The Ladies' Book of Etiquette, and Manual of Politeness

Without the ability to practice the refined art of epistolary correspondence, men would become cold and discordant: an isolated compound of misanthropy. They would fall off in forsaken fragments from the great bond of union which now adorns and beautifies all society. Absence, distance, and time would cut the silken cords of parental, brotherly, and even connubial affection. Early circumstances would be lost in forgetfulness, and the virtues of reciprocal friendship "waste their sweetness on the desert air." Since, then, the art and practice of letter-writing is productive of so much refined and social happiness, a laudable indulgence in it must ever be commendable. While it elevates the noble faculties of the mind, it also chastens the disposition, and improves those intellectual powers which would otherwise remain dormant and useless. Notwithstanding the various beauties and pleasures attendant upon the accomplishment, yet there are many who have given it but a slight portion of their attention, and have, therefore, cause to blush at their own ignorance when necessity demands its practice. There is no better mode by which to test the acquirements of either a young lady or gentleman than from their letters. Letters are among the most useful forms of composition. There are few persons, who can read or write at all, who do not frequently have occasion to write them; and an elegant letter is much more rare than an elegant specimen of any other kind of writing. The more rational and elevated the topics are, on which you write, the less will you care for your letters being seen, or for paragraphs being read out of them; and where there is no need of any secrecy, it is best not to bind your friend by promises, but to leave it to her discretion.
