The Nautilus passed over these lush, luxuriant depths with tremendous speed. Near evening it approached the Falkland Islands, whose rugged summits I recognized the next day. The sea was of moderate depth. So not without good reason, I assumed that these two islands, plus the many islets surrounding them, used to be part of the Magellan coastline. The Falkland Islands were probably discovered by the famous navigator John Davis, who gave them the name Davis Southern Islands. Later Sir Richard Hawkins called them the Maidenland, after the Blessed Virgin. Subsequently, at the beginning of the 18th century, they were named the Malouines by fishermen from Saint-Malo in Brittany, then finally dubbed the Falklands by the English, to whom they belong today.
In these waterways our nets brought up fine samples of algae, in particular certain fucus plants whose roots were laden with the world’s best mussels. Geese and duck alighted by the dozens on the platform and soon took their places in the ship’s pantry. As for fish, I specifically observed some bony fish belonging to the goby genus, especially some gudgeon two decimeters long, sprinkled with whitish and yellow spots.
I likewise marveled at the numerous medusas, including the most beautiful of their breed, the compass jellyfish, unique to the Falkland seas. Some of these jellyfish were shaped like very smooth, semispheric parasols with russet stripes and fringes of twelve neat festoons. Others looked like upside-down baskets from which wide leaves and long red twigs were gracefully trailing. They swam with quiverings of their four leaflike arms, letting the opulent tresses of their tentacles dangle in the drift. I wanted to preserve a few specimens of these delicate zoophytes, but they were merely clouds, shadows, illusions, melting and evaporating outside their native element.
When the last tips of the Falkland Islands had disappeared below the horizon, the Nautilus submerged to a depth between twenty and twenty-five meters and went along the South American coast. Captain Nemo didn’t put in an appearance.
We didn’t leave these Patagonian waterways until April 3, sometimes cruising under the ocean, sometimes on its surface. The Nautilus passed the wide estuary formed by the mouth of the Rio de la Plata, and on April 4 we lay abreast of Uruguay, albeit fifty miles out. Keeping to its northerly heading, it followed the long windings of South America. By then we had fared 16,000 leagues since coming on board in the seas of Japan.
Near eleven o’clock in the morning, we cut the Tropic of Capricorn on the 37th meridian, passing well out from Cape Frio. Much to Ned Land’s displeasure, Captain Nemo had no liking for the neighborhood of Brazil’s populous shores, because he shot by with dizzying speed. Not even the swiftest fish or birds could keep up with us, and the natural curiosities in these seas completely eluded our observation.
This speed was maintained for several days, and on the evening of April 9, we raised South America’s easternmost tip, Cape São Roque. But then the Nautilus veered away again and went looking for the lowest depths of an underwater valley gouged between this cape and Sierra Leone on the coast of Africa. Abreast of the West Indies, this valley forks into two arms, and to the north it ends in an enormous depression 9,000 meters deep. From this locality to the Lesser Antilles, the ocean’s geologic profile features a steeply cut cliff six kilometers high, and abreast of the Cape Verde Islands, there’s another wall just as imposing; together these two barricades confine the whole submerged continent of Atlantis. The floor of this immense valley is made picturesque by mountains that furnish these underwater depths with scenic views. This description is based mostly on certain hand-drawn charts kept in the Nautilus’s library, charts obviously rendered by Captain Nemo himself from his own personal observations.
For two days we visited these deep and deserted waters by means of our slanting fins. The Nautilus would do long, diagonal dives that took us to every level. But on April 11 it rose suddenly, and the shore reappeared at the mouth of the Amazon River, a huge estuary whose outflow is so considerable, it desalts the sea over an area of several leagues.
We cut the Equator. Twenty miles to the west lay Guiana, French territory where we could easily have taken refuge. But the wind was blowing a strong gust, and the furious billows would not allow us to face them in a mere skiff. No doubt Ned Land understood this because he said nothing to me. For my part, I made no allusion to his escape plans because I didn’t want to push him into an attempt that was certain to misfire.
I was readily compensated for this delay by fascinating research. During those two days of April 11-12, the Nautilus didn’t leave the surface of the sea, and its trawl brought up a simply miraculous catch of zoophytes, fish, and reptiles.
