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° 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:

“Salts,” he said, “fill the sea in considerable quantities, professor, and if you removed all its dissolved saline content, you’d create a mass measuring 4,500,000 cubic leagues, which if it were spread all over the globe, would form a layer more than ten meters high. And don’t think that the presence of these salts is due merely to some whim of nature. No. They make ocean water less open to evaporation and prevent winds from carrying off excessive amounts of steam, which, when condensing, would submerge the temperate zones. Salts play a leading role, the role of stabilizer for the general ecology of the globe!”

Captain Nemo stopped, straightened up, took a few steps along the platform, and returned to me:

“As for those billions of tiny animals,” he went on, “those infusoria that live by the millions in one droplet of water, 800,000 of which are needed to weigh one milligram, their role is no less important. They absorb the marine salts, they assimilate the solid elements in the water, and since they create coral and madrepores, they’re the true builders of limestone continents! And so, after they’ve finished depriving our water drop of its mineral nutrients, the droplet gets lighter, rises to the surface, there absorbs more salts left behind through evaporation, gets heavier, sinks again, and brings those tiny animals new elements to absorb. The outcome: a double current, rising and falling, constant movement, constant life! More intense than on land, more abundant, more infinite, such life blooms in every part of this ocean, an element fatal to man, they say, but vital to myriads of animals—and to me!”

When Captain Nemo spoke in this way, he was transfigured, and he filled me with extraordinary excitement.

“There,” he added, “out there lies true existence! And I can imagine the founding of nautical towns, clusters of underwater households that, like the Nautilus, would return to the surface of the sea to breathe each morning, free towns if ever there were, independent cities! Then again, who knows whether some tyrant . . .”

Captain Nemo finished his sentence with a vehement gesture. Then, addressing me directly, as if to drive away an ugly thought:

“Professor Aronnax,” he asked me, “do you know the depth of the ocean floor?”

“At least, Captain, I know what the major soundings tell us.”

“Could you quote them to me, so I can double–check them as the need arises?”

“Here,” I replied, “are a few of them that stick in my memory. If I’m not mistaken, an average depth of 8,200 meters was found in the north Atlantic, and 2,500 meters in the Mediterranean. The most remarkable soundings were taken in the south Atlantic near the 35th parallel, and they gave 12,000 meters, 14,091 meters, and 15,149 meters. All in all, it’s estimated that if the sea bottom were made level, its average depth would be about seven kilometers.”

“Well, professor,” Captain Nemo replied, “we’ll show you better than that, I hope. As for the average depth of this part of the Pacific, I’ll inform you that it’s a mere 4,000 meters.”

This said, Captain Nemo headed to the hatch and disappeared down the ladder. I followed him and went back to the main lounge. The propeller was instantly set in motion, and the log gave our speed as twenty miles per hour.

Over the ensuing days and weeks, Captain Nemo was very frugal with his visits. I saw him only at rare intervals. His chief officer regularly fixed the positions I found reported on the chart, and in such a way that I could exactly plot the Nautilus’s course.

Conseil and Land spent the long hours with me. Conseil had told his friend about the wonders of our undersea stroll, and the Canadian was sorry he hadn’t gone along. But I hoped an opportunity would arise for a visit to the forests of Oceania.

Almost every day the panels in the lounge were open for some hours, and our eyes never tired of probing the mysteries of the underwater world.

The Nautilus’s general heading was southeast, and it stayed at a depth between 100 and 150 meters. However, from Lord–knows–what whim, one day it did a diagonal dive by means of its slanting fins, reaching strata located 2,000 meters underwater. The thermometer indicated a temperature of 4.25° centigrade, which at this depth seemed to be a temperature common to all latitudes.

By the next morning, November 18, I was fully recovered from my exhaustion of the day before, and I climbed onto the platform just as the Nautilus’s chief officer was pronouncing his daily phrase. It then occurred to me that these words either referred to the state of the sea, or that they meant: “There’s nothing in sight.”

And in truth, the ocean was deserted. Not a sail on the horizon. The tips of Crespo Island had disappeared during the night. The sea, absorbing every color of the prism except its blue rays, reflected the latter in every direction and sported a wonderful indigo tint. The undulating waves regularly took on the appearance of watered silk with wide stripes.

I was marveling at this magnificent ocean view when Captain Nemo appeared. He didn’t seem to notice my presence and began a series of astronomical observations. Then, his operations finished, he went and leaned his elbows on the beacon housing, his eyes straying over the surface of the ocean.

Meanwhile some twenty of the Nautilus’s sailors—all energetic, well–built fellows—climbed onto the platform. They had come to pull up the nets left in our wake during the night. These seamen obviously belonged to different nationalities, although indications of European physical traits could be seen in them all. If I’m not mistaken, I recognized some Irishmen, some Frenchmen, a few Slavs, and a native of either Greece or Crete. Even so, these men were frugal of speech and used among themselves only that bizarre dialect whose origin I couldn’t even guess. So I had to give up any notions of questioning them.

The nets were hauled on board. They were a breed of trawl resembling those used off the Normandy coast, huge pouches held half open by a floating pole and a chain laced through the lower meshes. Trailing in this way from these iron glove makers, the resulting receptacles scoured the ocean floor and collected every marine exhibit in their path. That day they gathered up some unusual specimens from these fish–filled waterways: anglerfish whose comical movements qualify them for the epithet “clowns,” black Commerson anglers equipped with their antennas, undulating triggerfish encircled by little red bands, bloated puffers whose venom is extremely insidious, some olive–hued lampreys, snipefish covered with silver scales, cutlass fish whose electrocuting power equals that of the electric eel and the electric ray, scaly featherbacks with brown crosswise bands, greenish codfish, several varieties of goby, etc.; finally, some fish of larger proportions: a one–meter jack with a prominent head, several fine bonito from the genus Scomber decked out in the colors blue and silver, and three magnificent tuna whose high speeds couldn’t save them from our trawl.

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.”

At a depth of ten meters, we walked amid a swarm of small fish from every species, more numerous than birds in the air, more agile too; but no aquatic game worthy of a gunshot had yet been offered to our eyes.

Just then I saw the captain’s weapon spring to his shoulder and track a moving object through the bushes. A shot went off, I heard a faint hissing, and an animal dropped a few paces away, literally struck by lightning.

It was a magnificent sea otter from the genus Enhydra, the only exclusively marine quadruped. One and a half meters long, this otter had to be worth a good high price. Its coat, chestnut brown above and silver below, would have made one of those wonderful fur pieces so much in demand in the Russian and Chinese markets; the fineness and luster of its pelt guaranteed that it would go for at least ₣2,000. I was full of wonderment at this unusual mammal, with its circular head adorned by short ears, its round eyes, its white whiskers like those on a cat, its webbed and clawed feet, its bushy tail. Hunted and trapped by fishermen, this valuable carnivore has become extremely rare, and it takes refuge chiefly in the northernmost parts of the Pacific, where in all likelihood its species will soon be facing extinction.

Captain Nemo’s companion picked up the animal, loaded it on his shoulder, and we took to the trail again.

For an hour plains of sand unrolled before our steps. Often the seafloor rose to within two meters of the surface of the water. I could then see our images clearly mirrored on the underside of the waves, but reflected upside down: above us there appeared an identical band that duplicated our every movement and gesture; in short, a perfect likeness of the quartet near which it walked, but with heads down and feet in the air.

Another unusual effect. Heavy clouds passed above us, forming and fading swiftly. But after thinking it over, I realized that these so–called clouds were caused simply by the changing densities of the long ground swells, and I even spotted the foaming “white caps” that their breaking crests were proliferating over the surface of the water. Lastly, I couldn’t help seeing the actual shadows of large birds passing over our heads, swiftly skimming the surface of the sea.

On this occasion I witnessed one of the finest gunshots ever to thrill the marrow of a hunter. A large bird with a wide wingspan, quite clearly visible, approached and hovered over us. When it was just a few meters above the waves, Captain Nemo’s companion took aim and fired. The animal dropped, electrocuted, and its descent brought it within reach of our adroit hunter, who promptly took possession of it. It was an albatross of the finest species, a wonderful specimen of these open–sea fowl.

This incident did not interrupt our walk. For two hours we were sometimes led over plains of sand, sometimes over prairies of seaweed that were quite arduous to cross. In all honesty, I was dead tired by the time I spotted a hazy glow half a mile away, cutting through the darkness of the waters. It was the Nautilus’s beacon. Within twenty minutes we would be on board, and there I could breathe easy again—because my tank’s current air supply seemed to be quite low in oxygen. But I was reckoning without an encounter that slightly delayed our arrival.

I was lagging behind some twenty paces when I saw Captain Nemo suddenly come back toward me. With his powerful hands he sent me buckling to the ground, while his companion did the same to Conseil. At first I didn’t know what to make of this sudden assault, but I was reassured to observe the captain lying motionless beside me.

I was stretched out on the seafloor directly beneath some bushes of algae, when I raised my head and spied two enormous masses hurtling by, throwing off phosphorescent glimmers.

My blood turned cold in my veins! I saw that we were under threat from a fearsome pair of sharks. They were blue sharks, dreadful man–eaters with enormous tails, dull, glassy stares, and phosphorescent matter oozing from holes around their snouts. They were like monstrous fireflies that could thoroughly pulverize a man in their iron jaws! I don’t know if Conseil was busy with their classification, but as for me, I looked at their silver bellies, their fearsome mouths bristling with teeth, from a viewpoint less than scientific—more as a victim than as a professor of natural history.

Luckily these voracious animals have poor eyesight. They went by without noticing us, grazing us with their brownish fins; and miraculously, we escaped a danger greater than encountering a tiger deep in the jungle.

Half an hour later, guided by its electric trail, we reached the Nautilus. The outside door had been left open, and Captain Nemo closed it after we reentered the first cell. Then he pressed a button. I heard pumps operating within the ship, I felt the water lowering around me, and in a few moments the cell was completely empty. The inside door opened, and we passed into the wardrobe.

There our diving suits were removed, not without difficulty; and utterly exhausted, faint from lack of food and rest, I repaired to my stateroom, full of wonder at this startling excursion on the bottom of the sea.

How long I was sunk in this torpor I cannot estimate; but when I awoke, it seemed as if the sun were settling toward the horizon. Captain Nemo was already up, and I had started to stretch my limbs, when an unexpected apparition brought me sharply to my feet.

A few paces away, a monstrous, meter–high sea spider was staring at me with beady eyes, poised to spring at me. Although my diving suit was heavy enough to protect me from this animal’s bites, I couldn’t keep back a shudder of horror. Just then Conseil woke up, together with the Nautilus’s sailor. Captain Nemo alerted his companion to this hideous crustacean, which a swing of the rifle butt quickly brought down, and I watched the monster’s horrible legs writhing in dreadful convulsions.

This encounter reminded me that other, more daunting animals must be lurking in these dark reaches, and my diving suit might not be adequate protection against their attacks. Such thoughts hadn’t previously crossed my mind, and I was determined to keep on my guard. Meanwhile I had assumed this rest period would be the turning point in our stroll, but I was mistaken; and instead of heading back to the Nautilus, Captain Nemo continued his daring excursion.

The seafloor kept sinking, and its significantly steeper slope took us to greater depths. It must have been nearly three o’clock when we reached a narrow valley gouged between high, vertical walls and located 150 meters down. Thanks to the perfection of our equipment, we had thus gone ninety meters below the limit that nature had, until then, set on man’s underwater excursions.

I say 150 meters, although I had no instruments for estimating this distance. But I knew that the sun’s rays, even in the clearest seas, could reach no deeper. So at precisely this point the darkness became profound. Not a single object was visible past ten paces. Consequently, I had begun to grope my way when suddenly I saw the glow of an intense white light. Captain Nemo had just activated his electric device. His companion did likewise. Conseil and I followed suit. By turning a switch, I established contact between the induction coil and the glass spiral, and the sea, lit up by our four lanterns, was illuminated for a radius of twenty–five meters.

Captain Nemo continued to plummet into the dark depths of this forest, whose shrubbery grew ever more sparse. I observed that vegetable life was disappearing more quickly than animal life. The open–sea plants had already left behind the increasingly arid seafloor, where a prodigious number of animals were still swarming: zoophytes, articulates, mollusks, and fish.

While we were walking, I thought the lights of our Ruhmkorff devices would automatically attract some inhabitants of these dark strata. But if they did approach us, at least they kept at a distance regrettable from the hunter’s standpoint. Several times I saw Captain Nemo stop and take aim with his rifle; then, after sighting down its barrel for a few seconds, he would straighten up and resume his walk.

Finally, at around four o’clock, this marvelous excursion came to an end. A wall of superb rocks stood before us, imposing in its sheer mass: a pile of gigantic stone blocks, an enormous granite cliffside pitted with dark caves but not offering a single gradient we could climb up. This was the underpinning of Crespo Island. This was land.

The captain stopped suddenly. A gesture from him brought us to a halt, and however much I wanted to clear this wall, I had to stop. Here ended the domains of Captain Nemo. He had no desire to pass beyond them. Farther on lay a part of the globe he would no longer tread underfoot.

Our return journey began. Captain Nemo resumed the lead in our little band, always heading forward without hesitation. I noted that we didn’t follow the same path in returning to the Nautilus. This new route, very steep and hence very arduous, quickly took us close to the surface of the sea. But this return to the upper strata wasn’t so sudden that decompression took place too quickly, which could have led to serious organic disorders and given us those internal injuries so fatal to divers. With great promptness, the light reappeared and grew stronger; and the refraction of the sun, already low on the horizon, again ringed the edges of various objects with the entire color spectrum.

At a depth of ten meters, we walked amid a swarm of small fish from every species, more numerous than birds in the air, more agile too; but no aquatic game worthy of a gunshot had yet been offered to our eyes.

Just then I saw the captain’s weapon spring to his shoulder and track a moving object through the bushes. A shot went off, I heard a faint hissing, and an animal dropped a few paces away, literally struck by lightning.

We had finally arrived on the outskirts of this forest, surely one of the finest in Captain Nemo’s immense domains. He regarded it as his own and had laid the same claim to it that, in the first days of the world, the first men had to their forests on land. Besides, who else could dispute his ownership of this underwater property? What other, bolder pioneer would come, ax in hand, to clear away its dark underbrush?

This forest was made up of big treelike plants, and when we entered beneath their huge arches, my eyes were instantly struck by the unique arrangement of their branches—an arrangement that I had never before encountered.

None of the weeds carpeting the seafloor, none of the branches bristling from the shrubbery, crept, or leaned, or stretched on a horizontal plane. They all rose right up toward the surface of the ocean. Every filament or ribbon, no matter how thin, stood ramrod straight. Fucus plants and creepers were growing in stiff perpendicular lines, governed by the density of the element that generated them. After I parted them with my hands, these otherwise motionless plants would shoot right back to their original positions. It was the regime of verticality.

I soon grew accustomed to this bizarre arrangement, likewise to the comparative darkness surrounding us. The seafloor in this forest was strewn with sharp chunks of stone that were hard to avoid. Here the range of underwater flora seemed pretty comprehensive to me, as well as more abundant than it might have been in the arctic or tropical zones, where such exhibits are less common. But for a few minutes I kept accidentally confusing the two kingdoms, mistaking zoophytes for water plants, animals for vegetables. And who hasn’t made the same blunder? Flora and fauna are so closely associated in the underwater world!

I observed that all these exhibits from the vegetable kingdom were attached to the seafloor by only the most makeshift methods. They had no roots and didn’t care which solid objects secured them, sand, shells, husks, or pebbles; they didn’t ask their hosts for sustenance, just a point of purchase. These plants are entirely self–propagating, and the principle of their existence lies in the water that sustains and nourishes them. In place of leaves, most of them sprouted blades of unpredictable shape, which were confined to a narrow gamut of colors consisting only of pink, crimson, green, olive, tan, and brown. There I saw again, but not yet pressed and dried like the Nautilus’s specimens, some peacock’s tails spread open like fans to stir up a cooling breeze, scarlet rosetangle, sea tangle stretching out their young and edible shoots, twisting strings of kelp from the genus Nereocystis that bloomed to a height of fifteen meters, bouquets of mermaid’s cups whose stems grew wider at the top, and a number of other open–sea plants, all without flowers. “It’s an odd anomaly in this bizarre element!” as one witty naturalist puts it. “The animal kingdom blossoms, and the vegetable kingdom doesn’t!”

These various types of shrubbery were as big as trees in the temperate zones; in the damp shade between them, there were clustered actual bushes of moving flowers, hedges of zoophytes in which there grew stony coral striped with twisting furrows, yellowish sea anemone from the genus Caryophylia with translucent tentacles, plus anemone with grassy tufts from the genus Zoantharia; and to complete the illusion, minnows flitted from branch to branch like a swarm of hummingbirds, while there rose underfoot, like a covey of snipe, yellow fish from the genus Lepisocanthus with bristling jaws and sharp scales, flying gurnards, and pinecone fish.

Near one o’clock, Captain Nemo gave the signal to halt. Speaking for myself, I was glad to oblige, and we stretched out beneath an arbor of winged kelp, whose long thin tendrils stood up like arrows.

This short break was a delight. It lacked only the charm of conversation. But it was impossible to speak, impossible to reply. I simply nudged my big copper headpiece against Conseil’s headpiece. I saw a happy gleam in the gallant lad’s eyes, and to communicate his pleasure, he jiggled around inside his carapace in the world’s silliest way.

After four hours of strolling, I was quite astonished not to feel any intense hunger. What kept my stomach in such a good mood I’m unable to say. But, in exchange, I experienced that irresistible desire for sleep that comes over every diver. Accordingly, my eyes soon closed behind their heavy glass windows and I fell into an uncontrollable doze, which until then I had been able to fight off only through the movements of our walking. Captain Nemo and his muscular companion were already stretched out in this clear crystal, setting us a fine naptime example.

How long I was sunk in this torpor I cannot estimate; but when I awoke, it seemed as if the sun were settling toward the horizon. Captain Nemo was already up, and I had started to stretch my limbs, when an unexpected apparition brought me sharply to my feet.

A few paces away, a monstrous, meter–high sea spider was staring at me with beady eyes, poised to spring at me. Although my diving suit was heavy enough to protect me from this animal’s bites, I couldn’t keep back a shudder of horror. Just then Conseil woke up, together with the Nautilus’s sailor. Captain Nemo alerted his companion to this hideous crustacean, which a swing of the rifle butt quickly brought down, and I watched the monster’s horrible legs writhing in dreadful convulsions.
