For several days our work hours were spent in all sorts of experiments, on the degree of salinity in waters of different depths, or on their electric properties, coloration, and transparency, and in every instance Captain Nemo displayed an ingenuity equaled only by his graciousness toward me. Then I saw no more of him for some days and again lived on board in seclusion.

On January 16 the Nautilus seemed to have fallen asleep just a few meters beneath the surface of the water. Its electric equipment had been turned off, and the motionless propeller let it ride with the waves. I assumed that the crew were busy with interior repairs, required by the engine's strenuous mechanical action.

My companions and I then witnessed an unusual sight. The panels in the lounge were open, and since the Nautilus's beacon was off, a hazy darkness reigned in the midst of the waters. Covered with heavy clouds, the stormy sky gave only the faintest light to the ocean's upper strata.

I was observing the state of the sea under these conditions, and even the largest fish were nothing more than ill-defined shadows, when the Nautilus was suddenly transferred into broad daylight. At first I thought the beacon had gone back on and was casting its electric light into the liquid mass. I was mistaken, and after a hasty examination I discovered my error.

The Nautilus had drifted into the midst of some phosphorescent strata, which, in this darkness, came off as positively dazzling. This effect was caused by myriads of tiny, luminous animals whose brightness increased when they glided over the metal hull of our submersible. In the midst of these luminous sheets of water, I then glimpsed flashes of light, like those seen inside a blazing furnace from streams of molten lead or from masses of metal brought to a white heat--flashes so intense that certain areas of the light became shadows by comparison, in a fiery setting from which every shadow should seemingly have been banished. No, this was no longer the calm emission of our usual lighting! This light throbbed with unprecedented vigor and activity! You sensed that it was alive!

In essence, it was a cluster of countless open-sea infusoria, of noctiluca an eighth of an inch wide, actual globules of transparent jelly equipped with a threadlike tentacle, up to 25,000 of which have been counted in thirty cubic centimeters of water. And the power of their light was increased by those glimmers unique to medusas, starfish, common jellyfish, angel-wing clams, and other phosphorescent zoophytes, which were saturated with grease from organic matter decomposed by the sea, and perhaps with mucus secreted by fish.

For several hours the Nautilus drifted in this brilliant tide, and our wonderment grew when we saw huge marine animals cavorting in it, like the fire-dwelling salamanders of myth. In the midst of these flames that didn't burn, I could see swift, elegant porpoises, the tireless pranksters of the seas, and sailfish three meters long, those shrewd heralds of hurricanes, whose fearsome broadswords sometimes banged against the lounge window. Then smaller fish appeared: miscellaneous triggerfish, leather jacks, unicornfish, and a hundred others that left stripes on this luminous atmosphere in their course.

Some magic lay behind this dazzling sight! Perhaps some atmospheric condition had intensified this phenomenon? Perhaps a storm had been unleashed on the surface of the waves? But only a few meters down, the Nautilus felt no tempest's fury, and the ship rocked peacefully in the midst of the calm waters.

And so it went, some new wonder constantly delighting us. Conseil observed and classified his zoophytes, articulates, mollusks, and fish. The days passed quickly, and I no longer kept track of them. Ned, as usual, kept looking for changes of pace from our standard fare. Like actual snails, we were at home in our shell, and I can vouch that it's easy to turn into a full-fledged snail.

So this way of living began to seem simple and natural to us, and we no longer envisioned a different lifestyle on the surface of the planet earth, when something happened to remind us of our strange circumstances.
