“The secret of the trick is as follows: That part of the wood which forms the chin is replaced by a small strip of iron, which is painted the same color as the mask, so that it cannot be seen; an electro-magnet is let into the top of the table, so that the cores shall be opposite the strip of iron when the mask is laid upon the table. Contact is made by means of a push-button somewhere in the side scenes; the wires run under the stage, and connection is made through the legs of the table when the legs are set on the foreordained place.”—Hopkins’ Magic, etc.
