The peculiar manner of holding the hands, described above, enables the medium to secure for her use, a ligature of knotted cloth between her hands, some six inches long; and the central bandage, usually tied in four or five double knots, gives her about two inches play between the middle of the cotton handcuffs and the ring in the post, to which it is secured. The ring is two and a half inches in diameter, and the staple which holds it to the stanchion is a half inch. The left hand of the medium gives six additional inches, and the bandage on her wrist slips readily along her slender arm nearly half way to the elbow--"all of which," says John W. Truesdell,[3] who was the first to expose Miss Fay's spirit pretensions, "gives the spirits a clear leeway of not less than 20 inches from the stanchion. The moment the curtain is closed, the medium, under spirit influence spreads her hands as far apart as possible, an act which stretches the knotted ligature so that the bandage about it will easily slip from the centre to either wrist; then, throwing her lithe form by a quick movement, to the left, so that her hips will pass the stanchion without moving her feet from the floor, the spirits are able, through the medium, to reach whatever may have been placed upon her lap." One of Annie Eva's most convincing tests is the accordion which plays, after it has been bound fast with tapes and the tapes carefully sealed at every note, so as to prevent its being performed on in the regular manner. Her method of operating, though simple, is decidedly ingenious. She places a small tube in the valve-hole of the instrument, breathes and blows alternately into it, and then by fingering the keys, executes an air with excellent effect. Sometimes she places a musical box on an oblong plate of glass suspended from the ceiling by four cords. The box plays and stops at word of command, much to the astonishment of listeners. "Electricity," exclaims the reader! Hardly so, for the box is completely insulated on the sheet of glass. Then how is it done? Mr. Asprey Vere, an investigator of spirit phenomena, tells the secret in the following words: ("Modern Magic"). "In the box there is placed a balance lever which when the glass is in the slightest degree tilted, arrests the fly-fan, and thus prevents the machinery from moving. At the word of command the glass is made level, and the fly-fan being released, the machinery moves, and a tune is played. When commanded to stop, either side of the cord is pulled by a confederate behind the scenes, the balance lever drops, the fly-fan is arrested, and the music stops." One of the tests presented to the American public by this medium is the "spirit-hand," constructed of painted wood or _papier mache_, which raps out answers to questions, after it has been isolated from all contact by being placed on a sheet of glass supported on the backs of two chairs.
