On one occasion, when I knew he was about to use the prepared slate (Professor Thompson will remember what I am about to relate), I suggested that we should use a perfectly fresh pencil, so that we could be sure that that very pencil had done the writing. I was very curious to know how he would evade the test. The slate was held close to the under side of the table (the new pencil debarred him from using the double slate); when the writing was finished the slate was slapped violently against the table, and was drawn from underneath it--apparently with very great difficulty, and almost perpendicularly--and the little pencil, of course, slipped off, and in the excitement of reading the message from the 'Summer-land,' who would think of looking for the pencil? It was so clever I wanted to applaud him on the spot.
The other tricks, such as tossing the pencil from the slate and playing the accordion, can be perfectly explained and repeated by Mr. Sellers. Dr. Slade's fingers are unusually long and strong, and the accordion, which has but four bellows-folds, can be readily manipulated with one hand.
At our last séance I noticed what were evidently two prepared slates resting against the support of the table behind him, where his prepared slates usually stood. I inferred that he would like to have some extraordinary slate writing on this occasion, and, therefore, kept a sharp watch on these slates. Unfortunately it was too sharp, for one second the Medium saw me looking at them. It was enough. That detected look prevented the revelation of those elaborate Spirit messages. But when the séance was over and he was signing the receipt for his money, I passed round behind his chair and pushed these slates with my foot so as to make them fall over, whereupon the writing on one of them was distinctly revealed.
I think Dr. Pepper and Mr. Sellers will recall how the Medium instantly pushed his chair back until it was fairly over the slates and then snatched them up, and in the most hurried manner washed them both while turning his back to us.
Two compasses, which we placed on the table during our séance, remained unaffected by the Medium's presence.
During one sitting, when the Spirits conveyed the slates from the Medium's hand under the table to the hand of the opposite sitter, the latter failed twice to grasp the slate in time, and it fell to the floor with a crash. Each time it behoved me to pick up the slate (both the other sitters were women), but the second time I stooped with the greatest alacrity and looked not at the slate but at the Medium's foot, which I saw just entering his slipper, into which it most hastily settled.
