You then take the card drawn, namely, the king of hearts, and
place it at the point corresponding to B in the above figure.
Finally, you take any two other cards, and place them at C and D.
Of course, the cards are placed face downwards.
After this location of the cards, you tell the party who has
chosen the card that you will change the position of the cards,
by pushing alternately that at the point A to B, and that at D to
C, and vice versa; and you defy him to follow you in these
gyrations of the card, and to find it.
Of course, seeing no difficulty in the thing, and believing with
everybody that his card is placed at the point A, he will
undertake to follow and find his card. Then performing what you
undertake to do, you rapidly change the places of the cards, and
yet slowly enough to enable the party to keep in view the card
which he thinks his own, and so that you may not lose sight of
the one you placed at B.
