Letter writing is a high art, and can give great pleasure to one's friends. It must not, however, be intemperately indulged in, either in frequency, length of letters, or freedom of expression. A timely note is a great binder of friendship, and may give comfort and satisfaction much greater than a longer letter at a less important moment.
The danger of letter writing is that one is tempted to pour out one's inmost feelings with thoughtless abandon, and find later that the relative or friend to whom the letter was addressed was unworthy of the confidence, or, if not unworthy, was repelled by it, or indiscreet in guarding it. It is always wise for one to restrain his expression of himself, when writing or speaking, within the bounds of dignity and a self-respecting reserve.
The classic letters of literature are usually those the fervor of expression and self-revelation of which gave them a strong human interest, but in the preservation and publication of which sacred confidence was violated. The average letter of the average man or woman is by no means a classic, or worthy of preservation. It should be destroyed when it has fulfilled the immediate purpose for which it was written. It may otherwise sometime be instrumental in bringing ridicule, if not shame, upon the unsuspecting writer.
As letter writing is the most common form of composition, the general rules pertaining to that art should be observed in even the most informal of letters.
All letters should be concise and definite. An involved style is a great waste of time and mental power, and has no advantage.
A letter should be written on consecutive pages, unless it be very short, in which case it is preferable to use the first and third, rather than only the first and second, pages. It should never be written so that the sheet has to be turned around and the pages read at different angles. The turning over of the pages should be all that is necessary.
If, however, social note paper is used for a short business letter to a business man, open the sheet out flat, turn it so that the left side becomes the top of the sheet, and use as you would a single large sheet of commercial paper. This enables the reader to see the whole matter at a glance.
Do not scrawl your letter over the page; but do not, on the other hand, appear to economize in paper. Make the place and date lines clear and distinct. Set off the salutation from the body of the letter, and make the form of the letter upon the page artistic and concise. Paper is cheap, and the delight of receiving a letter well framed in even margins and written on regular, if invisible, lines is a pleasure easily afforded a friend.
The letter should be begun about two inches down from the upper edge of the paper. The left-hand margin should be three-quarters of an inch, with paragraph indention an inch more. The lower margin also should be three-quarters of an inch, and the right margin should be kept even and, for best effect, almost as wide as the left margin.
Do not run on the letter without paragraphing it, but place each subject in a paragraph by itself.
