Twenty Thousand Leagues Under the Sea. Jules Verne

      Captain Nemo was silent, and seemed lost in a profound reverie. I contemplated him with deep interest, analysing in silence the strange expression of his countenance. Leaning on his elbow against an angle of a costly mosaic table, he no longer saw me,—he had forgotten my presence.

      I did not disturb this reverie, and continued my observation of the curiosities which enriched this drawing-room.

      Under elegant glass cases, fixed by copper rivets, were classed and labelled the most precious productions of the sea which had ever been presented to the eye of a naturalist. My delight as a professor may be conceived.

      The division containing the zoophytes presented the most curious specimens of the two groups of polypi and echinodermes. In the first group, the tubipores, were gorgones arranged like a fan, soft sponges of Syria, ises of the Moluccas, pennatules, an admirable virgularia of the Norwegian seas, variegated unbellulairae, alcyonariae, a whole series of madrepores, which my master Milne Edwards has so cleverly classified, amongst which I remarked some wonderful flabellinae oculinae of the Island of Bourbon, the "Neptune's car" of the Antilles, superb varieties of corals—in short, every species of those curious polypi of which entire islands are formed, which will one day become continents. Of the echinodermes, remarkable for their coating of spines, asteri, sea-stars, pantacrinae, comatules, asterophons, echini, holothuri, etc., represented individually a complete collection of this group.

      A somewhat nervous conchyliologist would certainly have fainted before other more numerous cases, in which were classified the specimens of molluscs. It was a collection of inestimable value, which time fails me to describe minutely. Amongst these specimens I will quote from memory only the elegant royal hammer-fish of the Indian Ocean, whose regular white spots stood out brightly on a red and brown ground, an imperial spondyle, bright-coloured, bristling with spines, a rare specimen in the European museums—(I estimated its value at not less than L1000); a common hammer-fish of the seas of New Holland, which is only procured with difficulty; exotic buccardia of Senegal; fragile white bivalve shells, which a breath might shatter like a soap-bubble; several varieties of the aspirgillum of Java, a kind of calcareous tube, edged with leafy folds, and much debated by amateurs; a whole series of trochi, some a greenish-yellow, found in the American seas, others a reddish-brown, natives of Australian waters; others from the Gulf of Mexico, remarkable for their imbricated shell; stellari found in the Southern Seas; and last, the rarest of all, the magnificent spur of New Zealand; and every description of delicate and fragile shells to which science has given appropriate names.

      Apart, in separate compartments, were spread out chaplets of pearls of the greatest beauty, which reflected the electric light in little sparks of fire; pink pearls, torn from the pinna-marina of the Red Sea; green pearls of the haliotyde iris; yellow, blue and black pearls, the curious productions of the divers molluscs of every ocean, and certain mussels of the water-courses of the North; lastly, several specimens of inestimable value which had been gathered from the rarest pintadines. Some of these pearls were larger than a pigeon's egg, and were worth as much, and more than that which the traveller Tavernier sold to the Shah of Persia for three millions, and surpassed the one in the possession of the Imaum of Muscat, which I had believed to be unrivalled in the world.

      Therefore, to estimate the value of this collection was simply impossible. Captain Nemo must have expended millions in the acquirement of these various specimens, and I was thinking what source he could have drawn from, to have been able thus to gratify his fancy for collecting, when I was interrupted by these words:

      "You are examining my shells, Professor? Unquestionably they must be interesting to a naturalist; but for me they have a far greater charm, for I have collected them all with my own hand, and there is not a sea on the face of the globe which has escaped my researches."

      "I can understand, Captain, the delight of wandering about in the midst of such riches. You are one of those who have collected their treasures themselves. No museum in Europe possesses such a collection of the produce of the ocean. But if I exhaust all my admiration upon it, I shall have none left for the vessel which carries it. I do not wish to pry into your secrets: but I must confess that this Nautilus, with the motive power which is confined in it, the contrivances which enable it to be worked, the powerful agent which propels it, all excite my curiosity to the highest pitch. I see suspended on the walls of this room instruments of whose use I am ignorant."

      "You will find these same instruments in my own room, Professor, where I shall have much pleasure in explaining their use to you. But first come and inspect the cabin which is set apart for your own use. You must see how you will be accommodated on board the Nautilus."

      I followed Captain Nemo who, by one of the doors opening from each panel of the drawing-room, regained the waist. He conducted me towards the bow, and there I found, not a cabin, but an elegant room, with a bed, dressing-table, and several other pieces of excellent furniture.

      I could only thank my host.

      "Your room adjoins mine," said he, opening a door, "and mine opens into the drawing-room that we have just quitted."

      I entered the Captain's room: it had a severe, almost a monkish aspect. A small iron bedstead, a table, some articles for the toilet; the whole lighted by a skylight. No comforts, the strictest necessaries only.

      Captain Nemo pointed to a seat.

      "Be so good as to sit down," he said. I seated myself, and he began thus:

      Chapter XI

      All By Electricity

      "Sir," said Captain Nemo, showing me the instruments hanging on the walls of his room, "here are the contrivances required for the navigation of the Nautilus. Here, as in the drawing-room, I have them always under my eyes, and they indicate my position and exact direction in the middle of the ocean. Some are known to you, such as the thermometer, which gives the internal temperature of the Nautilus; the barometer, which indicates the weight of the air and foretells the changes of the weather; the hygrometer, which marks the dryness of the atmosphere; the storm-glass, the contents of which, by decomposing, announce the approach of tempests; the compass, which guides my course; the sextant, which shows the latitude by the altitude of the sun; chronometers, by which I calculate the longitude; and glasses for day and night, which I use to examine the points of the horizon, when the Nautilus rises to the surface of the waves."

      "These are the usual nautical instruments," I replied, "and I know the use of them. But these others, no doubt, answer to the particular requirements of the Nautilus. This dial with movable needle is a manometer, is it not?"

      "It is actually a manometer. But by communication with the water, whose external pressure it indicates, it gives our depth at the same time."

      "And these other instruments, the use of which I cannot guess?"

      "Here, Professor, I ought to give you some explanations. Will you be kind enough to listen to me?"

      He was silent for a few moments, then he said:

      "There is a powerful agent, obedient, rapid, easy, which conforms to every use, and reigns supreme on board my vessel. Everything is done by means of it. It lights, warms it, and is the soul of my mechanical apparatus. This agent is electricity."

      "Electricity?" I cried in surprise.

      "Yes, sir."

      "Nevertheless, Captain, you possess an extreme rapidity of movement, which does not agree well with the power of electricity. Until now, its dynamic force has remained under restraint, and has only been able to produce a small amount of power."

      "Professor," said Captain Nemo, "my electricity is not everybody's. You know what sea-water is composed of. In a thousand grammes are found 96 1/2 per cent. of water, and about 2 2/3 per cent. of chloride of sodium; then, in a smaller quantity, chlorides of magnesium and of potassium, bromide of magnesium, sulphate of magnesia, sulphate and carbonate of lime. You see, then, that chloride of sodium forms a large part of it. So it is this sodium that I extract from the sea-water, and of which I compose my ingredients. I owe all to the ocean; it produces electricity, and electricity gives heat, light, motion, and, in a word, life to the Nautilus."
