This theory apparently has both merits and difficulties, which at present we can only briefly notice. Among the strong points in its favor, the first and most conspicuous one is, that it accords with what this mysterious intelligence, in all its numerous forms of manifestation, has steadily, against all opposition, persisted in claiming _for itself_, from its first appearance, over twenty years ago, till this day. And singularly enough, it appears as a fact which, perhaps, should be stated as a portion of the history of these phenomena, that years before public attention and investigation were challenged by the first physical manifestation that claimed a spiritual origin, an approaching and general revisitation of departed human spirits was, in several instances, the burden of _remarkable predictions_. I have in my possession a little book, or bound pamphlet, entitled, "A Return of Departed Spirits," and bearing the imprint, "Philadelphia: Published by J. R. Colon, 203½ Chestnut Street, 1843," in which is contained an account of strange phenomena which occurred among the Shakers at New Lebanon, N. Y., during the early part of that year. In the language of the author: "Disembodied spirits began to take possession of the bodies of the brethren and sisters; and thus, by using them as instruments, made themselves known by speaking through the individuals whom they had got into." The writer then goes on to describe what purported to be the visitations of hundreds in that way, from different nations and tribes that had lived on earth in different ages--the consistency of the phenomena being maintained throughout. I have conversed with leading men among the Shakers of the United States concerning this affair, and they tell me that the visitation was not confined to New Lebanon, but extended, more or less, to all the Shaker communities in the United States--not spreading from one to another, but appearing nearly simultaneously in all. They also tell me that the phenomena ceased about as suddenly as they appeared; and that when the brethren were assembled, by previous appointment, to take leave of their spirit-guests, they were exhorted by the latter to treasure up these things in their hearts; to say nothing about them to the world's people, but to wait patiently, and soon they (the spirits) would return, and make their presence known to the world generally. During the interval between the autumn of 1845 and the spring of 1847, a book, wonderful for its inculcations both of truth and error, was dictated in the mesmeric state by an uneducated boy--A. J. Davis--in which the following similar prediction occurs:
