As for Ned Land, he ended our talk in his best speechifying style: "That's all fine and dandy. But in my humble opinion, a life in jail is a life without joy."

For four days until February 3, the Nautilus inspected the Gulf of Oman at various speeds and depths. It seemed to be traveling at random, as if hesitating over which course to follow, but it never crossed the Tropic of Cancer.

After leaving this gulf we raised Muscat for an instant, the most important town in the country of Oman. I marveled at its strange appearance in the midst of the black rocks surrounding it, against which the white of its houses and forts stood out sharply. I spotted the rounded domes of its mosques, the elegant tips of its minarets, and its fresh, leafy terraces. But it was only a fleeting vision, and the Nautilus soon sank beneath the dark waves of these waterways.

Then our ship went along at a distance of six miles from the Arabic coasts of Mahra and Hadhramaut, their undulating lines of mountains relieved by a few ancient ruins. On February 5 we finally put into the Gulf of Aden, a genuine funnel stuck into the neck of Bab el Mandeb and bottling these Indian waters in the Red Sea.

On February 6 the Nautilus cruised in sight of the city of Aden, perched on a promontory connected to the continent by a narrow isthmus, a sort of inaccessible Gibraltar whose fortifications the English rebuilt after capturing it in 1839. I glimpsed the octagonal minarets of this town, which used to be one of the wealthiest, busiest commercial centers along this coast, as the Arab historian Idrisi tells it.

I was convinced that when Captain Nemo reached this point, he would back out again; but I was mistaken, and much to my surprise, he did nothing of the sort.

The next day, February 7, we entered the Strait of Bab el Mandeb, whose name means "Gate of Tears" in the Arabic language. Twenty miles wide, it's only fifty-two kilometers long, and with the Nautilus launched at full speed, clearing it was the work of barely an hour. But I didn't see a thing, not even Perim Island where the British government built fortifications to strengthen Aden's position. There were many English and French steamers plowing this narrow passageway, liners going from Suez to Bombay, Calcutta, Melbourne, Réunion Island, and Mauritius; far too much traffic for the Nautilus to make an appearance on the surface. So it wisely stayed in midwater.

Finally, at noon, we were plowing the waves of the Red Sea.

The Red Sea: that great lake so famous in biblical traditions, seldom replenished by rains, fed by no important rivers, continually drained by a high rate of evaporation, its water level dropping a meter and a half every year! If it were fully landlocked like a lake, this odd gulf might dry up completely; on this score it's inferior to its neighbors, the Caspian Sea and the Dead Sea, whose levels lower only to the point where their evaporation exactly equals the amounts of water they take to their hearts.

This Red Sea is 2,600 kilometers long with an average width of 240. In the days of the

Ptolemies and the Roman emperors, it was a great commercial artery for the world, and when its isthmus has been cut through, it will completely regain that bygone importance that the Suez railways have already brought back in part.

I would not even attempt to understand the whim that induced Captain Nemo to take us into this gulf. But I wholeheartedly approved of the Nautilus's entering it. It adopted a medium pace, sometimes staying on the surface, sometimes diving to avoid some ship, and so I could observe both the inside and topside of this highly unusual sea.

On February 8, as early as the first hours of daylight, Mocha appeared before us: a town now in ruins, whose walls would collapse at the mere sound of a cannon, and which shelters a few leafy date trees here and there. This once-important city used to contain six public marketplaces plus twenty-six mosques, and its walls, protected by fourteen forts, fashioned a three-kilometer girdle around it.
