Gr 4-7 The team of Patent and Munoz contribute another useful and unique volume on the science of horsemanship. Five chapters and 51 color photographs describe the differences among the many shades, patterns, and markings of horses' coats. Included are basics about heredity and why colors vary. In her usual no-nonsense style, Patent defines scientific and equine terms. Unfamiliar words are italicized in the text and included in a three-page glossary. Patent also notes the lack of consistency in differentiating some colors. One statement, claiming that there is no difference between the pinto and paint, will probably infuriate supporters of the American Paint Horse Association, who consider paint horses as a distinct breed in which only certain pintos may qualify. Munoz' photographs display a uniformly high standard. The subject continues to fascinate young horse lovers, and this book is bound to be a favorite.
