There were in the city three gentlemen who had, for some time, been known as spiritualists; but they were, at the period of Paine's debut as a medium in New York, very skeptical with regard to "physical manifestations." They had, a short time before, detected the Davenports and other professed mediums in the practice of imposture; and they determined not to accept, as true, Paine's pretence to mediumship, till after a thorough investigation of his "manifestations," they should fail to find a material cause for them. After attending several of his seances, these gentlemen concluded that Paine moved the table by means of a mechanical contrivance fixed under the floor. One of this trio of investigators was a mechanic, and he had conceived a way--and it seemed to him the only way--in which the "manifestation" could be produced under the circumstances that apparently attended it. Paine was a mechanic, and these parties were aware of that fact. They made an appointment with him for a private seance. The evening fixed upon, having arrived, they met with him at his room. The table was raised and raps were made upon it, as had been done on previous occasions. One of the three investigators stepped to the door of the room, locked it, put the key in his pocket, took off his coat, and told Mr. Paine that he was determined to search his (Paine's) person, and that if he did not find about him a small short iron rod, by means of which, through a hole in the floor, a lever underneath was worked in moving the table, he (the speaker) would beg his (Mr. Paine's) pardon, and be forever after a firm believer in the power of disembodied spirits to move ponderable bodies. This impressive little speech had a decided and instant effect upon the "medium." "Gentlemen," said the latter, "I might as well own up. Please to be quietly seated, and I will tell you all about it." And he did tell them all about it; subsequently repeating his confession before quite a number of disgusted and cheaply sold spiritualists at the "New York Spiritual Lyceum." The theory formed by one of the three investigators referred to, as to Paine's method of moving the table, was singularly correct.
