Modern Magic: A Practical Treatise on the Art of Conjuring

This same effect will be produced with any number of cards, so long as such number is odd, and a multiple of three. The process and result will be the same, save that if fifteen cards are used each heap will consist of five cards, and the third card of each will be the middle one; if twenty-seven cards, each heap will consist of nine cards, and the fifth will be the selected one, and so on. Third Method.--Take any number of the cards, and deal them face upwards upon the table, noting in your own mind the first card dealt. Ask any number of persons each to note a card, and to remember at what number it falls. When you have dealt all the cards you first took in your hand, take them up again, without disturbing their order, and turn them face downwards. In order to show that the trick is not performed by any arithmetical calculation (you should lay great stress upon this, the fact being precisely the reverse), invite the company to take any number they choose of the remaining cards (such number being unknown to you), and place them either above or below the cards you have dealt. Allow the cards to be cut (not shuffled) as many times as the audience please. You now, for the first time, ask each person what was the number of his card, and, on being informed, again deal the cards, turning them face upwards. When the original first card appears, count on (silently) from this as number one to the number mentioned, at which number the noted card will again appear. Should the whole of the cards be dealt out without reaching the required number, turn the cards over again, and continue from the top of the pack until that number is reached.
