Modern Magic: A Practical Treatise on the Art of Conjuring

This trick, which appears marvellous in execution, is really very simple, and depends for its effect, not so much on any extraordinary degree of dexterity, as on the manner and address of the performer. When the four cards are replaced in the middle of the pack, the performer makes the pass to bring them to the top, and palms them. He then hands the pack to be shuffled. When it is returned, he replaces them on the top, and, placing the person assisting him on his left hand, and facing the audience, places the pack in the left breast-pocket of such person, taking care to place the top of the pack (on which are the chosen cards) outwards. In asking the names of the drawn cards, he puts the question first to the person who last replaced his card (and whose card is therefore on the top), and so on. He is particular in impressing upon the person assisting him that he must draw out the card as quickly as possible, thus giving him no time to select a card, but compelling him, so to speak, to take that which is readiest to his hand, which will always be the outermost, or top card.
