This is specifically addressed to the trainer and teacher, rather than to the rider, but inevitably there is a great deal of value to the intelligent rider who cares to apply himself to basic principles involved. It overlaps, in this respect, much of the material contained in Littauer's Common Sense Horsemanship (Van Nostrand -- see P. 516- 1951), but is more specific, more exact in following the step by step process of training the horse and the rider. For any teacher, who is seeking the one book, this could well be recommended. Mrs. Self takes into consideration the varied schools of thought, and strikes for a sound medium. She demands as basic that a horse be trained to have confidence in his rider, that a rider be trained to have confidence in himself and his horse. And she stresses as the fundamental principles of riding (1) relaxing, in order to sense the horse; (2) experience, in order to interpret correctly; (3) balance. The book is liberally illustrated, with 28 photographic plates, and 162 carefully drawn diagrams, which show the hows, the rights and wrongs, etc. Not a book to recommend to beginning riders, as terminology, principles, etc. are directed to those already in the know.
