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 dis- 

 eases are naturally brief. An effort has been made to con- 

 veniently 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 dis- 

 cussed in books of this class, the writer believes will be of value 

 for reference and instructional work. 



\Vlien 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 pre- 

 vention 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 treat- 

 ment of disease, but such treatment is suggested in the most 

 necessary cases.
