This is a sensible book. I want you to understand that. This is a book to improve your mind. In this book I tell you all about Germany--at all events, all I know about Germany--and the Ober-Ammergau Passion Play. I also tell you about other things. I do not tell you all I know about all these other things, because I do not want to swamp you with knowledge. I wish to lead you gradually. When you have learnt this book, you can come again, and I will tell you some more.
