It registered one hour and a half since we had stepped through the icy portal of King Gelidus’ domain. Allowing a half-hour for the time I lay unconscious, it showed that our mad descent on the back of the crystal monster had lasted quite a full hour, and reckoning the average speed of the escaping mass of ice to have been a mile and a half a minute, that we were now in the neighborhood of ninety miles away from the cold kingdom where Gelidus sat on his icy throne, and Princess Schneeboule at his feet with Chillychops beside her.

It was with great difficulty that I could rise to my feet, so stiffened were my joints and knotted my muscles after that terrible ride, every instant of which I expected to be dashed to pieces against projecting rocks, or torn to shreds by being caught between the fleeing monster of ice and the gigantic icicles hanging from the ceiling like the shining teeth of some huge creature of this under world.

THE TROPICS OF THE UNDER WORLD.

But could it be, dear friends, that Bulger and I had only escaped a quick and merciful ending to be brought face to face with a death ten times more terrible, in that it was to be slow and gradual, denied even the poor boon of looking upon each other, for darkness impenetrable was folded about us and silence so deep that my ears ached in their longing for some sound to break it. And yet there was something in the sound of my own voice that startled me when I used it: it seemed as if the awful stillness were angered at being disturbed by it, and smote it back into my teeth.

Where are we? This was the question I put to myself, and then in my mind I strove to recall every word which I had read in the musty pages of Don Fum’s manuscript concerning the World within a World; but I could recollect nothing to enlighten me, not a word to give me hope or cheer, and I was about to cry out in utter despair when, happening to raise my eyes and look off in the distance, I saw what seemed to me to be a jack-a-lantern dancing along on the ground.

It was a strange and fantastic sight in this region of inky darkness, and for a moment I stood watching it with bated breath and wide-opened eyes; but no, it could not be a will-with-the-wisp, for now the faint and uncertain glimmer had increased to a mild but steady glow, reaching away off in the distance like a long line of dying camp-fires seen through an enveloping mist.

But in a moment’s time this wide encircling ring of light had so increased in brightness that it looked for all the world like a break o’ day in the land o’ sunshine, and here and there where its mild effulgence overcame the darkness of this subterranean region, I caught sight of walls and arches and columns of snow-white marble. And then as I called to mind Don Fum’s mysterious reference to “sunrise in the lower world,” I swung my hat and gave a loud cry of joy, while Bulger waked the echoes of these spacious caverns by his barking. I tell you, dear friends, not until you have been in just such a plight can you know just how such a rescue feels.

And now, no doubt, you are a bit anxious to know what sort of a sunrise could possibly take place in this under world miles below our own.

Well, when you have travelled as many miles as I have, and seen as many wonders as I have, you’ll be ready to admit that wonders are quite as commonplace as commonplace itself. Know, then, that this vast region of the World within a World was girt round about by a broad and placid stream whose waters swarmed with vast numbers of gigantic radiate animals, such as polyps, sea-urchins, Portuguese men-of-war, sea-anemones, and the like; that these transparent creatures, which had the power of emitting light, after lying dormant for twelve hours, gradually unfolded their bodies and tentacles, and rose toward the surface of these calm and limpid waters, increasing by degrees their mysterious radiance, until they had chased the darkness from the vast caverns opening upon the banks of the river, and lighted up this under world with a soft effulgence somewhat brighter than the rays of our full moon. For twelve hours these weird lanterns of the stream made it day for this nether world, and then, as they gradually shrank together and sank out of sight, their expiring fires glowed with all the multicolored radiance of our fairest twilight, and the night, blacker than Stygian darkness, came back again. But now ’twas full daylight, and bidding Bulger follow me I walked in silent wonder along the banks of this glowing stream, which, like a band of mysterious fire, as far as my eye could reach went circling around the white marble mouths of these vast underground chambers.
