“ Nature's chief masterpiece is writing well. A letter, business or social, is simply talk upon paper. And as a wise philosopher once said, "Never put on paper what you would not care to see printed in the newspaper for all to read." As in everything else connected with the social world, ease is absolutely essential to the correct letter. The style must not be cramped, stilted, forced. A free and easy flow of language, simple and understandable, and with just that acceptable degree of cordiality and heartiness that makes one enjoy reading, is essential in all correspondence. ”
