At this point indicated on the planisphere one of these currents was rolling, the Kuro-Scivo of the Japanese, the Black River, which, leaving the Gulf of Bengal, where it is warmed by the perpendicular rays of a tropical sun, crosses the Straits of Malacca along the coast of Asia, turns into the North Pacific to the Aleutian Islands, carrying with it trunks of camphor-trees and other indigenous productions, and edging the waves of the ocean with the pure indigo of its warm water. It was this current that the _Nautilus_ was to follow. I followed it with my eye; saw it lose itself in the vastness of the Pacific, and felt myself drawn with it, when Ned Land and Conseil appeared at the door of the saloon. My two brave companions remained petrified at the sight of the wonders spread before them. “Where are we, where are we?” exclaimed the Canadian. “In the museum at Quebec?” “My friends,” I answered, making a sign for them to enter, “you are not in Canada, but on board the _Nautilus_, fifty yards below the level of the sea.” “But, M. Aronnax,” said Ned Land, “can you tell me how many men there are on board? Ten, twenty, fifty, a hundred?” “I cannot answer you, Mr. Land; it is better to abandon for a time all idea of seizing the _Nautilus_ or escaping from it. This ship is a masterpiece of modern industry, and I should be sorry not to have seen it. Many people would accept the situation forced upon us, if only to move amongst such wonders. So be quiet and let us try and see what passes around us.” “See!” exclaimed the harpooner, “but we can see nothing in this iron prison! We are walking—we are sailing—blindly.” Ned Land had scarcely pronounced these words when all was suddenly darkness. The luminous ceiling was gone, and so rapidly that my eyes received a painful impression. We remained mute, not stirring, and not knowing what surprise awaited us, whether agreeable or disagreeable. A sliding noise was heard: one would have said that panels were working at the sides of the _Nautilus_. “It is the end of the end!” said Ned Land. Suddenly light broke at each side of the saloon, through two oblong openings. The liquid mass appeared vividly lit up by the electric gleam. Two crystal plates separated us from the sea. At first I trembled at the thought that this frail partition might break, but strong bands of copper bound them, giving an almost infinite power of resistance. The sea was distinctly visible for a mile all round the _Nautilus_. What a spectacle! What pen can describe it? Who could paint the effects of the light through those transparent sheets of water, and the softness of the successive graduations from the lower to the superior strata of the ocean?
