and that she knew it must be the spirits, for these manifestations had been with them now for six years." We replied (to keep up our argument), "You know that there are persons who think these sounds are all due to some modification of electricity, and others who think that electricity is the very essence of spirituality,[6] and we wish to see in this case how far it may be concerned in the phenomena." There was no resisting this, and we were allowed to proceed. The result was exactly as we anticipated. While standing upon the cushion _they could not rap at all_. The principal rapper saw her predicament, and took her stand upon the cushion so that her dress was partly over the edge of the cushion, but this we objected to, and requested her to stand upon the centre of the cushion, upon the plea that if her dress touched the floor, it would conduct away the electricity. A perfectly empirical reason, of course; but they were none the wiser for that, and as soon as every thing was arranged to our liking, she invoked the spirit to rap. No rap came. Again and again the spirit was besought, but no response was given. She then asked her sister to come and stand upon the cushion with her, thinking, in her subtlety, that two of them would occupy so much room as to give one, at least, a chance to have her dress over the edge of the cushion. But this we were prepared for; and gathered in the skirts of their dresses upon the cushion, upon the same plea as before. The result was the same as with one. No raps. The fact was, their arts were completely baffled, the spirits had fled, and the experiment not only proved the falsity of the assertion that they could rap standing on cushions, or when suspended in a swing, but afforded the most conclusive evidence of the immediate and wilful agency of these Fox girls in producing these sounds.
