Friday, August 21st. This morning the magnificent geyser had wholly disappeared. The wind had freshened up, and we were fast leaving the neighborhood of Henry's Island. Even the roaring sound of the mighty column was lost to the ear.  
The weather, if, under the circumstances, we may use such an expression, is about to change very suddenly. The atmosphere is being gradually loaded with vapors, which carry with them the electricity formed by the constant evaporation of the saline waters; the clouds are slowly but sensibly falling towards the sea, and are assuming a dark-olive texture; the electric rays can scarcely pierce through the opaque curtain which has fallen like a drop scene before this wondrous theater, on the stage of which another and terrible drama is soon to be enacted. This time it is no fight of animals; it is the fearful battle of the elements.
 
I feel that I am very peculiarly influenced, as all creatures are on land when a deluge is about to take place.
 
The cumuli, a perfectly oval kind of cloud, piled upon the south, presented a most awful and sinister appearance, with the pitiless aspect often seen before a storm. The air is extremely heavy; the sea is comparatively calm.
 
In the distance, the clouds have assumed the appearance of enormous balls of cotton, or rather pods, piled one above the other in picturesque confusion. By degrees, they appear to swell out, break, and gain in number what they lose in grandeur; their heaviness is so great that they are unable to lift themselves from the horizon; but under the influence of the upper currents of air, they are gradually broken up, become much darker, and then present the appearance of one single layer of a formidable character; now and then a lighter cloud, still lit up from above, rebounds upon this grey carpet, and is lost in the opaque mass.
 
There can be no doubt that the entire atmosphere is saturated with electric fluid; I am myself wholly impregnated; my hairs literally stand on end as if under the influence of a galvanic battery. If one of my companions ventured to touch me, I think he would receive rather a violent and unpleasant shock.
 
About ten o'clock in the morning, the symptoms of the storm became more thorough and decisive; the wind appeared to soften down as if to take breath for a renewed attack; the vast funereal pall above us looked like a huge bag—like the cave of AEolus, in which the storm was collecting its forces for the attack.
 
I tried all I could not to believe in the menacing signs of the sky, and yet I could not avoid saying, as it were involuntarily:
 
"I believe we are going to have bad weather."
 
The Professor made me no answer. He was in a horrible, in a detestable humor—to see the ocean stretching interminably before his eyes. On hearing my words he simply shrugged his shoulders.
 
"We shall have a tremendous storm," I said again, pointing to the horizon. "These clouds are falling lower and lower upon the sea, as if to crush it."
 
A great silence prevailed. The wind wholly ceased. Nature assumed a dead calm, and ceased to breathe. Upon the mast, where I noticed a sort of slight ignis fatuus, the sail hangs in loose heavy folds. The raft is motionless in the midst of a dark heavy sea—without undulation, without motion. It is as still as glass. But as we are making no progress, what is the use of keeping up the sail, which may be the cause of our perdition if the tempest should suddenly strike us without warning.
 
"Let us lower the sail," I said, "it is only an act of common prudence."
 
"No—no," cried my uncle, in an exasperated tone, "a hundred times, no. Let the wind strike us and do its worst, let the storm sweep us away where it will—only let me see the glimmer of some coast—of some rocky cliffs, even if they dash our raft into a thousand pieces. No! keep up the sail—no matter what happens."
 
These words were scarcely uttered when the southern horizon underwent a sudden and violent change. The long accumulated vapors were resolved into water, and the air required to fill up the void produced became a wild and raging tempest.
 
It came from the most distant corners of the mighty cavern. It raged from every point of the compass. It roared; it yelled; it shrieked with glee as of demons let loose. The darkness increased and became indeed darkness visible.
 
The raft rose and fell with the storm, and bounded over the waves. My uncle was cast headlong upon the deck. I with great difficulty dragged myself towards him. He was holding on with might and main to the end of a cable, and appeared to gaze with pleasure and delight at the spectacle of the unchained elements.
 
Hans never moved a muscle. His long hair driven hither and thither by the tempest and scattered wildly over his motionless face, gave him a most extraordinary appearance—for every single hair was illuminated by little sparkling sprigs.
 
His countenance presents the extraordinary appearance of an antediluvian man, a true contemporary of the Megatherium.
 
Still the mast holds good against the storm. The sail spreads out and fills like a soap bubble about to burst. The raft rushes on at a pace impossible to estimate, but still less swiftly than the body of water displaced beneath it, the rapidity of which may be seen by the lines which fly right and left in the wake.
 
"The sail, the sail!" I cried, making a trumpet of my hands, and then endeavoring to lower it.
 
"Let it alone!" said my uncle, more exasperated than ever.
 
"Nej," said Hans, gently shaking his head.
 
Nevertheless, the rain formed a roaring cataract before this horizon of which we were in search, and to which we were rushing like madmen.
 
But before this wilderness of waters reached us, the mighty veil of cloud was torn in twain; the sea began to foam wildly; and the electricity, produced by some vast and extraordinary chemical action in the upper layer of cloud, is brought into play. To the fearful claps of thunder are added dazzling flashes of lightning, such as I had never seen. The flashes crossed one another, hurled from every side; while the thunder came pealing like an echo. The mass of vapor becomes incandescent; the hailstones which strike the metal of our boots and our weapons are actually luminous; the waves as they rise appear to be fire-eating monsters, beneath which seethes an intense fire, their crests surmounted by combs of flame.
 
My eyes are dazzled, blinded by the intensity of ligh............
