AUTHOR'S PREFACE 



MILK is a food in the distribution of which the public 

 has taken particular interest, and on which much hasl>een 

 said and written. Numerous investigations have been 

 made and reports issued upon the subject. The author 

 has made a careful study of all such material available, in 

 order to supplement information gained from a number of 

 years of personal contact with the milk business in various 

 parts of the country, and has attempted here to present a 

 rounded out discussion of some of the economic phases of 

 milk distribution and of the ever present problem of price 

 determination. It is hoped that such a presentation may 

 aid in clearing the air of much that is beside the point or 

 even in error and may give a clearer conception of the 

 whole problem to those who are calle^l upon to solve it. 



Acknowledgment should be made for the assistance 

 rendered by a large number of milk dealers, by officers of 

 milk producers' associations, by public officials, and by 

 some of my fellow teachers. Special acknowledgment is 

 due to Professor B. H. Hibbard, of the University of 

 Wisconsin, and to Professor J. I. Falconer, of Ohio State 

 University, who very carefully read the manuscript and 

 gave helpful suggestions.
