While grazing these rocky slopes lost under the waters, I still spotted some seashells, tube worms, lively annelid worms from the genus Spirorbis, and certain starfish specimens. But soon these last representatives of animal life vanished, and three vertical leagues down, the Nautilus passed below the limits of underwater existence just as an air balloon rises above the breathable zones in the sky. We reached a depth of 16,000 meters—four vertical leagues—and by then the Nautilus’s plating was tolerating a pressure of 1,600 atmospheres, in other words, 1,600 kilograms per each square centimeter on its surface! “What an experience!” I exclaimed. “Traveling these deep regions where no man has ever ventured before! Look, captain! Look at these magnificent rocks, these uninhabited caves, these last global haunts where life is no longer possible! What unheard-of scenery, and why are we reduced to preserving it only as a memory?” “Would you like,” Captain Nemo asked me, “to bring back more than just a memory?” “What do you mean?” “I mean that nothing could be easier than taking a photograph of this underwater region!” Before I had time to express the surprise this new proposition caused me, a camera was carried into the lounge at Captain Nemo’s request. The liquid setting, electrically lit, unfolded with perfect clarity through the wide-open panels. No shadows, no blurs, thanks to our artificial light. Not even sunshine could have been better for our purposes. With the thrust of its propeller curbed by the slant of its fins, the Nautilus stood still. The camera was aimed at the scenery on the ocean floor, and in a few seconds we had a perfect negative. I attach a print of the positive. In it you can view these primordial rocks that have never seen the light of day, this nether granite that forms the powerful foundation of our globe, the deep caves cut into the stony mass, the outlines of incomparable distinctness whose far edges stand out in black as if from the brush of certain Flemish painters. In the distance is a mountainous horizon, a wondrously undulating line that makes up the background of this landscape. The general effect of these smooth rocks is indescribable: black, polished, without moss or other blemish, carved into strange shapes, sitting firmly on a carpet of sand that sparkled beneath our streams of electric light. Meanwhile, his photographic operations over, Captain Nemo told me: “Let’s go back up, professor. We mustn’t push our luck and expose the Nautilus too long to these pressures.” “Let’s go back up!” I replied. “Hold on tight.” Before I had time to realize why the captain made this recommendation, I was hurled to the carpet.
