The Nautilus had cleared 8,100 miles. We logged 9,720 miles when we passed between the Tonga Islands, where crews from the Argo, Port-au-Prince, and Duke of Portland had perished, and the island group of Samoa, scene of the slaying of Captain de Langle, friend of that long-lost navigator, the Count de La Pérouse. Then we raised the Fiji Islands, where savages slaughtered sailors from the Union, as well as Captain Bureau, commander of the Darling Josephine out of Nantes, France.

Extending over an expanse of 100 leagues north to south, and over 90 leagues east to west, this island group lies between latitude 2 degrees and 6 degrees south, and between longitude 174 degrees and 179 degrees west. It consists of a number of islands, islets, and reefs, among which we noted the islands of Viti Levu, Vanua Levu, and Kadavu.

It was the Dutch navigator Tasman who discovered this group in 1643, the same year the Italian physicist Torricelli invented the barometer and King Louis XIV ascended the French throne. I’ll let the reader decide which of these deeds was more beneficial to humanity. Coming later, Captain Cook in 1774, Rear Admiral d’Entrecasteaux in 1793, and finally Captain Dumont d’Urville in 1827, untangled the whole chaotic geography of this island group. The Nautilus drew near Wailea Bay, an unlucky place for England’s Captain Dillon, who was the first to shed light on the longstanding mystery surrounding the disappearance of ships under the Count de La Pérouse.

This bay, repeatedly dredged, furnished a huge supply of excellent oysters. As the Roman playwright Seneca recommended, we opened them right at our table, then stuffed ourselves. These mollusks belonged to the species known by name as Ostrea lamellosa, whose members are quite common off Corsica. This Wailea oysterbank must have been extensive, and for certain, if they hadn’t been controlled by numerous natural checks, these clusters of shellfish would have ended up jam-packing the bay, since as many as 2,000,000 eggs have been counted in a single individual.

And if Mr. Ned Land did not repent of his gluttony at our oyster fest, it’s because oysters are the only dish that never causes indigestion. In fact, it takes no less than sixteen dozen of these headless mollusks to supply the 315 grams that satisfy one man’s minimum daily requirement for nitrogen.

On December 25 the Nautilus navigated amid the island group of the New Hebrides, which the Portuguese seafarer Queirós discovered in 1606, which Commander Bougainville explored in 1768, and to which Captain Cook gave its current name in 1773. This group is chiefly made up of nine large islands and forms a 120-league strip from the north-northwest to the south-southeast, lying between latitude 2 degrees and 15 degrees south, and between longitude 164 degrees and 168 degrees. At the moment of our noon sights, we passed fairly close to the island of Aurou, which looked to me like a mass of green woods crowned by a peak of great height.

That day it was yuletide, and it struck me that Ned Land badly missed celebrating “Christmas,” that genuine family holiday where Protestants are such zealots.

I hadn’t seen Captain Nemo for over a week, when, on the morning of the 27th, he entered the main lounge, as usual acting as if he’d been gone for just five minutes. I was busy tracing the Nautilus’s course on the world map. The captain approached, placed a finger over a position on the chart, and pronounced just one word:

“Vanikoro.”

This name was magic! It was the name of those islets where vessels under the Count de La Pérouse had miscarried. I straightened suddenly.
