“I’d like to believe you, captain,” I went on in a tone of some sarcasm. “Oh I do believe you! Let’s forge ahead! There are no obstacles for us! Let’s shatter this Ice Bank! Let’s blow it up, and if it still resists, let’s put wings on the Nautilus and fly over it!” “Over it, professor?” Captain Nemo replied serenely. “No, not over it, but under it.” “Under it!” I exclaimed. A sudden insight into Captain Nemo’s plans had just flashed through my mind. I understood. The marvelous talents of his Nautilus would be put to work once again in this superhuman undertaking! “I can see we’re starting to understand each other, professor,” Captain Nemo told me with a half smile. “You already glimpse the potential—myself, I’d say the success—of this attempt. Maneuvers that aren’t feasible for an ordinary ship are easy for the Nautilus. If a continent emerges at the pole, we’ll stop at that continent. But on the other hand, if open sea washes the pole, we’ll go to that very place!” “Right,” I said, carried away by the captain’s logic. “Even though the surface of the sea has solidified into ice, its lower strata are still open, thanks to that divine justice that puts the maximum density of salt water one degree above its freezing point. And if I’m not mistaken, the submerged part of this Ice Bank is in a four-to-one ratio to its emerging part.” “Very nearly, professor. For each foot of iceberg above the sea, there are three more below. Now then, since these ice mountains don’t exceed a height of 100 meters, they sink only to a depth of 300 meters. And what are 300 meters to the Nautilus?” “A mere nothing, sir.” “We could even go to greater depths and find that temperature layer common to all ocean water, and there we’d brave with impunity the -30 degrees or -40 degrees cold on the surface.” “True, sir, very true,” I replied with growing excitement. “Our sole difficulty,” Captain Nemo went on, “lies in our staying submerged for several days without renewing our air supply.” “That’s all?” I answered. “The Nautilus has huge air tanks; we’ll fill them up and they’ll supply all the oxygen we need.” “Good thinking, Professor Aronnax,” the captain replied with a smile. “But since I don’t want to be accused of foolhardiness, I’m giving you all my objections in advance.” “You have more?” “Just one. If a sea exists at the South Pole, it’s possible this sea may be completely frozen over, so we couldn’t come up to the surface!” “My dear sir, have you forgotten that the Nautilus is armed with a fearsome spur? Couldn’t it be launched diagonally against those tracts of ice, which would break open from the impact?” “Ah, professor, you’re full of ideas today!”
