Easy card Tricks for Beginners - To Tell Chosen Cards

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 person take a card. He then takes the other, shuffles it, and lets another person take a card.
Then, whilst each person is looking at his card, which he is requested to do, the performer dexterously changes the place of the two sets, and he requests them to replace the cards in the set whence they took them.
It follows that he 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.
