PREFACE 



This book was written for use in High Schools, Schools of 

 Agriculture, Colleges of Agriculture, general courses. Rural 

 Consolidated Schools and for the many studious young farmers 

 who have been deprived of systematic agricultural education. 



From an experience of more than thirty years in dairy work, 

 covering much of the United States, the author has written, 

 Avithout haste, what he feels and knows, from innumerable ques- 

 tions asked, to be what the thoughtful reader desires to know. 

 Many of the finer and more technical points have been omitted. 

 There is enough that is known to furnish a foundation and guide 

 for good practice. 



The lists of questions foUovidng every chapter will aid the 

 student in fixing in his mind the essentials of the points 

 discussed. 



The chapter on common diseases was written by Dr. W. L. 

 Boyd, Assistant Professor of Veterinary Medicine, University 

 of Minnesota, for this book.
