Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
202
These
card-boxes
are
frequently
worked
in
pairs,
as
follows:--The
boxes
are
prepared
by
placing
a
different
card
secretly
in
each,
say
an
ace
of
hearts
in
the
one,
and
a
knave
of
spades
in
the
other.
The
performer
brings
them
forward
to
the
company,
each
hanging
wide
open,
and
held
by
one
corner
only,
with
the
first
and
second
finger
inside,
and
the
thumb
outside
the
box,
taking
care,
however,
to
hold
each
by
the
side
containing
the
false
bottom,
which
is
thus
kept
in
position
by
the
pressure
of
the
fingers.
So
held,
the
boxes
appear
absolutely
empty.
Having
drawn
attention
to
the
entire
absence
of
any
preparation,
the
performer
lays
them
open
upon
the
table,
and,
taking
up
a
pack
of
cards,
requests
two
of
the
company
each
to
draw
one.
They,
of
course,
imagine
that
they
are
making
a
free
choice,
but
in
reality
he
forces
(either
by
sleight-of-hand,
or
by
means
of
a
forcing
pack)
the
ace
of
hearts
and
the
knave
of
spades.
Again
bringing
forward
the
two
boxes,
he
requests
each
person
to
place
his
card
in
one
of
them,
taking
care
so
to
arrange
that
the
person
who
has
drawn
the
ace
of
hearts
shall
place
it
in
the
box
already
containing
the
concealed
knave
of
spades,
and
vice
versâ.
Closing
each
box
with
the
portion
containing
the
false
bottom
uppermost,
he
now
announces
that
at
his
command
the
cards
will
change
places,
which,
on
re-opening
the
boxes,
they
appear
to
have
done.
By
again
turning
over
the
boxes,
they
may
be
made
to
return
to
their
original
quarters.
