A pleasant letter I hold to be the pleasantest thing that this world has to give. It should be good-humoured; witty it may be, but with a gentle diluted wit. Concocted brilliancy will spoil it altogether. Not long, so that it be tedious in the reading; nor brief, so that the delight suffice not to make itself felt. It should be written specially for the reader, and should apply altogether to him, and not altogether to any other. It should never flatter. Flattery is always odious. But underneath the visible stream of pungent water there may be the slightest under-current of eulogy, so that it be not seen, but only understood. Censure it may contain freely, but censure which in arraigning the conduct implies no doubt as to the intellect. It should be legibly written, so that it may be read with comfort; but no more than that. Caligraphy betokens caution, and if it be not light in hand it is nothing. That it be fairly grammatical and not ill spelt the writer owes to his schoolmaster; but this should come of habit, not of care. Then let its page be soiled by no business; one touch of utility will destroy it all.
If you ask for examples, let it be as unlike Walpole as may be. If you can so write it that Lord Byron might have written it, you will not be very far from high excellence.
But, above all things, see that it be good-humoured.
Bertram's letter to the lady that he loved was by no means one of this sort. In the first place, it was not good-humoured; it was very far from being so. Had it been so, it would utterly have belied his feelings. Harcourt had so written to him as to make him quite clearly understand that all his sins and--which was much more to him--all his loves had been fully discussed between his friend and Miss Waddington--between his Caroline and another man. To the pride of his heart nothing could be more revolting. It was as though his dearest possession had been ransacked in his absence, and rifled and squandered by the very guardian to whom he had left the key. There had been sore misgivings, sore differences between him and Caroline; but, nevertheless, she had had all his heart. Now, in his absence, she had selected his worldly friend Harcourt, and discussed that possession and its flaws with him! There was that in all this of which he could not write with good-humour. Nevertheless, had he kept his letter to the second morning, it may probably be said that he would have hesitated to send it.
