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.
