If we credit the Scriptures with any degree of truth, then witches most certainly had the power of calling up the dead in Biblical days, for at Endor the feat--rare even in those times--was accomplished of invoking in material form the phantasms of the good as well as the evil. Though I am of the opinion that no amount of invocation will bring back a phantasm from the higher spiritual planes to-day, unless that invocation be made in very exceptional circumstances, with a specific purpose, I am quite sure that _bona fide_ spirits of the earth-bound do occasionally materialise in answer to the summons of the spiritualist. I do not base this statement on any experience I have ever had, for it is a rather singular fact that, although I have seen many spontaneous phenomena in haunted houses, I have never seen anything resembling, in the slightest degree, a genuine spirit form, at a séance. Therefore, I repeat, I do not base my statement, as to the occasional materialisation of _bona fide_ earth-bound spirits, on any of my experiences, but on those of "sitters" with whom I am intimately acquainted. What benefit can be derived from getting into close touch with earth-bound spirits, _i.e._ with vice and impersonating elementals and the phantasms of dead idiots, lunatics, murderers, suicides, rakes, drunkards, immoral women and silly people of all sorts, is, I think, difficult to say; for my own part, I am only too content to steer clear of them, and confine my attentions to trying to be of service to those apparitions that are, obviously, for some reason, made to appear by the higher occult powers. Thus, what is popularly known as spiritualism is, from my point of view, a mischievous and often very dangerous form of witchcraft.
