Form three ranks of five cards each, and request a party to think of one of these cards, and tell you in which rank it is. Take up the cards of the three ranks, taking care to place the cards of the ranks in which is the card thought of between those of the two other ranks. Make three more ranks as before. Ask the party again in which rank the card is, and take them up, placing the rank in which the card is between the two others. Operate in like manner a third time, and the card thought of will infallibly be the THIRD of the rank named by the party. Observe, however, you must not form each rank with five consecutive cards; but you must place the cards one by one, placing one successively in each rank; thus, one at the top on the left of the first rank, one below that first for the second rank, one below the second for the third rank, then one in the first, one in the second, one in the third, and so on. This trick, which is very easy, always produces a great effect. It only requires a little attention, and it can never fail unless you make a mistake in arranging the cards, which, however, is too simple to admit of error. 9. Two persons having each drawn a card from a pack, and having replaced them, to tell these cards after the pack has been shuffled and cut by the spectators as often as they like. The cards may be easily divided into two numerical parts, even and odd: by taking a king for four points, a queen for three, a knave for two, and the other cards for their especial points, we may make up two sets of sixteen cards each, the even composing one, and the odd the other. These two sets being before the performer, he takes one, shuffles it well, and lets a party take a card. He then takes the other, shuffles it, and lets another party take a card. Then, whilst each party is looking at his card, which HE IS REQUESTED TO DO, the performer dexterously changes the place of the two sets, and he requests the parties to replace the cards in the set whence they took them. It follows that the party who took a card from the EVEN set places it in the ODD set, and he who took it from the ODD set places it in the even set. Consequently, all the shuffling and cutting in the world will be useless, for the performer has only to spread out the cards of each set to point out the cards drawn. 10. Singular arrangement of sixteen cards. Take the four kings, the four queens, the four knaves, and the four tens of a pack, and ask if there be any one in the company who can form a square with them in such a manner that, taken in any direction, from right to left, from the top to the bottom, by the diagonal--anyhow, in fact--there will always be in each line a king, queen, knave, and a ten. Everybody will think the thing easy, but it is certain that no one will succeed in doing it. When they 'give it up,' take the sixteen cards and arrange them as shown, when the king, queen, knave, and ten will stand as required. 11. The seven trick.
