No sensible man will pay serious attention to spirit photographs until one is taken in these conditions; neither plates nor any single part of the apparatus shall belong to or be touched by the medium. The spirit photographer shall be brought to an unknown studio, and shall not be allowed to do more than, under the eye of an expert observer, lay his hand, at a sufficient distance from the lens, on the outside of a camera which does not belong to him. That has not been done yet. Until it is done fraud is certainly not excluded; and any man who uses the medium's own premises and apparatus is courting deception. That the ghost on a photograph often resembles a dead relative of the sitter will surprise no sensible person. It is well known that mediums collect such photographs, as well as information about the dead. Mr. Carrington describes in his _Physical Phenomena of Spiritualism_ the elaborate system they have. They have considerable knowledge of likely sitters in their own town. In fact, I have clearly enough traced in some cases that they _first_ gathered information about a man, and _then_ got an intermediary to persuade him to visit them. He, of course, tells everybody afterwards that the medium "could not possibly" know anything about him. Sometimes a Spiritualist takes the precaution of going to a spirit photographer in a distant town. If he is quite able to conceal his identity, he will get nothing, or only a common or garden ghost. But he makes an appointment for a sitting in a few days to try again, and gives his name and address; and the next mail takes a letter to a medium in his town asking for information and photographs. As I have previously said, when the Berlin police arrested Frau Abend and her husband they found an encyclopædic mass of information about possible sitters. A case, with which I may conclude this section, is given by Dr. Tuckett in his _Evidence for the Supernatural_ (pp. 52-3). Mr. Stead was once delighted to find the ghost of a "brother Boer" on a photograph, and the clairvoyant photographer mystically informed him that he "got" the name "Piet Botha," and gathered that he had been shot in the Boer War. Mr. Stead was jubilant, and the Materialist was nowhere, when he learned that Piet Botha _had_ been shot in the war. Who in England knew anything about Piet Botha and his death? But the wicked sceptic got to work, and he presently discovered that on November 9, 1899, the _Graphic_ had reproduced a photograph of Piet Botha, who had been shot in the war! A magnificent case fell completely to pieces.
