It is better to use court cards to place between the third and fourth kings, because if the cards should slip aside, they would not be so readily distinguished as common cards.

6. THE FOUR ACCOMPLICES.

Let a person draw four cards from the pack, and tell him to think of one of them. When he returns you the four cards, dexterously place two of them under the pack, and two on the top. Under those at the bottom you place four cards of any sort, and then, taking eight or ten from the bottom cards, you spread them on the table, and ask the person if the card he fixed on be among them. If he say no, you are sure it is one of the two cards on the top. You then pass two cards to the bottom, and drawing off the lowest of them, you ask if that be not his card. If he again say no, you take that card up, and bid him draw his card from the bottom of the pack. If the person say his card is among those you first drew from the bottom, you must dexterously take up the four cards that you put under them, and placing those on the top, let the other two be the bottom cards of the pack, which draw in the manner before described.

7. TO TELL THE CARD THOUGHT OF IN A CIRCLE OF TEN.

Place the first ten cards of any suit in a circular form, as in the annexed figure; the ace being counted as one. Request a person to think of a number or card, and to touch also any other number or card; desire him to add to the number of the card he touched the number of the cards laid out, that is, ten; then bid him count that sum backward, beginning at the card he touched, and reckoning that card at the number he thought of; when he will thus end it at the card or number he first thought of, and thereby enable you to ascertain what that was. For example, suppose he thought of the number three, and touched the sixth card, if ten be added to six, it will of course make sixteen; and if he count that number from the sixth card, the one touched, in a retrograde order, reckoning three on the sixth, four on the fifth, five on the fourth, six on the third cards, and so on; it will be found to terminate on the third card, which will therefore show you the number the person thought of. When the person is counting the numbers, he should not, of course, call them out aloud.

8. TO GUESS THE CARD THOUGHT OF.

To perform this trick, the number of cards must be divisible by 3, and it is more convenient that the number should be odd. Desire a person to think of a card; place the cards on the table with their faces downward, and, taking them up in order, arrange them in three heaps, with their faces upward, and in such a manner that the first card of the pack shall be first in the first heap, the second the first in the second heap, and the third the first of the third; the fourth the second of the first, and so on. When the heaps are completed, ask the person in which heap the card he thought of is, and when he tells you, place that heap in the middle; then turning up the packet, form three heaps, as before, and again inquire in which heap the card thought of is; form the three heaps afresh, place the heap containing the card thought of again in the center, and ask which of them contains the card. When this is known, place it as before, between the other two, and again form three heaps, asking the same question. Then take up the heaps for the last time, put that containing the card thought of in the middle, and place the packet on the table with the faces downward, turn up the cards till you count half the number of those contained in the packet; twelve, for example, if there be twenty-four, in which case the twelfth card will be the one the person thought of. If the number of the cards be at the same time odd, and divisible by three, such as fifteen, twenty-one, twenty-seven, &c., the trick will be much easier, for the card thought of will always be that in the middle of the heap in which it is found the third time, so that it may be easily distinguished without counting the cards; in reality, nothing is necessary but to remember, while you are arranging the heap for the third time, the card which is the middle one of each. Suppose, for example, that the middle card of the first heap be the ace of spades; that the second be the king of hearts; and that the third be the knave of hearts: if you are told that the heap containing the required card is the third, that card must be the knave of hearts. You may therefore have the cards shuffled, without troubling them any more; and then, looking them over for form's sake, may name the knave of hearts when it occurs.

9. TO TELL THE NUMBER OF CARDS BY THE WEIGHT.

Take a pack of cards, say forty, and privately insert among them two cards rather larger than the others; let the first be the fifteenth, and the other the twenty-sixth, from the top. Seem to shuffle the cards, and cut them at the first long card; poise those you have taken off in your hand, and say, "There must be fifteen cards here;" then cut them at the second long card, and say, "There are but eleven here;" and poising the remainder, exclaim, "And here are fourteen cards." On counting them, the spectators will find your calculations correct.
