The evidence of Dr. G. H. La Fetra, of Washington, D. C., is sufficiently convincing on this point. Said Dr. La Fetra to me: "Some years ago I went with a friend, Col. Edward Hayes, to one of Mr. Keeler's light séances. It was rather early in the evening, and but few persons had assembled. Upon the mantel piece of the séance-room were several tablets of paper. Unobserved, I took up these tablets, one at a time, and drew the blade of my pen-knife across one end of each of them, so that I might identify the slips of paper torn therefrom by the nicks in them. In a little while, the room was filled with people, and the séance began; the gas being lowered to a dim religious light. When the time came for the writing, Mr. Keeler requested that some of the tablets of paper on the mantel be passed into the cabinet. This was done. Various persons present received 'spirit' communications, the slips of paper being thrown over the curtain of the cabinet by a 'materialized' hand. Some gentleman picked up the papers and read them, for the benefit of the spectators; afterwards he laid aside those not claimed by anybody. Some of these 'spirit' communications covered almost an entire slip. These were carefully written, some of them in a fine hand. The short messages were roughly scrawled. After the séance, Col. Hayes and myself quietly pocketed a dozen or more of the slips. The next morning at my office we carefully examined them. In every instance, we found that the well-written, lengthy messages were inscribed on _unnicked_ slips, the short ones being written on _nicked_ slips." To me, this evidence of Dr. La Fetra seems most conclusive, proving beyond the shadow of a doubt that Keeler prepared his long communications before the séance and had them concealed upon his person, throwing them out of the cabinet at the proper moment. He used the _nicked_ tablets for his short messages, written on the spot, thereby completely revealing his method of operating to the ingenious investigator.
