PREFACE 



Notwithstanding the fact that the milk problem is 

 constantly growing more acute in many parts of the 

 United States, no book has thus far appeared treating, 

 in a brief space, its main aspects and stressing the 

 practical and economic as well as the sanitary factors 

 involved. The present volume is designed to fill this 

 obvious need by providing a convenient survey of a 

 perplexing subject, not merely for health officials and 

 milk inspectors, but also for dairymen and city milk 

 dealers, agricultural authorities, legislators charged with 

 the framing of milk laws, inquiring consumers and 

 members of organizations engaged in efforts to secure 

 better milk supplies, physicians, and all others who are 

 interested in the understanding and solution of the milk 

 problem.
