Chapter 18: Vanikoro

This terrible spectacle was the forerunner of the series of maritime catastrophes that the Nautilus was destined to meet with in its route. As long as it went through more frequented waters, we often saw the hulls of shipwrecked vessels that were rotting in the depths, and deeper down cannons, bullets, anchors, chains, and a thousand other iron materials eaten up by rust. However, on the 11th of December we sighted the Pomotou Islands, the old “dangerous group” of Bougainville, that extend over a space of 500 leagues at E.S.E. to W.N.W., from the Island Ducie to that of Lazareff. This group covers an area of 370 square leagues, and it is formed of sixty groups of islands, among which the Gambier group is remarkable, over which France exercises sway. These are coral islands, slowly raised, but continuous, created by the daily work of polypi. Then this new island will be joined later on to the neighboring groups, and a fifth continent will stretch from New Zealand and New Caledonia, and from thence to the Marquesas.

One day, when I was suggesting this theory to Captain Nemo, he replied coldly:

“The earth does not want new continents, but new men.”

Chance had conducted the Nautilus towards the Island of Clermont-Tonnere, one of the most curious of the group, that was discovered in 1822 by Captain Bell of the Minerva. I could study now the madreporal system, to which are due the islands in this ocean.

Madrepores (which must not be mistaken for corals) have a tissue lined with a calcareous crust, and the modifications of its structure have induced M. Milne Edwards, my worthy master, to class them into five sections. The animalcule that the marine polypus secretes live by millions at the bottom of their cells. Their calcareous deposits become rocks, reefs, and large and small islands. Here they form a ring, surrounding a little inland lake, that communicates with the sea by means of gaps. There they make barriers of reefs like those on the coasts of New Caledonia and the various Pomoton islands. In other places, like those at Reunion and at Maurice, they raise fringed reefs, high, straight walls, near which the depth of the ocean is considerable.

Some cable-lengths off the shores of the Island of Clermont I admired the gigantic work accomplished by these microscopical workers. These walls are specially the work of those madrepores known as milleporas, porites, madrepores, and astraeas. These polypi are found particularly in the rough beds of the sea, near the surface; and consequently it is from the upper part that they begin their operations, in which they bury themselves by degrees with the debris of the secretions that support them. Such is, at least, Darwin’s theory, who thus explains the formation of the atolls, a superior theory (to my mind) to that given of the foundation of the madreporical works, summits of mountains or volcanoes, that are submerged some feet below the level of the sea.

I could observe closely these curious walls, for perpendicularly they were more than 300 yards deep, and our electric sheets lighted up this calcareous matter brilliantly. Replying to a question Conseil asked me as to the time these colossal barriers took to be raised, I astonished him much by telling him that learned men reckoned it about the eighth of an inch in a hundred years.

Towards evening Clermont-Tonnerre was lost in the distance, and the route of the Nautilus was sensibly changed. After having crossed the tropic of Capricorn in 135° longitude, it sailed W.N.W., making again for the tropical zone. Although the summer sun was very strong, we did not suffer from heat, for at fifteen or twenty fathoms below the surface, the temperature did not rise above from ten to twelve degrees.

On 15th of December, we left to the east the bewitching group of the Societies and the graceful Tahiti, queen of the Pacific. I saw in the morning, some miles to the windward, the elevated summits of the island. These waters furnished our table with excellent fish, mackerel, bonitos, and some varieties of a sea-serpent.

On the 25th of December the Nautilus sailed into the midst of the New Hebrides, discovered by Quiros in 1606, and that Bougainville explored in 1768, and to which Cook gave its present name in 1773. This group is composed principally of nine large islands, that form a band of 120 leagues N.N.S. to S.S.W., between 15° and 2° S. lat., and 164 deg. and 168° long. We passed tolerably near to the Island of Aurou, that at noon looked like a mass of green woods, surmounted by a peak of great height.

That day being Christmas Day, Ned Land seemed to regret sorely the non-celebration of “Christmas,” the family fete of which Protestants are so fond. I had not seen Captain Nemo for a week, when, on the morning of the 27th, he came into the large drawing-room, always seeming as if he had seen you five minutes before. I was busily tracing the route of the Nautilus on the planisphere. The Captain came up to me, put his finger on one spot on the chart, and said this single word.

“Vanikoro.”

The effect was magical! It was the name of the islands on which La Perouse had been lost! I rose suddenly.

“The Nautilus has brought us to Vanikoro?” I asked.

“Yes, Professor,” said the Captain.

“And I can visit the celebrated islands where the Boussole and the Astrolabe struck?”

“If you like, Professor.”

“When shall we be there?”

“We are there now.”

Followed by Captain Nemo, I went up on to the platform, and greedily scanned the horizon.

To the N.E. two volcanic islands emerged of unequal size, surrounded by a coral reef that measured forty miles in circumference. We were close to Vanikoro, really the one to which Dumont d’Urville gave the name of Isle de la Recherche, and exactly facing the little harbour of Vanou, situated in 16° 4’ S. lat., and 164° 32’ E. long. The earth seemed covered with verdure from the shore to the summits in the interior, that were crowned by Mount Kapogo, 476 feet high. The Nautilus, having passed the outer belt of rocks by a narrow strait, found itself among breakers where the sea was from thirty to forty fathoms deep. Under the verdant shade of some mangroves I perceived some savages, who appeared greatly surprised at our approach. In the long black body, moving between wind and water, did they not see some formidable cetacean that they regarded with suspicion?

Just then Captain Nemo asked me what I knew about the wreck of La Perouse.

“Only what everyone knows, Captain,” I replied.

“And could you tell me what everyone knows about it?” he inquired, ironically.

“Easily.”

I related to him all that the last works of Dumont d’Urville had made known--works from which the following is a brief account.

La Perouse, and his second, Captain de Langle, were sent by Louis XVI, in 1785, on a voyage of circumnavigation. They embarked in the corvettes Boussole and the Astrolabe, neither of which were again heard of. In 1791, the French Government, justly uneasy as to the fate of these two sloops, manned two large merchantmen, the Recherche and the Esperance, which left Brest the 28th of September under the command of Bruni d’Entrecasteaux.

Two months after, they learned from Bowen, commander of the Albemarle, that the debris of shipwrecked vessels had been seen on the coasts of New Georgia. But D’Entrecasteaux, ignoring this communication--rather uncertain, besides--directed his course towards the Admiralty Islands, mentioned in a report of Captain Hunter’s as being the place where La Perouse was wrecked.
