It was explained to Miss Miller that the wonderful cures which the medium professed to be able to make were brought about while the patient was in a trance. In a letter which had been turned over to the police, "Professor Venazo," which is the name with which an accomplice of certain Chicago mediums signed such communications, explained that because of stress of business it would be impossible to undertake to cure Miss Miller of her deafness unless she was prepared to put up at least $50 in cash. The letter stated that if she would send to "Professor Venazo" $100 the medium would undertake to go to her home and cure her there. If she did not wish to pay that much money she could come to Chicago, pay the medium $50, and be cured "while in a trance." Detectives Barry and David Carroll were detailed to assist Wooldridge in serving the warrants and making the raid. DETECTIVES ATTEND SERVICE. Barry and Carroll planned to effect an entrance to the "seance." Inspector Revere was informed and asked to give a detail of six officers, who, headed by Detective Wooldridge, went to the hall on Sebor street. Barry and Carroll had preceded them and succeeded in convincing Jennie Nichols, who was the master of ceremonies, that they were interested in spiritualism and desired to witness the materializations. When they went to the hall, Detective Barry walked in and found twenty-eight or thirty others there before him. Jennie Nichols was busy arranging the spectators in seats. She took a great deal of care about placing them. Carroll and Barry entered and signed their names on the register. This was a book in which everyone who is admitted to a seance is requested to place his name and place of residence. Barry signed as "John Woods"; address, 142 Ashland boulevard. CALLING UP THE SPIRITS. When the seance opened Jennie Nichols conducted those who were in the hall through the main room and the one at the rear, before which the curtain was placed. Everything was all right, so far as Detectives Barry and Carroll could see. The cabinet from which the spirits were to come stood across one corner, and opposite it was a door leading into one of the two rooms in the rear of the hall. They examined the cabinet and the rooms carefully, but found everything all right. After they had been through everything the doors were locked and they returned to their seats, Miss Nichols making some other changes in the arrangements of the seats, and then the place was darkened. When the place had been made almost entirely dark, Jennie Nichols, the medium, began pacing back and forth in front of the curtain. She rubbed her hands over her head and eyes a number of times, and began to chant: "Come, O queen, O queen." When she began to call on the "queen" the spectators began to get excited. Most of them appeared to be thoroughly familiar with the proceedings, and several of them said: "Oh, I hope it's the king."
