seven, which will be
your thirteenth tap, which number added to seven, the number thought of,
will make twenty, and your friend will say "Stop."

Another effective trick can be worked with the card dial, but it
requires the assistance of a confederate. Having previously instructed
him what to do, you tell the company that any one is at liberty to touch
one of the cards during your absence from the room, and on returning you
will indicate the card he has touched. Upon your returning hand a pencil
to your confederate and request him to touch the cards in rotation until
you say "Stop," when the pencil will rest on the right card. Your
confederate must hold the pencil in his right hand with his forefinger
resting on top. When he touches the right card he must raise that finger
slightly. It is a signal no one would notice, and the trick always
creates a great deal of wonder.

HOW TO GUESS CARDS THOUGHT OF

Allow the pack to be shuffled freely and then place it on the table face
down. Take the three top cards, and holding them up with their backs
towards you, ask some one to think of one. Then spread them face down on
the table in front of you. Take three more cards, and ask a second
person to think of one, and lay these on top of the other three. Show
three more cards to a third person, and after he has thought of one, lay
these on top of the others. You have now three parcels on the table,
each containing three cards. Hold up one parcel, and say to each person:
"Is the card you thought of in this lot?" Proceed in the same way with
the other parcels, and then tell each person the name of the card he
thought of. As the cards shown to the first person were laid on the
table first, it stands to reason that the cards he thought of must be at
the bottom of the parcel he has said "Yes" to; the second person's card
will be the middle one in the parcel, and the third person's the top
card.

AN INGENIOUS CARD TRICK

Select ten cards, regardless of suit, the ace, and from deuce to ten,
arranging them as follows: Lay the ten face down on the palm of your
hand, the nine next, and the others in rotation, finishing with the ace,
which you call "one." Give the cards so arranged to a friend, and tell
him you will leave the room while he moves cards one at a time, not to
exceed nine, from top to bottom, and when you return you will tell him
how many he has shifted. You may repeat this feat successfully several
times, and finish by
