It may be laid down as a general rule that the binding of a book should have a distinct reference to the nature of its contents. It should be appropriate to the author and to the subject. One sympathizes with Posthumus in the play, when, apostrophizing the volume in his prison, he says: 'O rare one! Be not, as is our fangled world, a garment Nobler than that it covers: let thy effects So follow, to be most unlike our courtiers, As good as promise.' Juliet, when she hears that Romeo has slain Tybalt, asks: 'Was ever book containing such vile matter So fairly bound?' And in a like spirit Charles Lamb, in his well-known essay, complains of the 'things in books' clothing' which, by reason of their inappropriate exteriors, afford so much disappointment to the reader. 'To reach down a well-bound semblance of a volume, and hope it is some kind-hearted play-book, then, opening what "seem its leaves," to come bolt upon a withering population essay'--'to expect a Steele or a Farquhar, and find--Adam Smith'--those, indeed, are doleful and dispiriting experiences, to which the unsuspecting student ought not in enlightened times to be subjected. If Mr. Gilbert's Mikado be right in the view that the punishment ought to 'fit the crime,' so assuredly ought a book's binding to fit the matter that is contained within it. It should be the outward sign of the inward grace. I am ready to admit that, as a rule, this is so. In general, it is quite easy to tell the nature of a volume from its cover. And for this the publishers are greatly to be thanked. An amateur, publishing for himself, may every now and then insist upon dressing up the product of his brains incongruously; but, for the most part, the booksellers of to-day have a very excellent sense of what is fitting. The result is that those who care about books can differentiate them at a glance. They know what is the approved style and line for biography and history, for poetry and fiction, for sermons, for gift-books, and so _ad infinitum_. The 'Life' of So-and-so, and the 'Annals' of Such-and-such, are unmistakeable; they have respectability written on every corner and angle of them. The dull brown or the dull green is sufficiently obvious to everyone. And so with poetry. You know minor verse directly you see it. It has a _cachet_ concerning which there can be no possible error. Happily, a Tennyson, a Browning, or a Swinburne is equally recognisable. A novel, of course, bears its character on its face. The three-volume form is notorious. But it scarcely matters what shape fiction may take. It can be identified by instinct, whether it be in yellow boards or in some more quiet habit. Sermons cannot be misapprehended; there is no fear of their being taken on a railway journey instead of the latest book of memoirs. As for gift-books, whether for boy or girl, adult or juvenile, they have their destination marked upon them in all the colours of the rainbow.
