The children who read fairy books, or have fairy books read to them, do not read prefaces, and the parents, aunts, uncles, and cousins, who give fairy books to their daughters, nieces, and cousines, leave prefaces unread. For whom, then, are prefaces written? When an author publishes a book 'out of his own head,' he writes the preface for his own pleasure. After reading over his book in print - to make sure that all the 'u's' are not printed as 'n's,' and all the 'n's' as 'u's' in the proper names - then the author says, mildly, in his preface, what he thinks about his own book, and what he means it to prove - if he means it to prove anything - and why it is not a better book than it is.
