Once 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." I pondered deeply,
then, over the adventures of the jungle. And after some work with a colored
pencil I succeeded in making my first drawing.
