deprive
the
spent-wash,
as
much
as
possible,
of
the
sugar
which
it
retains
after
the
first
operation,
and
to
effect
this
to
the
advantage
of
the
alcohol.
This
mode,
which
is
only
practicable
in
distilleries
in
which
the
preparation
of
wine
is
continuous,
would
almost
leave
in
the
spent-wash
the
only
substances
which
do
not
directly
concur
to
the
formation
of
alcohol
y
and
in
gene-
ral
this
spent-wash
is
wasted
on
leaving
the
still.
However,
it
might
be
possible
to
turn
it
to
advantage,
in
many
instances,
as
manure
;
and
if
the
acids
which
they
retain
did
not
suit
the
nature
of
the
soil
for
which
they
were
intended,
they
might
be
neutralized
by
means
of
lime.
It
is
a
fact
that
the
organized
substances
which
it
retains
would
be
most
useful
to
vegetation.
It
would
be
necessary
to
calculate,
in
such
application,
whether
the
effects
of
such
a
manure
would
sufficiently
indemnify
the
farmer
for
his
expenses
in
carriage
and
iu
labour
which
it
would
occasion
:
I
am
of
the
opinion
that
it
would
not.
Some
remarks
will
now
be
made
on
the
distillation
of
half-fluid,
half-solid
matter.
Wines
of a
semi-fluid,
semi-
solid
nature
may
be
very
numerous,
though,
in
fact,
they
are
less
so
than
fluid
wines.
The
most
remarkable,
and
those
which,
by
their
importance,
solicit
a
more
particu-
lar
attention,
are
lees
or
ground
wines,
worts
of
grain
and
of
potatoes,
which
have
not
been
mashed
by
extraction.
Every
means
of
perfection
applied
to
any
of
these
wines
is
applicable
to
all
of
them,
and
in
this
respect
we
might
generalize
what
will
be
said
on
this
subject;
but,
on
the
other
side,
there
is
this
difference,
that
the
wines
of
grain
and
of
potatoes
may
more
easily
and
