Southward and Westward, the moon was sinking rapidly.  The night had come, already.  A minute it seemed, and the moon fell those remaining fathoms of dark sky.  Another minute, or so, and the Eastward sky glowed with the coming dawn.  The sun leapt upon me with a frightening abruptness, and soared ever more swiftly toward the zenith.  Then, suddenly, a fresh thing came to my sight.  A black thundercloud rushed up out of the South, and seemed to leap all the arc of the sky, in a single instant.  As it came, I saw that its advancing edge flapped, like a monstrous black cloth in the heaven, twirling and undulating rapidly, with a horrid suggestiveness.  In an instant, all the air was full of rain, and a hundred lightning flashes seemed to flood downward, as it were in one great shower.  In the same second of time, the world-noise was drowned in the roar of the wind, and then my ears ached, under the stunning impact of the thunder.

And, in the midst of this storm, the night came; and then, within the space of another minute, the storm had passed, and there was only the constant ‘blur’ of the world-noise on my hearing.  Overhead, the stars were sliding quickly Westward; and something, mayhaps the particular speed to which they had attained, brought home to me, for the first time, a keen realization of the knowledge that it was the world that revolved.  I seemed to see, suddenly, the world—­a vast, dark mass—­revolving visibly against the stars.

The dawn and the sun seemed to come together, so greatly had the speed of the world-revolution increased.  The sun drove up, in one long, steady curve; passed its highest point, and swept down into the Western sky, and disappeared.  I was scarcely conscious of evening, so brief was it.  Then I was watching the flying constellations, and the Westward hastening moon.  In but a space of seconds, so it seemed, it was sliding swiftly downward through the night-blue, and then was gone.  And, almost directly, came the morning.

And now there seemed to come a strange acceleration.  The sun made one clean, clear sweep through the sky, and disappeared behind the Westward horizon, and the night came and went with a like haste.

As the succeeding day, opened and closed upon the world, I was aware of a sweat of snow, suddenly upon the earth.  The night came, and, almost immediately, the day.  In the brief leap of the sun, I saw that the snow had vanished; and then, once more, it was night.

Thus matters were; and, even after the many incredible things that I have seen, I experienced all the time a most profound awe.  To see the sun rise and set, within a space of time to be measured by seconds; to watch (after a little) the moon leap—­a pale, and ever growing orb—­up into the night sky, and glide, with a strange swiftness, through the vast arc of blue; and, presently, to see the sun follow, springing out of the Eastern sky, as though in chase; and then again the night, with the swift and ghostly passing of starry constellations, was all too much to view believingly.  Yet, so it was—­the day slipping from dawn to dusk, and the night sliding swiftly into day, ever rapidly and more rapidly.
