Again according to Mr Dyer, when a spot was haunted by the spirit of a murderer or suicide who lay buried there, a magic circle was made just over the grave, and he who was daring enough to venture there, at midnight, preferably when the elements were at their worst, would conjure the ghost to appear and give its reason for haunting the spot. In answer to the summons there was generally a long, unnatural silence, which was succeeded by a tremendous crash, when the phantasm would appear, and, in ghastly, hollow tones answer all the questions put to it. Never once would it encroach on the circle, and on its interrogator promising to carry out its wishes, it would suddenly vanish and never again walk abroad. If the hauntings were in a house, the investigator entered the haunted room at midnight with a candle, and compass, and a crucifix or Bible. After carefully shutting the door, and describing a circle on the floor, in which he drew a cross, he placed within it a chair, and table, and on the latter, put the crucifix, a Bible, and a lighted candle. He then sat down on the chair and awaited the advent of the apparition, which either entered noiselessly or with a terrific crash. On the promise that its wishes would be fulfilled, the ghost withdrew, and there were no more disturbances. Sometimes the investigator, if he were a priest, would sprinkle the phantasm with holy water and sometimes make passes over it with the crucifix, but the results were always the same; it responded to all the questions that were put to it and never troubled the house again.
How different from what happens in reality! Though I have seen and interrogated many ghosts, I have never had a reply, or anything in the shape of a reply, nor perceived any alteration in their expression that would in any way lead me to suppose they had understood me; and as to exorcism--well, I know of innumerable cases where it has been tried, and tried by the most pious of clergy--clergy of all denominations--and singularly failed. It is true I have never experimented with a magic circle, but, somehow, I have not much faith in it.
In China the method of expelling ghosts from haunted houses has been described as follows:--An altar containing tapers and incense sticks is erected in the spot where the manifestations are most frequent. A Taoist priest is then summoned, and enters the house dressed in a red robe, with blue stockings and a black cap. He has with him a sword, made of the wood of the peach or date tree, the hilt and guard of which are covered with red cloth. Written in ink on the blade of the sword is a charm against ghosts. Advancing to the altar, the priest deposits his sword on it. He then prepares a mystic scroll, which he burns, collecting and emptying the ashes into a cup of spring water. Next, he takes the sword in his right hand and the cup in his left, and, after taking seven paces to the left and eight to the right, he says: "Gods of heaven and earth, invest me with the heavy seal, in order that I may eject from this dwelling-house all kinds of evil spirits. Should any disobey me, give me power to deliver them for safe custody to rulers of such demons." Then, addressing the ghost in a loud voice, he says: "As quick as lightning depart from this house." This done, he takes a bunch of willow, dips it in the cup, and sprinkles it in the east, west, north, and south corners of the house, and, laying it down, picks up his sword and cup, and, going to the east corner of the building, calls out: "I have the authority, Tai-Shaong-Loo-Kivan." He then fills his mouth with water from the cup, and spits it out on the wall, exclaiming: "Kill the green evil spirits which come from unlucky stars, or let them be driven away." This ceremony he repeats at the south, west, and north corners respectively, substituting, in turn, red, white, and yellow in the place of green. The attendants then beat gongs, drums, and tom-toms, and the exorcist cries out: "Evil spirits from the east, I send back to the east; evil spirits from the south, I send back to the south," and so on. Finally, he goes to the door of the house, and, after making some mystical signs in the air, manoeuvres with his sword, congratulates the owner of the establishment on the expulsion of the ghosts, and demands his fee.
