Often a landlord's enemies spread rumors that the house is haunted, so that he may not be able to get a tenant. Sometimes pretended spiritualists, who have made this their life's occupation, make it as interesting a play as they can, by arranging some knocks from here and there, by lifting the chairs and tables with an arrangement of wires, by producing effects of light and shade with phosphorus; they take advantage of the simple-minded. Some pretend to carry messages from the spirit world or to it, and deceive many earnest enquirers into these matters. Many carry out their questionable purposes by holding spirit meetings. All this drives material people, unbelievers in the spirit, still further away from the knowledge of the finer existence, while the so-called spiritualists are often so much engrossed in their hobby that they never realize their own spirit.
