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 foremostin 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 areindescribable. The next day I was short-winded. Headaches and staggering fits of dizziness made me reel likea 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.
