Craig, [Illustration: Frontispiece--INSANITARY DAIRY STABLE AND YARDS. disease AND FINANCIAL LOSS ARE TO BE EXPECTED WHEN farm Animals ARE KEPT IN FILTHY, INSANITARY QUARTERS] PREFACE In preparing the material for this book, the author has endeavored to arrange and discuss the subject matter in a way to be of the greatest service and help to the agricultural student and stockman, and place at their disposal a text and reference book. The general discussions at the beginning of the different sections and chapters, and the discussions of the different Diseases are naturally brief.

2 An effort has been made to conveniently arrange the topics for both practical and class-room work. The chapters have been grouped under the necessary heads, with review questions at the end of each chapter, and the book divided into seven parts. The chapters on Diseases of the locomotory organs, the teeth, surgical Diseases and castration, although not commonly discussed in books of this class, the writer believes will be of value for reference and instructional work. When used as a text-book, it will be well for the instructor to supplement the text with class-room discussions. The writer has given special emphasis to the cause and prevention of disease , and not so much to the medicinal treatment. Stockmen are not expected to practise the medicinal treatment, but rather the preventive treatment of disease . For this reason it is not deemed advisable to give a large number of formulas for the preparation of medicinal mixtures to be used for the treatment of disease , but such treatment is suggested in the most necessary cases.

The morbid processes that result in either slight or marked modifications of the normal condition are recognized by the injurious changes in the structure or function of the organ, or group of body organs involved. The increase in the secretion of urine noticeable in horses in the late fall and winter is caused by the cool weather and the decrease in the perspiration. If, however, the increase in the quantity of urine secreted occurs independently of any normal cause and is accompanied by an unthrifty and weakened condition of the animal , it would then characterize disease . Tissues may undergo changes in order to adapt themselves to different environments, or as a means of protecting themselves against injuries.
