Chapter 7: We Discover the Interior World

The officers and sailors responded to my speech with ringing cheers. Every man of them volunteered to stay by the ship and continue our voyage down the gulf. Whatever malcontents there may have been among the sailors, those, influenced by the prevailing enthusiasm, were afraid to exhibit any cowardice, and all were unanimous for further exploration.

I signalled our resolution by a discharge of three guns, which created the most thrilling reverberations in the mysterious abyss.

Starting the engine again, the prow of the Polar King was pointed directly toward the darkness before us, toward the centre of the earth. We were determined to explore the hollow ocean to its further confines, if our provisions held out until such a work would be accomplished.

We hoped at midnight to obtain our last look at the sun, as we would then be brought into the position of the opposite side of the watery crater down which we sailed. At eleven o’clock the sun rose above the limb of the gulf, which was now veiled in darkness. We were gladdened with two hours of sunlight, the sun promptly setting at 1 A.M. of the new day.

We continued our voyage in the semi-darkness, the prow of the vessel still pointed to the centre of the earth, while the polar star shone in the outer heavens on the horizon directly over the rail of the vessel’s stern.

It did not appear to us that we were dropping straight down into the interior of the earth; on the contrary, we always seemed to float on a horizontal sea, and the earth seemed to turn up toward us and the polar cavern to gradually engulf us. The sight we beheld that day was inexpressibly magnificent. Five hundred miles above us rose the crest of the circular polar sea. Its upper hemisphere glowed with the light of the unseen sun. We were surrounded by fifteen hundred miles of perpendicular ocean, crowned with a diadem of icebergs!

Glorious as was the sight, the sailors were terribly apprehensive of nameless disasters in such monstrous surroundings. It was impossible for them to understand how the ocean roof could remain suspended above us like the vault of heaven. The idea of being able to sail down a tubular ocean, the antechamber of some infernal world, was incomprehensible. We were traversing sea-built corridors, whose oscillating floors and roof remained providentially apart to permit us to explore the mystery beyond.

Mid-day on the 13th of May brought no sight of the sun, but only a deepening twilight, the dim reflection of the bright sky we had left behind. The further we sailed into the gulf the less its diameter grew. When we had penetrated the vast aperture some two hundred and fifty miles, we found the aërial diameter was reduced to about fifty miles, thus forming a conical abyss. We were clearly sailing down a gigantic vortex or gulf of water, and we began to feel a diminishing gravity the further we approached the central abyss.

The cavernous sea was subject to enormous undulations, or tidal waves, either the result of storms in the interior of the earth or mighty adjustments of gravity between the interior and exterior oceans. As we were lifted up upon the crest of an immense tidal wave several of the sailors, as well as the lookout, declared they had seen a flash of light, in the direction of the centre of the earth!

We were all terribly excited at the news, and as the ship was lifted on the crest of the next wave, we saw clearly an orb of flame that lighted up the circling undulations of water with the flush of dawn! We were now between two spectral lights--the faint twilight of the outer sun and the intermittent dawn of some strange source of light in the interior of the earth.

The sailors crowded to the top of both masts and stood upon cross-trees and rigging, wildly anxious to discover the meaning of the strange light and whatever the view from the next crest of waters would reveal.
