If many letters are written it will be convenient to have the
permanent address of the writer printed.

The writing should be plain, and there should be no doubt in the
mind of the reader as to the proper spelling of the address and
signature.

Avoid the hieroglyphics which some vain men adopt in signing their
names. It may be fanciful, but it does not imply consideration for
the time and patience of strangers.

The following forms will serve to illustrate the type of heading
used in ordinary business letters:

1

124 Smith St., Brownsville, Mass.

Mr. John Smith,
Doylestown, Penna.
Dear Sir:

2

Leroy, Mass.,
September 5, 1910.
Messrs. Brown and Jones,
Denver, Col.
Gentlemen:
