When investigators bring their own marked slates with them, screwed tightly together, and sealed, the medium has to adopt different tactics from those employed in the tests before mentioned. He has to call in the aid of a confederate. The audacity of the sealed-slate test is without parallel in the annals of pretended mediumship. For an insight into the secrets of this phase of psychography, the reading public is indebted to a medium, the anonymous author of a remarkably interesting work, "Revelations of a Spirit Medium."

They invariably say to you when approached on the subject: "I took my own marked slates, carefully screwed together, to the medium, and had lengthy messages written upon them by spirit power.
