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.
