A Postscript is a very useful invention: but it is not meant (as so many ladies suppose) to contain the real gist of the letter: it serves rather to throw into the shade any little matter we do not wish to make a fuss about. For example, your friend had promised to execute a commission for you in town, but forgot it, thereby putting you to great inconvenience: and he now writes to apologize for his negligence. It would be cruel, and needlessly crushing, to make it the main subject of your reply. How much more gracefully it comes in thus! “P.S. Don’t distress yourself any more about having omitted that little matter in town. I won’t deny that it did put my plans out a little, at the time: but it’s all right now. I often forget things, myself: and ‘those who live in glass-houses, mustn’t throw stones’, you know!”
When you take your letters to the Post, carry them in your hand. If you put them in your pocket you will take a long country-walk (I speak from experience), passing the Post-Office twice, going and returning, and, when you get home, will find them still in your pocket.
§ 5. On registering Correspondence.
Let me recommend you to keep a record of Letters Received and Sent. I have kept one for many years, and have found it of the greatest possible service, in many ways: it secures my answering Letters, however long they have to wait; it enables me to refer, for my own guidance, to the details of previous correspondence, though the actual Letters may have been destroyed long ago; and, most valuable feature of all, if any difficulty arises, years afterwards, in connection with a half-forgotten correspondence, it enables me to say, with confidence, “I did not tell you that he was ‘an invaluable servant in every way’, and that you couldn’t ‘trust him too much’. I have a précis of my letter. What I said was ‘he is a valuable servant in many ways, but don’t trust him too much’. So, if he’s cheated you, you really must not hold me responsible for it!”
I will now give you a few simple Rules for making, and keeping, a Letter-Register.
Get a blank book, containing (say) 200 leaves, about 4 inches wide and 7 high. It should be well fastened into its cover, as it will have to be opened and shut hundreds of times. Have a line ruled, in red ink, down each margin of every page, an inch off the edge (the margin should be wide enough to contain a number of 5 digits, easily: I manage with a ¾ inch margin: but, unless you write very small you will find an inch more comfortable).
Write a précis of each Letter, received or sent, in chronological order. Let the entry of a ‘received’ Letter reach from the left-hand edge to the right-hand marginal line; and the entry of a ‘sent’ Letter from the left-hand marginal line to the right-hand edge. Thus the two kinds will be quite distinct, and you can easily hunt through the ‘received’ Letters by themselves, without being bothered with the ‘sent’ Letters; and vice versâ.
Use the right-hand pages only: and, when you come to the end of the book, turn it upside-down, and begin at the other end, still using right-hand pages. You will find this much more comfortable than using left-hand pages.
