In this hush the megaphone was lifted slightly and dropped, making us all start. It was as if a feeble hand had tried to manipulate it without success. "Let us keep test conditions," I urged. "Please do not make a movement now without warning me of your intentions. Keep the circuit closed." Here I addressed "Wilbur": "Let's see if you can handle the cone under strictly test conditions. Come now, lift it! Lift it!" I repeated the command with intent to concentrate all will-power of both psychic and sitters upon the thing desired, as Maxwell was accustomed to do in his experiments with Meurice. Several times the forces strove to carry out my wishes, but could not. Twice the horn rose from the carpet, only to fall back helplessly. Fowler placed it in position each time, marking each new position, while I took note of the convulsive tremor which swept from time to time over the psychic. It was exactly as if she were a dynamo generating some unknown electrical energy, which, after accumulating for a time in her organism (as in a jar), was discharged along the direction of our will, and yet I could not detect any marked synchronism of movement between these impulses and the movement of the horn. After each fall of the cone she moaned and writhed, _but not till the hush of death came over her did the horn move_. So intense was the silence each time that we could hear the slightest breath, the minutest movement of the tin as it scraped along the rug. "It is useless to talk of a confederate," I remarked; "it is of no value to refer this action to the hands of the psychic. We must look to subtler causes for this phenomenon. Perhaps Maxwell's theory that some magnetic power is liberated by the contraction of the larger muscles will account for it, but in no other way." At last the megaphone soared into the air, passed over our heads, and dropped gently upon the table. It did not fall with a bang; on the contrary, it seemed to descend gently--_as if under perfect control of both hand and eye_. And yet I assert there was nothing to indicate that the psychic shared in these movements. She lay as still as a corpse. Nothing but a minute continuous tremor in the thread told that she was still alive. I was enormously impressed by the silence. The darkness seemed athrill with mystery--not the mystery of the discarnate soul, but the mystery of the X-ray. I felt that we were ourselves involved in a production of each and every one of these movements.
