"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 degrees centigrade, which at this depth seemed to be a temperature common to all latitudes.
On November 26, at three o'clock in the morning, the Nautilus cleared the Tropic of Cancer at longitude 172 degrees. On the 27th it passed in sight of the Hawaiian Islands, where the famous Captain Cook met his death on February 14, 1779. By then we had fared 4,860 leagues from our starting point. When I arrived on the platform that morning, I saw the Island of Hawaii two miles to leeward, the largest of the seven islands making up this group. I could clearly distinguish the tilled soil on its outskirts, the various mountain chains running parallel with its coastline, and its volcanoes, crowned by Mauna Kea, whose elevation is 5,000 meters above sea level. Among other specimens from these waterways, our nets brought up some peacock-tailed flabellarian coral, polyps flattened into stylish shapes and unique to this part of the ocean.
The Nautilus kept to its southeasterly heading. On December 1 it cut the equator at longitude 142 degrees, and on the 4th of the same month, after a quick crossing marked by no incident, we raised the Marquesas Islands. Three miles off, in latitude 8 degrees 57' south and longitude 139 degrees 32' west, I spotted Martin Point on Nuku Hiva, chief member of this island group that belongs to France. I could make out only its wooded mountains on the horizon, because Captain Nemo hated to hug shore. There our nets brought up some fine fish samples: dolphinfish with azure fins, gold tails, and flesh that's unrivaled in the entire world, wrasse from the genus Hologymnosus that were nearly denuded of scales but exquisite in flavor, knifejaws with bony beaks, yellowish albacore that were as tasty as bonito, all fish worth classifying in the ship's pantry.
After leaving these delightful islands to the protection of the French flag, the Nautilus covered about 2,000 miles from December 4 to the 11th. Its navigating was marked by an encounter with an immense school of squid, unusual mollusks that are near neighbors of the cuttlefish. French fishermen give them the name "cuckoldfish," and they belong to the class Cephalopoda, family Dibranchiata, consisting of themselves together with cuttlefish and argonauts. The naturalists of antiquity made a special study of them, and these animals furnished many ribald figures of speech for soapbox orators in the Greek marketplace, as well as excellent dishes for the tables of rich citizens, if we're to believe Athenaeus, a Greek physician predating Galen.
It was during the night of December 9-10 that the Nautilus encountered this army of distinctly nocturnal mollusks. They numbered in the millions. They were migrating from the temperate zones toward zones still warmer, following the itineraries of herring and sardines. We stared at them through our thick glass windows: they swam backward with tremendous speed, moving by means of their locomotive tubes, chasing fish and mollusks, eating the little ones, eaten by the big ones, and tossing in indescribable confusion the ten feet that nature has rooted in their heads like a hairpiece of pneumatic snakes. Despite its speed, the Nautilus navigated for several hours in the midst of this school of animals, and its nets brought up an incalculable number, among which I recognized all nine species that Professor Orbigny has classified as native to the Pacific Ocean.
During this crossing, the sea continually lavished us with the most marvelous sights. Its variety was infinite. It changed its setting and decor for the mere pleasure of our eyes, and we were called upon not simply to contemplate the works of our Creator in the midst of the liquid element, but also to probe the ocean's most daunting mysteries.
During the day of December 11, I was busy reading in the main lounge. Ned Land and Conseil were observing the luminous waters through the gaping panels. The Nautilus was motionless. Its ballast tanks full, it was sitting at a depth of 1,000 meters in a comparatively unpopulated region of the ocean where only larger fish put in occasional appearances.
Just then I was studying a delightful book by Jean Macé, The Servants of the Stomach, and savoring its ingenious teachings, when Conseil interrupted my reading.
"Would master kindly come here for an instant?" he said to me in an odd voice.
"What is it, Conseil?"
"It's something that master should see."
I stood up, went, leaned on my elbows before the window, and I saw it.
In the broad electric daylight, an enormous black mass, quite motionless, hung suspended in the midst of the waters. I observed it carefully, trying to find out the nature of this gigantic cetacean. Then a sudden thought crossed my mind.
"A ship!" I exclaimed.
"Yes," the Canadian replied, "a disabled craft that's sinking straight down!"
Ned Land was not mistaken. We were in the presence of a ship whose severed shrouds still hung from their clasps. Its hull looked in good condition, and it must have gone under only a few hours before. The stumps of three masts, chopped off two feet above the deck, indicated a flooding ship that had been forced to sacrifice its masting. But it had heeled sideways, filling completely, and it was listing to port even yet. A sorry sight, this carcass lost under the waves, but sorrier still was the sight on its deck, where, lashed with ropes to prevent their being washed overboard, some human corpses still lay! I counted four of them--four men, one still standing at the helm-- then a woman, halfway out of a skylight on the afterdeck, holding a child in her arms. This woman was young. Under the brilliant lighting of the Nautilus's rays, I could make out her features, which the water hadn't yet decomposed. With a supreme effort, she had lifted her child above her head, and the poor little creature's arms were still twined around its mother's neck! The postures of the four seamen seemed ghastly to me, twisted from convulsive movements, as if making a last effort to break loose from the ropes that bound them to their ship. And the helmsman, standing alone, calmer, his face smooth and serious, his grizzled hair plastered to his brow, his hands clutching the wheel, seemed even yet to be guiding his wrecked three-master through the ocean depths!
What a scene! We stood dumbstruck, hearts pounding, before this shipwreck caught in the act, as if it had been photographed in its final moments, so to speak! And already I could see enormous sharks moving in, eyes ablaze, drawn by the lure of human flesh!
Meanwhile, turning, the Nautilus made a circle around the sinking ship, and for an instant I could read the board on its stern:
The Florida
Sunderland, England
CHAPTER 19
Vanikoro
THIS DREADFUL SIGHT was the first of a whole series of maritime catastrophes that the Nautilus would encounter on its run. When it plied more heavily traveled seas, we often saw wrecked hulls rotting in midwater, and farther down, cannons, shells, anchors, chains, and a thousand other iron objects rusting away.
Meanwhile, continuously swept along by the Nautilus, where we lived in near isolation, we raised the Tuamotu Islands on December 11, that old "dangerous group" associated with the French global navigator Commander Bougainville; it stretches from Ducie Island to Lazareff Island over an area of 500 leagues from the east-southeast to the west-northwest, between latitude 13 degrees 30' and 23 degrees 50' south, and between longitude 125 degrees 30' and 151 degrees 30' west. This island group covers a surface area of 370 square leagues, and it's made up of some sixty subgroups, among which we noted the Gambier group, which is a French protectorate. These islands are coral formations. Thanks to the work of polyps, a slow but steady upheaval will someday connect these islands to each other. Later on, this new island will be fused to its neighboring island groups, and a fifth continent will stretch from New Zealand and New Caledonia as far as the Marquesas Islands.
The day I expounded this theory to Captain Nemo, he answered me coldly:
"The earth doesn't need new continents, but new men!"
Sailors' luck led the Nautilus straight to Reao Island, one of the most unusual in this group, which was discovered in 1822 by Captain Bell aboard the Minerva. So I was able to study the madreporic process that has created the islands in this ocean.
Madrepores, which one must guard against confusing with precious coral, clothe their tissue in a limestone crust, and their variations in structure have led my famous mentor Professor Milne-Edwards to classify them into five divisions. The tiny microscopic animals that secrete this polypary live by the billions in the depths of their cells. Their limestone deposits build up into rocks, reefs, islets, islands. In some places, they form atolls, a circular ring surrounding a lagoon or small inner lake that gaps place in contact with the sea. Elsewhere, they take the shape of barrier reefs, such as those that exist along the coasts of New Caledonia and several of the Tuamotu Islands. In still other localities, such as Réunion Island and the island of Mauritius, they build fringing reefs, high, straight walls next to which the ocean's depth is considerable.
While cruising along only a few cable lengths from the underpinning of Reao Island, I marveled at the gigantic piece of work accomplished by these microscopic laborers. These walls were the express achievements of madrepores known by the names fire coral, finger coral, star coral, and stony coral. These polyps grow exclusively in the agitated strata at the surface of the sea, and so it's in the upper reaches that they begin these substructures, which sink little by little together with the secreted rubble binding them. This, at least, is the theory of Mr. Charles Darwin, who thus explains the formation of atolls--a theory superior, in my view, to the one that says these madreporic edifices sit on the summits of mountains or volcanoes submerged a few feet below sea level.
