voices, and evidently the person at the other end was as anxious as I to make himself understood and to understand the nature of his unknown correspondent’s speech.
“You may imagine what a heartbreaking business it was, with no common vocabulary, invisible to one another, and living possibly in conditions widely different, to make our meaning clear to one another. We made a start with the cardinal numbers, and after a week’s interchange we had mastered these. I was then struck with the idea of pouring a glass of water from a tumbler near to my microphone, and using the word ‘water.’ In half-an-hour I heard the sound of falling water from the other end and the equivalent word, which will be found in the vocabulary. I then clapped my hands together, and used the word ‘hand.’ With these little illustrations, which took a great deal of time, began the formation of the dictionary. In the Neo language there are practically no verbs and few adjectives. Very much is indicated by a certain inflexion of voice; even the tenses are similarly expressed; and yet, in spite of this, the Neothians to whom I spoke had no very great difficulty, once I had learnt the art of the inflexion, in supplying the English equivalent.
“All the time I was searching the heavens in the vain endeavour to discover the exact location of this world, which was, from the description I had, exactly the same size as ours, and therefore should have been visible. I had maps of the southern hemispheres, reports from the astronomers of Capetown and Brisbane, but they could offer me no assistance. It was certain that there was in the heavens no visible planetary body as big as Neo.
“The chief difficulty I had lay in the fact that the voices invariably came from the direction of the sun; and it was as certain as anything could be that life could not exist on that great golden mass. Notwithstanding this, unless my mirror was turned to the sun, I received no message whatever; and even in the middle of the night, when I was communicating with Neo, it was necessary that I should follow, the sun’s course.
“Then came the great eclipse, and, as you know, I went to the South Sea Islands to make observations. It was our good fortune to have fine weather, and at the moment of total eclipse I took several particularly excellent photographs, some of which you will find in the portfolio marked ‘L.’ In these and photographs taken by other astronomers, you will see, if you make a careful observation, close to the corona, a tiny speck of light, which at first I thought was my world, but which afterwards I discovered was a dead mass of material upon which it was impossible for life to exist.
“One night, when I was turning over the matter in my mind, and examining each photograph in the study of my house on the Thames, the solution flashed on me. This tiny speck, which was not a star, and was certainly not Vulcan, was the satellite of another world, and that world was moving on the same orbit as our own earth, following exactly the same course, but being, as it was, immediately opposite to us behind the sun, was never visible! On whatever part of the ellipse we might be, the sun hid our sister world from us, and that was why the voice apparently came from the sun, for it was through the solar centre that the waves must pass. Two earths chasing one another along the same path, never overtaking, never being overtaken, balancing one another perfectly! It was a stupendous thought!
“I conveyed to my unknown friend, who called himself Colson, though I am under the impression that that was due to a misconception on his part as to what Colson meant — he probably thought that ‘Colson’ was the English word for ‘scientist’ — and I asked him to make observations. These he sent to me after a few days, confirming my theory. It was after we had begun to talk a little more freely, and my acquaintance with the language had increased so that I could express myself clearly, that it occurred to me there was an extraordinary similarity both in our lives and our environment. And this is the part in my narrative which you will find difficult to believe — I discovered that these two worlds were not only geographically exact, but that the incidents of life ran along on parallel lines. There were great wars in Neo, great disasters, which were invariably duplicated on our earth, generally from two to three days before or after they had happened in this new world. Nor was it only the convulsions of nature that were so faithfully reproduced. Men and women were doing in that world exactly as we were doing in ours. There were Stock Exchanges and street cars, railways, aeroplanes, as though twin worlds had produced twin identities; twin inspirations.
“I learnt this first when my friend told me that he had been seeking me for some time. He said that he had had a broken knee some five years ago, and during his enforced leisure he had pointed out the possibility of his having another identity. He said he was frequently feeling that the person he met for the first time was one in reality whom he had seen before; and he was conscious that the thing he did to-day, he had done a week before. That is a sensation which I also have had, and which every human being has experienced.
“But to go back to the story of his having been laid up with a broken knee. He had no sooner told me this than I realised that I also had had a broken knee — I had a spill on my motor-bicycle — and that I had spent the hours of my leisure pondering the possibility of there being another inhabited planet! There is a vulgar expression, frequently met with amongst neurotic people, that they have twin souls. In very truth this man was my twin soul: was me, had lived my life, thought my thoughts, performed every action which I performed. The discovery staggered me, and I began to fear for my reason; so I went to London and consulted an eminent Harley Street specialist. He assured me that I was perfectly normal and sane, and offered me the conventional advice that I should go away for a holiday.
“Then one day my astral friend, Colson, incidentally mentioned that there was great excitement in his town because a man had bought some steel stock which had since risen considerably in price — he mentioned the name — and, glancing through a newspaper, I saw the name of a stock which sounded very similar to that of which he had told me. Moreover, the price was very much as he had mentioned it; and the wild idea occurred to me that if happenings were actually duplicated, I might possibly benefit by my knowledge. With great trepidation I invested the whole of my savings, which were not very considerable, in these shares, and a few days later had the gratification of selling out at a colossal profit. I explained to my friend at the next opportunity what I had done, and he was considerably amused, and afterwards took an almost childish delight in advising me as to the violent fluctuations in various stocks. For years I have bought and sold with considerable benefit to myself. Not only that, but I have been able to warn Governments of impending disasters. I informed the Turkish Government of the great Armenian earthquake, and warned the Lamborn Shipping Company of the terrible disaster which overtook one of their largest liners — though I was not thanked for my pains.
“After this had been going on for some years, I was prepared to learn that my friend had incurred the enmity of a rich man, whom he called Frez on his side, and that this had been brought about unwittingly through me. For this is a curious fact: not everything on this new world is three days in advance of ours. Often it happened that the earth was in advance, and I was able, in our exchanges, to tell him things that were happening here which had not yet occurred in Neo, with the result that he followed my example, and in the space of a year had become a very rich man.
“Colson, as I called him, had a servant, whose name I have never learnt; he was called the equivalent to ‘helper,’ and I guess, rather than know, that he is a much younger man than my double, for he said that he had been to school as a pupil of Colson’s. He too learnt quickly; and if there is any difference in the two worlds, it is a keener intelligence: they are more receptive, quicker to grasp essentials.
“There are necessarily certain differences in their methods of government, but these differences are not vital. In Neo men are taught the use of arms, and receive their guerdon of citizenship (which I presume is the vote) only on production of a certificate of proficiency. But in the main their lives run parallel with ours. The very character of their streets, their systems of transportation, even their prison system, are replicas of those on this earth. The main difference, of course, is that their one language is universal. I intend at a later date writing at greater length on the institutions of Neo, but for the moment
