EFFECT. Any pack of cards is shuffled by a spectator and handed to the performer, who lays it face down on the table and asks a person to cut the pack at about the center; to look at and remember the card on the top of the lower part, replace the card and put the portion cut off on top. The spectator squares the cards carefully, cuts it several times and hands it to the performer, who then deals the cards face up, instructing the spectator to merely think 'Stop' when his card makes its appearance. He stops at a certain card which is acknowledged to be the correct card.
WORKING. All that you require is a tiny pellet of wax, about the size of a pin-head in such a position that you can secure it when you want it, a good place to carry it is on one of your waistcoat buttons. Proceed exactly as described above. When you place the pack on the table request a spectator to cut it about the middle and as you say, 'and put the top half here,' touch the table just to the right of the pack and deposit the pellet of wax. When the pack is cut, and the cut put at the spot you indicated, the wax pellet adheres to the face of the lowest card and therefore is carried to the back of the selected card when the cut is replaced. The two cards stick together, the squaring of the cards bringing their edges together, and the pressure exerted in the further cutting cements them still more securely. When you deal the double card it is apparent to the touch and you have only to push off the top card of the two and stop on the next. With proper presentation the trick becomes a little miracle.
