EFFECT :
The magician takes eleven cards, A to J inclusive, and
holds them face down. He slaps the packet twice and turns up the
top card, it is an A. He puts the next card under the others. He
turns up the new top card, it is the deuce. Proceeding in the same
way, one card dealt face up, the next one placed under the others,
the cards come out in order from A to J.
Picking up the packet the
magician slaps it once and repeats the same deal, but this time
only the odd cards come out in rotation. Again he deals as before
but without slapping the packet and the cards come out hopelessly
mixed. He hands the packet to a spectator and he deals them in
the same way but again they are mixed up. Taking the packet
once more the magician slaps it twice and deals them as before,
one out and one under, and the cards come out in proper rotation
from A to J.

HOW IT'S DONE....
The eleven cards must be arranged thus: A, 9, 2, 7, 3, J,
4, 8, 5, 10, 6. Following the system of dealing one card and
placing the next on the bottom this rotation brings the cards out in
order, A to J and after three repetitions they are automatically
brought back to their original order. Instead of the slap any mystic
incantation may be used. The cards should be placed in order
secretly at the top of the pack and a false cut made so that they
appear to be taken at random.
