To all who may be concerned in an endeavor to acquire information relating to affairs beyond the range of physical vision we offer for consideration what may be regarded as an incredible narrative of journeys to, and explorations of the Planet known as Mars, and we entreat that you shall not pass unfriendly judgment upon that which may impress you as a merely imaginative composition, but which, in all sincerity, is a statement of facts. Desiring to, as far as practicable, simplify the relation of this absolutely truthful narrative, of a not unexampled undertaking, I, and others of the Evon-thia, have thought it well to present it in colloquial form, as being more realistic than any other mode of expression, and also we have thought it well, that only a limited number of our numerous Band shall present themselves as actors, in what may appear a fanciful drama. We are aware that we might offer certain special pleadings, which, in many minds, would induce favorable consideration of the unvarnished relation of our varied experiences, but we prefer to leave to the more or less enlightened seekers after truth, such verdict as their inner perceptions may accord, not only for the facts and philosophy involved in the narrative, but also for the services of our intrepid conscientious and faithful instrument, who, during nearly two years, devoted her time, her energy and such ability, as she alone of Earth's sensitives, at this period possesses, for the accomplishment of an object which long has concerned the denizens of our and other spirit worlds, an object for which wittingly she became re-embodied.
