produce his phenomena under test conditions in presence of a hostile and aggressively sceptical investigating committee. It is no fault of the medium that this is the case, and it is no test whatever of the genuineness of his phenomena. But it is presumptive, if not conclusive, evidence that the source of his phenomena resides within himself, and hence is amenable to the universal law which governs the action of all subjective intelligence and power. Neither is it any reflection upon the sincerity of the investigator that he fails to witness the phenomena that have been promised. His ignorance of the law which governs the subject-matter, together with his desire to be frank and honest enough with the medium to put him in possession of a knowledge of his sentiments and prejudices, leads him unwittingly to place an insuperable barrier in the way of success. It unfortunately happens that many professional mediums, despairing of success in producing the genuine phenomena, and more than ordinarily anxious to earn the reward of success, will, under such circumstances, resort to fraud and legerdemain. The temptation to do so is great when he reflects upon how much is at stake, the immediate monetary reward promised being the least consideration. His professional pride, his love of approbation, his hope of future fame and emolument in case he succeeds in convincing a sceptical scientific investigator,--all operate to constitute a temptation too great to be always successfully withstood. Besides, he knows that, under favorable conditions, he can produce the genuine phenomena, that he has produced them again and again, and he quiets his conscience by reflecting that it can do no harm to resort to legerdemain to simulate that which he knows to have a genuine existence.
