To
those
who
do
not
find
the
following
useful
in
its
details
for
their
own
use,
I
express
my
congratula-
tions
and
esteem
as
a
business
associate.
To
those
who
do
find
it
a
guide
I
wish
to
express
my
assur-
ance
that
they
will
find
this
work
an
absolutely
and
indispensably
correct
one
to
work
by,
provided
they
understand
and
practice
it.
You
may
travel
all
over
the
country,
and
you
will
find
my
practice
a
good
one.
In
discharging
your
duties
you
will
find
many
little
hints
you
will
not
be
able
to
practice
for
not
having
the
facilities
to
do
so,
but
I
may
say
I
have
at
least
shown
you
how
it
ought
to
be
made
and
executed.
It
must
be
left
to
your
own
judgment
to
follow
the
directions
given
herein the
best
way
you
know
of,
and
leave
out
what
ought
to
be
left
out,
because
your
position
does
not
offer
you
the
oppor-
tunity.
I
have
mentioned
in
this
work
everything
that
is
necessary
for
a
theoretical
experience.
It
should
be
borne
in
mind:
Not
everybody
can
advance
so
as
to
be-
come
an
artist
in
tending
bar,
but
we
all
should
learn,
and
try to
improve
by
all
means
that
are
offered.
I
am
far
from
believing
it
possible
to
become
a
practical
man
by
simply
studying
this
book,
but
while
doing
so,
you
will
get
an
essential
and
true
idea
of
how
to
become
