Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
421
A
similar
apparatus
to
the
above
is
sometimes
made
in
metal,
and
of
a
size
sufficient
to
enclose
a
cannon-ball,
which
being
made
to
disappear,
its
place
is
supplied
by
a
variety
of
articles
which
have
been
otherwise
disposed
of
at
an
earlier
period.
THE
OBEDIENT
BALL.--This
trick
is
of
Japanese
origin,
and
from
that
circumstance
is
sometimes
known
as
the
Japanese
Ball.
It
is
performed
with
a
large
black
wooden
ball,
about
five
inches
in
diameter,
with
a
hole
bored
through
it
from
side
to
side.
A
piece
of
stout
rope,
four
or
five
feet
in
length,
with
a
knot
at
one
end,
completes
the
apparatus.
The
performer
commences
by
passing
the
rope
through
the
ball,
and
hands
both
for
examination.
The
ball
is
found
to
run
loosely
upon
the
rope,
and
both
are
manifestly
quite
free
from
mechanism
or
preparation.
The
articles
being
returned,
the
performer
places
his
foot
upon
the
knotted
end
of
the
rope,
and
taking
the
other
end
in
his
right
hand,
holds
it
in
a
perpendicular
position.
The
ball
is
raised
as
far
as
the
length
of
the
rope
will
admit,
and,
on
being
again
released,
immediately
runs
down
again,
as
would
naturally
be
expected.
The
performer
now
announces
that,
in
obedience
to
his
will,
the
laws
of
gravity
will
be
in
this
particular
instance
suspended.
Accordingly,
on
his
again
raising
the
ball
to
any
portion
of
the
rope,
it
remains
stationary
at
that
height
until
released
by
his
command,
when
it
instantly
runs
down.
Other
persons
are
invited
to
come
forward,
and
to
place
the
ball
at
any
height
they
please,
the
ball
again
remaining
stationary
until
released
by
the
word
of
the
operator,
when
it
slowly
descends,
stopping,
however,
in
its
course,
and
remaining
fixed
whenever
commanded
by
the
performer
to
do
so.
