Ask some one to shuffle the pack, and, on receiving it back, glance at
the bottom card. Put the pack behind your back, and then turn the top
card round with its face toward you; bring the pack in front of you, the
bottom card facing the audience and the turned card facing you. Having
already glanced at the bottom card, you can tell them its name, and you
now know the card on top. Put the pack behind you again, and move the
top card to the front, and turn the one now on top round. Again hold the
pack up and name the front card, at the same time noting the card facing
you. By repeating this process you can name all the cards in the pack.
Take care to have all your audience in front of you, or the turned card
will be seen.
