The heading of a letter includes the address of the writer and the date of the writing. When numerous letters are sent from one place to another, the street and number may after a time be omitted from the heading. Example (5) illustrates this. A son living in Boston has written to his mother frequently and no longer considers it necessary to write the street and number in every letter. If there is any doubt in the writer’s mind as to whether his address will be remembered or not, he should include it in the letter. If the writer lives in a small place where the street and number will not be needed in a reply sent to him, it is unnecessary for him to make use of it in his letter. When the street and number are omitted, the heading may be written on one line, as in example (5), but the use of two lines is preferable.
Custom has decreed that the proper place for the heading is in the right-hand upper corner of the first page. Sometimes, especially in business letters, we find the writer’s address at the close of the letter, but for the sake of convenience it is preferably placed at the beginning. The first line should be about one inch and a half from the top of the page. The second line should begin a little to the right of the first line, and the third line, a little to the right of the second line. Attention should be paid to proper punctuation in each line.
In a comparatively few cases we may find that the omission of the date of the letter will make no difference to the recipient, but in most cases it will cause annoyance at least, and in many cases result in serious trouble both to ourselves and to those who receive our letters. We should not allow ourselves to neglect the date even in letters of apparently no great importance. If we allow the careless habit of omitting dates to develop, we may some day omit a date when the omission will affect affairs of great importance. This date should include the day, month, and year. It is better to write out the entire year, as 1905, not ’05.
In business letters it is customary to write the address of the person or persons addressed at the left side of the page. Either two or three lines may be used. The first line of this address should be one line lower than the last line of the heading. Notice examples (1), (3), and (6). When the address is thus written, the salutation is commonly written one line below it. Sometimes the salutation is commenced at the margin, and sometimes a little to the right of the address. Where there is no address, the salutation is written a line below the date and begins with the margin, as in examples (2), (4), (5), and (7).
