Then the medium pulled a cord which was attached to a light enclosed in a sheet-iron case, the one small opening of which was covered with several thicknesses of green tissue paper. When she pulled the string the room became darker than ever. SPIRITS BEGIN TO MOVE. Before she began her incantations the medium had requested everyone present not to cross their feet, and to try to assist her to bring the spirits before them. She said that it would probably not be possible to bring a spirit for everybody, but that if all helped her, the spirits wanted by many in the audience would surely appear. Then she asked them all to sing "Nearer, My God, to Thee," which they did, and after a few more passes over her temples and in front of her eyes the spirit began to move. The detectives could see it, and they began to think they had been wrong in thinking there was nothing in spiritualism. It certainly appeared real. First one form would glide back and forth in front of the curtain, then an entirely different one would appear. Altogether there were spirits of about ten men and children materialized. As the apparitions moved slowly in front of the curtain, in the spectral light which made it impossible to detect more than a faint outline of the form, women rushed forward crying out that it was their husband, or their child, that they saw. They stretched out their hands to clasp the forms of their departed, but Jennie Nichols and her male assistant would take them by their hands and tell them they must not touch the spirit or it would fade away. You could get within six inches of the figures, and peer into the faces as they passed to and fro, but everyone was restrained from attempting to touch them. In the ghostly light of the room the closest inspection could not determine that the figures were frauds, so clever were they disguised. KEYS UP THE SPECTATORS. While the detectives were waiting for the materialization, a woman they knew entered the room. Barry put his handkerchief up to his face for fear she would recognize him. They wanted to know what was the matter with him, and Barry said that he guessed he had something in his eye. They wanted to take it out, and he had to put his handkerchief away. He thought he was discovered, but the woman, Mrs. Ella Hoobler, 319 West Madison street, said nothing about him. After they had arrested the Nichols woman, Mrs. Hoobler told Barry she had recognized him when she first entered the room, but she thought he was "bug" in the game, and said nothing. After about ten materializations of husbands and children had keyed the spectators up to a high pitch, Mrs. Hoobler asked for the spirit of her daughter, Helen. In a few minutes the figure of a young girl, clad in white from head to foot, appeared before the curtain. "Oh, Helen, my Helen!" Mrs. Hoobler exclaimed, rushing to the apparition. "Oh, mamma!" came the answer in a shrill falsetto voice. [Illustration: Medium's Paraphernalia Seized by Police in Raid.]
