Work Horse Handbook by Lynn R. Miller (1983, Paperback)

Though there are many books about Draft and Work Horses, this is the one that will stand out in many people's mind.
Written by long time teamster Lynn Miller, the Work Horse Handbook has more photos than any I've seen, and if what they say is true, "a picture is worth a thousand words", then we have millions!
Very well categorized so one can find a particular subject easily, the WHH contains much insight into the draft horse on the farm, as well as handy diagrams showing such items as:
how to hook multiple hitches
how to drive multiple hitches, as well as reinsmanship
measurements for eveners, tongues, and more
The first edition was wildy popular, and this 2nd edition has expanded fully to answer nearly any question one would have about the work horse

Amateur, Novice, and Experienced teamsters can all gain knowledge from this book.
