They are the most careful of investigators, and, when the medium's trap is located in the door-jamb, will pound the walls, and insist on the carpet being taken up, when they will get upon their hands and knees and make a most searching examination of the floor. They are the closest and most critical of investigators, but they are very careful to examine everywhere EXCEPT WHERE THE DEFECT IS LOCATED. Because one or two men seem to be making such a critical investigation, do not allow that fact to prevent you making one on your own responsibility. Wait until they have finished and then examine not only where they did, but more particularly where they did NOT. Their examination is only for the purpose of misleading others. Their "tests" are received in a way to cause those about them to think they admit them very unwillingly, or because they were so undeniable that they could do nothing else. A great many will probably deny that confederates are ever employed. They are not, by mediums who are not smooth enough to produce that which appears so wonderful as to make a good business for them. The writer would advise those mediums who give such rank seances to employ a few floor workers (they are easily obtained), and see what a difference it would make in the amount of business they will do. Get good ones, those who know human nature, and know when they have said all that is necessary. Most of them are inclined to say too much, thus causing the ordinary man to suspect that they are confederates.
