Modern Magic: A Practical Treatise on the Art of Conjuring
Professor Hoffmann28Where traps are used, and the cloth has therefore to be cut, the hanging cloth is dispensed with, and the table is covered with cloth glued on the top, with a margin round it, after the fashion of a card-table, and this may be done, if preferred, even where the table is without mechanism. The adoption of this plan allows of the introduction of gold mouldings, or other ornamentation, on the front and sides. In our own opinion, unless there is some special reason to the contrary in the mechanical arrangements of the table, the plain hanging cover is preferable, as being least suggestive of apparatus or preparation. The precise height of the table is best determined by the stature of the performer. The servante, or hidden shelf, should be just so high from the ground as to be level with the knuckles of the performer as his arm hangs by his side; and the top of the table should, as already stated, be about six inches higher than this. It will be found that this height will enable the performer secretly to take up or lay down any article thereon without stooping or bending the arm, either of which movements would suggest to the spectators that his hand was occupied in some manner behind the table. One of the first tasks of the novice should be to acquire the power of readily picking up or laying down any article on the servante, without making any corresponding movement of the body, and especially without looking down at his hands. If the performer is uncertain as to the precise whereabouts of a given article, he must ascertain it by a quick glance as he approaches his table, and not after he has placed himself behind it. From this moment he must not again look down, as if once the audience suspect that he has a secret receptacle behind his table, half the magic of his tricks is thenceforth destroyed.
