As I sat thus absorbed, my attention was partially diverted by a slight tapping, as if upon the very table upon which my book was resting. Without raising my eyes from the page, I allowed my thoughts to wander, as I inquired within myself what could have produced the noise. Could it be that I was thus suddenly "developed as a medium," and that the spirit of some departed friend wished to communicate with me? I rejected the thought instantly, for I was no believer in modern necromancy. But no sooner had I mentally decided that this was not the true explanation than I began to feel my right hand tremble in an unnatural manner, and my fingers close against my will around a pencil which I had been loosely holding. Then suddenly, upon the paper on which I had been occasionally filling out the omitted links in Gauss's mathematical reasoning, my hand, against my will, legibly scrawled, "Copernicus,"—upon which a renewed tapping was heard upon the table. I sprang out of my chair, as one startled out of sleep, and looked about the room. My full consciousness of time and place returned, and I saw nothing unusual about my apartment; there were the books, the chairs, and even the table, standing in motionless silence as usual. I concluded that my late hours and excessive concentration on my studies had made me nervous, or else that I had had a dream. I closed the book and prepared to go to bed. Like school-boy whistling to keep his courage up, I began to talk aloud, saying: "I wish Copernicus would really come and carry me off to explore the solar system; I fancy that I could make a better report than Andrew Jackson Davis has done."
I tremble even now as I recall the instantaneous effect of those words. While I was still speaking, all earthly things vanished suddenly from my sight. There was no floor beneath me, no ceiling above, no walls around. There was even no earth below me, and no sky above. Look where I would, nothing was visible but my own body. My clothing shone with a pale blue light, by which I could peer into the surrounding darkness to the distance, as I should judge, of about twenty or thirty feet. I was apparently hanging, like a planet, in mid-ether, resting upon nothing. Horrible amazement seized me, as the conviction flashed through me like an electric shock that I must have lost my reason. In a few moments, however, this terror subsided; I felt certain that my thoughts were rational, and concluded that it was some affection of the optic nerve. But in a very few seconds I discovered by internal sensations that I was in motion, in a rapid, irregular, and accelerating motion. Awful horror again seized me; I screamed out a despairing cry for help, and fainted.
When I recovered from the swoon, I found myself lying on a grassy bank near a sea-shore, with strange trees waving over me. The sun was apparently an hour high. I was dressed as on the preceding evening, without a hat. The air was deliciously mild, the landscape before me lovely and grand. I said to myself: "This is a beautiful dream; it must be a dream." But it was too real, and I said, "Can it be that I am asleep?" I pinched my arms, I went to the sea and dipped my head in the waters,—'t was in vain; I could not awake myself, because I was already awake.
"No!" I replied, "you are not awake." Do you not remember that saying of Engel, that when men dream of asking whether they are awake, they always dream that they answer yes? But I said, I will apply two tests of my own which have often, when I was dreaming, convinced me that I was asleep and thus enabled me to awake. I gathered some pebbles and began to count them and lay them in heaps, and count them over again. There were no discrepancies between my counts; I was awake. Then I took out my pencil and memorandum-book to see whether I could solve an equation. But my hand was seized with trembling, and wrote without my assistance or guidance these words: "I, Copernicus, will comfort your friends. Be calm, be happy, you shall return and reap a peculiar glory. You, first of the inhabitants of Earth, have visited another planet while in the flesh. You are on an island in the tropical regions of Mars. I will take you home when you desire it,—only not now."
It would be in vain for me to attempt to recall and to describe the whirling tumult of thoughts and emotions which this message created. I sat down upon the grass, and for a time was incapable of deliberate thought or action. At length I arose and paced up and down the turf, staring around upon the changeless blue of the seaward horizon, the heaving swell of the ocean, the restless surf fretting against the shore, and the motionless hills that rose behind each other inland, and lured the eye to a distant group of mountains. The coloring of sea and land was wonderfully fine; both seemed formed of similar translucent purple; and despite the excited state of my feelings and the stupendous nature of the words which I had just seen written by my own pencil, I was impressed with a sense of grandeur and of beauty which presently filled me with faith and hope. I assured myself that the spirit to whom permission had been given thus to transport me from my home was as kind as he was powerful. He had set me down in a beautiful country, he had promised to return me home when I desired it,—"only not now";—by which I concluded that he wished me to think calmly over the question before asking to return. And why, I added, should I be in haste? Copernicus, if it be he, promises to comfort my parents,—the island looks fertile,—if I find no inhabitants, I can be a new Robinson Crusoe,—and when I have explored the island thoroughly, I will ask this spirit to carry me back to New York, where I shall publish my observations, and add a new chapter to our knowledge of the solar system.
I walked toward the mountains, among strange shrubs, and under strange trees. Some were in blossom, others laden with fruit, all in luxuriant foliage. As I walked on, the scenery became more and more charming; but I saw no signs of man, nor even of birds, nor beasts. Beautiful butterflies and other insects were abundant; in a little stream I saw minnows, and a fish elegantly striped with silver and gold; and as I followed up the brook, occasionally a frog, startled at my approach, leaped from the bank and dived into the water with a familiar cry. I wandered on until I judged it to be nearly noon, and, growing hungry, ventured to taste a fruit which looked more edible than any I had seen. To my delight I found it as delicious as a paw-paw. I dined on them heartily, and, sitting under the shade of the low trees from which I had gathered them, I fell into a reverie which ended in a sound sleep.
When I awoke it was night. I walked out of the little grove in which I was sheltered, that I might have a clearer view of the stars. I soon recognized the constellations with which I had been familiar for years, though in somewhat new positions. Conspicuous near, the horizon was the "Milk Dipper" of Sagittarius, and I instantly noticed, with a thrill of intense surprise, that the planet Mars was missing! When I had first awakened, and stepped out of the grove, I had only a dim remembrance in my mind of having rambled in the fields and fallen asleep on the grass; but this planet missing in the constellation Sagittarius recalled to me at once my miraculous position on the planet Mars. Here was a confirmation unexpected and irrefragable of the truth of what Copernicus had written by my hand. The excited whirl of thoughts and emotions thus revived banished sleep, and I walked back and forward under the grove, and out on the open turf, gazing again and again at the constellation in which, only two days before, I had from the Jersey City ferryboat seen the now missing planet. At length Sagittarius sank behind the mountains, and the Twins arose out of the sea. With new wonder and admiration I beheld in Castor's knee the steady lustre of a planet which I had not known before,—an overwhelming proof of the reality of my asserted position on the planet Mars. For as this new planet was exactly in the opposite pole of the point whence Mars was missing, what could it be but my native Earth seen as a planet from that planet which had now become my earth? You may imagine that this new vision excited me too much to allow sleep to overpower me again until nearly daybreak.
When I awoke, the sun was far above the waves. I breakfasted upon my newly tasted fruit, and resumed my journey toward the mountains in the west. An hour's walk brought me to the spot where I first saw the inhabitants of the island. I shall never forget a single feature of that landscape. The mingled delight at seeing them, and astonishment after looking a few moments at them, have photographed the whole surrounding scene to its minutest details indelibly upon my memory. I had ascended a little eminence in the principal valley of a brook, (which
