By the time the end doors are closed and bolted, the Davenports, in many instances, have succeeded in loosening the knots next their wrists, and in slipping their hands out, the latter being then exhibited at the aperture. Lest the hands should be recognized as belonging to the mediums, they are kept in a constant shaking motion while in view; and to make the hands look large or small, they spread or press together the fingers. With that peculiar rapid motion imparted to them, four hands in the aperture will appear to be half-a-dozen. A lady's flesh colored kid glove, nicely stuffed with cotton, is sometimes exhibited as a female hand--a critical observation of it never being allowed. It does not take the medium long to draw the knots close to their wrists again. They are then ready to be inspected by the Committee, who report them tied as they were left. Supposing them to have been securely bound all the while, those who witness the show are very naturally astonished. Sometimes, after being tied by a committee, the mediums cannot readily extricate their hands and get them back as they were; in which case they release themselves entirely from the ropes before the doors are again opened, concluding to wait till after "the spirits" have bound them, before showing hands or making music. It is a common thing for these impostors to give the rope between their hands a twist while those limbs are being bound; and that movement, if dexterously made, while the attention of the committee-men is momentarily diverted, is not likely to be detected. Reversing that movement will let the hand out. The great point with the Davenports in tying themselves is, to have a knot next their wrists that looks solid, "fair and square," at the same time that they can slip it and get their hands out in a moment. There are several ways of forming such a knot, one of which I will attempt to describe. In the middle of a rope a square knot is tied, loosely at first, so that the ends of the rope can be tucked through, in opposite directions, below the knot, and the latter is then drawn tight. There are then two loops--which should be made small--through which the hands are to pass after the rest of the tying is done. Just sufficient slack is left to admit of the hands passing through the loops, which, lastly, are drawn close to the wrists, the knot coming between the latter. No one, from the appearance of such a knot, would suspect it could be slipped. The mediums thus tied can, immediately after the committee have inspected the knots, and closed the doors, show hands or play upon musical instruments, and in a few seconds be, to all appearance, firmly tied again.
