No book can teach you to ride, but reading may help you understand what you're doing and why. Some of the standbys are Horsemanship for Beginners by Jean Slaughter ($3.75, Knopf), Common Sense Horsemanship by Capt. Vladimir S. Littauer ($7.50, Van Nostrand), Riding and Schooling Horses by Brig. Gen. Harry D. Chamberlin ($5.00, Van Nostrand) and Teaching the Young to Ride by Margaret Cabell Self ($3.00, Barnes). Just remember to use good judgment when you ride. Don't overrate your ability, avoid recklessness and you'll find that riding can be one of your most rewarding pleasures.
