" May 5. There being, at this stage of development on Mars, no winter with its concomitants of winds and storm, snow and ice, you have no difficulty in apprehending that very light material only is needed to protect and render comfortable the persons of the people. Material of the texture of your lightest flannel underwear would be oppressively and uncomfort-ably warm, and indeed insufferable. Thin and quite gauzy robes composed of finely attenuated and exquisitely refined material constitute their apparel. I have told you hitherto that of the animal kingdom only the fittest have survived the marvelous successive changes in the infinite series of progressive advancements. Among those now living with the ability of propagation is an animal species somewhat resembling-your sheep, but so exceedingly refined as to be remarkably striking in contrast. Of course, and in the very nature of things, the fleecy wool, or, rather velvety down, that grows upon this noble animal, so distinguished for innocence, aesthetic tastes in food and refinement in habits of life, is eminently suited for purposes of habilament, and accordingly is thus utilized. They are propagated in unlimited numbers, live to an advanced age, are the common property of all the people, and have within themselves the qualities of eternal being.
" The forest and other trees, shrubs and flowers, have advanced under the same law of progress. Very many species of the olden time disappearing—the fittest only having survived. Among those now extant on the planet, is a peculiar and quite extensively cultivated species, from which is produced a fabric resembling somewhat your cotton production, with the same difference in refinement of texture as exists between your wool and that developed on Mars as herein stated. This is utilized for raiment also. Besides the people there have mastered the law that spirits employ in the materialization of garments at your materializing seances, only much finer, and of the ambiant atmosphere, filled as it is with sublimated atoms and emanations, they are enabled to collect and magnetize into solidified form appropriate garments for their use and comfort. When thus magnetized into objective and tangible being it partakes of and assumes a varied hue and color, according to the progressed and advanced state of the person using the garments. In other words the magnetic aura and spiritual emanations proceeding from the individual infiltrates and becomes interwoven in the delicate fibers of the new garment extracted and brought into being from the viewless air, imparting hue and coloration presenting different appearances, whereby the grade or degree of advancement of the individual wearer is made known and determined. Here you inquire of the spirits to know what sphere you are fitted to enter in the spirit world, then they know by this means in advance of leaving the body. Your spirits in imparting light and knowledge to you concerning their state, tell you that a spirit and its proper sphere are known by the peculiar aura, or surroundings and clothing of the individual spirit, and this is true to the letter. But on Mars this law of spirit designation that belongs to the spiritual spheres of your planet, reaches out and reveals itself in the persons of the people of Mars before they have actually entered upon the spiritual journey of life in the spiritual spheres.
" Now the additional fact is disclosed to you that by reason of this mode of obtaining raiment the avocation of the merchant is of slender dimensions, and the manufacturer's art and pursuit, except as known and practiced by all alike, are now unknown on the planet Mars.
" In our next we will discourse on buildings, habitations, etc We had hoped to reach this part of the subject in this communication, but as we advance the themes and subjects broaden and expand, and we sincerely regret that the power by this process—independent slate writing—although the purest of all, will not last us at one sitting sufficiently to fully elaborate our thoughts and descriptive delineations on a given subject. It has this advantage, however, it comes directly from the materialized fingers of the spirit without the direct use of the brain of another in transmission. Adieu until our next.
" May 8. The same reasons assigned in our last, why very light garments only were needed for the bodily comfort and happiness of the people of Mars apply with equal propriety, force, and truth, to the subject of their habitations.
" Your rains are produced by vapors, mists, and emanations from your oceans, rivers, lakes, etc, which by virtue of solar attraction or a reversal of the law of gravitation the vapors, mists, etc., are drawn upward in space until a certain density is reached, differing in altitudes of height, when they become congealed by the force of the cold attenuated atmosphere there into small particles called rain drops, and these are carried along by the undercurrents of un-congealed clouds until a certain electro-magnetic condition is reached, when the clouds begin to empty and rid themselves of their burdened contents.
" Now we have informed you of the progress the water of Mars has made in being dispossessed of its gross and mighty elements; hence there are none of these to ascend and to commingle in the formation of rain drops; hence none but the purer and refined elements of the water are exhaled and drawn upward, and consequently none but the pure and refined descend. These are in themselves comparatively light and of greatly diminished gravity, and therefore mild and pleasant in their effect. Especially does this become true as a resulting necessity, from the fact that there are no fierce winds or storms or cold temperature in the surrounding atmospheric belts or zones. The rains on Mars are more like your gentle dews of early autumn than your rains and showers. You at once take in the situation from this and preceding statements of facts that crude material structures are not necessary, even if the material for their construction could be found, and we have seen that such is not the case, for all things, including the material in detail out of which edifices are constructed, have progressed beyond and above their crude grossness.
