Aha, I thought, so he ventures into the Mediterranean? “—1.018 for the waters of the Ionian Sea, and 1.029 for the waters of the Adriatic.” Assuredly, the Nautilus didn’t avoid the heavily traveled seas of Europe, and from this insight I concluded that the ship would take us back—perhaps very soon—to more civilized shores. I expected Ned Land to greet this news with unfeigned satisfaction. 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!
