Greene explains the paradoxical thriving of the 19th-century horse with a pleasing balance of narrative analysis and colorful detail.
   --Caleb Crain, New York Times Book Review

A lively parade of horses and the people who worked with them fills this rich portrait of living things functioning as machines. By focusing on horsepower and horse culture as energy technologies, Greene tells a fresh and fascinating story.

An exceptional book that helps us understand the full dimensions of the working horse's contributions to American society.
   --Joel A. Tarr, co-author, The Horse in the City: Living Machines in the 19th Century

Horses At Work is an important contribution to the histories of both urban and rural America. Greene's deep understanding of the animals themselves adds a crucial dimension to the fascinating story she tells.
