Then they will have begun to study more deeply into force disturbances, exhibitions of energy that are now known and called imponderable bodies (perhaps some of my statements will then even be verified), and to reflect over the connection of matter therewith. A few minds will then be capable of vaguely conceiving possibilities, which this paper will serve to foretell, for a true solution of the great problems of the ethereal unknown is herein suggested, the study of which will lead to a final elevation of humanity, such as I dare not prophesy." "Much of the paper is obscure to me," I said; "and there are occasional phrases and repetitions that appear to be interjected, possibly, with an object, and which are yet disconnected from the narrative proper." "That is true; the paper often contains statements that are emblematical, and which you can not understand, but yet such portions carry to others a hidden meaning. I am directed to speak to many persons besides yourself, and I can not meet those whom I address more directly than I do through this communication. These pages will serve to instruct many people--people whom you will never know, to whom I have brought messages that will in secret be read between the lines." "Why not give it to such persons?" "Because I am directed to bring it to you," he replied, "and you are required: "First, To seal the manuscript, and place it in the inner vault of your safe. "Second, To draw up a will, and provide in case of your death, that after the expiration of thirty years from this date, the seals are to be broken, and a limited edition published in book form, by one you select. "Third, An artist capable of grasping the conceptions will at the proper time be found, to whom the responsibility of illustrating the volume is to be entrusted, he receiving credit therefor. Only himself and yourself (or your selected agent) are to presume to select the subjects for illustration. "Fourth, In case you are in this city, upon the expiration of thirty years, you are to open the package and follow the directions given in the envelope therein." And he then placed on the manuscript a sealed envelope addressed to myself. "This I have promised already," I said. "Very well," he remarked, "I will bid you farewell." "Wait a moment; it is unjust to leave the narrative thus uncompleted. You have been promised a future in comparison with which the experiences you have undergone, and have related to me, were tame; you had just met on the edge of the inner circle that mysterious being concerning whom I am deeply interested, as I am in the continuation of your personal narrative, and you have evidently more to relate, for you must have passed into that Unknown Country. You claim to have done so, but you break the thread in the most attractive part by leaving the future to conjecture." "It must be so. This is a history of man on Earth, the continuation will be a history of man within the Unknown Country."
