Then the panels in the lounge closed. We kept our hands over our eyes, which were utterly saturated with those concentric gleams that swirl before the retina when sunlight strikes it too intensely. It took some time to calm our troubled vision.

Finally we lowered our hands.

"Ye G.o.ds, I never would have believed it," Conseil said.

"And I still don"t believe it!" the Canadian shot back.

"When we return to sh.o.r.e, jaded from all these natural wonders," Conseil added, "think how we"ll look down on those pitiful land ma.s.ses, those puny works of man! No, the civilized world won"t be good enough for us!"

Such words from the lips of this emotionless Flemish boy showed that our enthusiasm was near the boiling point. But the Canadian didn"t fail to throw his dram of cold water over us.

"The civilized world!" he said, shaking his head. "Don"t worry, Conseil my friend, we"re never going back to that world!"

By this point it was five o"clock in the morning. Just then there was a collision in the Nautilus"s bow. I realized that its spur had just b.u.mped a block of ice. It must have been a faulty maneuver because this underwater tunnel was obstructed by such blocks and didn"t make for easy navigating. So I had a.s.sumed that Captain Nemo, in adjusting his course, would go around each obstacle or would hug the walls and follow the windings of the tunnel. In either case our forward motion wouldn"t receive an absolute check. Nevertheless, contrary to my expectations, the Nautilus definitely began to move backward.

"We"re going astern?" Conseil said.

"Yes," I replied. "Apparently the tunnel has no way out at this end."

"And so ... ?"

"So," I said, "our maneuvers are quite simple. We"ll return in our tracks and go out the southern opening. That"s all."

As I spoke, I tried to sound more confident than I really felt. Meanwhile the Nautilus accelerated its backward movement, and running with propeller in reverse, it swept us along at great speed.

"This"ll mean a delay," Ned said.

"What are a few hours more or less, so long as we get out."

"Yes," Ned Land repeated, "so long as we get out!"

I strolled for a little while from the lounge into the library. My companions kept their seats and didn"t move. Soon I threw myself down on a couch and picked up a book, which my eyes skimmed mechanically.

A quarter of an hour later, Conseil approached me, saying: "Is it deeply fascinating, this volume master is reading?"

"Tremendously fascinating," I replied.

"I believe it. Master is reading his own book!"

"My own book?"

Indeed, my hands were holding my own work on the great ocean depths. I hadn"t even suspected. I closed the book and resumed my strolling. Ned and Conseil stood up to leave.

"Stay here, my friends," I said, stopping them. "Let"s stay together until we"re out of this blind alley."

"As master wishes," Conseil replied.

The hours pa.s.sed. I often studied the instruments hanging on the lounge wall. The pressure gauge indicated that the Nautilus stayed at a constant depth of 300 meters, the compa.s.s that it kept heading south, the log that it was traveling at a speed of twenty miles per hour, an excessive speed in such a cramped area. But Captain Nemo knew that by this point there was no such thing as too fast, since minutes were now worth centuries.

At 8:25 a second collision took place. This time astern. I grew pale. My companions came over. I clutched Conseil"s hand. Our eyes questioned each other, and more directly than if our thoughts had been translated into words.

Just then the captain entered the lounge. I went to him.

"Our path is barred to the south?" I asked him.

"Yes, sir. When it overturned, that iceberg closed off every exit."

"We"re boxed in?"

"Yes."

CHAPTER 16.

Shortage of Air.

CONSEQUENTLY, above, below, and around the Nautilus, there were impenetrable frozen walls. We were the Ice Bank"s prisoners! The Canadian banged a table with his fearsome fist. Conseil kept still. I stared at the captain. His face had resumed its usual emotionlessness. He crossed his arms. He pondered. The Nautilus did not stir.

The captain then broke into speech: "Gentlemen," he said in a calm voice, "there are two ways of dying under the conditions in which we"re placed."

This inexplicable individual acted like a mathematics professor working out a problem for his pupils.

"The first way," he went on, "is death by crushing. The second is death by asphyxiation. I don"t mention the possibility of death by starvation because the Nautilus"s provisions will certainly last longer than we will. Therefore, let"s concentrate on our chances of being crushed or asphyxiated."

"As for asphyxiation, captain," I replied, "that isn"t a cause for alarm, because the air tanks are full."

"True," Captain Nemo went on, "but they"ll supply air for only two days. Now then, we"ve been buried beneath the waters for thirty-six hours, and the Nautilus"s heavy atmosphere already needs renewing. In another forty-eight hours, our reserve air will be used up."

"Well then, captain, let"s free ourselves within forty-eight hours!"

"We"ll try to at least, by cutting through one of these walls surrounding us."

"Which one?" I asked.

"Borings will tell us that. I"m going to ground the Nautilus on the lower shelf, then my men will put on their diving suits and attack the thinnest of these ice walls."

"Can the panels in the lounge be left open?"

"Without ill effect. We"re no longer in motion."

Captain Nemo went out. Hissing sounds soon told me that water was being admitted into the ballast tanks. The Nautilus slowly settled and rested on the icy bottom at a depth of 350 meters, the depth at which the lower shelf of ice lay submerged.

"My friends," I said, "we"re in a serious predicament, but I"m counting on your courage and energy."

"Sir," the Canadian replied, "this is no time to bore you with my complaints. I"m ready to do anything I can for the common good."

"Excellent, Ned," I said, extending my hand to the Canadian.

"I might add," he went on, "that I"m as handy with a pick as a harpoon. If I can be helpful to the captain, he can use me any way he wants."

"He won"t turn down your a.s.sistance. Come along, Ned."

I led the Canadian to the room where the Nautilus"s men were putting on their diving suits. I informed the captain of Ned"s proposition, which was promptly accepted. The Canadian got into his underwater costume and was ready as soon as his fellow workers. Each of them carried on his back a Rouquayrol device that the air tanks had supplied with a generous allowance of fresh oxygen. A considerable but necessary drain on the Nautilus"s reserves. As for the Ruhmkorff lamps, they were unnecessary in the midst of these brilliant waters saturated with our electric rays.

After Ned was dressed, I reentered the lounge, whose windows had been uncovered; stationed next to Conseil, I examined the strata surrounding and supporting the Nautilus.

Some moments later, we saw a dozen crewmen set foot on the shelf of ice, among them Ned Land, easily recognized by his tall figure. Captain Nemo was with them.

Before digging into the ice, the captain had to obtain borings, to insure working in the best direction. Long bores were driven into the side walls; but after fifteen meters, the instruments were still impeded by the thickness of those walls. It was futile to attack the ceiling since that surface was the Ice Bank itself, more than 400 meters high. Captain Nemo then bored into the lower surface. There we were separated from the sea by a ten-meter barrier. That"s how thick the iceberg was. From this point on, it was an issue of cutting out a piece equal in surface area to the Nautilus"s waterline. This meant detaching about 6,500 cubic meters, to dig a hole through which the ship could descend below this tract of ice.

Work began immediately and was carried on with tireless tenacity. Instead of digging all around the Nautilus, which would have entailed even greater difficulties, Captain Nemo had an immense trench outlined on the ice, eight meters from our port quarter. Then his men simultaneously staked it off at several points around its circ.u.mference. Soon their picks were vigorously attacking this compact matter, and huge chunks were loosened from its ma.s.s. These chunks weighed less than the water, and by an unusual effect of specific gravity, each chunk took wing, as it were, to the roof of the tunnel, which thickened above by as much as it diminished below. But this hardly mattered so long as the lower surface kept growing thinner.

After two hours of energetic work, Ned Land reentered, exhausted. He and his companions were replaced by new workmen, including Conseil and me. The Nautilus"s chief officer supervised us.

The water struck me as unusually cold, but I warmed up promptly while wielding my pick. My movements were quite free, although they were executed under a pressure of thirty atmospheres.

After two hours of work, reentering to s.n.a.t.c.h some food and rest, I found a noticeable difference between the clean elastic fluid supplied me by the Rouquayrol device and the Nautilus"s atmosphere, which was already charged with carbon dioxide. The air hadn"t been renewed in forty-eight hours, and its life-giving qualities were considerably weakened. Meanwhile, after twelve hours had gone by, we had removed from the outlined surface area a slice of ice only one meter thick, hence about 600 cubic meters. a.s.suming the same work would be accomplished every twelve hours, it would still take five nights and four days to see the undertaking through to completion.

"Five nights and four days!" I told my companions. "And we have oxygen in the air tanks for only two days."

"Without taking into account," Ned answered, "that once we"re out of this d.a.m.ned prison, we"ll still be cooped up beneath the Ice Bank, without any possible contact with the open air!"

An apt remark. For who could predict the minimum time we would need to free ourselves? Before the Nautilus could return to the surface of the waves, couldn"t we all die of asphyxiation? Were this ship and everyone on board doomed to perish in this tomb of ice? It was a dreadful state of affairs. But we faced it head-on, each one of us determined to do his duty to the end.

During the night, in line with my forecasts, a new one-meter slice was removed from this immense socket. But in the morning, wearing my diving suit, I was crossing through the liquid ma.s.s in a temperature of -6 degrees to -7 degrees centigrade, when I noted that little by little the side walls were closing in on each other. The liquid strata farthest from the trench, not warmed by the movements of workmen and tools, were showing a tendency to solidify. In the face of this imminent new danger, what would happen to our chances for salvation, and how could we prevent this liquid medium from solidifying, then cracking the Nautilus"s hull like gla.s.s?

I didn"t tell my two companions about this new danger. There was no point in dampening the energy they were putting into our arduous rescue work. But when I returned on board, I mentioned this serious complication to Captain Nemo.

"I know," he told me in that calm tone the most dreadful outlook couldn"t change. "It"s one more danger, but I don"t know any way of warding it off. Our sole chance for salvation is to work faster than the water solidifies. We"ve got to get there first, that"s all."

Get there first! By then I should have been used to this type of talk!

For several hours that day, I wielded my pick doggedly. The work kept me going. Besides, working meant leaving the Nautilus, which meant breathing the clean oxygen drawn from the air tanks and supplied by our equipment, which meant leaving the thin, foul air behind.

Near evening one more meter had been dug from the trench. When I returned on board, I was wellnigh asphyxiated by the carbon dioxide saturating the air. Oh, if only we had the chemical methods that would enable us to drive out this noxious gas! There was no lack of oxygen. All this water contained a considerable amount, and after it was decomposed by our powerful batteries, this life-giving elastic fluid could have been restored to us. I had thought it all out, but to no avail because the carbon dioxide produced by our breathing permeated every part of the ship. To absorb it, we would need to fill containers with pota.s.sium hydroxide and shake them continually. But this substance was missing on board and nothing else could replace it.

That evening Captain Nemo was forced to open the spigots of his air tanks and shoot a few spouts of fresh oxygen through the Nautilus"s interior. Without this precaution we wouldn"t have awakened the following morning.

The next day, March 26, I returned to my miner"s trade, working to remove the fifth meter. The Ice Bank"s side walls and underbelly had visibly thickened. Obviously they would come together before the Nautilus could break free. For an instant I was gripped by despair. My pick nearly slipped from my hands. What was the point of this digging if I was to die smothered and crushed by this water turning to stone, a torture undreamed of by even the wildest savages! I felt like I was lying in the jaws of a fearsome monster, jaws irresistibly closing.

Supervising our work, working himself, Captain Nemo pa.s.sed near me just then. I touched him with my hand and pointed to the walls of our prison. The starboard wall had moved forward to a point less than four meters from the Nautilus"s hull.

The captain understood and gave me a signal to follow him. We returned on board. My diving suit removed, I went with him to the lounge.

"Professor Aronnax," he told me, "this calls for heroic measures, or we"ll be sealed up in this solidified water as if it were cement."

"Yes!" I said. "But what can we do?"

"Oh," he exclaimed, "if only my Nautilus were strong enough to stand that much pressure without being crushed!"

"Well?" I asked, not catching the captain"s meaning.

"Don"t you understand," he went on, "that the congealing of this water could come to our rescue? Don"t you see that by solidifying, it could burst these tracts of ice imprisoning us, just as its freezing can burst the hardest stones? Aren"t you aware that this force could be the instrument of our salvation rather than our destruction?"

"Yes, captain, maybe so. But whatever resistance to crushing the Nautilus may have, it still couldn"t stand such dreadful pressures, and it would be squashed as flat as a piece of sheet iron."

"I know it, sir. So we can"t rely on nature to rescue us, only our own efforts. We must counteract this solidification. We must hold it in check. Not only are the side walls closing in, but there aren"t ten feet of water ahead or astern of the Nautilus. All around us, this freeze is gaining fast."

"How long," I asked, "will the oxygen in the air tanks enable us to breathe on board?"

The captain looked me straight in the eye.

"After tomorrow," he said, "the air tanks will be empty!"

I broke out in a cold sweat. But why should I have been startled by this reply? On March 22 the Nautilus had dived under the open waters at the pole. It was now the 26th. We had lived off the ship"s stores for five days! And all remaining breathable air had to be saved for the workmen. Even today as I write these lines, my sensations are so intense that an involuntary terror sweeps over me, and my lungs still seem short of air!

Meanwhile, motionless and silent, Captain Nemo stood lost in thought. An idea visibly crossed his mind. But he seemed to brush it aside. He told himself no. At last these words escaped his lips: "Boiling water!" he muttered.

"Boiling water?" I exclaimed.

"Yes, sir. We"re shut up in a relatively confined area. If the Nautilus"s pumps continually injected streams of boiling water into this s.p.a.ce, wouldn"t that raise its temperature and delay its freezing?"

"It"s worth trying!" I said resolutely.

"So let"s try it, professor."

By then the thermometer gave -7 degrees centigrade outside. Captain Nemo led me to the galley where a huge distilling mechanism was at work, supplying drinking water via evaporation. The mechanism was loaded with water, and the full electric heat of our batteries was thrown into coils awash in liquid. In a few minutes the water reached 100 degrees centigrade. It was sent to the pumps while new water replaced it in the process. The heat generated by our batteries was so intense that after simply going through the mechanism, water drawn cold from the sea arrived boiling hot at the body of the pump.

The steaming water was injected into the icy water outside, and after three hours had pa.s.sed, 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 a.s.sured 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!
