On this occasion Captain Nemo told me that he intended to reach the Indian Ocean via the Torres Strait. This was the extent of his remarks. Ned saw with pleasure that this course would bring us, once again, closer to European seas.

The Torres Strait is regarded as no less dangerous for its bristling reefs than for the savage inhabitants of its coasts. It separates Queensland from the huge island of Papua, also called New Guinea.

Papua is 400 leagues long by 130 leagues wide, with a surface area of 40,000 geographic leagues. It's located between latitude 0 degrees 19' and 10 degrees 2' south, and between longitude 128 degrees 23' and 146 degrees 15'. At noon, while the chief officer was taking the sun's altitude, I spotted the summits of the Arfak Mountains, rising in terraces and ending in sharp peaks.

Discovered in 1511 by the Portuguese Francisco Serrano, these shores were successively visited by Don Jorge de Meneses in 1526, by Juan de Grijalva in 1527, by the Spanish general Alvaro de Saavedra in 1528, by Inigo Ortiz in 1545, by the Dutchman Schouten in 1616, by Nicolas Sruick in 1753, by Tasman, Dampier, Fumel, Carteret, Edwards, Bougainville, Cook, McClure, and Thomas Forrest, by Rear Admiral d'Entrecasteaux in 1792, by Louis-Isidore Duperrey in 1823, and by Captain Dumont d'Urville in 1827. "It's the heartland of the blacks who occupy all Malaysia," Mr. de Rienzi has said; and I hadn't the foggiest inkling that sailors' luck was about to bring me face to face with these daunting Andaman aborigines.

So the Nautilus hove before the entrance to the world's most dangerous strait, a passageway that even the boldest navigators hesitated to clear: the strait that Luis Vaez de Torres faced on returning from the South Seas in Melanesia, the strait in which sloops of war under Captain Dumont d'Urville ran aground in 1840 and nearly miscarried with all hands. And even the Nautilus, rising superior to every danger in the sea, was about to become intimate with its coral reefs.

The Torres Strait is about thirty-four leagues wide, but it's obstructed by an incalculable number of islands, islets, breakers, and rocks that make it nearly impossible to navigate. Consequently, Captain Nemo took every desired precaution in crossing it. Floating flush with the water, the Nautilus moved ahead at a moderate pace. Like a cetacean's tail, its propeller churned the waves slowly.

Taking advantage of this situation, my two companions and I found seats on the ever-deserted platform. In front of us stood the pilothouse, and unless I'm extremely mistaken, Captain Nemo must have been inside, steering his Nautilus himself.

Under my eyes I had the excellent charts of the Torres Strait that had been surveyed and drawn up by the hydrographic engineer Vincendon Dumoulin and Sublieutenant (now Admiral) Coupvent-Desbois, who were part of Dumont d'Urville's general staff during his final voyage to circumnavigate the globe. These, along with the efforts of Captain King, are the best charts for untangling the snarl of this narrow passageway, and I consulted them with scrupulous care.

Around the Nautilus the sea was boiling furiously. A stream of waves, bearing from southeast to northwest at a speed of two and a half miles per hour, broke over heads of coral emerging here and there.

"That's one rough sea!" Ned Land told me.

"Abominable indeed," I replied, "and hardly suitable for a craft like the Nautilus."

"That damned captain," the Canadian went on, "must really be sure of his course, because if these clumps of coral so much as brush us, they'll rip our hull into a thousand pieces!"

The situation was indeed dangerous, but as if by magic, the Nautilus seemed to glide right down the middle of these rampaging reefs. It didn't follow the exact course of the Zealous and the new Astrolabe, which had proved so ill-fated for Captain Dumont d'Urville. It went more to the north, hugged the Murray Islands, and returned to the southwest near Cumberland Passage. I thought it was about to charge wholeheartedly into this opening, but it went up to the northwest, through a large number of little-known islands and islets, and steered toward Tound Island and the Bad Channel.
