I am 71 years old. This book was first published in 1958. It was my favorite book as a child and I remember it well. I don't have my copy any longer, but maybe I'll buy a new one! I loved being out in my back yard as a child and I still do. I credit this book with my love of all things in nature. Diane Kramer Chappell Hill, TX
