He sends fifty such communications where his father would have written three letters, and his grandfather one slowly composed and slowly travelling epistle. Many modern correspondents appreciate the convenience of the post-card, but their conscience, as that of well-bred people, cannot get over the fault of its publicity. For these the stationers have devised several different substitutes. There is the French plan of what is called "Un Mot à la Poste," a piece of paper with a single fold, gummed round the other three edges, and perforated like postage-stamps for the facility of the opener.[31] There is the miniature sheet of paper that you have not to fold, and there is the card that you enclose in an envelope, and that prepares the reader for a very brief communication. Here, again, is a very curious illustration of the sacrificial nature of courtesy. A card is sent; why a card? Why not a piece of paper of the same size which would hold as many words? The answer is that a card is handsomer and more costly, and from its stiffness a little easier to take out of the envelope, and pleasanter to hold whilst reading, so that a small sacrifice is made to the pleasure and convenience of the receiver, which is the essence of courtesy in letter-writing. All this brief correspondence is the offspring of the electric telegraph. Our forefathers were not used to it, and would have regarded it as an offence. Even at the present date (1884) it is not quite safe to write in our brief modern way to persons who came to maturity before the electric telegraph was in use. There is a wide distinction between brevity and hurry; in fact, brevity, if of the intelligent kind, is the best preservative against hurry. Some men write short letters, but are very careful to observe all the forms; and they have the great advantage that the apparent importance of the formal expressions is enhanced by the shortness of the letter itself. This is the case in Robert Warcopp's letter to Sir Robert Plumpton. When hurry really exists, and it is impossible to avoid the appearance of it, as when a letter _cannot_ be brief, yet must be written at utmost speed, the proper course is to apologize for hurry at the beginning and not at the end of the letter. The reader is then propitiated at once, and excuses the slovenly penmanship and style.
