But the Nautilus kept gravitating southward. On May 30, in sight of Land's End, it passed between the lowermost tip of England and the Scilly Islands, which it left behind to starboard.

If it was going to enter the English Channel, it clearly needed to head east. It did not.

All day long on May 31, the Nautilus swept around the sea in a series of circles that had me deeply puzzled. It seemed to be searching for a locality that it had some trouble finding. At noon Captain Nemo himself came to take our bearings. He didn't address a word to me. He looked gloomier than ever. What was filling him with such sadness? Was it our proximity to these European shores? Was he reliving his memories of that country he had left behind? If so, what did he feel? Remorse or regret? For a good while these thoughts occupied my mind, and I had a hunch that fate would soon give away the captain's secrets.

The next day, June 1, the Nautilus kept to the same tack. It was obviously trying to locate some precise spot in the ocean. Just as on the day before, Captain Nemo came to take the altitude of the sun. The sea was smooth, the skies clear. Eight miles to the east, a big steamship was visible on the horizon line. No flag was flapping from the gaff of its fore-and-aft sail, and I couldn't tell its nationality.

A few minutes before the sun passed its zenith, Captain Nemo raised his sextant and took his sights with the utmost precision. The absolute calm of the waves facilitated this operation. The Nautilus lay motionless, neither rolling nor pitching.

I was on the platform just then. After determining our position, the captain pronounced only these words:

"It's right here!"

He went down the hatch. Had he seen that vessel change course and seemingly head toward us? I'm unable to say.

I returned to the lounge. The hatch closed, and I heard water hissing in the ballast tanks. The Nautilus began to sink on a vertical line, because its propeller was in check and no longer furnished any forward motion.

Some minutes later it stopped at a depth of 833 meters and came to rest on the seafloor.

The ceiling lights in the lounge then went out, the panels opened, and through the windows I saw, for a half-mile radius, the sea brightly lit by the beacon's rays.

I looked to port and saw nothing but the immenseness of these tranquil waters.

To starboard, a prominent bulge on the sea bottom caught my attention. You would have thought it was some ruin enshrouded in a crust of whitened seashells, as if under a mantle of snow. Carefully examining this mass, I could identify the swollen outlines of a ship shorn of its masts, which must have sunk bow first. This casualty certainly dated from some far-off time. To be so caked with the limestone of these waters, this wreckage must have spent many a year on the ocean floor.

What ship was this? Why had the Nautilus come to visit its grave? Was it something other than a maritime accident that had dragged this craft under the waters?

I wasn't sure what to think, but next to me I heard Captain Nemo's voice slowly say:

"Originally this ship was christened the Marseillais. It carried seventy-four cannons and was launched in 1762. On August 13, 1778, commanded by La Poype-Vertrieux, it fought valiantly against the Preston. On July 4, 1779, as a member of the squadron under Admiral d'Estaing, it assisted in the capture of the island of Grenada. On September 5, 1781, under the Count de Grasse, it took part in the Battle of Chesapeake Bay. In 1794 the new Republic of France changed the name of this ship. On April 16 of that same year, it joined the squadron at Brest under Rear Admiral Villaret de Joyeuse, who was entrusted with escorting a convoy of wheat coming from America under the command of Admiral Van Stabel. In this second year of the French Revolutionary Calendar, on the 11th and 12th days in the Month of Pasture, this squadron fought an encounter with English vessels. Sir, today is June 1, 1868, or the 13th day in the Month of Pasture. Seventy-four years ago to the day, at this very spot in latitude 47 degrees 24' and longitude 17 degrees 28', this ship sank after a heroic battle; its three masts gone, water in its hold, a third of its crew out of action, it preferred to go to the bottom with its 356 seamen rather than surrender; and with its flag nailed up on the afterdeck, it disappeared beneath the waves to shouts of 'Long live the Republic!'"

"This is the Avenger!" I exclaimed.

"Yes, sir! The Avenger! A splendid name!" Captain Nemo murmured, crossing his arms.
