MANUFACTURE
OF
VINEGAR.
Glass
tubes
are
employed,
instead
of
the
canes
just
alluded
to,
but
they
are
rarely
found,
and
the
cane
ones
will
answer
every
purpose.
The
next
process
consists
in
packing
or
chargin
a
the
generators
;
and
this
consists
in
simply
filling
the
generator
to
within
four
or
six
inches
of
the
top,
with
beech
chips
and
shavings.
These
two
articles
are
to
be
of
no
peculiar
shape
;
as
they
fall
from
the
axe
and
plane,
under
ordinary
circumstances,
are
the
kind
that
are
made
use
of.
The
chips
and
shavings
should
not
be
packed
too
solid
or
densely,
as
this
would
prevent
the
free
circulation
of
the
air
;
neither
should
the
chips
be
packed
too
solid,
in
the
vicinity
of
the
holes
in
the
sides
of
the
generator.
The
generator
being
filled
as
described,
a
head
is
to
be
fitted,
and
is
to
rest
on
the
chips.
This
head
is
to
be
made
in
the
same
manner
as the
false
bottom,
viz.
in
having
one
hole
to
every
square
inch
of
the
head.
Each
one
of
these
holes
is
to
have
a
piece
of
packthread,
two
or
three
inches
in
length,
unra-
velled
at
one
end,
and
with
a
knot
tied
on
the
other
ci
d.
This
knot
prevents
the
packthread
from
slip-
ping,
or
being
forced
through
the
holes,
and
the
other
end
being
unravelled,
assists
in
a
degree
iu
minutely
separating
the
particles
that
form
the
liquid
that
is
to
be
acetified.
The
liquid
by
falling
on
thia
head
spreads
uniformly
throughout
the
rna^s
of
chips.
