the frigate hors de combat; she will not have any difficulty in getting repaired at the next port."
"Ah, Commander! your Nautilus is certainly a marvellous boat."
"Yes, Professor; and I love it as if it were part of myself. If danger threatens one of your vessels on the ocean, the first impression is the feeling of an abyss above and below. On the Nautilus men's hearts never fail them. No defects to be afraid of, for the double shell is as firm as iron; no rigging to attend to; no sails for the wind to carry away; no boilers to burst; no fire to fear, for the vessel is made of iron, not of wood; no coal to run short, for electricity is the only mechanical agent; no collision to fear, for it alone swims in deep water; no tempest to brave, for when it dives below the water it reaches absolute tranquillity. There, sir! that is the perfection of vessels! And if it is true that the engineer has more confidence in the vessel than the builder, and the builder than the captain himself, you understand the trust I repose in my Nautilus; for I am at once captain, builder, and engineer."
"But how could you construct this wonderful Nautilus in secret?"
"Each separate portion, M. Aronnax, was brought from different parts of the globe."
"But these parts had to be put together and arranged?"
"Professor, I had set up my workshops upon a desert island in the ocean. There my workmen, that is to say, the brave men that I instructed and educated, and myself have put together our Nautilus. Then, when the work was finished, fire destroyed all trace of our proceedings on this island, that I could have jumped over if I had liked."
"Then the cost of this vessel is great?"
"M. Aronnax, an iron vessel costs L145 per ton. Now the Nautilus weighed 1,500. It came therefore to L67,500, and L80,000 more for fitting it up, and about L200,000, with the works of art and the collections it contains."
"One last question, Captain Nemo."
"Ask it, Professor."
"You are rich?"
"Immensely rich, sir; and I could, without missing it, pay the national debt of France."
I stared at the singular person who spoke thus. Was he playing upon my credulity? The future would decide that.
CHAPTER XIII
THE BLACK RIVER
The portion of the terrestrial globe which is covered by water is estimated at upwards of eighty millions of acres. This fluid mass comprises two billions two hundred and fifty millions of cubic miles, forming a spherical body of a diameter of sixty leagues, the weight of which would be three quintillions of tons. To comprehend the meaning of these figures, it is necessary to observe that a quintillion is to a billion as a billion is to unity; in other words, there are as many billions in a quintillion as there are units in a billion. This mass of fluid is equal to about the quantity of water which would be discharged by all the rivers of the earth in forty thousand years.
During the geological epochs the ocean originally prevailed everywhere. Then by degrees, in the silurian period, the tops of the mountains began to appear, the islands emerged, then disappeared in partial deluges, reappeared, became settled, formed continents, till at length the earth became geographically arranged, as we see in the present day. The solid had wrested from the liquid thirty-seven million six hundred and fifty-seven square miles, equal to twelve billions nine hundred and sixty millions of acres.
The shape of continents allows us to divide the waters into five great portions: the Arctic or Frozen Ocean, the Antarctic, or Frozen Ocean, the Indian, the Atlantic, and the Pacific Oceans.
The Pacific Ocean extends from north to south between the two Polar Circles, and from east to west between Asia and America, over an extent of 145 degrees of longitude. It is the quietest of seas; its currents are broad and slow, it has medium tides, and abundant rain. Such was the ocean that my fate destined me first to travel over under these strange conditions.
"Sir," said Captain Nemo, "we will, if you please, take our bearings and fix the starting-point of this voyage. It is a quarter to twelve; I will go up again to the surface."
The Captain pressed an electric clock three times. The pumps began to drive the water from the tanks; the needle of the manometer marked by a different pressure the ascent of the Nautilus, then it stopped.
"We have arrived," said the Captain.
I went to the central staircase which opened on to the platform, clambered up the iron steps, and found myself on the upper part of the Nautilus.
The platform was only three feet out of water. The front and back of the Nautilus was of that spindle-shape which caused it justly to be compared to a cigar. I noticed that its iron plates, slightly overlaying each other, resembled the shell which clothes the bodies of our large terrestrial reptiles. It explained to me how natural it was, in spite of all glasses, that this boat should have been taken for a marine animal.
Toward the middle of the platform the longboat, half buried in the hull of the vessel, formed a slight excrescence. Fore and aft rose two cages of medium height with inclined sides, and partly closed by thick lenticular glasses; one destined for the steersman who directed the Nautilus, the other containing a brilliant lantern to give light on the road.
The sea was beautiful, the sky pure. Scarcely could the long vehicle feel the broad undulations of the ocean. A light breeze from the east rippled the surface of the waters. The horizon, free from fog, made observation easy. Nothing was in sight. Not a quicksand, not an island. A vast desert.
Captain Nemo, by the help of his sextant, took the altitude of the sun, which ought also to give the latitude. He waited for some moments till its disc touched the horizon. Whilst taking observations not a muscle moved, the instrument could not have been more motionless in a hand of marble.
"Twelve o'clock, sir," said he. "When you like----"
I cast a last look upon the sea, slightly yellowed by the Japanese coast, and descended to the saloon.
"And now, sir, I leave you to your studies," added the Captain; "our course is E.N.E., our depth is twenty-six fathoms. Here are maps on a large scale by which you may follow it. The saloon is at your disposal, and, with your permission, I will retire." Captain Nemo bowed, and I remained alone, lost in thoughts all bearing on the commander of the Nautilus.
For a whole hour was I deep in these reflections, seeking to pierce this mystery so interesting to me. Then my eyes fell upon the vast planisphere spread upon the table, and I placed my finger on the very spot where the given latitude and longitude crossed.
The sea has its large rivers like the continents. They are special currents known by their temperature and their colour. The most remarkable of these is known by the name of the Gulf Stream. Science has decided on the globe the direction of five principal currents: one in the North Atlantic, a second in the South, a third in the North Pacific, a fourth in the South, and a fifth in the Southern Indian Ocean. It is even probable that a sixth current existed at one time or another in the Northern Indian Ocean, when the Caspian and Aral Seas formed but one vast sheet of water.
At this point indicated on the planisphere one of these currents was rolling, the Kuro-Scivo of the Japanese, the Black
