountains and valleys the s.h.i.+p sailed until, one evening, there sounded through the air a strange rumbling sound.

”It is thunder,” said Old Andy.

”It is the water column,” replied the scientist. ”We are at the end of our trip. May the remainder be as successful!”

The s.h.i.+p was lowered to the surface, as it was deemed best to approach the column when the lights were s.h.i.+ning. No one slept much that night, for the roaring and rumbling never ceased.

In the morning the s.h.i.+p was sent forward slowly. Ever and ever the terrific sound increased, until it was almost deafening. They had to call to each other to be heard.

Then, as the Mermaid pa.s.sed over a mountain, the adventurers saw, in a valley below them, the up-shooting water.

It was a vast column, nearly three hundred feet in thickness, and as solid and white as a shaft of marble. Up, up, up, it went, until it was lost to sight, but there were no falling drops, and not even a spray came from the watery shafts.

”There is a terrible power to it,” the professor said. ”May it prove our salvation!”

The s.h.i.+p was lowered about a hundred feet away from the waterspout.

All around them the ground was vibrating with the force of the fluid.

”To think that connects with the world above!” exclaimed Jack.

”It's a good thing for us that it does,” Mark answered.

”We must lose no time,” the professor put in. ”If the earthquake destroyed the downward shaft, it may effect this one in time. We must escape while we can.”

Then, for the first time, he opened the storeroom and the big cylinder was disclosed to view. It was made of aluminum, and shaped like an immense cigar. The hull was double, and it was strongly braced. Inside were padded berths for the occupants, and there was just room enough for the seven adventurers. Once they had entered they could not move about, but must stay in their little compartment.

Compressed air in strong cylinders furnished a means of breathing, and there were tiny electric lights operated by a storage battery. There was also a chamber to be filled with the lifting gas. The cylinder was so arranged that it would float on it's long axis if thrown into the water. A trap door hermetically sealed gave access to the interior. A small propeller, worked by compressed air, furnished motive power.

The food supply consisted of compressed capsules on which a man could subsist for several days. There was also some water, but not much, since that can not be compressed and would, therefore, take considerable room.

”The only thing for us to do,” said the professor, ”is to get into the cylinder, seal it up, and trust to Providence. This is what I intended to use when we were caught in the draught.”

”How can we get into the column of water after we shut ourselves into the cylinder?” asked Mark.

”The cylinder fits into a sort of improvised cannon,” said Mr.

Henderson. ”It is fired by electricity and compressed air. We will aim it at the column, press the b.u.t.ton and be projected into the midst of the water. Then----” He did not finish the sentence, but the others knew what he meant.

”When are we to start?” asked Mark.

”As soon as possible,” replied the professor. ”I must arrange the cylinder, compress the air and lay out the food supply.”

It took the rest of the day to do this, as the inventor found it would be advisable to attach a weight to the end of the cylinder, to hold it upright in the column of water. The weight could be detached automatically when they were shot up into the midst of the ocean, where, as Hankos had told them, the column spurted forth.
