I estimate that this cast of the net brought in more than 1,000 pounds of fish. It was a fine catch but not surprising. In essence, these nets stayed in our wake for several hours, incarcerating an entire aquatic world in prisons made of thread. So we were never lacking in provisions of the highest quality, which the Nautilus’s speed and the allure of its electric light could continually replenish. These various exhibits from the sea were immediately lowered down the hatch in the direction of the storage lockers, some to be eaten fresh, others to be preserved. After its fishing was finished and its air supply renewed, I thought the Nautilus would resume its underwater excursion, and I was getting ready to return to my stateroom, when Captain Nemo turned to me and said without further preamble: “Look at this ocean, professor! Doesn’t it have the actual gift of life? Doesn’t it experience both anger and affection? Last evening it went to sleep just as we did, and there it is, waking up after a peaceful night!” No hellos or good mornings for this gent! You would have thought this eccentric individual was simply continuing a conversation we’d already started! “See!” he went on. “It’s waking up under the sun’s caresses! It’s going to relive its daily existence! What a fascinating field of study lies in watching the play of its organism. It owns a pulse and arteries, it has spasms, and I side with the scholarly Commander Maury, who discovered that it has a circulation as real as the circulation of blood in animals.” I’m sure that Captain Nemo expected no replies from me, and it seemed pointless to pitch in with “Ah yes,” “Exactly,” or “How right you are!” Rather, he was simply talking to himself, with long pauses between sentences. He was meditating out loud. “Yes,” he said, “the ocean owns a genuine circulation, and to start it going, the Creator of All Things has only to increase its heat, salt, and microscopic animal life. In essence, heat creates the different densities that lead to currents and countercurrents. Evaporation, which is nil in the High Arctic regions and very active in equatorial zones, brings about a constant interchange of tropical and polar waters. What’s more, I’ve detected those falling and rising currents that make up the ocean’s true breathing. I’ve seen a molecule of salt water heat up at the surface, sink into the depths, reach maximum density at -2 degrees centigrade, then cool off, grow lighter, and rise again. At the poles you’ll see the consequences of this phenomenon, and through this law of farseeing nature, you’ll understand why water can freeze only at the surface!” As the captain was finishing his sentence, I said to myself: “The pole! Is this brazen individual claiming he’ll take us even to that location?” Meanwhile the captain fell silent and stared at the element he had studied so thoroughly and unceasingly. Then, going on:
