The affectation of a handwriting which enables you to put but few words on a page, is absurd and vulgar in the extreme. Yet, on the other hand, a too delicate or minute hand is not desirable. Legibility, neatness, and clearness are the salient virtues of a letter.
The use of the typewriter is confined to business. It is still very bad form to use it for personal letters; but should elegant script and small, clear forms of type, such as are furnished by one or two of the machines now on the market, be in common use, there is little doubt but what the speed of service and the advantages of clearness would bring the typewriter into use in intimate, and perhaps at last into more formal, social correspondence. The tendency seems to lie in that direction.
Sealing, Stamping, and Directing Envelopes
Neatness is especially necessary in the folding of letters, and in addressing, stamping, and sealing the envelopes. Haste and slovenliness here take away the suggestion of compliment in the courtesy of the note, and are as insulting as any rudeness of manner can well be.
The fastidious and leisurely still seal their envelopes with wax, imprinting thus their monogram. The well-gummed envelope now in vogue makes this superfluous for the ordinary informal letter. Addresses should be written with an eye to legibility, and the stamp should be affixed to the upper right-hand corner of the envelope with care and neatness. Social invitations, although engraved and therefore containing no handwriting, should always be sent with letter postage.
Letters should be plainly and completely addressed to insure their safe and prompt delivery.
Persons who have a large business correspondence should use for it envelopes on which their name and post office address are printed in the upper left-hand corner. In social correspondence these should be clearly written or engraved upon the back of the envelope.
Sometimes where a business firm is small or little known, it facilitates the delivery of a business letter to place the number of the office room in a building upon the envelope. Where, however, the firm is so large that probably the entire mail is carried from the post office in bags, or where a post office box is doubtless made use of instead of the carriers' delivery, even the street number is superfluous. Letters for departments should be so marked.
If the city is one of the largest in the country, the name of the state is not added; as, New York City, Boston, Chicago, and Philadelphia would stand alone.
Only a business letter should have the word "City" in place of the name of the city, and it is better to write the name, omitting, if you choose, the state. This is permissible only when the central post office is used, as the postmark of any suburban station might cause confusion, and railway post office clerks, especially, should not be expected to guess accurately the intents of a writer.
