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.

We waited, we listened, we forgot our sufferings, we hoped once more. We had staked our salvation on this one last gamble.

Despite the buzzing in my head, I soon could hear vibrations under the Nautilus's hull. We tilted. The ice cracked with an odd ripping sound, like paper tearing, and the Nautilus began settling downward.

"We're going through!" Conseil muttered in my ear.

I couldn't answer him. I clutched his hand. I squeezed it in an involuntary convulsion.

All at once, carried away by its frightful excess load, the Nautilus sank into the waters like a cannonball, in other words, dropping as if in a vacuum!

Our full electric power was then put on the pumps, which instantly began to expel water from the ballast tanks. After a few minutes we had checked our fall. The pressure gauge soon indicated an ascending movement. Brought to full speed, the propeller made the sheet-iron hull tremble down to its rivets, and we sped northward.

But how long would it take to navigate under the Ice Bank to the open sea? Another day? I would be dead first!

Half lying on a couch in the library, I was suffocating. My face was purple, my lips blue, my faculties in abeyance. I could no longer see or hear. I had lost all sense of time. My muscles had no power to contract.

I'm unable to estimate the hours that passed in this way. But I was aware that my death throes had begun. I realized that I was about to die . . .

Suddenly I regained consciousness. A few whiffs of air had entered my lungs. Had we risen to the surface of the waves? Had we cleared the Ice Bank?

No! Ned and Conseil, my two gallant friends, were sacrificing themselves to save me. A few atoms of air were still left in the depths of one Rouquayrol device. Instead of breathing it themselves, they had saved it for me, and while they were suffocating, they poured life into me drop by drop! I tried to push the device away. They held my hands, and for a few moments I could breathe luxuriously.

My eyes flew toward the clock. It was eleven in the morning. It had to be March 28. The Nautilus was traveling at the frightful speed of forty miles per hour. It was writhing in the waters.

Where was Captain Nemo? Had he perished? Had his companions died with him?

Just then the pressure gauge indicated we were no more than twenty feet from the surface. Separating us from the open air was a mere tract of ice. Could we break through it?

Perhaps! In any event the Nautilus was going to try. In fact, I could feel it assuming an oblique position, lowering its stern and raising its spur. The admission of additional water was enough to shift its balance. Then, driven by its powerful propeller, it attacked this ice field from below like a fearsome battering ram. It split the barrier little by little, backing up, then putting on full speed against the punctured tract of ice; and finally, carried away by its supreme momentum, it lunged through and onto this frozen surface, crushing the ice beneath its weight.

The hatches were opened--or torn off, if you prefer--and waves of clean air were admitted into every part of the Nautilus.
