"The circle was made up about equally of men and women, all of them well-known residents of the town. So far as most of the phenomena resulting from this sitting are concerned, they have very little value, for they took place in the dark and the medium was not closely guarded. It was only toward the end of the sitting, which, by-the-way, took place in Miss Halsey's library and music-room, that the unexpected suddenly happened, the inexplicable came to pass. "We were gathered about a long table, with Mrs. Smiley at one end sandwiched between the editor of the local paper and myself. Behind me, and just within reach of my hand, stood an upright piano, with its cover down, but not locked. We had heard drumming on the table for some time, and writing had apparently taken place on the pads in the middle of the table. But all this was inconclusive, for the reason that Mrs. Smiley was not fastened as she is now. I took it all with a pinch of salt. My mental reservations must have reached the minds of the 'guides,' for with startling suddenness they left the table and fell upon the top of the piano. After drumming for some time, the invisible fingers seemed to drop to the strings beneath, and a treble note was sounded as if plucked by a strong hand." "You are sure the piano was closed?" "I am coming to that. Highly delighted by this immediate response to my request, I said to the 'forces': 'Can't you demonstrate to us that these sounds are not accidental or caused by the jarring of cars in the street? Can't you pluck the bass strings?' Instantly, and with clangor, the lower strings replied. Thereupon I said: 'Can't you play a tune?' To this only a confused jangle made answer. I was unable to secure any orderly succession of notes. 'Can't you keep time while I whistle?' I insisted, with intent to show that intelligence guided these sounds. The 'spirits' twanged three times in the affirmative, and when I began to whistle 'Yankee Doodle' the invisible musician kept perfect time, playing according to my request--now on the treble, now on the bass. Leaning far back in my chair, I placed my hand upon the lid of the closed piano, and called out to the others in the circle: 'The lid of the piano is closed. My hand is upon it. So far as the sense of touch and hearing are concerned, we have here an action absolutely unaccounted for by any scientific law. "This was at the moment absolutely convincing to me, as to the others, and I promptly reported the case to the American Psychical Society in Boston. Since then I may say I have had many experiments quite as convincing, but never a repetition of this peculiar phenomenon. It is useless to talk about secret wires, or a mouse running up and down the strings, or any other material explanation of this fact. It took place precisely as I relate it, and remains a mystery to this day." Fowler remained very calm. "Crookes saw in a full light an accordion playing beneath the touch of invisible fingers."
