Here is a description I found of the hardback version on Alibris:
“Detailed illustrated end-papers in black and white. Illustrated throughout with most graphic art by Farwell and some black-and-white photographs. Month-by-month chapters, September through June (school year) present nature-related activities and outdoor projects suitable for elementary school teachers and their classes. Each subject is accompanied by detailed descriptions of activities geared toward all grades, primary grades and junior/intermediate grades. Full of information.”
