“Forests and Men comprise about two-thirds of the yearbook…It is subdivided into several sections…ecology; seeding and planting; genetics; management and care of private and public forests; protection from insects, diseases, parasites and fire; wildlife; water relations; wood utilization; history; economics and policy”.
…Through its [the book’s] pages there is a strong undercurrent of sound conservation of natural resources, a guide to action that we must follow if we are to give future generations a chance to attain a reasonably adequate standard of living. This book is highly recommended”.
