>[45] multiplied the heavy reverberations until the air of the gulf was rent with their thunder. The last explosion was followed by long-drawn echoes of triumph that marked our introduction to the interior world.

Strange to say that on the very threshold of success there are men who suddenly take fright at the new conditions that confront them. It appeared that Boatswain Dunbar and eleven sailors who had unwillingly sailed thus far refused to proceed further with the ship, being terrified at the discovery we had made. I could have obliged them to have remained with us, but their reason being possibly affected, I saw that their presence as malcontents might in time cause a mutiny, or at all events an ever-present, source of trouble. They were wildly anxious to leave the ship and return home; consequently I gave them liberty to depart. The largest boat was lowered, together with a mast and sails. I gave the command to Dunbar, and furnished the boat with ample stores and plenty of clothing. I also gave them one-half of the dogs and two sledges for crossing the ice. When the men were finally seated Dunbar cast off the rope and steered for the outer sea. We gave them a parting salute by firing a gun, and in a short time they were lost in the darkness of the gulf.

CHAPTER VIII. EXTRAORDINARY LOSS OF WEIGHT.

The first thought that occurred to us after the excitement of discovery had somewhat subsided was that the interior of the earth was in all probability a habitable planet, possessing as it did a life-giving luminary of its own, and our one object was to get into the planet as quickly as possible. A continual breeze from the interior ocean of air passed out of the gulf. Its temperature was much higher than that of the sea on which we sailed, and it was only now that we began to think of laying off our Arctic furs.

A closer observation of the interior sun revealed the knowledge that it was a very luminous orb, producing a climate similar to that of the tropics or nearly so. As we entered the[46] interior sphere the sun rose higher and higher above us, until at last he stood vertically above our heads at a height of about 3,500 miles. We saw at once what novel conditions of life might exist under an earth-surrounded sun, casting everywhere perpendicular shadow, and neither rising nor setting, but standing high in heaven, the lord of eternal day. We seemed to sail the bottom of a huge bowl or spherical gulf, surrounded by oceans, continents, islands, and seas.

A peculiar circumstance, first noticed immediately after arriving at the centre of the gulf, was that each of us possessed a sense of physical buoyancy, hitherto unfelt.

Flathootly told me he felt like jumping over the mast in his newly-found vigor of action, and the sailors began a series of antics quite foreign to their late stolid behavior. I felt myself possessed of a very elastic step and a similar desire to jump overboard and leap miles out to sea. I felt that I could easily jump a distance of several miles.

Professor Starbottle explained this phenomenal activity by stating that on the outer surface of the earth a man who weighs one hundred and fifty pounds, would weigh practically nothing on the interior surface of an earth shell of any equal thickness throughout. But the fact that we did weigh something, and that the ship and ocean itself remained on the under surface of the world, proved that the shell of the earth, naturally made thicker at the equator by reason of centrifugal gravity than at the poles, has sufficient equatorial attraction to keep open the polar gulf. Besides this centrifugal gravity confers a certain degree of weight on all objects in the interior sphere.

"I'll get a pair of scales," said Flathootly, "an' see how light I am in weight."

"Don't mind scales," said the professor, "for the weights themselves have lost weight."

"Well, I'm one hundred and seventy-five pounds to a feather," said Flathootly, "an' I'll soon see if the weights are right or not."

"The weights are right enough," said the professor, "and yet they are wrong."

"An' how can a thing be roight and wrang at the same time, I'd loike to know? We'll thry the weights anyway," said the Irishman.

So saying, Flathootly got a little weighing machine on deck,[47] and, standing thereon, a sailor piled on the weights on the opposite side.

He shouted out: "There now, do you see that? I'm wan hundred and siventy-siven pounds, jist what I always was."

"My dear sir," said the professor, "you don't seem to understand this matter; the weights have lost weight equally with yourself, hence they still appear to you as weighing one hundred and seventy-seven pounds."

"Excuse me, sorr," said Flathootly. "If the weights have lost weight, the chap that stole it was cute enough to put it back again before I weighed meself. Don't you see wid yer two eyes I'm still as heavy as iver I was?"

"You will require ocular demonstration that what I say is correct. Here, sir, let me weigh you with this instrument," said the professor.

The instrument referred to was a huge spring-balance with which it was proposed to weigh Flathootly. One end of it was fastened to the mast, and to the hook hanging from the other end the master-at-arms secured himself. The hand on the dial plate moved a certain distance and stopped at seventeen pounds. The expression on the Irishman's face was something awful to behold.

"Does this machine tell the thruth?" he inquired in a tearful voice.

We assured him it was absolutely correct. He only weighed seventeen pounds.

"Oh, howly Mother of Mercy!" yelled Flathootly. "Consumption has me by the back of the neck. I've lost a hundred and sixty pounds in three days. Oh, sir, for the love of heaven, take me back to me mother. I'm kilt entoirely."

It was some time before Flathootly could understand that his lightness of weight was due to the lesser-sized world he was continually arriving upon, together with centrifugal gravity, and that we all suffered from his affliction of being each "less than half a man" as he termed it. The weighing of the weights wherewith he had weighed himself proved conclusively that the depreciation in gravity applied equally to everything around us.

The extreme lightness of our bodies, and the fact that our muscles had been used to move about ten times our then weight, was the cause of our wonderful buoyancy.[48]

The sailors began leaping from the ship to a large rock that rose out of the water about half a mile off. Their agility was marvellous, and Flathootly covered himself with glory in leaping over the ship hundreds of feet in the air and alighting on the same spot on deck again.

Their officers and scientific staff remained on deck as became their dignity, although tempted to try their agility like the sailors.

Flathootly surprised us by leaping on a yardarm and exclaiming: "Gintlemen, I tell ye what it is, I'm no weight at all."

"How do you make that out?" said the professor.

"Well, Oi've been thinking," said he, "that, as you say, we're in the middle of the two wurrlds. Now it stands to sense that the wan wurrld, I mane the sun up there, is pullin' us up an' the t'other wurrld is pullin' us down, an' as both wurrlds is pulling aqually, why av corse we don't amount to no weight at all. How could I turn fifteen summersaults at wance if I was any weight? That shows yer weighing machine is all wrang again."

"How can you stand on the deck if you are no weight?" inquired the professor.

"Why, I'm only pressing me feet on the boards," said the Irishman; "look here!" So saying, he leaped from the yard and revolved in the air at least twenty times before alighting on the deck.

"Now," said the professor, "I'll explain why you only weigh seventeen pounds as indicated by the spring-balance. We have sailed, down the gulf 500 miles, haven't we?"

"Yis, sorr."

"And here we are sailing upside down on the inside roof of the world——"

"Sailin' upside down? Indeed, sorr, an' ye can't make me believe that, for shure I'm shtandin' on me feet like yourself, head uppermost."

"Well, whether you believe it or not, we are sailing upside down, just as ships going to Australia sail upside down as compared with ships sailing the North Atlantic. But the point of gravity is this: Here we are surrounded on all sides by the shell of the earth, which attracts equally in all directions. Hence all objects in the interior world have no weight as regards whatever thickness of the earth's shell surrounds them. You[49] see, weight is caused by an object having the world on one side of it. Thus both the world and the object attract each other according to the density and distance apart. What we call a pound weight is a mass of matter attracted by the earth on its surface with a force equal to the weight of sixteen ounces. A pound weight on the surface of the earth weighs sixteen ounces, and all the mighty volume of our planet, with all its mountains, continents and seas, weighs only sixteen ounces on the surface of a pound weight. The earth may still weigh many millions of tons as regards the sun, but as regards a pound weight it only weighs sixteen ounces."

"That is an illustration of Flathootly's mental calibre," said Captain Wallace. "He only believes what his brain can accommodate in the way of knowledge."

"God bless the captain," said Flathootly, "I'm shure his brain is as big as mine any day in the week."

"Now," continued the astronomer, "it seems to me that the substances of the earth, rocks, metals, and water, have, under the influence of centrifugal gravity, massed themselves very thickly at the equator or point of greatest motion, and stretch toward the poles in a gradually-lessening mass until the polar gulfs are reached. Thus the earth's shell resembles a musk-melon with the inside cleaned out."

"It makes me mouth wather to think of it," said Flathootly.

"Now, listen," said the astronomer; "we are also under the influence of the earth's centrifugal motion, and wherever we are on the interior surface we swing round our circle of latitude in twenty-four hours, and thus men, ship, and ocean are held up against the interior vault like a boy being able to hold water in a vertical position at the bottom of the pail he swings round him at the end of a cord."

"Don't you think, professor," I inquired, "we will become heavier as we approach the region of greatest motion under the equator?"

"I don't think so," he replied, "for the ocean around the poles has naturally gravitated to the internal as well as to the external equator, to restore the equilibrium of gravity. The reason why a man does not weigh less on the external equator than at the poles, although flying around at the rate of a thousand miles an hour, is that the deeper ocean, that is, the extra twenty-six miles that the earth is thicker on the equator, counter balances[50] by its attraction the loss of weight due to the rapid centrifugal motion, and so preserves in all objects on the earth a uniform weight."

"The whole thing," said Flathootly, "is as clear as mud. I'm glad to know, sorr, I haven't lost me entire constitution at all evints, an' if I can only carry home what weight I've got lift I'll make a fortune in a dime museum."

CHAPTER IX. AFLOAT ON THE INTERIOR OCEAN.

As the Polar King sped southward over the interior sea the wonders of the strange world we had discovered began to dawn upon us. The colossal vault rose more and more above us and the sun threw his mild and vertical rays directly upon ship and sea, producing a most delightful climate. The ocean had a temperature of 75 degrees Fahr. and the air 85 degrees. We were absolutely sailing upside down to an inhabitant of the outer sphere, yet we seemed to ourselves to be sailing naturally erect on the sea with the sun above us.

Our first experience in the internal sphere was that of a sudden storm. The sun grew dark and appeared like a disc of sombre gold. The ocean was lashed by a furious hurricane into incredible mountains of water. Every crest of the waves seemed a mass of yellow flame. The internal heavens were rent open with gulfs of sulphur-colored fire, while the thunder reverberated with terrible concussions. The ship would spin upon the water as though every wave were a whirlpool. A golden-yellow phosphorescence covered the ocean. The water boiled
