Modern Magic: A Practical Treatise on the Art of Conjuring

TO “FORCE” A CARD.--By this phrase is signified the compelling a person to draw such card as you desire, though he is apparently allowed absolute freedom of choice. Your first step is to get sight of the bottom card, or, if you want to force a predetermined card, to get that card to the bottom. Having done this, take the pack in the left hand, and insert the little finger half-way down, in readiness to make the pass. Make the pass by the first method, but, before uniting the two halves of the pack in their new position, again slip the little finger of the left hand between them. (The two halves will now be united at the end which is towards the spectators, but divided by the little finger at the end nearest to yourself; and the original bottom card, which is the one you desire to force, is now the bottom of the top heap, resting on the little finger.) Using both hands, with the thumbs above and the fingers below the pack, spread out the cards fanwise from left to right, at the same time offering them to the person who is to draw, and requesting him to select a card. Keep the little finger of the left hand still on the face of the card to be chosen, or you may now use, if more convenient, the same finger of the right hand, both being underneath the cards.
