He kept this small slate next to him out of my view, and really wrote the message on the small slate which was next to him, and which was concealed from my view by the larger slate. He did not read aloud what he had actually written, but merely pretended to do so, repeating something entirely foreign to the subject instead. What he had written really answered my question fully. When he appeared to erase the message, his movements were but a pretense; and he did not erase it at all. When he replaced the large slate on the stack of slates, he, of course, replaced the small one which was concealed under it, message side down. It must be remembered that the operator, at the beginning of the slate trick, first took up and examined the large slate a time or so for a message; and finding none, seemed disappointed, and finally wrote the automatic message; then on being informed that it did not apply to the case, he seemed dissatisfied and appeared to erase it. After the message was written and the slates replaced, he examined the top slate a time or so, and even lifted off a few small slates looking for writing, but did not turn them over; then seeing nothing, he scattered the slates around on the table, leaving their same sides downward; and handing me the cover, he requested me to cover them and place my hands on them. The trick was now practically done. As the slates had been examined so many times and nothing found on them, even after the automatic writing, the majority of persons would testify that there was positively nothing on the slates when the medium left the table. The majority of persons would never remember that he at one time wrote on the large slate and erased it. The message being on a small slate, and these being spread around, few would have known that this message really appeared on the particular small slate that was originally next the top of the stack. Most people would have certified that they cleaned all of the slates themselves, that the medium never touched any of the small ones, and that he only laid his hands on top of the stack a few times. Some would even forget that the medium handled their writing at all before burning it. I am sure that the nickeled tube that carried the dripping water into the space over the glass bowl, had a second tube within it; through which his assistant from the adjoining room either blew, or sent by some mechanism, the chemicals (probably potassium) that would take fire and burn on striking the water. . . . . . When I perform the slate trick described above, after writing the "automatic" message, apparently erasing it, and replacing the slates, I do not scatter the slates around on the table as this medium did. Instead, I proceed as I will now describe.
