Twenty Thousand Leagues Under the Seas Part 74

"Underground!" I exclaimed. "And the Nautilus is still floating?"

"It always floats."

"But I don't understand!"

"Wait a little while. Our beacon is about to go on, and if you want some light on the subject, you'll be satisfied."

I set foot on the platform and waited. The darkness was so profound I couldn't see even Captain Nemo. However, looking at the zenith directly overhead, I thought I caught sight of a feeble glimmer, a sort of twilight filtering through a circular hole.

Just then the beacon suddenly went on, and its intense brightness made that hazy light vanish.

This stream of electricity dazzled my eyes, and after momentarily shutting them, I looked around. The Nautilus was stationary.

It was floating next to an embankment shaped like a wharf.

As for the water now buoying the ship, it was a lake completely encircled by an inner wall about two miles in diameter, hence six miles around.

Its level--as indicated by the pressure gauge--would be the same as the outside level, because some connection had to exist between this lake and the sea. Slanting inward over their base, these high walls converged to form a vault shaped like an immense upside-down funnel that measured 500 or 600 meters in height.

At its summit there gaped the circular opening through which I had detected that faint glimmer, obviously daylight.

Before more carefully examining the interior features of this enormous cavern, and before deciding if it was the work of nature or humankind, I went over to Captain Nemo.

"Where are we?" I said.

"In the very heart of an extinct volcano," the captain answered me, "a volcano whose interior was invaded by the sea after some convulsion in the earth. While you were sleeping, professor, the Nautilus entered this lagoon through a natural channel that opens ten meters below the surface of the ocean. This is our home port, secure, convenient, secret, and sheltered against winds from any direction!

Along the coasts of your continents or islands, show me any offsh.o.r.e mooring that can equal this safe refuge for withstanding the fury of hurricanes."

"Indeed," I replied, "here you're in perfect safety, Captain Nemo. Who could reach you in the heart of a volcano?

But don't I see an opening at its summit?"

"Yes, its crater, a crater formerly filled with lava, steam, and flames, but which now lets in this life-giving air we're breathing."

"But which volcanic mountain is this?" I asked.

"It's one of the many islets with which this sea is strewn.

For ships a mere reef, for us an immense cavern. I discovered it by chance, and chance served me well."

"But couldn't someone enter through the mouth of its crater?"

"No more than I could exit through it. You can climb about 100 feet up the inner base of this mountain, but then the walls overhang, they lean too far in to be scaled."

"I can see, captain, that nature is your obedient servant, any time or any place. You're safe on this lake, and n.o.body else can visit its waters. But what's the purpose of this refuge?

The Nautilus doesn't need a harbor."

"No, professor, but it needs electricity to run, batteries to generate its electricity, sodium to feed its batteries, coal to make its sodium, and coalfields from which to dig its coal.

Now then, right at this spot the sea covers entire forests that sank underwater in prehistoric times; today, turned to stone, transformed into carbon fuel, they offer me inexhaustible coal mines."

"So, captain, your men practice the trade of miners here?"

"Precisely. These mines extend under the waves like the coalfields at Newcastle. Here, dressed in diving suits, pick and mattock in hand, my men go out and dig this carbon fuel for which I don't need a single mine on land. When I burn this combustible to produce sodium, the smoke escaping from the mountain's crater gives it the appearance of a still-active volcano."

"And will we see your companions at work?"

"No, at least not this time, because I'm eager to continue our underwater tour of the world. Accordingly, I'll rest content with drawing on my reserve stock of sodium. We'll stay here long enough to load it on board, in other words, a single workday, then we'll resume our voyage. So, Professor Aronnax, if you'd like to explore this cavern and circle its lagoon, seize the day."

I thanked the captain and went to look for my two companions, who hadn't yet left their cabin. I invited them to follow me, not telling them where we were.

They climbed onto the platform. Conseil, whom nothing could startle, saw it as a perfectly natural thing to fall asleep under the waves and wake up under a mountain. But Ned Land had no idea in his head other than to see if this cavern offered some way out.

After breakfast near ten o'clock, we went down onto the embankment.

"So here we are, back on sh.o.r.e," Conseil said.

"I'd hardly call this sh.o.r.e," the Canadian replied. "And besides, we aren't on it but under it."

A sandy beach unfolded before us, measuring 500 feet at its widest point between the waters of the lake and the foot of the mountain's walls.

Via this strand you could easily circle the lake. But the base of these high walls consisted of broken soil over which there lay picturesque piles of volcanic blocks and enormous pumice stones.

All these crumbling ma.s.ses were covered with an enamel polished by the action of underground fires, and they glistened under the stream of electric light from our beacon. Stirred up by our footsteps, the mica-rich dust on this beach flew into the air like a cloud of sparks.

The ground rose appreciably as it moved away from the sand flats by the waves, and we soon arrived at some long, winding gradients, genuinely steep paths that allowed us to climb little by little; but we had to tread cautiously in the midst of pudding stones that weren't cemented together, and our feet kept skidding on gla.s.sy trachyte, made of feldspar and quartz crystals.

The volcanic nature of this enormous pit was apparent all around us.

I ventured to comment on it to my companions.

"Can you picture," I asked them, "what this funnel must have been like when it was filled with boiling lava, and the level of that incandescent liquid rose right to the mountain's mouth, like cast iron up the insides of a furnace?"

"I can picture it perfectly," Conseil replied. "But will master tell me why this huge smelter suspended operations, and how it is that an oven was replaced by the tranquil waters of a lake?"

"In all likelihood, Conseil, because some convulsion created an opening below the surface of the ocean, the opening that serves as a pa.s.sageway for the Nautilus. Then the waters of the Atlantic rushed inside the mountain. There ensued a dreadful struggle between the elements of fire and water, a struggle ending in King Neptune's favor.

But many centuries have pa.s.sed since then, and this submerged volcano has changed into a peaceful cavern."

"That's fine," Ned Land answered. "I accept the explanation, but in our personal interests, I'm sorry this opening the professor mentions wasn't made above sea level."

"But Ned my friend," Conseil answered, "if it weren't an underwater pa.s.sageway, the Nautilus couldn't enter it!"

"And I might add, Mr. Land," I said, "that the waters wouldn't have rushed under the mountain, and the volcano would still be a volcano.

So you have nothing to be sorry about."

Our climb continued. The gradients got steeper and narrower.

Sometimes they were cut across by deep pits that had to be cleared.

Ma.s.ses of overhanging rock had to be gotten around. You slid on your knees, you crept on your belly. But helped by the Canadian's strength and Conseil's dexterity, we overcame every obstacle.

At an elevation of about thirty meters, the nature of the terrain changed without becoming any easier. Pudding stones and trachyte gave way to black basaltic rock: here, lying in slabs all swollen with blisters; there, shaped like actual prisms and arranged into a series of columns that supported the springings of this immense vault, a wonderful sample of natural architecture. Then, among this basaltic rock, there snaked long, hardened lava flows inlaid with veins of bituminous coal and in places covered by wide carpets of sulfur.

The sunshine coming through the crater had grown stronger, shedding a hazy light over all the volcanic waste forever buried in the heart of this extinct mountain.

But when we had ascended to an elevation of about 250 feet, we were stopped by insurmountable obstacles. The converging inside walls changed into overhangs, and our climb into a circular stroll.

At this topmost level the vegetable kingdom began to challenge the mineral kingdom. Shrubs, and even a few trees, emerged from crevices in the walls. I recognized some spurges that let their caustic, purgative sap trickle out. There were heliotropes, very remiss at living up to their sun-worshipping reputations since no sunlight ever reached them; their cl.u.s.ters of flowers drooped sadly, their colors and scents were faded. Here and there chrysanthemums sprouted timidly at the feet of aloes with long, sad, sickly leaves.

But between these lava flows I spotted little violets that still gave off a subtle fragrance, and I confess that I inhaled it with delight.

The soul of a flower is its scent, and those splendid water plants, flowers of the sea, have no souls!

We had arrived at the foot of a st.u.r.dy clump of dragon trees, which were splitting the rocks with exertions of their muscular roots, when Ned Land exclaimed:
