Before trucks and tractors, draft horses performed the heavy work of pulling wagons, plowing fields, and hauling logs. But the internal combustion engine did not entirely replace these animals; they are still used in many parts of the country for agricultural and other jobs. The Book of Draft Horses (The Lyons Press 2007) is a celebration of these "gentle giants," as well as a practical handbook on breeding, care, training, competition, and working horses.
