Prefaces written to explain the objects and meaning of a book, or to make any appeal, ad miseracordiam or other, in its favor, are, in my opinion, nuisances. Any book worth reading will explain its own objects and meaning, and the more it is criticized and turned inside out, the better for it and its author. Of all books, too, it seems to me that novels require prefaces least-at any rate, on their first appearance. Notwithstanding which belief, I must ask readers for three minutes' patience before they make trial of this book.
