In writing to French Ministers of State it is a traditional custom to employ a certain paper called "papier ministre," which is very much larger than that sent to ordinary mortals. Paper is by no means a matter of indifference. It is the material costume under which we present ourselves to persons removed from us by distance; and as a man pays a call in handsome clothes as a sign of respect to others, and also of self-respect, so he sends a piece of handsome paper to be the bearer of his salutation. Besides, a letter is in itself a gift, though a small one, and however trifling a gift may be it must never be shabby. The English understand this art of choosing good-looking letter-paper, and are remarkable for using it of a thickness rare in other nations. French love of elegance has led to charming inventions of tint and texture, particularly in delicate gray tints, and these papers are now often decorated with embossed initials of heraldic devices on a large scale, but that is carrying prettiness too far. The common American habit of writing letters on ruled paper is not to be recommended, as the ruling reminds us of copy-books and account-books, and has a mechanical appearance that greatly detracts from what ought to be the purely personal air of an autograph. Modern love of despatch has led to the invention of the post-card, which, from our present point of view, that of courtesy, deserves unhesitating condemnation. To use a post-card is as much as to say to your correspondent, "In order to save for myself a very little money and a very little time, I will expose the subject of our correspondence to the eyes of any clerk, postman, or servant, who feels the slightest curiosity about it; and I take this small piece of card, of which I am allowed to use one side only, in order to relieve myself from the obligation, and spare myself the trouble, of writing a letter." To make the convenience absolutely perfect, it is customary in England to omit the opening and concluding salutations on post-cards, so that they are the _ne plus ultra_, I will not say of positive rudeness, but of that negative rudeness which is not exactly the opposite of courtesy, but its absence. Here again, however, comes the modern principle; and promptitude and frequency of communication may be accepted as a compensation for the sacrifice of formality. It may be argued, and with reason, that when a man of our own day sends a post-card his ancestors would have been still more laconic, for they would have sent nothing at all, and that there are a thousand circumstances in which a post-card may be written when it is not possible to write a letter. A husband on his travels has a supply of such cards in a pocket-book. With these, and his pencil, he writes a line once or twice a day in train or steamboat, or at table between two dishes, or on the windy platform of a railway station, or in the street when he sees a letter-box.
