From 67 degrees 30' to 90 degrees, twenty-two and a half degrees of latitude were left to cross, in other words, slightly more than 500 leagues. The Nautilus adopted an average speed of twenty-six miles per hour, the speed of an express train. If it kept up this pace, forty hours would do it for reaching the pole.
For part of the night, the novelty of our circumstances kept Conseil and me at the lounge window. The sea was lit by our beacon's electric rays. But the depths were deserted. Fish didn't linger in these imprisoned waters. Here they found merely a passageway for going from the Antarctic Ocean to open sea at the pole. Our progress was swift. You could feel it in the vibrations of the long steel hull.
Near two o'clock in the morning, I went to snatch a few hours of sleep. Conseil did likewise. I didn't encounter Captain Nemo while going down the gangways. I assumed that he was keeping to the pilothouse.
The next day, March 19, at five o'clock in the morning, I was back at my post in the lounge. The electric log indicated that the Nautilus had reduced speed. By then it was rising to the surface, but cautiously, while slowly emptying its ballast tanks.
My heart was pounding. Would we emerge into the open and find the polar air again?
No. A jolt told me that the Nautilus had bumped the underbelly of the Ice Bank, still quite thick to judge from the hollowness of the accompanying noise. Indeed, we had "struck bottom," to use nautical terminology, but in the opposite direction and at a depth of 3,000 feet. That gave us 4,000 feet of ice overhead, of which 1,000 feet emerged above water. So the Ice Bank was higher here than we had found it on the outskirts. A circumstance less than encouraging.
Several times that day, the Nautilus repeated the same experiment and always it bumped against this surface that formed a ceiling above it. At certain moments the ship encountered ice at a depth of 900 meters, denoting a thickness of 1,200 meters, of which 300 meters rose above the level of the ocean. This height had tripled since the moment the Nautilus had dived beneath the waves.
I meticulously noted these different depths, obtaining the underwater profile of this upside-down mountain chain that stretched beneath the sea.
By evening there was still no improvement in our situation. The ice stayed between 400 and 500 meters deep. It was obviously shrinking, but what a barrier still lay between us and the surface of the ocean!
By then it was eight o'clock. The air inside the Nautilus should have been renewed four hours earlier, following daily practice on board. But I didn't suffer very much, although Captain Nemo hadn't yet made demands on the supplementary oxygen in his air tanks.
That night my sleep was fitful. Hope and fear besieged me by turns. I got up several times. The Nautilus continued groping. Near three o'clock in the morning, I observed that we encountered the Ice Bank's underbelly at a depth of only fifty meters. So only 150 feet separated us from the surface of the water. Little by little the Ice Bank was turning into an ice field again. The mountains were changing back into plains.
My eyes didn't leave the pressure gauge. We kept rising on a diagonal, going along this shiny surface that sparkled beneath our electric rays. Above and below, the Ice Bank was subsiding in long gradients. Mile after mile it was growing thinner.
Finally, at six o'clock in the morning on that memorable day of March 19, the lounge door opened. Captain Nemo appeared.
"Open sea!" he told me.
CHAPTER 14
The South Pole
I RUSHED UP onto the platform. Yes, open sea! Barely a few sparse floes, some moving
icebergs; a sea stretching into the distance; hosts of birds in the air and myriads of fish under the waters, which varied from intense blue to olive green depending on the depth. The thermometer marked 3 degrees centigrade. It was as if a comparative springtime had been locked up behind that Ice Bank, whose distant masses were outlined on the northern horizon.
