From this period until the time of the War I continued in the leisure hours of a very busy life to devote attention to this subject. I had experience of one series of seances with very amazing results, including several materializations seen in dim light. As the medium was detected in trickery shortly afterwards I wiped these off entirely as evidence. At the same time I think that the presumption is very clear, that in the case of some mediums like Eusapia Palladino they may be guilty of trickery when their powers fail them, and yet at other times have very genuine gifts. Mediumship in its lowest forms is a purely physical gift with no relation to morality and in many cases it is intermittent and cannot be controlled at will. Eusapia was at least twice convicted of very clumsy and foolish fraud, whereas she several times sustained long examinations under every possible test condition at the hands of scientific committees which contained some of the best names of France, Italy, and England. However, I personally prefer to cut my experience with a discredited medium out of my record, and I think that all physical phenomena produced in the dark must necessarily lose much of their value, unless they are accompanied by evidential messages as well. It is the custom of our critics to assume that if you cut out the mediums who got into trouble you would have to cut out nearly all your evidence. That is not so at all. Up to the time of this incident I had never sat with a professional medium at all, and yet I had certainly accumulated some evidence. The greatest medium of all, Mr. D. D. Home, showed his phenomena in broad daylight, and was ready to submit to every test and no charge of trickery was ever substantiated against him. So it was with many others. It is only fair to state in addition that when a public medium is a fair mark for notoriety hunters, for amateur detectives and for sensational reporters, and when he is dealing with obscure elusive phenomena and has to defend himself before juries and judges who, as a rule, know nothing about the conditions which influence the phenomena, it would be wonderful if a man could get through without an occasional scandal. At the same time the whole system of paying by results, which is practically the present system, since if a medium never gets results he would soon get no payments, is a vicious one. It is only when the professional medium can be guaranteed an annuity which will be independent of results, that we can eliminate the strong temptation, to substitute pretended phenomena when the real ones are wanting.
