RECEIPTS.
scarlet,
purple,
and
some
other
colours.
If
any
article
is
directed
to
be
alumed,
be
careful
to
rid
it
well of
the
soap-suds,
as
alum
turns
soap
to
grease.
When
the
article
is
put
in
the
alum-liquor,
it
is
to
be
well
dipped
in
and
out
and
opened,
to
receive
this
preparation
more
equally',
for
an
hour,
or
all
night,
if
circumstances
admit;
and,
when
alumed,
it
must
be
well
wrung
out
and
rinsed
in
two
waters,
and
then
djed,
the
sooner
the
better,
before
getting
dry.
Note.
—
The
aluming
of
silks
ought
to
be
done
cold,
or
it
will
be
deprived
of
its
lustre.

Preparing
of
the
Dye-Liquors,
or
Scalding
the
Wood.
Having
something
like
the
end
of
a
tub,
about
one
foot
deep,
with
a
copper
bottom,
bored
full
of
holes
about
a
quarter
of
an
inch
in
diameter,
lay
a
piece
of
rather coarse
sheeting
on
this
;
lay
it
all
together
on
another
tub
;
fill
it
with
the
wood
to
be
scalded.
Then,
having
a
copper
boiler
full
of
boiling
water,
fill
the
tub
which
contains
the
wood
with
boiling
water;
stir
it
during
the
time
it is
going
through;
fill
it
up
again,
and
so
repeat
the
operation
till
you
have
got
all
the
strength
from
the
wood.
The
criterion
by
which
to
know
when
the
strength
is
gone
from
the
wood
is
the
paleness
of
the
liquor
as
it
runs
through.
This
operation
is
considered
superior
to
boiling
the
wood
in
a
copper
boiler,
especially
for
the
ground
wood
:
but
either
v/ay
will
answer.
The
method
of
rendering
the
liquor
stronger
of
course
is
by
evaporation,
in
a
copper
vessel,
with
a constant
fire
under
it.
