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.
