As Elly May Clampett on the long - running hit television show, ''The Beverly Hillbillies,'' Donna Douglas was noted for her love of ''critters.'' Her portrayal was true to life, because she was raised on a Louisiana farm, where she developed a love for both domestic and wild animals. In the Mulberry Acres Farm series, she presents delightful stories that express enduring lessons to be gained from the animal kingdom. In this volume, an old horse, long past its prime, shows how anyone can accomplish great things with the proper motivation.
