The Spiritualist reader here impatiently observes that I am merely picking out a few little irregularities in the early days of the movement. Far from it. I am scientifically studying the preparatory stages of one of the classic manifestations of the movement: the materializations of Florence Cook, which are vouched for by Sir W. Crookes, Sir A. C. Doyle, and, apparently, all the leaders of the movement. If the Spiritualist wishes, like other people, honestly to understand "Katie King," he or she must read this part of the story which I am giving, and which is generally omitted (though it may be read in any history of the movement). Florence Cook was a pretty little Hackney girl of sixteen when Herne and Williams began. She attended séances at their house in Lamb's Conduit Street, and she was so impressed that she became a pupil of Herne. She and her father seem to have understood each other very well, and she very shortly began to give, to paying guests, materialization-séances in their house at Hackney. Florence went one better than Mrs. Guppy and Herne. There was a lamp in the room--at the far side of the room--and you saw faces plainly at the opening in the cabinet. As her "power" developed, the ghost began to leave the cabinet and walk about the room and talk to the sitters. Florence remained bound with rope in the cabinet while "Katie King" stalked abroad. You did not see her, it is true, but you had her word for it. She was not bound by the spectators--nor by herself, of course. She was bound by the spirits. A rope was put on her lap, the curtains were drawn, and presently you discovered Florrie, "securely" bound and in a trance, in the cabinet. The curtains were drawn again when the ghost, in flowing white drapery, walked the room. Meantime, and at a very early date, a Manchester Spiritualist named Blackburn privately engaged to give Florrie an annual fee if she would not take money at the door; so she became an "unpaid" and highly respectable medium. Jewellery is, of course, not money, and Florrie exacted jewellery (as the Spiritualist Volckmann found and said in the London Press at the time, when he wanted to attend) from would-be sitters through her father. It is said that she looked, in features, remarkably like a Jewess.
