After some minutes a sharp hissing reached my ears. I felt a distinct sensation of cold rising from my feet to my chest. Apparently a stopcock inside the boat was letting in water from outside, which overran us and soon filled up the room. Contrived in the Nautilus’s side, a second door then opened. We were lit by a subdued light. An instant later our feet were treading the bottom of the sea. And now, how can I convey the impressions left on me by this stroll under the waters. Words are powerless to describe such wonders! When even the painter’s brush can’t depict the effects unique to the liquid element, how can the writer’s pen hope to reproduce them? Captain Nemo walked in front, and his companion followed us a few steps to the rear. Conseil and I stayed next to each other, as if daydreaming that through our metal carapaces, a little polite conversation might still be possible! Already I no longer felt the bulkiness of my clothes, footwear, and air tank, nor the weight of the heavy sphere inside which my head was rattling like an almond in its shell. Once immersed in water, all these objects lost a part of their weight equal to the weight of the liquid they displaced, and thanks to this law of physics discovered by Archimedes, I did just fine. I was no longer an inert mass, and I had, comparatively speaking, great freedom of movement. Lighting up the seafloor even thirty feet beneath the surface of the ocean, the sun astonished me with its power. The solar rays easily crossed this aqueous mass and dispersed its dark colors. I could easily distinguish objects 100 meters away. Farther on, the bottom was tinted with fine shades of ultramarine; then, off in the distance, it turned blue and faded in the midst of a hazy darkness. Truly, this water surrounding me was just a kind of air, denser than the atmosphere on land but almost as transparent. Above me I could see the calm surface of the ocean. We were walking on sand that was fine-grained and smooth, not wrinkled like beach sand, which preserves the impressions left by the waves. This dazzling carpet was a real mirror, throwing back the sun’s rays with startling intensity. The outcome: an immense vista of reflections that penetrated every liquid molecule. Will anyone believe me if I assert that at this thirty-foot depth, I could see as if it was broad daylight?
