To Leon WerthI ask the indulgence of the children who may read this book for dedicating it to a grown-up. I have a serious reason: he is the best friend I have in the world. I have another reason: this grown-up understands everything, even books about children. I have a third reason: he lives in France where he is hungry and cold. He needs cheering up. If all these reasons are not enough, I will dedicate the book to the child from whom this grown-up grew. All grown-ups were once children-- although few of them remember it. And so I correct my dedication:To Leon Werth "when he was a little boy" Chapter 1we are introduced to the narrator, a pilot, and his ideas about grown-upsOnce when I was six years old I saw a magnificent picture in a book, called True Stories from Nature, about the primeval forest. It was a picture of a boa constrictor in the act of swallowing an animal. Here is a copy of the drawing.In the book it said: "Boa constrictors swallow their prey whole, without chewing it. After that they are not able to move, and they sleep through the six months that they need for digestion."
