NIGHT FELL. I went to bed. I slept pretty poorly. Man-eaters played a major role in my dreams. And I found it more or less appropriate that the French word for shark, requin, has its linguistic roots in the word requiem.

The next day at four o'clock in the morning, I was awakened by the steward whom Captain Nemo had placed expressly at my service. I got up quickly, dressed, and went into the lounge.

Captain Nemo was waiting for me.

"Professor Aronnax," he said to me, "are you ready to start?"

"I'm ready."

"Kindly follow me."

"What about my companions, captain?"

"They've been alerted and are waiting for us."

"Aren't we going to put on our diving suits?" I asked.

"Not yet. I haven't let the Nautilus pull too near the coast, and we're fairly well out from the Mannar oysterbank. But I have the skiff ready, and it will take us to the exact spot where we'll disembark, which will save us a pretty long trek. It's carrying our diving equipment, and we'll suit up just before we begin our underwater exploring."

Captain Nemo took me to the central companionway whose steps led to the platform. Ned and Conseil were there, enraptured with the "pleasure trip" getting under way. Oars in position, five of the Nautilus's sailors were waiting for us aboard the skiff, which was moored alongside. The night was still dark. Layers of clouds cloaked the sky and left only a few stars in view. My eyes flew to the side where land lay, but I saw only a blurred line covering three-quarters of the horizon from southwest to northwest. Going up Ceylon's west coast during the night, the Nautilus lay west of the bay, or rather that gulf formed by the mainland and Mannar Island. Under these dark waters there stretched the bank of shellfish, an inexhaustible field of pearls more than twenty miles long.

Captain Nemo, Conseil, Ned Land, and I found seats in the stern of the skiff. The longboat's coxswain took the tiller; his four companions leaned into their oars; the moorings were cast off and we pulled clear.

The skiff headed southward. The oarsmen took their time. I watched their strokes vigorously catch the water, and they always waited ten seconds before rowing again, following the practice used in most navies. While the longboat coasted, drops of liquid flicked from the oars and hit the dark troughs of the waves, pitter-pattering like splashes of molten lead. Coming from well out, a mild swell made the skiff roll gently, and a few cresting billows lapped at its bow.

We were silent. What was Captain Nemo thinking? Perhaps that this approaching shore was too close for comfort, contrary to the Canadian's views in which it still seemed too far away. As for Conseil, he had come along out of simple curiosity.

Near 5:30 the first glimmers of light on the horizon defined the upper lines of the coast with greater distinctness. Fairly flat to the east, it swelled a little toward the south. Five miles still separated it from us, and its beach merged with the misty waters. Between us and the shore, the sea was deserted. Not a boat, not a diver. Profound solitude reigned over this gathering place of pearl fishermen. As Captain Nemo had commented, we were arriving in these waterways a month too soon.

At six o'clock the day broke suddenly, with that speed unique to tropical regions, which experience no real dawn or dusk. The sun's rays pierced the cloud curtain gathered on the easterly horizon, and the radiant orb rose swiftly.

I could clearly see the shore, which featured a few sparse trees here and there.

The skiff advanced toward Mannar Island, which curved to the south. Captain Nemo stood up from his thwart and studied the sea.

At his signal the anchor was lowered, but its chain barely ran because the bottom lay no more than a meter down, and this locality was one of the shallowest spots near the bank of shellfish. Instantly the skiff wheeled around under the ebb tide's outbound thrust.

"Here we are, Professor Aronnax," Captain Nemo then said. "You observe this confined bay? A month from now in this very place, the numerous fishing boats of the harvesters will gather, and these are the waters their divers will ransack so daringly. This bay is felicitously laid out for their type of fishing. It's sheltered from the strongest winds, and the sea is never very turbulent here, highly favorable conditions for diving work. Now let's put on our underwater suits, and we'll begin our stroll."

I didn't reply, and while staring at these suspicious waves, I began to put on my heavy aquatic clothes, helped by the longboat's sailors. Captain Nemo and my two companions suited up as well. None of the Nautilus's men were to go with us on this new excursion.

Soon we were imprisoned up to the neck in india-rubber clothing, and straps fastened the air devices onto our backs. As for the Ruhmkorff device, it didn't seem to be in the picture. Before inserting my head into its copper capsule, I commented on this to the captain.

"Our lighting equipment would be useless to us," the captain answered me. "We won't be going very deep, and the sun's rays will be sufficient to light our way. Besides, it's unwise to carry electric lanterns under these waves. Their brightness might unexpectedly attract certain dangerous occupants of these waterways."

As Captain Nemo pronounced these words, I turned to Conseil and Ned Land. But my two friends had already encased their craniums in their metal headgear, and they could neither hear nor reply.

I had one question left to address to Captain Nemo.

"What about our weapons?" I asked him. "Our rifles?"

"Rifles! What for? Don't your mountaineers attack bears dagger in hand? And isn't steel surer than lead? Here's a sturdy blade. Slip it under your belt and let's be off."

I stared at my companions. They were armed in the same fashion, and Ned Land was also brandishing an enormous harpoon he had stowed in the skiff before leaving the Nautilus.

Then, following the captain's example, I let myself be crowned with my heavy copper sphere, and our air tanks immediately went into action.

An instant later, the longboat's sailors helped us overboard one after the other, and we set foot on level sand in a meter and a half of water. Captain Nemo gave us a hand signal. We followed him down a gentle slope and disappeared under the waves.

There the obsessive fears in my brain left me. I became surprisingly calm again. The ease with which I could move increased my confidence, and the many strange sights captivated my imagination.

The sun was already sending sufficient light under these waves. The tiniest objects remained visible. After ten minutes of walking, we were in five meters of water, and the terrain had become almost flat.

Like a covey of snipe over a marsh, there rose underfoot schools of unusual fish from the genus Monopterus, whose members have no fin but their tail. I recognized the Javanese eel, a genuine eight-decimeter serpent with a bluish gray belly, which, without the gold lines over its flanks, could easily be confused with the conger eel. From the butterfish genus, whose oval bodies are very flat, I observed several adorned in brilliant colors and sporting a dorsal fin like a sickle, edible fish that, when dried and marinated, make an excellent dish known by the name "karawade"; then some sea poachers, fish belonging to the genus Aspidophoroides, whose bodies are covered with scaly armor divided into eight lengthwise sections.

Meanwhile, as the sun got progressively higher, it lit up the watery mass more and more. The seafloor changed little by little. Its fine-grained sand was followed by a genuine causeway of smooth crags covered by a carpet of mollusks and zoophytes. Among other specimens in these two branches, I noted some windowpane oysters with thin valves of unequal size, a type of ostracod unique to the Red Sea and the Indian Ocean, then orange-hued lucina with circular shells, awl-shaped auger shells, some of those Persian murex snails that supply the Nautilus with such wonderful dye, spiky periwinkles fifteen centimeters long that rose under the waves like hands ready to grab you, turban snails with shells made of horn and bristling all over with spines, lamp shells, edible duck clams that feed the Hindu marketplace, subtly luminous jellyfish of the species Pelagia panopyra, and finally some wonderful Oculina flabelliforma, magnificent sea fans that fashion one of the most luxuriant tree forms in this ocean.

In the midst of this moving vegetation, under arbors of water plants, there raced legions of clumsy articulates, in particular some fanged frog crabs whose carapaces form a slightly rounded triangle, robber crabs exclusive to these waterways, and horrible parthenope crabs whose appearance was repulsive to the eye. One animal no less hideous, which I encountered several times, was the enormous crab that Mr. Darwin observed, to which nature has given the instinct and requisite strength to eat coconuts; it scrambles up trees on the beach and sends the coconuts tumbling; they fracture in their fall and are opened by its powerful pincers. Here, under these clear waves, this crab raced around with matchless agility, while green turtles from the species frequenting the Malabar coast moved sluggishly among the crumbling rocks.

Near seven o'clock we finally surveyed the bank of shellfish, where pearl oysters reproduce by the millions. These valuable mollusks stick to rocks, where they're strongly attached by a mass of brown filaments that forbids their moving about. In this respect oysters are inferior even to mussels, to whom nature has not denied all talent for locomotion.

The shellfish Meleagrina, that womb for pearls whose valves are nearly equal in size, has the shape of a round shell with thick walls and a very rough exterior. Some of these shells were furrowed with flaky, greenish bands that radiated down from the top. These were the young oysters. The others had rugged black surfaces, measured up to fifteen centimeters in width, and were ten or more years old.

Captain Nemo pointed to this prodigious heap of shellfish, and I saw that these mines were genuinely inexhaustible, since nature's creative powers are greater than man's destructive instincts. True to those instincts, Ned Land greedily stuffed the finest of these mollusks into a net he carried at his side.

But we couldn't stop. We had to follow the captain, who headed down trails seemingly known only to himself. The seafloor rose noticeably, and when I lifted my arms, sometimes they would pass above the surface of the sea. Then the level of the oysterbank would lower unpredictably. Often we went around tall, pointed rocks rising like pyramids. In their dark crevices huge crustaceans, aiming their long legs like heavy artillery, watched us with unblinking eyes, while underfoot there crept millipedes, bloodworms, aricia worms, and annelid worms, whose antennas and tubular tentacles were incredibly long.

Just then a huge cave opened up in our path, hollowed from a picturesque pile of rocks whose smooth heights were completely hung with underwater flora. At first this cave looked pitch-black to me. Inside, the sun's rays seemed to diminish by degrees. Their hazy transparency was nothing more than drowned light.

Captain Nemo went in. We followed him. My eyes soon grew accustomed to this comparative gloom. I distinguished the unpredictably contoured springings of a vault, supported by natural pillars firmly based on a granite foundation, like the weighty columns of Tuscan architecture. Why had our incomprehensible guide taken us into the depths of this underwater crypt? I would soon find out.

After going down a fairly steep slope, our feet trod the floor of a sort of circular pit. There Captain Nemo stopped, and his hand indicated an object that I hadn't yet noticed.

It was an oyster of extraordinary dimensions, a titanic giant clam, a holy-water font that could have held a whole lake, a basin more than two meters wide, hence even bigger than the one adorning the Nautilus's lounge.

I approached this phenomenal mollusk. Its mass of filaments attached it to a table of granite, and there it grew by itself in the midst of the cave's calm waters. I estimated the weight of this giant clam at 300 kilograms. Hence such an oyster held fifteen kilos of meat, and you'd need the stomach of King Gargantua to eat a couple dozen.

Captain Nemo was obviously familiar with this bivalve's existence. This wasn't the first time he'd paid it a visit, and I thought his sole reason for leading us to this locality was to show us a natural curiosity. I was mistaken. Captain Nemo had an explicit personal interest in checking on the current condition of this giant clam.

The mollusk's two valves were partly open. The captain approached and stuck his dagger vertically between the shells to discourage any ideas about closing; then with his hands he raised the fringed, membrane-filled tunic that made up the animal's mantle.

There, between its leaflike folds, I saw a loose pearl as big as a coconut. Its globular shape, perfect clarity, and wonderful orient made it a jewel of incalculable value. Carried away by curiosity, I stretched out my hand to take it, weigh it, fondle it! But the captain stopped me, signaled no, removed his dagger in one swift motion, and let the two valves snap shut.

I then understood Captain Nemo's intent. By leaving the pearl buried beneath the giant clam's mantle, he allowed it to grow imperceptibly. With each passing year the mollusk's secretions added new concentric layers. The captain alone was familiar with the cave where this wonderful fruit of nature was "ripening"; he alone reared it, so to speak, in order to transfer it one day to his dearly beloved museum. Perhaps, following the examples of oyster farmers in China and India, he had even predetermined the creation of this pearl by sticking under the mollusk's folds some piece of glass or metal that was gradually covered with mother-of-pearl. In any case, comparing this pearl to others I already knew about, and to those shimmering in the captain's collection, I estimated that it was worth at least 10,000,000 francs. It was a superb natural curiosity rather than a luxurious piece of jewelry, because I don't know of any female ear that could handle it.

Our visit to this opulent giant clam came to an end. Captain Nemo left the cave, and we climbed back up the bank of shellfish in the midst of these clear waters not yet disturbed by divers at work.

We walked by ourselves, genuine loiterers stopping or straying as our fancies dictated. For my part, I was no longer worried about those dangers my imagination had so ridiculously exaggerated. The shallows drew noticeably closer to the surface of the sea, and soon, walking in only a meter of water, my head passed well above the level of the ocean. Conseil rejoined me, and gluing his huge copper capsule to mine, his eyes gave me a friendly greeting. But this lofty plateau measured only a few fathoms, and soon we reentered Our Element. I think I've now earned the right to dub it that.

Ten minutes later, Captain Nemo stopped suddenly. I thought he'd called a halt so that we could turn and start back. No. With a gesture he ordered us to crouch beside him at the foot of a wide crevice. His hand motioned toward a spot within the liquid mass, and I looked carefully.

Five meters away a shadow appeared and dropped to the seafloor. The alarming idea of sharks crossed my mind. But I was mistaken, and once again we didn't have to deal with monsters of the deep.

It was a man, a living man, a black Indian fisherman, a poor devil who no doubt had come to gather what he could before harvest time. I saw the bottom of his dinghy, moored a few feet above his head. He would dive and go back up in quick succession. A stone cut in the shape of a sugar loaf, which he gripped between his feet while a rope connected it to his boat, served to lower him more quickly to the ocean floor. This was the extent of his equipment. Arriving on the seafloor at a depth of about five meters, he fell to his knees and stuffed his sack with shellfish gathered at random. Then he went back up, emptied his sack, pulled up his stone, and started all over again, the whole process lasting only thirty seconds.

This diver didn't see us. A shadow cast by our crag hid us from his view. And besides, how could this poor Indian ever have guessed that human beings, creatures like himself, were near him under the waters, eavesdropping on his movements, not missing a single detail of his fishing!

So he went up and down several times. He gathered only about ten shellfish per dive, because he had to tear them from the banks where each clung with its tough mass of filaments. And how many of these oysters for which he risked his life would have no pearl in them!

I observed him with great care. His movements were systematically executed, and for half an hour no danger seemed to threaten him. So I had gotten used to the sight of this fascinating fishing when all at once, just as the Indian was kneeling on the seafloor, I saw him make a frightened gesture, stand, and gather himself to spring back to the surface of the waves.

I understood his fear. A gigantic shadow appeared above the poor diver. It was a shark of huge size, moving in diagonally, eyes ablaze, jaws wide open!

I was speechless with horror, unable to make a single movement.

With one vigorous stroke of its fins, the voracious animal shot toward the Indian, who jumped aside and avoided the shark's bite but not the thrashing of its tail, because that tail struck him across the chest and stretched him out on the seafloor.

This scene lasted barely a few seconds. The shark returned, rolled over on its back, and was getting ready to cut the Indian in half, when Captain Nemo, who was stationed beside me, suddenly stood up. Then he strode right toward the monster, dagger in hand, ready to fight it at close quarters.

Just as it was about to snap up the poor fisherman, the man-eater saw its new adversary, repositioned itself on its belly, and headed swiftly toward him.

I can see Captain Nemo's bearing to this day. Bracing himself, he waited for the fearsome man-eater with wonderful composure, and when the latter rushed at him, the captain leaped aside with prodigious quickness, avoided a collision, and sank his dagger into its belly. But that wasn't the end of the story. A dreadful battle was joined.

The shark bellowed, so to speak. Blood was pouring into the waves from its wounds. The sea was dyed red, and through this opaque liquid I could see nothing else.

Nothing else until the moment when, through a rift in the clouds, I saw the daring captain clinging to one of the animal's fins, fighting the monster at close quarters, belaboring his enemy's belly with stabs of the dagger yet unable to deliver the deciding thrust, in other words, a direct hit to the heart. In its struggles the man-eater churned the watery mass so furiously, its eddies threatened to knock me over.

I wanted to run to the captain's rescue. But I was transfixed with horror, unable to move.
