Part 32

The panels opened, and I saw the sea entirely white all round. A sulphurous smoke was curling amid the waves, which boiled like water in a copper. I placed my hand on one of the panes of glass, but the heat was so great that I quickly took it off again.

“Where are we?” I asked.

“Near the Island of Santorin, sir,” replied the Captain. “I wished to give you a sight of the curious spectacle of a submarine eruption.”

“I thought,” said I, “that the formation of these new islands was ended.”

“Nothing is ever ended in the volcanic parts of the sea,” replied Captain Nemo; “and the globe is always being worked by subterranean fires. Already, in the nineteenth year of our era, according to Cassiodorus and Pliny, a new island, Theia (the divine), appeared in the very place where these islets have recently been formed. Then they sank under the waves, to rise again in the year 69, when they again subsided. Since that time to our days the Plutonian work has been suspended. But on the 3rd of February, 1866, a new island, which they named George Island, emerged from the midst of the sulphurous vapour near Nea Kamenni, and settled again the 6th of the same month. Seven days after, the 13th of February, the Island of Aphroessa appeared, leaving between Nea Kamenni and itself a canal ten yards broad. I was in these seas when the phenomenon occurred, and I was able therefore to observe all the different phases. The Island of Aphroessa, of round form, measured 300 feet in diameter, and 30 feet in height. It was composed of black and vitreous lava, mixed with fragments of felspar. And lately, on the 10th of March, a smaller island, called Reka, showed itself near Nea Kamenni, and since then these three have joined together, forming but one and the same island.”

“And the canal in which we are at this moment?” I asked.

“Here it is,” replied Captain Nemo, showing me a map of the Archipelago. “You see, I have marked the new islands.”

I returned to the glass. The _Nautilus_ was no longer moving, the heat was becoming unbearable. The sea, which till now had been white, was red, owing to the presence of salts of iron. In spite of the ship’s being hermetically sealed, an insupportable smell of sulphur filled the saloon, and the brilliancy of the electricity was entirely extinguished by bright scarlet flames. I was in a bath, I was choking, I was broiled.

“We can remain no longer in this boiling water,” said I to the Captain.

“It would not be prudent,” replied the impassive Captain Nemo.

An order was given; the _Nautilus_ tacked about and left the furnace it could not brave with impunity. A quarter of an hour after we were breathing fresh air on the surface. The thought then struck me that, if Ned Land had chosen this part of the sea for our flight, we should never have come alive out of this sea of fire.

The next day, the 16th of February, we left the basin which, between Rhodes and Alexandria, is reckoned about 1,500 fathoms in depth, and the _Nautilus_, passing some distance from Cerigo, quitted the Grecian Archipelago after having doubled Cape Matapan.

CHAPTER VII THE MEDITERRANEAN IN FORTY-EIGHT HOURS

The Mediterranean, the blue sea par excellence, “the great sea” of the Hebrews, “the sea” of the Greeks, the “mare nostrum” of the Romans, bordered by orange-trees, aloes, cacti, and sea-pines; embalmed with the perfume of the myrtle, surrounded by rude mountains, saturated with pure and transparent air, but incessantly worked by underground fires; a perfect battlefield in which Neptune and Pluto still dispute the empire of the world!

It is upon these banks, and on these waters, says Michelet, that man is renewed in one of the most powerful climates of the globe. But, beautiful as it was, I could only take a rapid glance at the basin whose superficial area is two million of square yards. Even Captain Nemo’s knowledge was lost to me, for this puzzling person did not appear once during our passage at full speed. I estimated the course which the _Nautilus_ took under the waves of the sea at about six hundred leagues, and it was accomplished in forty-eight hours. Starting on the morning of the 16th of February from the shores of Greece, we had crossed the Straits of Gibraltar by sunrise on the 18th.

It was plain to me that this Mediterranean, enclosed in the midst of those countries which he wished to avoid, was distasteful to Captain Nemo. Those waves and those breezes brought back too many remembrances, if not too many regrets. Here he had no longer that independence and that liberty of gait which he had when in the open seas, and his _Nautilus_ felt itself cramped between the close shores of Africa and Europe.

Our speed was now twenty-five miles an hour. It may be well understood that Ned Land, to his great disgust, was obliged to renounce his intended flight. He could not launch the pinnace, going at the rate of twelve or thirteen yards every second. To quit the _Nautilus_ under such conditions would be as bad as jumping from a train going at full speed—an imprudent thing, to say the least of it. Besides, our vessel only mounted to the surface of the waves at night to renew its stock of air; it was steered entirely by the compass and the log.

I saw no more of the interior of this Mediterranean than a traveller by express train perceives of the landscape which flies before his eyes; that is to say, the distant horizon, and not the nearer objects which pass like a flash of lightning.

We were then passing between Sicily and the coast of Tunis. In the narrow space between Cape Bon and the Straits of Messina the bottom of the sea rose almost suddenly. There was a perfect bank, on which there was not more than nine fathoms of water, whilst on either side the depth was ninety fathoms.

The _Nautilus_ had to manœuvre very carefully so as not to strike against this submarine barrier.

I showed Conseil, on the map of the Mediterranean, the spot occupied by this reef.

“But if you please, sir,” observed Conseil, “it is like a real isthmus joining Europe to Africa.”

“Yes, my boy, it forms a perfect bar to the Straits of Lybia, and the soundings of Smith have proved that in former times the continents between Cape Boco and Cape Furina were joined.”

“I can well believe it,” said Conseil.

“I will add,” I continued, “that a similar barrier exists between Gibraltar and Ceuta, which in geological times formed the entire Mediterranean.”

“What if some volcanic burst should one day raise these two barriers above the waves?”

“It is not probable, Conseil.”

“Well, but allow me to finish, please, sir; if this phenomenon should take place, it will be troublesome for M. Lesseps, who has taken so much pains to pierce the isthmus.”

“I agree with you; but I repeat, Conseil, this phenomenon will never happen. The violence of subterranean force is ever diminishing. Volcanoes, so plentiful in the first days of the world, are being extinguished by degrees; the internal heat is weakened, the temperature of the lower strata of the globe is lowered by a perceptible quantity every century to the detriment of our globe, for its heat is its life.”

“But the sun?”

“The sun is not sufficient, Conseil. Can it give heat to a dead body?”

“Not that I know of.”

“Well, my friend, this earth will one day be that cold corpse; it will become uninhabitable and uninhabited like the moon, which has long since lost all its vital heat.”

“In how many centuries?”

“In some hundreds of thousands of years, my boy.”

“Then,” said Conseil, “we shall have time to finish our journey—that is, if Ned Land does not interfere with it.”

And Conseil, reassured, returned to the study of the bank, which the _Nautilus_ was skirting at a moderate speed.

During the night of the 16th and 17th February we had entered the second Mediterranean basin, the greatest depth of which was 1,450 fathoms. The _Nautilus_, by the action of its screw, slid down the inclined planes and buried itself in the lowest depths of the sea.

On the 18th of February, about three o’clock in the morning, we were at the entrance of the Straits of Gibraltar. There once existed two currents: an upper one, long since recognised, which conveys the waters of the ocean into the basin of the Mediterranean; and a lower counter-current, which reasoning has now shown to exist. Indeed, the volume of water in the Mediterranean, incessantly added to by the waves of the Atlantic and by rivers falling into it, would each year raise the level of this sea, for its evaporation is not sufficient to restore the equilibrium. As it is not so, we must necessarily admit the existence of an under-current, which empties into the basin of the Atlantic through the Straits of Gibraltar the surplus waters of the Mediterranean. A fact indeed; and it was this counter-current by which the _Nautilus_ profited. It advanced rapidly by the narrow pass. For one instant I caught a glimpse of the beautiful ruins of the temple of Hercules, buried in the ground, according to Pliny, and with the low island which supports it; and a few minutes later we were floating on the Atlantic.

CHAPTER VIII VIGO BAY

The Atlantic! a vast sheet of water whose superficial area covers twenty-five millions of square miles, the length of which is nine thousand miles, with a mean breadth of two thousand seven hundred—an ocean whose parallel winding shores embrace an immense circumference, watered by the largest rivers of the world, the St. Lawrence, the Mississippi, the Amazon, the Plata, the Orinoco, the Niger, the Senegal, the Elbe, the Loire, and the Rhine, which carry water from the most civilised, as well as from the most savage, countries! Magnificent field of water, incessantly ploughed by vessels of every nation, sheltered by the flags of every nation, and which terminates in those two terrible points so dreaded by mariners, Cape Horn and the Cape of Tempests.

The _Nautilus_ was piercing the water with its sharp spur, after having accomplished nearly ten thousand leagues in three months and a half, a distance greater than the great circle of the earth. Where were we going now, and what was reserved for the future? The _Nautilus_, leaving the Straits of Gibraltar, had gone far out. It returned to the surface of the waves, and our daily walks on the platform were restored to us.

I mounted at once, accompanied by Ned Land and Conseil. At a distance of about twelve miles, Cape St. Vincent was dimly to be seen, forming the south-western point of the Spanish peninsula. A strong southerly gale was blowing. The sea was swollen and billowy; it made the _Nautilus_ rock violently. It was almost impossible to keep one’s foot on the platform, which the heavy rolls of the sea beat over every instant. So we descended after inhaling some mouthfuls of fresh air.

I returned to my room, Conseil to his cabin; but the Canadian, with a preoccupied air, followed me. Our rapid passage across the Mediterranean had not allowed him to put his project into execution, and he could not help showing his disappointment. When the door of my room was shut, he sat down and looked at me silently.

“Friend Ned,” said I, “I understand you; but you cannot reproach yourself. To have attempted to leave the _Nautilus_ under the circumstances would have been folly.”

Ned Land did not answer; his compressed lips and frowning brow showed with him the violent possession this fixed idea had taken of his mind.

“Let us see,” I continued; “we need not despair yet. We are going up the coast of Portugal again; France and England are not far off, where we can easily find refuge. Now if the _Nautilus_, on leaving the Straits of Gibraltar, had gone to the south, if it had carried us towards regions where there were no continents, I should share your uneasiness. But we know now that Captain Nemo does not fly from civilised seas, and in some days I think you can act with security.”

Ned Land still looked at me fixedly; at length his fixed lips parted, and he said, “It is for to-night.”
