ck?" Answer, "Fifty-two." "How many suits?" "Four." "What are their
colours?" "Red and Black." "Now name one of those colours." "Red." If he
should say "black," you must say, "You select black so I take red. How
many suits are there in red?" "Two." "What are they?" "Hearts and
Diamonds." "Name one of those suits quickly." "Hearts." If he should
name diamonds say, "Then I take hearts." "How many cards in the suit?"
"Thirteen." "How many between the ace and knave?" "Nine." "How many
below six and how many above six?" "Four below and four above." "Name
either below or above?" "Below." If he says "above," say, "That gives me
those below six. What are the numbers below six?" "Two, three, four, and
five." "Name two of those numbers." "Four and five." If he should say
"two and three," or "three and four" you remark, "That leaves me four
and five. Name one of those numbers." If he says "four," you say, "Which
leaves five. The suit you selected was hearts, and now we have come down
to five. So you have actually selected the five of hearts; and I am sure
you will admit I have not influenced your choice in any way. Please turn
over the card on the table." He does so and, of course, finds it is the
five of hearts.

THE CLOCK

Select twelve cards of any suit, ace to ten and king and queen; arrange
them in a circle to represent the figures on the face of a clock, the
king as twelve and the queen as eleven (Fig. 3), and request a member of
the company to think of one of the numbers. You then explain you will
tap the cards with a pencil and he is to mentally add your first tap to
the number he thought of and count your succeeding taps until twenty is
reached, when he is to call "Stop," and your pencil will then rest upon
his number. For instance, we will suppose he thinks of twelve; he must
count your first tap as thirteen and continue counting mentally until
twenty is reached.

EXPLANATION.--Touch the cards at random during the first seven taps and
allow your pencil, on its eighth tap, to rest on the king (twelve).
Eight and twelve being twenty he will of course say "Stop." Supposing he
thought of a lower figure--seven, for instance. Tap at random as before
until your eighth tap, which must always be on twelve; then touch the
cards in rotation, making the queen your ninth tap, the ten your tenth
tap, nine your eleventh, and so on until you reach
