But nothing binds us to Captain Nemo. He believes that escaping from the Nautilus is impossible. We are not even constrained by our word of honor. No promises fetter us. We’re simply captives, prisoners masquerading under the name “guests” for the sake of everyday courtesy. Even so, Ned Land hasn’t given up all hope of recovering his freedom. He’s sure to take advantage of the first chance that comes his way. No doubt I will do likewise. And yet I will feel some regret at making off with the Nautilus’s secrets, so generously unveiled for us by Captain Nemo! Because, ultimately, should we detest or admire this man? Is he the persecutor or the persecuted? And in all honesty, before I leave him forever, I want to finish this underwater tour of the world, whose first stages have been so magnificent. I want to observe the full series of these wonders gathered under the seas of our globe. I want to see what no man has seen yet, even if I must pay for this insatiable curiosity with my life! What are my discoveries to date? Nothing, relatively speaking—since so far we’ve covered only 6,000 leagues across the Pacific! Nevertheless, I’m well aware that the Nautilus is drawing near to populated shores, and if some chance for salvation becomes available to us, it would be sheer cruelty to sacrifice my companions to my passion for the unknown. I must go with them, perhaps even guide them. But will this opportunity ever arise? The human being, robbed of his free will, craves such an opportunity; but the scientist, forever inquisitive, dreads it. That day, January 21, 1868, the chief officer went at noon to take the sun’s altitude. I climbed onto the platform, lit a cigar, and watched him at work. It seemed obvious to me that this man didn’t understand French, because I made several remarks in a loud voice that were bound to provoke him to some involuntary show of interest had he understood them; but he remained mute and emotionless. While he took his sights with his sextant, one of the Nautilus’s sailors—that muscular man who had gone with us to Crespo Island during our first underwater excursion—came up to clean the glass panes of the beacon. I then examined the fittings of this mechanism, whose power was increased a hundredfold by biconvex lenses that were designed like those in a lighthouse and kept its rays productively focused. This electric lamp was so constructed as to yield its maximum illuminating power. In essence, its light was generated in a vacuum, insuring both its steadiness and intensity. Such a vacuum also reduced wear on the graphite points between which the luminous arc expanded. This was an important savings for Captain Nemo, who couldn’t easily renew them. But under these conditions, wear and tear were almost nonexistent. When the Nautilus was ready to resume its underwater travels, I went below again to the lounge. The hatches closed once more, and our course was set due west.
