As for America being overflowed with sensitives and mediums, the reason for it is partially attributable to climatic influence and especially to the physiological condition of the population. Since the days of the Salem witchcraft, 200 years ago, when the comparatively few settlers had pure and unadulterated blood in their veins, nothing much had been heard of “spirits” or “mediums” until 1840.[26] The phenomena then first appeared among the ascetic and exalted Shakers, whose religious aspirations, peculiar mode of life, moral purity, and physical chastity all led to the production of independent phenomena of a psychological as well as physical nature. Hundreds of thousands, and even millions of men from various climates and of different constitutions and habits, have, since 1692, invaded North America, and by intermarrying have substantially changed the physical type of the inhabitants. Of what country in the world do the women’s constitutions bear comparison with the delicate, nervous, and sensitive constitutions of the feminine portion of the population of the United States? We were struck on our arrival in the country with the semi-transparent delicacy of skin of the natives of both sexes. Compare a hard-working Irish factory girl or boy, with one from a genuine American family. Look at their hands. One works as hard as the other; they are of equal age, and both seemingly healthy; and still, while the hands of the one, after an hour’s soaping, will show a skin little softer than that of a young alligator, those of the other, notwithstanding constant use, will allow you to observe the circulation of the blood under the thin and delicate epidermis. No wonder, then, that while America is the conservatory of sensitives the majority of its clergy, unable to produce divine or any other miracles, stoutly deny the possibility of any phenomena except those produced by tricks and juggling. And no wonder also that the Catholic priesthood, who are practically aware of the existence of magic and spiritual phenomena, and believe in them while dreading their consequences, try to attribute the whole to the agency of the Devil.
