If flour has been placed in their hands, it makes no difference as to their getting those members out of or into the ropes; but, to show hands at the aperture, or to make a noise on the musical instruments, it is necessary that they should get the flour out of one hand into the other. The moisture of the hand and squeezing, packs the flour into a lump, which can be laid into the other hand and returned without losing any. The little flour that adheres to the empty hand can be wiped off in the pantaloons pocket. The mediums seldom if ever take flour in their hands while they are in the bonds put upon them by the committee. The principal part of the show is after the tying has been done in their own way. Wm. Fay, who accompanies the Davenports, is thus fixed when the hypothetical spirits take the coat off his back. As I before remarked, there are several ways in which the mediums tie themselves. They always do it, however, in such a manner that, though the tying looks secure, they can immediately get one or both hands out. Let committees insist upon untying the knots of the spirits, whether the mediums are willing or not. A little critical observation will enable them to learn the trick. To make this subject of tying clearer, I will repeat that the Davenports always untie themselves by using their hands; as they are able in ninety-nine cases out of a hundred, however impossible it may seem, to release their hands by loosening the knots next their wrists. Sometimes they do this by twisting the rope between their wrists; sometimes it is by keeping their muscles as tense as possible during the tying, so that when relaxed there shall be some slack. Most "committees" know so little about tying, that anybody, by a little pulling, slipping, and wriggling, could slip his hands out of their knots. A violin, bell, and tambourine, with perhaps a guitar and drum, are the instruments used by the Davenports in the cabinet. The one who plays the violin holds the bell in his hand with the bow. The other chap beats the tambourine on his knee, and has a hand for something else. The "mediums" frequently allow a person to remain with them, providing he will let his hands be tied to their knees, the operators having previously been tied by "the spirits." The party who ventures upon that experiment is apt to be considerably "mussed up," as "the spirits" are not very gentle in their manipulations. To expose all the tricks of these impostors would require more space than I can afford at present. They have exhibited throughout the Northern States and the Canadas; but never succeeded very well pecuniarily until about two years ago, when they employed an agent, who advertised them in such a way as to attract public attention. In September last, they went to England, where they have since created considerable excitement.
