These old fashioned nature readers are written from a child's view with wonder and delight in nature and the animal kingdom. Scientific observations of nature are brought to life in story form, making them fun to read and learn from. Each chapter ends with questions to help the child explain what he has learned. This classic reader is updated from texts of 19th century school books and is still fascinating and accurate. It was in these books that we discovered that the dreaded tomato hornworm comes from the eggs of the large and beautiful hummingbird moth that we frequently see at dusk flitting around our flower beds! My children have quite enjoyed these books. Grades 1 to 5. Black and white drawings, Paperback, 163 pages.
