"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 quant.i.ty 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, rea.s.sured, 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 crew, 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 pa.s.s. 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 sh.o.r.es embrace an immense circ.u.mference, 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 pa.s.sage 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 circ.u.mstances 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."

I drew myself up suddenly. I was, I admit, little prepared for this communication. I wanted to answer the Canadian, but words would not come.

"We agreed to wait for an opportunity," continued Ned Land, "and the opportunity has arrived. This night we shall be but a few miles from the Spanish coast. It is cloudy. The wind blows freely. I have your word, M. Aronnax, and I rely upon you."

As I was silent, the Canadian approached me.

"To-night, at nine o'clock," said he. "I have warned Conseil. At that moment Captain Nemo will be shut up in his room, probably in bed.

Neither the engineers nor the ship's crew can see us. Conseil and I will gain the central staircase, and you, M. Aronnax, will remain in the library, two steps from us, waiting my signal. The oars, the mast, and the sail are in the canoe. I have even succeeded in getting some provisions. I have procured an English wrench, to unfasten the bolts which attach it to the sh.e.l.l of the Nautilus. So all is ready, till to-night."

"The sea is bad."

"That I allow," replied the Canadian; "but we must risk that. Liberty is worth paying for; besides, the boat is strong, and a few miles with a fair wind to carry us is no great thing. Who knows but by to-morrow we may be a hundred leagues away? Let circ.u.mstances only favour us, and by ten or eleven o'clock we shall have landed on some spot of terra firma, alive or dead. But adieu now till to-night."

With these words the Canadian withdrew, leaving me almost dumb. I had imagined that, the chance gone, I should have time to reflect and discuss the matter. My obstinate companion had given me no time; and, after all, what could I have said to him? Ned Land was perfectly right. There was almost the opportunity to profit by. Could I retract my word, and take upon myself the responsibility of compromising the future of my companions? To-morrow Captain Nemo might take us far from all land.

At that moment a rather loud hissing noise told me that the reservoirs were filling, and that the Nautilus was sinking under the waves of the Atlantic.

A sad day I pa.s.sed, between the desire of regaining my liberty of action and of abandoning the wonderful Nautilus, and leaving my submarine studies incomplete.

What dreadful hours I pa.s.sed thus! Sometimes seeing myself and companions safely landed, sometimes wishing, in spite of my reason, that some unforeseen circ.u.mstance, would prevent the realisation of Ned Land's project.

Twice I went to the saloon. I wished to consult the compa.s.s. I wished to see if the direction the Nautilus was taking was bringing us nearer or taking us farther from the coast. But no; the Nautilus kept in Portuguese waters.

I must therefore take my part and prepare for flight. My luggage was not heavy; my notes, nothing more.

As to Captain Nemo, I asked myself what he would think of our escape; what trouble, what wrong it might cause him and what he might do in case of its discovery or failure. Certainly I had no cause to complain of him; on the contrary, never was hospitality freer than his. In leaving him I could not be taxed with ingrat.i.tude. No oath bound us to him. It was on the strength of circ.u.mstances he relied, and not upon our word, to fix us for ever.

I had not seen the Captain since our visit to the Island of Santorin.

Would chance bring me to his presence before our departure? I wished it, and I feared it at the same time. I listened if I could hear him walking the room contiguous to mine. No sound reached my ear. I felt an unbearable uneasiness. This day of waiting seemed eternal. Hours struck too slowly to keep pace with my impatience.

My dinner was served in my room as usual. I ate but little; I was too preoccupied. I left the table at seven o'clock. A hundred and twenty minutes (I counted them) still separated me from the moment in which I was to join Ned Land. My agitation redoubled. My pulse beat violently. I could not remain quiet. I went and came, hoping to calm my troubled spirit by constant movement. The idea of failure in our bold enterprise was the least painful of my anxieties; but the thought of seeing our project discovered before leaving the Nautilus, of being brought before Captain Nemo, irritated, or (what was worse) saddened, at my desertion, made my heart beat.

I wanted to see the saloon for the last time. I descended the stairs and arrived in the museum, where I had pa.s.sed so many useful and agreeable hours. I looked at all its riches, all its treasures, like a man on the eve of an eternal exile, who was leaving never to return.

These wonders of Nature, these masterpieces of art, amongst which for so many days my life had been concentrated, I was going to abandon them for ever! I should like to have taken a last look through the windows of the saloon into the waters of the Atlantic: but the panels were hermetically closed, and a cloak of steel separated me from that ocean which I had not yet explored.

In pa.s.sing through the saloon, I came near the door let into the angle which opened into the Captain's room. To my great surprise, this door was ajar. I drew back involuntarily. If Captain Nemo should be in his room, he could see me. But, hearing no sound, I drew nearer. The room was deserted. I pushed open the door and took some steps forward.

Still the same monklike severity of aspect.

Suddenly the clock struck eight. The first beat of the hammer on the bell awoke me from my dreams. I trembled as if an invisible eye had plunged into my most secret thoughts, and I hurried from the room.

There my eye fell upon the compa.s.s. Our course was still north. The log indicated moderate speed, the manometer a depth of about sixty feet.

I returned to my room, clothed myself warmly--sea boots, an otterskin cap, a great coat of byssus, lined with sealskin; I was ready, I was waiting. The vibration of the screw alone broke the deep silence which reigned on board. I listened attentively. Would no loud voice suddenly inform me that Ned Land had been surprised in his projected flight. A mortal dread hung over me, and I vainly tried to regain my accustomed coolness.

At a few minutes to nine, I put my ear to the Captain's door. No noise. I left my room and returned to the saloon, which was half in obscurity, but deserted.
