Illustrated by Shafer,(MA). This book is a journey into the mind of one of America's most revered naturalists, arguably the man who launched the modern environmental movement. These journal entries were written during Leopold's field trips, and form the basis of his ideas on land ethics. They describe two long canoe trips in Canada and a trip to Mexico, where Leopold hunted deer with bow and arrow. The longer essays are taken from more contemplative notes which were still in manuscript form when Leopold died in 1948.
