The next day,the 20th of February,Iawoke very late:the fatigues of the previous night had prolonged my sleep until eleven o'clock.Idressed quickly,and hastened to find the course the Nautilus was taking.
The instruments showed it to be still toward the south,with a speed of twenty miles an hour and a depth of fifty fathoms.
The species of fishes here did not differ much from those already noticed.
There were rays of giant size,five yards long,and endowed with great muscular strength,which enabled them to shoot above the waves;sharks of many kinds;amongst others,one fifteen feet long,with triangular sharp teeth,and whose transparency rendered it almost invisible in the water.
Amongst bony fish Conseil noticed some about three yards long,armed at the upper jaw with a piercing sword;other bright-coloured creatures,known in the time of Aristotle by the name of the sea-dragon,which are dangerous to capture on account of the spikes on their back.
About four o'clock,the soil,generally composed of a thick mud mixed with petrified wood,changed by degrees,and it became more stony,and seemed strewn with conglomerate and pieces of basalt,with a sprinkling of lava.
Ithought that a mountainous region was succeeding the long plains;and accordingly,after a few evolutions of the Nautilus,Isaw the southerly horizon blocked by a high wall which seemed to close all exit.
Its summit evidently passed the level of the ocean.It must be a continent,or at least an island--one of the Canaries,or of the Cape Verde Islands.
The bearings not being yet taken,perhaps designedly,Iwas ignorant of our exact position.In any case,such a wall seemed to me to mark the limits of that Atlantis,of which we had in reality passed over only the smallest part.
Much longer should Ihave remained at the window admiring the beauties of sea and sky,but the panels closed.At this moment the Nautilus arrived at the side of this high,perpendicular wall.
What it would do,Icould not guess.Ireturned to my room;it no longer moved.Ilaid myself down with the full intention of waking after a few hours'sleep;but it was eight o'clock the next day when Ientered the saloon.Ilooked at the manometer.
It told me that the Nautilus was floating on the surface of the ocean.
Besides,Iheard steps on the platform.Iwent to the panel.
It was open;but,instead of broad daylight,as Iexpected,Iwas surrounded by profound darkness.Where were we?
Was Imistaken?Was it still night?No;not a star was shining and night has not that utter darkness.
Iknew not what to think,when a voice near me said:
"Is that you,Professor?"
"Ah!Captain,"Ianswered,"where are we?"
"Underground,sir."
"Underground!"Iexclaimed."And the Nautilus floating still?""It always floats."
"But Ido not understand."
"Wait a few minutes,our lantern will be lit,and,if you like light places,you will be satisfied."Istood on the platform and waited.The darkness was so complete that Icould not even see Captain Nemo;but,looking to the zenith,exactly above my head,Iseemed to catch an undecided gleam,a kind of twilight filling a circular hole.At this instant the lantern was lit,and its vividness dispelled the faint light.
Iclosed my dazzled eyes for an instant,and then looked again.
The Nautilus was stationary,floating near a mountain which formed a sort of quay.The lake,then,supporting it was a lake imprisoned by a circle of walls,measuring two miles in diameter and six in circumference.Its level (the manometer showed)could only be the same as the outside level,for there must necessarily be a communication between the lake and the sea.
The high partitions,leaning forward on their base,grew into a vaulted roof bearing the shape of an immense funnel turned upside down,the height being about five or six hundred yards.
At the summit was a circular orifice,by which Ihad caught the slight gleam of light,evidently daylight.
"Where are we?"Iasked.
"In the very heart of an extinct volcano,the interior of which has been invaded by the sea,after some great convulsion of the earth.
Whilst you were sleeping,Professor,the Nautilus penetrated to this lagoon by a natural canal,which opens about ten yards beneath the surface of the ocean.This is its harbour of refuge,a sure,commodious,and mysterious one,sheltered from all gales.
Show me,if you can,on the coasts of any of your continents or islands,a road which can give such perfect refuge from all storms.""Certainly,"Ireplied,"you are in safety here,Captain Nemo.
Who could reach you in the heart of a volcano?But did Inot see an opening at its summit?""Yes;its crater,formerly filled with lava,vapour,and flames,and which now gives entrance to the life-giving air we breathe.""But what is this volcanic mountain?"
"It belongs to one of the numerous islands with which this sea is strewn--to vessels a simple sandbank--to us an immense cavern.
Chance led me to discover it,and chance served me well.""But of what use is this refuge,Captain?The Nautilus wants no port.""No,sir;but it wants electricity to make it move,and the wherewithal to make the electricity--sodium to feed the elements,coal from which to get the sodium,and a coal-mine to supply the coal.
And exactly on this spot the sea covers entire forests embedded during the geological periods,now mineralised and transformed into coal;for me they are an inexhaustible mine."
"Your men follow the trade of miners here,then,Captain?""Exactly so.These mines extend under the waves like the mines of Newcastle.
Here,in their diving-dresses,pick axe and shovel in hand,my men extract the coal,which Ido not even ask from the mines of the earth.
