"A small red notebook in which I kept a record of when I sent my finished draft of each chapter to Nadia Orapchuck, my typist in Bucks County, with a record of when she received it, typed it and sent it back. This was crucial, since I felt almost sick each time I had to send a chapter, so carefully edited and so almost irreplaceable, to Nadia. I bit my nails till she sent notice of its safe arrival. "Included with this book is a set of the postcards Nadia airmailed me. Their receipt was much appreciated, because twice my publishers have lost manuscripts of mine and once I lost the whole manuscript of a book on Hokusai and the plan for Hawaii in a plane crash. I am very nervous about manuscripts before they have been duplicated."
