Modern Magic: A Practical Treatise on the Art of Conjuring

The person addressed will probably select one or other of the numbers named, but you must be prepared for the possibility of his naming a smaller number. If he says “Four,” you have only to ruffle the cards in your hand, or make any other gesture which may ostensibly effect the transposition; and he will find on examination that the cards under his hand are increased by four, according to his desire. If he says “Three,” you say, “Please give me back one card, to show the others the way.” This makes the number right. If “two” are asked for, you may ask for two cards to show the way; or you may say, “Two, very good! Shall I send a couple more for anybody else?” when some one or other is pretty sure to accept your offer. If one only is asked for, you must get two or three persons to take one each, taking care always by one or the other expedient to make the number correspond with the number you have secretly added. While the attention of the company is attracted by the counting of the cards, to see if you have performed your undertaking, again palm the same number of cards as was last selected (suppose three), and, after the cards are counted, gather them up, and give them to some other person to hold, adding to them the three just palmed; then taking that number of cards from the top of the pack, and again replacing them, say, “I will now send these three cards into your hands in the same manner.” Ruffle the cards, as before, and, upon examination, the number of cards in the person’s hands will again be found to be increased by three.
