the performer, he takes one, shuffles it
well, and lets a party take a card. He then takes the other, shuffles
it, and lets another party take a card. Then, whilst each party
is looking at his card, which HE IS REQUESTED TO DO, the performer
dexterously changes the place of the two sets, and he requests the
parties to replace the cards in the set whence they took them. It
follows that the party who took a card from the EVEN set places it in
the ODD set, and he who took it from the ODD set places it in the even
set. Consequently, all the shuffling and cutting in the world will be
useless, for the performer has only to spread out the cards of each set
to point out the cards drawn.

10. Singular arrangement of sixteen cards.

Take the four kings, the four queens, the four knaves, and the four tens
of a pack, and ask if there be any one in the company who can form a
square with them in such a manner that, taken in any direction, from
right to left, from the top to the bottom, by the diagonal--anyhow, in
fact--there will always be in each line a king, queen, knave, and a ten.
Everybody will think the thing easy, but it is certain that no one will
succeed in doing it. When they 'give it up,' take the sixteen cards and
arrange them as shown, when the king, queen, knave, and ten will stand
as required.

11. The seven trick.

Make up the four sevens of a pack, and take seven other cards, no matter
which, for another lot, and, presenting both lots, you say:--Here are
two lots totally dissimilar; nevertheless, there is one of seven, and
I declare it will be the first touched by any party present. Of course,
when touched, you at once prove your words by exhibiting either the
sevens or the seven cards--taking care to mix the cards into the pack
immediately to prevent detection.

12. Infallible method for guessing any number that a party has thought
of.

Take the first ten cards of a pack of 52 cards. Set out these ten cards
as shown below, so that the point A should correspond to the ace, and to
1--the point F to the card representing the 6--and E to the 10.

B C D
1 A--------E 5
10 K--------F 6
I H G

Thus prepared, you request a party to think of a card, and then you tell
him to touch any number he pleases, requesting him to name it aloud.
Then, adding the whole number of the cards to the number touched, you
tell him to co
