有声读物: Agriculture for Beginners

A textbook used by many public schools in the early 20th century. The authors believe that "agriculture is eminently a teachable subject. They see no difference between teaching the child the fundamental principles of farming and teaching the same child the fundamental truths of arithmetic, geography, or grammar. They hold that a youth should be trained for the farm just as carefully as he is trained for any other occupation, and that it is unreasonable to expect him to succeed without training." - Summary by the authors
