The handcuff trick is always a great favorite with the medium. He has no objection to placing his hands in any pair of handcuffs furnished by the audience. A few moments after he has entered the cabinet, he begins throwing out various articles of clothing; but, on examination, the handcuffs are found to be still on his wrists. It is impossible to see how he could have taken off his coat. As a final test the medium comes out of the cabinet holding the handcuffs in his hand still locked. There are only a few styles of handcuffs made, and all the medium has to do is to secure the proper key for each style. He conceals these keys on his person, and by the aid of his fingers and teeth the proper key can be fitted to the handcuffs. It is impossible, with some types of handcuffs, to get the fingers to the keyhole. If such a pair are placed on the performer, and he cannot use his teeth to hold the key, he slips the key into a convenient crack in the cabinet or in the chair. The lock of the handcuffs being forced on to the key, the handcuffs can then be readily unlocked. The spirit collar is also a favorite instrument of the medium. It consists of a brass collar which fits closely about the performer’s neck. Through the openings in the end of the collar, is placed a chain. After the collar is on the performer’s neck, the chain is placed around a post and carried back and through the padlock used to lock the collar. By this arrangement the performer is securely fastened to a post; but after he is concealed by the use of any convenient means, he suddenly appears before the audience minus the collar, while the collar will be found locked, as before. The trick depends for its success on the series of bolts with which the collar is studded. The bolts, with one exception, are all false, being pieces of metal simply screwed into the top and bottom of the collar, and not penetrating through them. One bolt, however, passes through the collar and engages the two parts thereof; the parts terminate in a tongue which fits in the socket in the other half of the collar. The bolt passes through this tongue so accurately that there is no danger of its being removed with the fingers. The performer uses a small wrench to remove the bolt.
