March, 1939. These prices are composite prices and are for market milk 

 of 3.7 per cent butter-fat. They have been weighted by quantities de- 

 livered (in a few instances, approximations of deliveries have been made 

 on the basis of quantities sold). 



The normal seasonal movement in Boston composite prices is much 

 greater than that in most secondary New Hampshire markets. Conse- 

 quenth, the particular period during which the comparison is made may 

 influence greatly the price relations between various markets. In this con- 

 nection, however, an index of seasonal variation in the Boston market for 

 the period 1920-38 has shown the month of Aiarch to represent 98.8 per 

 cent of the average for the year.' In this computation, A4arch showed less 

 deviation from the average of the year than any other single month. Thus 

 while prices for a particular year may vary widely from the seasonal 

 movement suggested above, it is reasonable to assume that the relationship
