Preface 



The transportation of milk in tank trucks from farm to plant has 

 become important only in the 1950's. In many areas it has de- 

 veloped rapidly. It usually brings about other important changes, 

 both welcome and unwelcome. The United States Department of 

 Agriculture recognized the need of economic analysis of this sig- 

 nificant new development. 



The Department has a broad program of research in agricultural 

 marketing, designed to improve the efficiency of the marketing 

 process. The research resulting in this report was a part of that 

 program. The work was done by the University of New Hampshire 

 under contract with the United States Department of Agriculture. 

 The Agricultural Marketing Service administered the contract for 

 the Department, with Clem C. Linnenberg, Jr., of the Marketing 

 Research Division, supervising the contract on the Department's 

 behalf.
