Phillip Keller (1920-1997), author of this one-hundred thirty-one-page compact book, gained widespread accolades for his authorship of this book. Being born in East Africa, the son of missionaries, Keller became familiar with the open air, nature, and shepherding. Subsequently, Keller traveled the world as a nature photographer and an expert in the science of soil management and crop production.
These life experiences prepared Keller to author this book and his other thirty-five Christian books.
