Portrait of P. T. Barnum P. T. Barnum The Humbugs of the World — Chapter IX (1866)

To prevent any one getting hold of them while operating, they hit upon the plan of passing a rope through a button-hole of each gentleman’s coat, the ends to be held by a trusty person—assigning, as a reason for that arrangement, that it would then be known no one in the circle could assist in producing the manifestations. The plan did not always work well, however; for a skeptic would sometimes cut the rope, and then pounce upon “the spirit”—that is, if he didn’t happen to miss that individual, on account of the darkness and while trying to avoid a collision with the instruments.

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.
