The binding of mediums with cords or tapes is a "precaution against fraud" which was thoroughly exposed fifty years ago. Many of Sir A. C. Doyle's own admirers were pained when he announced to the world his belief in the genuineness of the performance of two Welsh colliers, the Thomas brothers. Their "manifestations" were prehistoric. More than fifty years ago spectators were invited to tie up the mediums, and as long ago as 1883 Mr. Maskelyne was exhibiting the trick. The Davenport brothers, the latest American marvels, had toured England. Most people will remember how they were held up at Liverpool by some one tying the rope in knots with which they were not familiar. The spirits failed entirely to play the tambourine when the tying-up was properly done, and the instrument was put out of reach of the medium's mouth. As usual, it had been said for months that fraud was "absolutely excluded." Later mediums found the solution of this difficulty. The medium kept a sharp knife-blade within reach of his teeth, and, when knots proved too stubborn, he cut the rope and freed himself. He had a spare rope in his clothes and fastened himself--or was bound by a confederate--before the lights went up. People thought that they could prevent this by sealing the knots. It was useless. The medium had chewing gum of the same colour as sealing-wax, and the seals were imitated with this. These desperate shifts are, however, rarely necessary. While he is being tied the medium catches a loop of the rope with his thumb, and this gives him plenty of slack to use. I have seen a medium laced tight into a leather arm-case, and get out behind the curtain in three minutes. He had caught a loop of the lace with his thumb, and the rest was tooth work. It was therefore little wonder that when the Thomas brothers were brought from the valleys of South Wales to London their ancient miracles would not work. A recent convert to Spiritualism, Mr. S. A. Moseley, describes their work on their native heath (or hearth) with the same awe and simplicity as Sir A. C. Doyle had done. Many of us knew the history of Spiritualism, and smiled. They were brought to London by the _Daily Express_ in 1919, and here, where sceptics abounded and the need of convincing evidence was at its most acute, "White Eagle" (the Red Indian spirit who controls Will Thomas) and all his band of merry men were powerless. Will Thomas was properly bound, the tambourine and castanets were put out of reach, and his brother was isolated. All that happened--the throwing of a badge-button and a pair of braces to the audience--is within the range of possibilities of the human mouth.
