520			_a"The book is for the non-agricultural engineer who wants to learn about the wide diversity of power and machines used by farmers to produce our staple food and fiber crops. It provides the reader with information needed to weigh the advantages and disadvantages of specific types of machines. Dibble Sticks, Donkeys, and Diesels will be a valuable resource for development workers, economists, extension officers, administrators, students, and agriculturalists throughout the developed and developing world."
