The following night and day were passed like their predecessors. Another night came, and we were over the eastern bound of the State of California. A few hours more, without accident, would terminate our remarkable voyage, and set us down in the city of San Francisco. All of us were brimming high with hope. Though we did not anticipate reaching the station before one or two o'clock in the morning, and probably should not disembark before dawn, we were loath to retire to rest. It was near midnight before all of us were in our berths.

But when at length there, I found it impossible to sleep. The excitement attendant on the beginning of the trip seemed to have returned on me with a double force. I listened for some sound to relieve the awful stillness which, like the wing of Death, seemed to have settled over the "Flying Cloud"; but there was no soughing of the wind, as at sea, and no noise to be heard, save the monotonous movement of the engine and the paddle-wheels; and this, so evenly did they play, was rather a motion than a sound.

This period of restlessness was succeeded by one of strange bewilderment, which might have been sleep, or might not Rapidly changing scenes and fantastic figures, some of them beautiful and some horrible, flitted before me like a dissolving panorama. A band, as though of steel wire, seemed to encircle my brain, and to compress it closer and closer; and the spine, for its whole length, felt as though subjected to a like crushing pressure.

How long this state of hallucination continued I have no means of knowing. From it, by a great effort, I suddenly aroused myself, and returned to my proper senses. Where I was, and all the extraordinary events of the last few days, were clear in my recollection. But I was weighed down with weakness, and found, on attempting to speak, that I had no voice.

Suspecting that I had been stricken by some terrible disease, I attempted to rise; and, loath to disturb any of my fellow-travellers, undertook to crawl out upon the upper deck. This, after a good deal of effort, I accomplished. Lying, therefore,—I could not stand,—I prayed for a breath of air to relieve my hot and oppressed brow; but in vain. The atmosphere seemed gone. Chill and dark, the heavens spread out above me without a twinkle or a smile. The full-moon was there, and there was no cloud or haze to obscure her light; but she did not shine. Her white, rayless face was a mockery to the night. The same was true of the stars. The dazzling canopy was faded out, and Cygnus and the Great Bear were subdued to pallid points, like patches of white-gray paper stuck upon a wall.

Floating by the side of the "Flying Cloud," and nearly of her size, I discovered a dark, irregular object, and dragged myself to the edge of the deck to investigate it more closely. The two came together, but without damage or friction. They touched and parted, like substances nearly at rest in still water. I put out my hand on the strange visitor, and received a pretty severe shock, as though I had been subjected to the action of an electric battery. At the same time, a light, bluish flame ran over its surface, showing me more accurately its form and dimensions. To the touch, it was solid and cold, like iron or granite. I pressed upon it, and it yielded like a floating dish. I tried to break off a fragment, but was unable to separate so much as a scale.

A moment's reflection convinced me of the nature of this apparent island in the air. It was an immense aërolite; and with this conviction came the solution of my own painful state. We had unconsciously passed beyond the controlling power of the earth's gravitation, into that region of the upper atmosphere, where, science informs us, these meteoric stones float in equilibrium, until some accidental impulse throws them from their balance, when they are precipitated to the surface of the earth. I must be dying for lack of air. And the man at the helm, where was he? He must have fallen asleep, and left our vessel to her own buoyant fancies. And my companions! Bonflon! De Aëry! All ere this might have perished, and the "Flying Cloud," aside from myself, be bearing into these upper altitudes nothing but a load of death.

Terror-struck, I dragged myself, with all the speed I could accomplish, to the stern. There sat the helmsman at his post, but asleep or insensible. I shook him, but he gave no signs of life. I shouted with what little strength I had, but in vain.

"Wake up! wake up!" I cried, "or we are lost!"

At length he opened his eyes, but did not move.
