Twenty Thousand Leagues Under the Seas Part 76

We spent the whole day of February 22 in the Sarga.s.so Sea, where fish that dote on marine plants and crustaceans find plenty to eat.

The next day the ocean resumed its usual appearance.

From this moment on, for nineteen days from February 23 to March 12, the Nautilus stayed in the middle of the Atlantic, hustling us along at a constant speed of 100 leagues every twenty-four hours.

It was obvious that Captain Nemo wanted to carry out his underwater program, and I had no doubt that he intended, after doubling Cape Horn, to return to the Pacific South Seas.

So Ned Land had good reason to worry. In these wide seas empty of islands, it was no longer feasible to jump s.h.i.+p. Nor did we have any way to counter Captain Nemo's whims. We had no choice but to acquiesce; but if we couldn't attain our end through force or cunning, I liked to think we might achieve it through persuasion.

Once this voyage was over, might not Captain Nemo consent to set us free in return for our promise never to reveal his existence?

Our word of honor, which we sincerely would have kept.

However, this delicate question would have to be negotiated with the captain. But how would he receive our demands for freedom?

At the very outset and in no uncertain terms, hadn't he declared that the secret of his life required that we be permanently imprisoned on board the Nautilus? Wouldn't he see my four-month silence as a tacit acceptance of this situation? Would my returning to this subject arouse suspicions that could jeopardize our escape plans, if we had promising circ.u.mstances for trying again later on?

I weighed all these considerations, turned them over in my mind, submitted them to Conseil, but he was as baffled as I was.

In short, although I'm not easily discouraged, I realized that my chances of ever seeing my fellow men again were shrinking by the day, especially at a time when Captain Nemo was recklessly racing toward the south Atlantic!

During those nineteen days just mentioned, no unique incidents distinguished our voyage. I saw little of the captain.

He was at work. In the library I often found books he had left open, especially books on natural history. He had thumbed through my work on the great ocean depths, and the margins were covered with his notes, which sometimes contradicted my theories and formulations.

But the captain remained content with this method of refining my work, and he rarely discussed it with me. Sometimes I heard melancholy sounds reverberating from the organ, which he played very expressively, but only at night in the midst of the most secretive darkness, while the Nautilus slumbered in the wilderness of the ocean.

During this part of our voyage, we navigated on the surface of the waves for entire days. The sea was nearly deserted. A few sailing s.h.i.+ps, laden for the East Indies, were heading toward the Cape of Good Hope. One day we were chased by the longboats of a whaling vessel, which undoubtedly viewed us as some enormous baleen whale of great value.

But Captain Nemo didn't want these gallant gentlemen wasting their time and energy, so he ended the hunt by diving beneath the waters.

This incident seemed to fascinate Ned Land intensely.

I'm sure the Canadian was sorry that these fishermen couldn't harpoon our sheet-iron cetacean and mortally wound it.

During this period the fish Conseil and I observed differed little from those we had already studied in other lat.i.tudes. Chief among them were specimens of that dreadful cartilaginous genus that's divided into three subgenera numbering at least thirty-two species: striped sharks five meters long, the head squat and wider than the body, the caudal fin curved, the back with seven big, black, parallel lines running lengthwise; then perlon sharks, ash gray, pierced with seven gill openings, furnished with a single dorsal fin placed almost exactly in the middle of the body.

Some big dogfish also pa.s.sed by, a voracious species of shark if there ever was one. With some justice, fishermen's yarns aren't to be trusted, but here's what a few of them relate. Inside the corpse of one of these animals there were found a buffalo head and a whole calf; in another, two tuna and a sailor in uniform; in yet another, a soldier with his saber; in another, finally, a horse with its rider.

In candor, none of these sounds like divinely inspired truth.

But the fact remains that not a single dogfish let itself get caught in the Nautilus's nets, so I can't vouch for their voracity.

Schools of elegant, playful dolphin swam alongside for entire days.

They went in groups of five or six, hunting in packs like wolves over the countryside; moreover, they're just as voracious as dogfish, if I can believe a certain Copenhagen professor who says that from one dolphin's stomach, he removed thirteen porpoises and fifteen seals.

True, it was a killer whale, belonging to the biggest known species, whose length sometimes exceeds twenty-four feet. The family Delphinia numbers ten genera, and the dolphins I saw were akin to the genus Delphinorhynchus, remarkable for an extremely narrow muzzle four times as long as the cranium. Measuring three meters, their bodies were black on top, underneath a pinkish white strewn with small, very scattered spots.

From these seas I'll also mention some unusual specimens of croakers, fish from the order Acanthopterygia, family Scienidea. Some authors-- more artistic than scientific--claim that these fish are melodious singers, that their voices in unison put on concerts unmatched by human choristers. I don't say nay, but to my regret these croakers didn't serenade us as we pa.s.sed.

Finally, to conclude, Conseil cla.s.sified a large number of flying fish. Nothing could have made a more unusual sight than the marvelous timing with which dolphins hunt these fish.

Whatever the range of its flight, however evasive its trajectory (even up and over the Nautilus), the hapless flying fish always found a dolphin to welcome it with open mouth. These were either flying gurnards or kitelike sea robins, whose lips glowed in the dark, at night scrawling fiery streaks in the air before plunging into the murky waters like so many shooting stars.

Our navigating continued under these conditions until March 13.

That day the Nautilus was put to work in some depth-sounding experiments that fascinated me deeply.

By then we had fared nearly 13,000 leagues from our starting point in the Pacific high seas. Our position fix placed us in lat.i.tude 45 degrees 37' south and longitude 37 degrees 53' west. These were the same waterways where Captain Denham, aboard the Herald, payed out 14,000 meters of sounding line without finding bottom.

It was here too that Lieutenant Parker, aboard the American frigate Congress, was unable to reach the underwater soil at 15,149 meters.

Captain Nemo decided to take his Nautilus down to the lowest depths in order to double-check these different soundings.

I got ready to record the results of this experiment.

The panels in the lounge opened, and maneuvers began for reaching those strata so prodigiously far removed.

It was apparently considered out of the question to dive by filling the ballast tanks. Perhaps they wouldn't sufficiently increase the Nautilus's specific gravity. Moreover, in order to come back up, it would be necessary to expel the excess water, and our pumps might not have been strong enough to overcome the outside pressure.

Captain Nemo decided to make for the ocean floor by submerging on an appropriately gradual diagonal with the help of his side fins, which were set at a 45 degrees angle to the Nautilus's waterline.

Then the propeller was brought to its maximum speed, and its four blades churned the waves with indescribable violence.

Under this powerful thrust the Nautilus's hull quivered like a resonating chord, and the s.h.i.+p sank steadily under the waters.

Stationed in the lounge, the captain and I watched the needle swerving swiftly over the pressure gauge. Soon we had gone below the livable zone where most fish reside. Some of these animals can thrive only at the surface of seas or rivers, but a minority can dwell at fairly great depths. Among the latter I observed a species of dogfish called the cow shark that's equipped with six respiratory slits, the telescope fish with its enormous eyes, the armored gurnard with gray thoracic fins plus black pectoral fins and a breastplate protected by pale red slabs of bone, then finally the grenadier, living at a depth of 1,200 meters, by that point tolerating a pressure of 120 atmospheres.

I asked Captain Nemo if he had observed any fish at more considerable depths.

"Fish? Rarely!" he answered me. "But given the current state of marine science, who are we to presume, what do we really know of these depths?"

"Just this, captain. In going toward the ocean's lower strata, we know that vegetable life disappears more quickly than animal life.

We know that moving creatures can still be encountered where water plants no longer grow. We know that oysters and pilgrim scallops live in 2,000 meters of water, and that Admiral McClintock, England's hero of the polar seas, pulled in a live sea star from a depth of 2,500 meters.

We know that the crew of the Royal Navy's Bulldog fished up a starfish from 2,620 fathoms, hence from a depth of more than one vertical league.

Would you still say, Captain Nemo, that we really know nothing?"

"No, professor," the captain replied, "I wouldn't be so discourteous.

Yet I'll ask you to explain how these creatures can live at such depths?"

"I explain it on two grounds," I replied. "In the first place, because vertical currents, which are caused by differences in the water's salinity and density, can produce enough motion to sustain the rudimentary lifestyles of sea lilies and starfish."

"True," the captain put in.

"In the second place, because oxygen is the basis of life, and we know that the amount of oxygen dissolved in salt water increases rather than decreases with depth, that the pressure in these lower strata helps to concentrate their oxygen content."

"Oho! We know that, do we?" Captain Nemo replied in a tone of mild surprise. "Well, professor, we have good reason to know it because it's the truth. I might add, in fact, that the air bladders of fish contain more nitrogen than oxygen when these animals are caught at the surface of the water, and conversely, more oxygen than nitrogen when they're pulled up from the lower depths.

Which bears out your formulation. But let's continue our observations."

My eyes flew back to the pressure gauge. The instrument indicated a depth of 6,000 meters. Our submergence had been going on for an hour.

The Nautilus slid downward on its slanting fins, still sinking.

These deserted waters were wonderfully clear, with a transparency impossible to convey. An hour later we were at 13,000 meters-- about three and a quarter vertical leagues--and the ocean floor was nowhere in sight.

However, at 14,000 meters I saw blackish peaks rising in the midst of the waters. But these summits could have belonged to mountains as high or even higher than the Himalayas or Mt. Blanc, and the extent of these depths remained incalculable.

Despite the powerful pressures it was undergoing, the Nautilus sank still deeper. I could feel its sheet-iron plates trembling down to their riveted joins; metal bars arched; bulkheads groaned; the lounge windows seemed to be warping inward under the water's pressure.

And this whole st.u.r.dy mechanism would surely have given way, if, as its captain had said, it weren't capable of resisting like a solid block.

While grazing these rocky slopes lost under the waters, I still spotted some seash.e.l.ls, tube worms, lively annelid worms from the genus Spirorbis, and certain starfish specimens.

But soon these last representatives of animal life vanished, and three vertical leagues down, the Nautilus pa.s.sed below the limits of underwater existence just as an air balloon rises above the breathable zones in the sky. We reached a depth of 16,000 meters-- four vertical leagues--and by then the Nautilus's plating was tolerating a pressure of 1,600 atmospheres, in other words, 1,600 kilograms per each square centimeter on its surface!

"What an experience!" I exclaimed. "Traveling these deep regions where no man has ever ventured before! Look, captain!

Look at these magnificent rocks, these uninhabited caves, these last global haunts where life is no longer possible!

What unheard-of scenery, and why are we reduced to preserving it only as a memory?"

"Would you like," Captain Nemo asked me, "to bring back more than just a memory?"

"What do you mean?"

"I mean that nothing could be easier than taking a photograph of this underwater region!"
