The steaming water was injected into the icy water outside, and after three hours had passed, the thermometer gave the exterior temperature as -6 degrees centigrade. That was one degree gained. Two hours later the thermometer gave only -4 degrees.

After I monitored the operation's progress, double-checking it with many inspections, I told the captain, "It's working."

"I think so," he answered me. "We've escaped being crushed. Now we have only asphyxiation to fear."

During the night the water temperature rose to -1 degrees centigrade. The injections couldn't get it to go a single degree higher. But since salt water freezes only at -2 degrees, I was finally assured that there was no danger of it solidifying.

By the next day, March 27, six meters of ice had been torn from the socket. Only four meters were left to be removed. That still meant forty-eight hours of work. The air couldn't be renewed in the Nautilus's interior. Accordingly, that day it kept getting worse.

An unbearable heaviness weighed me down. Near three o'clock in the afternoon, this agonizing sensation affected me to an intense degree. Yawns dislocated my jaws. My lungs were gasping in their quest for that enkindling elastic fluid required for breathing, now growing scarcer and scarcer. My mind was in a daze. I lay outstretched, strength gone, nearly unconscious. My gallant Conseil felt the same symptoms, suffered the same sufferings, yet never left my side. He held my hand, he kept encouraging me, and I even heard him mutter:

"Oh, if only I didn't have to breathe, to leave more air for master!"

It brought tears to my eyes to hear him say these words.

Since conditions inside were universally unbearable, how eagerly, how happily, we put on our diving suits to take our turns working! Picks rang out on that bed of ice. Arms grew weary, hands were rubbed raw, but who cared about exhaustion, what difference were wounds? Life-sustaining air reached our lungs! We could breathe! We could breathe!

And yet nobody prolonged his underwater work beyond the time allotted him. His shift over, each man surrendered to a gasping companion the air tank that would revive him. Captain Nemo set the example and was foremost in submitting to this strict discipline. When his time was up, he yielded his equipment to another and reentered the foul air on board, always calm, unflinching, and uncomplaining.

That day the usual work was accomplished with even greater energy. Over the whole surface area, only two meters were left to be removed. Only two meters separated us from the open sea. But the ship's air tanks were nearly empty. The little air that remained had to be saved for the workmen. Not an atom for the Nautilus!

When I returned on board, I felt half suffocated. What a night! I'm unable to depict it. Such sufferings are indescribable. The next day I was short-winded. Headaches and staggering fits of dizziness made me reel like a drunk. My companions were experiencing the same symptoms. Some crewmen were at their last gasp.

That day, the sixth of our imprisonment, Captain Nemo concluded that picks and mattocks were too slow to deal with the ice layer still separating us from open water--and he decided to crush this layer. The man had kept his energy and composure. He had subdued physical pain with moral strength. He could still think, plan, and act.

At his orders the craft was eased off, in other words, it was raised from its icy bed by a change in its specific gravity. When it was afloat, the crew towed it, leading it right above the immense trench outlined to match the ship's waterline. Next the ballast tanks filled with water, the boat sank, and was fitted into its socket.

Just then the whole crew returned on board, and the double outside door was closed. By this point the Nautilus was resting on a bed of ice only one meter thick and drilled by bores in a thousand places.

The stopcocks of the ballast tanks were then opened wide, and 100 cubic meters of water rushed in, increasing the Nautilus's weight by 100,000 kilograms.
