The object of this book is to arrange in the most convenient, clear, and concise form the modern system of horse-training, in so far as it is applicable to the training of horses in the mounted service of the United States. No attempt has been made in any case to improve upon methods already deemed correct by the best horsemen; and as such methods can be found dealing with all points of training, it follows that the subject matter in this book is not original. Where the best was to be found, there it has been sought, and where the authors of previous works have expressed their ideas in language considered the most concise and clear, their words have been copied verbatim, with due acknowledgement to the authors.
