Take
100
lbs.
of
white
sugar,
and
mix
with
it
3
gallons
of
water,
in
a
copper
or
iron
boiler
of
50
gallons
capacity.
It
is
necessary
to
have
the
boiler
this
size,
as
in
manufac-
turing
coloring
the
liquid
is
apt
to
run
over
when
made
in
a
smaller
vessel.
Put
the
boiler
on
a
smart
fire,
and
stir
the
sugar
constantly,
so
as
to
prevent
its
burning
on
the
bottom.
Keep
it
boiling
until
it
gets
as
black
as
tar
when
dropped
on
a
cold
stone.
Then
add
slowly
6{
gallons
of
boiling
water
at
firsts
only
a
little
at
a
time^
and
increas-
ing
the
quantity
gradually
—
constantly
stirring
as
the
whole
is
dissolved.
Pass
it
through
a
flannel.

the
process
of

;
after
which
add,
in
small
quantities,
\
lb.
of
chalk
powder,
and
con-
tinue
stirring
it
as
long
as
a
froth
rises
from
the
mixture.
After
having
done
this,
let
it
stand
for
24
hours,
then
de-
cant,
filter,
mix
1^
pint
of
alcohol
with
it,
and
