Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
535
Again
he
brings
up
the
vase,
apparently
full
as
before,
but
really
having
only
a
mere
layer
of
berries,
of
the
depth
of
d,
at
the
top.
He
now
puts
on
the
cover,
the
well
in
which
again
forces
d
and
the
superposed
layer
of
coffee-berries
down
to
make
way
for
it,
and
causes
the
crook
again
to
catch
beneath
the
hollow
of
the
foot.
The
same
operation
is
now
gone
through
with
the
vase
whose
well
contains
the
sugar,
and
the
box
of
white
beans.
The
performer
lastly
takes
from
the
third
vase
a
handful
of
bran,
which
he
scatters
to
show
its
genuineness,
and
then
places
the
cover
over
it.
The
trick
is
now
really
completed.
On
removing
the
respective
covers
(taking
care
of
course,
first
to
turn
the
bayonet-catches
in
the
right
direction),
the
wells
are
released
from
the
covers
and
locked
to
the
vases,
which
are
thus
found
full
respectively
of
hot
coffee
and
sugar,
and,
on
removing
the
cover
of
the
third
vase,
the
bran
is
lifted
off
with
it,
and
the
milk
is
revealed.
Some
coffee
vases,
and
more
particularly
those
of
French
make,
dispense
with
the
bayonet-catch,
replacing
it
by
a
peculiar
arrangement
inside
the
top
of
the
cover.
The
upper
edge
of
the
well
is
slightly
turned
in
all
round,
and
the
turning
of
the
knob
at
the
top
of
the
cover
causes
three
flat
bolts
or
catches
to
shoot
out
circularly
from
the
edges
of
a
hollow
disc,
soldered
to
the
top
of
the
cover
inside,
and
insert
themselves
under
this
projecting
edge.
(See
Figs.
224,
225.)
The
mechanical
arrangement
by
which
this
is
effected
is
almost
impossible
to
explain
in
writing,
though
it
becomes
readily
intelligible
upon
an
actual
inspection
of
the
apparatus,
and
will
be
understood
without
much
difficulty
after
a
slight
study
of
the
above
diagrams,
the
arrow
in
each
case
indicating
the
direction
in
which
the
knob
must
be
turned,
in
order
to
bring
the
bolts
into
the
condition
shown
in
the
opposite
diagram.
