On January 13, arriving in the Timor Sea, Captain Nemo raised the island of that name at longitude 122 degrees. This island, whose surface area measures 1,625 square leagues, is governed by rajahs. These aristocrats deem themselves the sons of crocodiles, in other words, descendants with the most exalted origins to which a human being can lay claim. Accordingly, their scaly ancestors infest the island’s rivers and are the subjects of special veneration. They are sheltered, nurtured, flattered, pampered, and offered a ritual diet of nubile maidens; and woe to the foreigner who lifts a finger against these sacred saurians.
But the Nautilus wanted nothing to do with these nasty animals. Timor Island was visible for barely an instant at noon while the chief officer determined his position. I also caught only a glimpse of little Roti Island, part of this same group, whose women have a well-established reputation for beauty in the Malaysian marketplace.
After our position fix, the Nautilus’s latitude bearings were modulated to the southwest. Our prow pointed to the Indian Ocean. Where would Captain Nemo’s fancies take us? Would he head up to the shores of Asia? Would he pull nearer to the beaches of Europe? Unlikely choices for a man who avoided populated areas! So would he go down south? Would he double the Cape of Good Hope, then Cape Horn, and push on to the Antarctic pole? Finally, would he return to the seas of the Pacific, where his Nautilus could navigate freely and easily? Time would tell.
After cruising along the Cartier, Hibernia, Seringapatam, and Scott reefs, the solid element’s last exertions against the liquid element, we were beyond all sight of shore by January 14. The Nautilus slowed down in an odd manner, and very unpredictable in its ways, it sometimes swam in the midst of the waters, sometimes drifted on their surface.
During this phase of our voyage, Captain Nemo conducted interesting experiments on the different temperatures in various strata of the sea. Under ordinary conditions, such readings are obtained using some pretty complicated instruments whose findings are dubious to say the least, whether they’re thermometric sounding lines, whose glass often shatters under the water’s pressure, or those devices based on the varying resistance of metals to electric currents. The results so obtained can’t be adequately double-checked. By contrast, Captain Nemo would seek the sea’s temperature by going himself into its depths, and when he placed his thermometer in contact with the various layers of liquid, he found the sought-for degree immediately and with certainty.
And so, by loading up its ballast tanks, or by sinking obliquely with its slanting fins, the Nautilus successively reached depths of 3,000, 4,000, 5,000, 7,000, 9,000, and 10,000 meters, and the ultimate conclusion from these experiments was that, in all latitudes, the sea had a permanent temperature of 4.5 degrees centigrade at a depth of 1,000 meters.
I watched these experiments with the most intense fascination. Captain Nemo brought a real passion to them. I often wondered why he took these observations. Were they for the benefit of his fellow man? It was unlikely, because sooner or later his work would perish with him in some unknown sea! Unless he intended the results of his experiments for me. But that meant this strange voyage of mine would come to an end, and no such end was in sight.
Be that as it may, Captain Nemo also introduced me to the different data he had obtained on the relative densities of the water in our globe’s chief seas. From this news I derived some personal enlightenment having nothing to do with science.
It happened the morning of January 15. The captain, with whom I was strolling on the platform, asked me if I knew how salt water differs in density from sea to sea. I said no, adding that there was a lack of rigorous scientific observations on this subject.
“I’ve taken such observations,” he told me, “and I can vouch for their reliability.”
