Modern Magic: A Practical Treatise on the Art of Conjuring
Professor Hoffmann279If a pin be thrust into this hole, the purpose of the two is immediately manifest; for the pressure of the pin releases a tiny catch, and allows the bottom of the drawer, which is in reality only supported by this catch at the back and a cloth hinge in the front, to drop into the position indicated in Fig. 90. This is precisely what takes place when the drawer, being restored to its proper position in the cabinet, is duly closed. The pressure of the brass pin at the back releases the catch, and the bottom of the drawer falls as just described, and allows any article which may have been placed therein to drop into the hand of the person holding the cabinet. (See Fig. 91.) The act of pulling out the drawer again presses the bottom up to its proper place, where it is secured by the catch until once more released by the pressure of the pin. The strong point of this ingenious little apparatus is that it is absolutely self-acting, and its secret can only be detected by examining the cabinet from below at the moment when the drawer is pushed home; and this it is easy to prevent by the simple expedient of handing each portion separately for inspection. The performer begins by handing first the cabinet and then the drawer for examination. Then, placing the cabinet on the palm of his hand, he invites any one of the audience to deposit any small article, a coin, a ring, a watch, etc., in the drawer, and to replace the drawer in the cabinet. As soon as the drawer is closed, the article drops through into his hand. Taking hold of the cabinet with the other hand (lifting it by the top only, and with the very tips of his fingers, so as to preclude all apparent possibility of deception), he places it on the table or elsewhere, in full view. Having thus gained possession of the borrowed article, he concludes the trick by reproducing it in any manner he thinks proper.
