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 Sáo 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.

Some zoophytes were dredged up by the chain of our trawl. Most were lovely sea anemone belonging to the family Actinidia, including among other species, the Phyctalis protexta, native to this part of the ocean: a small cylindrical trunk adorned with vertical lines, mottled with red spots, and crowned by a wondrous blossoming of tentacles. As for mollusks, they consisted of exhibits I had already observed: turret snails, olive shells of the "tent olive" species with neatly intersecting lines and russet spots standing out sharply against a flesh-colored background, fanciful spider conchs that looked like petrified scorpions, transparent glass snails, argonauts, some highly edible cuttlefish, and certain species of squid that the naturalists of antiquity classified with the flying fish, which are used chiefly as bait for catching cod.

As for the fish in these waterways, I noted various species that I hadn't yet had the opportunity to study. Among cartilaginous fish: some brook lamprey, a type of eel fifteen inches long, head greenish, fins violet, back bluish gray, belly a silvery brown strewn with bright spots, iris of the eye encircled in gold, unusual animals that the Amazon's current must have swept out to sea because their natural habitat is fresh water; sting rays, the snout pointed, the tail long, slender, and armed with an extensive jagged sting; small one-meter sharks with gray and whitish hides, their teeth arranged in several backward-curving rows, fish commonly known by the name carpet shark; batfish, a sort of reddish isosceles triangle half a meter long, whose pectoral fins are attached by fleshy extensions that make these fish look like bats, although an appendage made of horn, located near the nostrils, earns them the nickname of sea unicorns; lastly, a couple species of triggerfish, the cucuyo whose stippled flanks glitter with a sparkling gold color, and the bright purple leatherjacket whose hues glisten like a pigeon's throat.
