Modern Magic: A Practical Treatise on the Art of Conjuring

Second Method.--(With both hands).--Holding the pack in the left hand, as directed for the first method, grasp as before the lower portion of the pack lengthways between the second finger at the upper end and the thumb at the lower end; move the left thumb, which now takes no part in the operation, a little below the pack to be out of the way. Then slide the lower half of the pack a little to the left, and the upper half to the right till they just clear each other (see Fig. 4), when you will be enabled to place what was originally the upper half undermost, and vice versâ. This is the theory of the process, but in practice the necessary motions are not nearly so distinct. As you grow more and more expert, the necessary movement from right to left should become gradually smaller and smaller, until at last it is almost imperceptible. You must study to reduce this movement to the very minimum; and in order to do this, endeavour, after you have once seen clearly what it is you have to do, to keep the hands together as much as possible. Let the edge of the palm of the right hand rest gently, but firmly, on the first three fingers of the left hand, and let the contact thus made form a kind of hinge or fulcrum for the movement of the hands. When you become expert, you will find that the mere outward movement of the two hands upon this imaginary hinge (the cards being held lightly, and allowed to accommodate themselves to the movement) is sufficient to produce the effect.
