“Besides, Captain,” I added, enthusiastically, “why should we not find the sea open at the South Pole as well as at the North? The frozen poles of the earth do not coincide, either in the southern or in the northern regions; and, until it is proved to the contrary, we may suppose either a continent or an ocean free from ice at these two points of the globe.”

“I think so too, M. Aronnax,” replied Captain Nemo. “I only wish you to observe that, after having made so many objections to my project, you are now crushing me with arguments in its favour!”

The preparations for this audacious attempt now began. The powerful pumps of the Nautilus were working air into the reservoirs and storing it at high pressure. About four o’clock, Captain Nemo announced the closing of the panels on the platform. I threw one last look at the massive iceberg which we were going to cross. The weather was clear, the atmosphere pure enough, the cold very great, being 12° below zero; but, the wind having gone down, this temperature was not so unbearable. About ten men mounted the sides of the Nautilus, armed with pickaxes to break the ice around the vessel, which was soon free. The operation was quickly performed, for the fresh ice was still very thin. We all went below. The usual reservoirs were filled with the newly-liberated water, and the Nautilus soon descended. I had taken my place with Conseil in the saloon; through the open window we could see the lower beds of the Southern Ocean. The thermometer went up, the needle of the compass deviated on the dial. At about 900 feet, as Captain Nemo had foreseen, we were floating beneath beneath the undulating bottom of the iceberg. But the Nautilus went lower still—it went to the depth of four hundred fathoms. The temperature of the water at the surface showed twelve degrees, it was now only ten; we had gained two. I need not say the temperature of the Nautilus was raised by its heating apparatus to a much higher degree; every manoeuvre was accomplished with wonderful precision.

“We shall pass it, if you please, sir,” said Conseil.

“I believe we shall,” I said, in a tone of firm conviction.

In this open sea, the Nautilus had taken its course direct to the pole, without leaving the fifty-second meridian. From 67° 30’ to 90°, twenty-two degrees and a half of latitude remained to travel; that is, about five hundred leagues. The Nautilus kept up a mean speed of twenty-six miles an hour— the speed of an express train. If that was kept up, in forty hours we should reach the pole.

For a part of the night the novelty of the situation kept us at the window. The sea was lit with the electric lantern; but it was deserted; fishes did not sojourn in these imprisoned waters; they only found there a passage to take them from the Antarctic Ocean to the open polar sea. Our pace was rapid; we could feel it by the quivering of the long steel body. About two in the morning I took some hours’ repose, and Conseil did the same. In crossing the waist I did not meet Captain Nemo: I supposed him to be in the pilot’s cage. The next morning, the 19th of March, I took my post once more in the saloon. The electric log told me that the speed of the Nautilus had been slackened. It was then going towards the surface; but prudently emptying its reservoirs very slowly. My heart beat fast. Were we going to emerge and regain the open polar atmosphere? No! A shock told me that the Nautilus had struck the bottom of the iceberg, still very thick, judging from the deadened sound. We had in deed “struck,” to use a sea expression, but in an inverse sense, and at a thousand feet deep. This would give three thousand feet of ice above us; one thousand being above the water-mark. The iceberg was then higher than at its borders—not a very reassuring fact. Several times that day the Nautilus tried again, and every time it struck the wall which lay like a ceiling above it. Sometimes it met with but 900 yards, only 200 of which rose above the surface. It was twice the height it was when the Nautilus had gone under the waves. I carefully noted the different depths, and thus obtained a submarine profile of the chain as it was developed under the water. That night no change had taken place in our situation. Still ice between four and five hundred yards in depth! It was evidently diminishing, but, still, what a thickness between us and the surface of the ocean! It was then eight. According to the daily custom on board the Nautilus, its air should have been renewed four hours ago; but I did not suffer much, although Captain Nemo had not yet made any demand upon his reserve of oxygen. My sleep was painful that night; hope and fear besieged me by turns: I rose several times. The groping of the Nautilus continued. About three in the morning, I noticed that the lower surface of the iceberg was only about fifty feet deep. One hundred and fifty feet now separated us from the surface of the waters. The iceberg was by degrees becoming an ice-field, the mountain a plain. My eyes never left the manometer. We were still rising diagonally to the surface, which sparkled under the electric rays. The iceberg was stretching both above and beneath into lengthening slopes; mile after mile it was getting thinner. At length, at six in the morning of that memorable day, the 19th of March, the door of the saloon opened, and Captain Nemo appeared.

“Where and when?”

“Where I do not know—when I cannot say; or, rather, I suppose it will end when these seas have nothing more to teach us.”

“Then what do you hope for?” demanded the Canadian.

“That circumstances may occur as well six months hence as now by which we may and ought to profit.”

“Oh!” said Ned Land, “and where shall we be in six months, if you please, Sir Naturalist?”

“Perhaps in China; you know the Nautilus is a rapid traveller. It goes through water as swallows through the air, or as an express on the land. It does not fear frequented seas; who can say that it may not beat the coasts of France, England, or America, on which flight may be attempted as advantageously as here.”

“M. Aronnax,” replied the Canadian, “your arguments are rotten at the foundation. You speak in the future, ‘We shall be there! we shall be here!’ I speak in the present, ‘We are here, and we must profit by it.’”

Ned Land’s logic pressed me hard, and I felt myself beaten on that ground. I knew not what argument would now tell in my favour.

“Sir,” continued Ned, “let us suppose an impossibility: if Captain Nemo should this day offer you your liberty; would you accept it?”

“I do not know,” I answered.

“And if,” he added, “the offer made you this day was never to be renewed, would you accept it?”

“Friend Ned, this is my answer. Your reasoning is against me. We must not rely on Captain Nemo’s good-will. Common prudence forbids him to set us at liberty. On the other side, prudence bids us profit by the first opportunity to leave the Nautilus.”

“Well, M. Aronnax, that is wisely said.”

“Only one observation—just one. The occasion must be serious, and our first attempt must succeed; if it fails, we shall never find another, and Captain Nemo will never forgive us.”

“All that is true,” replied the Canadian. “But your observation applies equally to all attempts at flight, whether in two years’ time, or in two days’. But the question is still this: If a favourable opportunity presents itself, it must be seized.”

“Agreed! And now, Ned, will you tell me what you mean by a favourable opportunity?”

“It will be that which, on a dark night, will bring the Nautilus a short distance from some European coast.”

“And you will try and save yourself by swimming?”

“Yes, if we were near enough to the bank, and if the vessel was floating at the time. Not if the bank was far away, and the boat was under the water.”

“And in that case?”

“In that case, I should seek to make myself master of the pinnace. I know how it is worked. We must get inside, and the bolts once drawn, we shall come to the surface of the water, without even the pilot, who is in the bows, perceiving our flight.”
