folded over just before.

In case a check, note, draft, bill or currency is to be sent by
letter, it should be placed on the upper half of the sheet as it lies
open, and then the letter should be folded the same as if it were not
there. This will fold the paper or document in the letter so that it
will be difficult to extract it while being transmitted in the mails,
and so that it will not be dropped or lost in opening the letter.

The letter is now folded so that it will be of equal thickness in
every part of the envelope. Insert the last broken or folded edge in
the envelope first, with original edges of the sheet at the end of
the envelope which the stamp is on; when taken from the envelope the
letter will then be proper side up.


THE LITERATURE OF A LETTER.

To be able to compose a letter requires more ability than to give it
the proper arrangement and mechanical dress. A mind well stored with
useful knowledge as well as command of language, is necessary in
writing a letter on general subjects. The strictly business letter
requires a thorough understanding of the facts concerning which
the letter is written, and these facts to be set forth in plain and
unmistakable language. All display of rhetoric or flourish of words is
entirely out of place in the sober, practical letter of business. The
proper use of capital letters, punctuation, and correct spelling
are essential to the well written letter, and with a little care and
striving may be easily acquired.
