To let a person think of a card that they see as you run them over; and then to make that person place the card they are thinking of in their pocket without knowing it.
Hold the deck squarely in the palm of the left hand in such a manner that you can bend the cards toward you with the fingers of the right hand, then let them slip back easily one at a time, but very fast, being careful to stop or hesitate on one card longer than the rest; in that way you impress that One card on the person’s mind, and it becomes the card they are thinking of.
And, of course, by watching closely you know the card even better than the person with whom you are doing the trick.
Next get the card that they have seen to a position fourth from the top.
You then place cards in left hand again with their face toward the person with whom you are doing the trick, and with the thumb of your right hand you lightly slip up the top card so the person can see its face, and ask if that is their card, to which they, of course, answer “No.” You then draw the card off the deck (backward) and showing it to them for the second time ask them if they are sure it is not their card, and at the same time ask them to place it in their pocket. Repeat the same operation with the next card, showing the person this card twice also.
By the time they have placed the second card in their pocket they will have about made up their mind that they have you stuck, which impression it is well to give them also in your talk, such as half admitting that you may have made a mistake.
But after you have shown him the third card, instead of handing him that one, let the thumb drop on the next card underneath (which you know is his card), and as you draw the card back that you have just shown him, you draw out and hand him the card he is thinking of–this time without showing it to him the second time and which he will invariably put in his pocket without looking at it.
After he has the card in his pocket you can carry him along as far as you like.
