有声读物: Plow Stories

This book tells of the important role of the plow, starting from its humble beginnings and how the plow has changed over time. This is achieved through a series of small stories set during different time periods in history. The introduction of the book encourages us to, "learn all you can about plows, even if you live in a great city. City people would soon starve if there were no plows and plowmen at work to raise food for them. Not even the strongest locomotives or the most wonderful printing-presses are so necessary to us as plows. Learn all you can about them!" - Summary by SweetHome
