1On this day for several hours I used my pickaxe vigorously. The work kept me up. Besides, to work was to quit the
2Nautilus, and breathe directly the pure air drawn from the reservoirs, and supplied by our apparatus, and to quit the
3impoverished and vitiated atmosphere. Towards evening the trench was dug one yard deeper. When I returned on board, I
4was nearly suffocated by the carbonic acid with which the air was filled--ah! if we had only the chemical means to drive
5away this deleterious gas. We had plenty of oxygen; all this water contained a considerable quantity, and by dissolving
6it with our powerful piles, it would restore the vivifying fluid. I had thought well over it; but of what good was that,
7since the carbonic acid produced by our respiration had invaded every part of the vessel? To absorb it, it was necessary
8to fill some jars with caustic potash, and to shake them incessantly. Now this substance was wanting on board, and
9nothing could replace it. On that evening, Captain Nemo ought to open the taps of his reservoirs, and let some pure air
10into the interior of the Nautilus; without this precaution we could not get rid of the sense of suffocation. The next
11day, March 26th, I resumed my miner's work in beginning the fifth yard. The side walls and the lower surface of the
12iceberg thickened visibly. It was evident that they would meet before the Nautilus was able to disengage itself. Despair
13seized me for an instant; my pickaxe nearly fell from my hands. What was the good of digging if I must be suffocated,
14crushed by the water that was turning into stone?--a punishment that the ferocity of the savages even would not have
15invented! Just then Captain Nemo passed near me. I touched his hand and showed him the walls of our prison. The wall to
16port had advanced to at least four yards from the hull of the Nautilus. The Captain understood me, and signed me to
17follow him. We went on board. I took off my cork-jacket and accompanied him into the drawing-room. "M. Aronnax, we must
18attempt some desperate means, or we shall be sealed up in this solidified water as in cement." "Yes; but what is to be
19done?" "Ah! if my Nautilus were strong enough to bear this pressure without being crushed!" "Well?" I asked, not
20catching the Captain's idea. "Do you not understand," he replied, "that this congelation of water will help us? Do you
21not see that by its solidification, it would burst through this field of ice that imprisons us, as, when it freezes, it
22bursts the hardest stones? Do you not perceive that it would be an agent of safety instead of destruction?" "Yes,
23Captain, perhaps. But, whatever resistance to crushing the Nautilus possesses, it could not support this terrible
24pressure, and would be flattened like an iron plate." "I know it, sir. Therefore we must not reckon on the aid of
25nature, but on our own exertions. We must stop this solidification. Not only will the side walls be pressed together;
26but there is not ten feet of water before or behind the Nautilus. The congelation gains on us on all sides." "How long
27will the air in the reservoirs last for us to breathe on board?" The Captain looked in my face. "After to-morrow they
28will be empty!" A cold sweat came over me. However, ought I to have been astonished at the answer? On March 22, the
29Nautilus was in the open polar seas. We were at 26°. For five days we had lived on the reserve on board. And what was
30left of the respirable air must be kept for the workers. Even now, as I write, my recollection is still so vivid that an
31involuntary terror seizes me and my lungs seem to be without air. Meanwhile, Captain Nemo reflected silently, and
32evidently an idea had struck him; but he seemed to reject it. At last, these words escaped his lips: "Boiling water!" he
33muttered. "Boiling water?" I cried. "Yes, sir. We are enclosed in a space that is relatively confined. Would not jets of
34boiling water, constantly injected by the pumps, raise the temperature in this part and stay the congelation?" "Let us
35try it," I said resolutely. "Let us try it, Professor." The thermometer then stood at 7° outside. Captain Nemo took me
36to the galleys, where the vast distillatory machines stood that furnished the drinkable water by evaporation. They
37filled these with water, and all the electric heat from the piles was thrown through the worms bathed in the liquid. In
38a few minutes this water reached 100°. It was directed towards the pumps, while fresh water replaced it in proportion.
39The heat developed by the troughs was such that cold water, drawn up from the sea after only having gone through the
40machines, came boiling into the body of the pump. The injection was begun, and three hours after the thermometer marked
416° below zero outside. One degree was gained. Two hours later the thermometer only marked 4°. "We shall succeed," I said
42to the Captain, after having anxiously watched the result of the operation. "I think," he answered, "that we shall not
43be crushed. We have no more suffocation to fear." During the night the temperature of the water rose to 1° below zero.
44The injections could not carry it to a higher point. But, as the congelation of the sea-water produces at least 2°, I
45was at least reassured against the dangers of solidification. The next day, March 27th, six yards of ice had been
46cleared, twelve feet only remaining to be cleared away. There was yet forty-eight hours' work. The air could not be
47renewed in the interior of the Nautilus. And this day would make it worse. An intolerable weight oppressed me. Towards
48three o'clock in the evening this feeling rose to a violent degree. Yawns dislocated my jaws. My lungs panted as they
49inhaled this burning fluid, which became rarefied more and more. A moral torpor took hold of me. I was powerless, almost
50unconscious. My brave Conseil, though exhibiting the same symptoms and suffering in the same manner, never left me. He
51took my hand and encouraged me, and I heard him murmur, "Oh! if I could only not breathe, so as to leave more air for my
52master!" Tears came into my eyes on hearing him speak thus. If our situation to all was intolerable in the interior,
53with what haste and gladness would we put on our cork-jackets to work in our turn! Pickaxes sounded on the frozen
54ice-beds. Our arms ached, the skin was torn off our hands. But what were these fatigues, what did the wounds matter?
55Vital air came to the lungs! We breathed! we breathed! All this time no one prolonged his voluntary task beyond the
56prescribed time. His task accomplished, each one handed in turn to his panting companions the apparatus that supplied
57him with life. Captain Nemo set the example, and submitted first to this severe discipline. When the time came, he gave
58up his apparatus to another and returned to the vitiated air on board, calm, unflinching, unmurmuring. On that day the
59ordinary work was accomplished with unusual vigour. Only two yards remained to be raised from the surface. Two yards
60only separated us from the open sea. But the reservoirs were nearly emptied of air. The little that remained ought to be
61kept for the workers; not a particle for the Nautilus. When I went back on board, I was half suffocated. What a night! I
62know not how to describe it. The next day my breathing was oppressed. Dizziness accompanied the pain in my head and made
63me like a drunken man. My companions showed the same symptoms. Some of the crew had rattling in the throat. On that day,
64the sixth of our imprisonment, Captain Nemo, finding the pickaxes work too slowly, resolved to crush the ice-bed that
65still separated us from the liquid sheet. This man's coolness and energy never forsook him. He subdued his physical
66pains by moral force. By his orders the vessel was lightened, that is to say, raised from the ice-bed by a change of
67specific gravity. When it floated they towed it so as to bring it above the immense trench made on the level of the
68water-line. Then, filling his reservoirs of water, he descended and shut himself up in the hole.
