Address an envelope for each of the above, using the following as a model.
Exercise 218—Cautions
The Heading
Always date your letters.
Give your full address, even if you are certain that the one to whom you are writing knows it.
The Introduction
The person addressed must always be given a title. If you address one man, use Mr.; if a firm, use Messrs.; if a woman, Miss or Mrs. If a man has a title like Professor or Doctor, it should be used, and Mr., of course, omitted.
Hon. (Honorable) is used for a person who holds, or who has held, a public office. It is a very formal title.
Esq.(Esquire) is a legal form used by some correspondents in addressing any man. It is an English usage. It always follows the name, and, if it is used, Mr. is omitted. In this country Mr. is preferable.
