Many, many years ago, James McCullough (sp?), then editor of Bicycling magazine,

society.

The author noted that when slavery was legal (as it was in most human societies
at one time or another) slave labor was preferred over animal labor for power
production. His explanation was that humans are more efficient than draft
animals, in terms of work out vs. food energy consumed.
