All the stories about Princes and Princesses in this book are true stories, and were written by Mrs. Lang, out of old books of history. There are some children who make life difficult by saying, first that stories about fairies are true, and that they like fairies; and next that they do not like true stories about real people, who lived long ago. I am quite ready to grant that there really are such things as fairies, because, though I never saw a fairy, any more than I have seen the little animals which lecturers call molecules and ions, still I have seen people who have seen fairiestruthful people. Now I never knew a lecturer who ventured to say that he had seen an ion or a molecule. It is well known, and written in a true book, that the godmother of Joan of Arc had seen fairies, and nobody can suppose that such a good woman would tell her godchild what was not truefor example, that the squire of the parish was in love with a fairy and used to meet her in the moonlight beneath a beautiful tree. In fact, if we did not believe in fairy stories, who would care to read them? Yet only too many children dislike to read true stories, because the people in them were real, and the things actually happened. Is not this very strange? And grown-ups are not much wiser. They would rather read a novel than Professor Mommsen's 'History of Rome'!How are we to explain this reluctance to read true stories? Is it because children are obliged, whether they like it or not, to learn lessons which, to be sure, are often dry and disagreeable, and history books are among their viii lessons. Now Nature, for some wise purpose probably, made most children very greatly dislike lesson books. When I was about eight years old I was always reading a book of true stories called 'The Tales of a Grandfather': no book could be more pleasant. It was in little dumpy volumes that one could carry in his pocket.
