Regarding the possibility of using codes and cues before others without being detected I can say positively that it is not only possible but simple and practical. I had a fox terrier by the name of “Bobby” that I trained to pick up cards by a cue. On May 31, 1918, I performed with this dog before the Society of American Magicians and I do not believe that there was one in the audience who detected my silent cue. I spoke about this to a number of expert professionals who thought, to all intents and purposes, that Bobby was listening to my speech, whereas I was silently cueing him all the time. I do not wish to expose the silent cue as I know that the great dog trainers of the world use it and it would not be fair to them to make it public. I was able to give Bobby his silent cue in any room or even a newspaper office and the spectators could watch me closely all the time because I never made a move they could see or a sound they could hear. It is common to train other animals in a similar way. During one of my tours in Germany I saw a horse called “Kluge Hans” that was able to spell, add, subtract, pick out cards, and with his feet make one tap for yes and two taps for no. Kluge Hans fooled the professors for a long time but finally it came out that he got his cues from the trainer’s assistant. It is not generally known that, owing to the position of his eyes, a horse can look backwards to a certain degree and the investigators did not notice the assistant who stood just back of the horse’s head. At one time William Eglinton, an English medium, was undoubtedly considered by Spiritualists the most powerful professional psychic not only in England but throughout a greater part of Europe. In 1876 he held the palm as a successor to Slade in slate writing tricks. He was a strong card for the cause and was extolled and lauded to the skies by the Spiritualistic press. He produced varied phenomena in addition to his slate writing effects, such as the movement of articles, production of Spirit lights, and materialization. The Spiritualists have told that “he was so skillful that several practised conjurors as well as many investigators” were at a loss to detect or account for his methods. That may have been so. Half a century ago conjurors were not up on Spiritualism as they are to-day, and besides, it must be conceded that even conjurors are not immune to being deceived. Nevertheless there were conjurors and lay investigators fully qualified to discover and expose his frauds.
