Appendix 



Butterfat differential — A premium or deduction for milk testing above or below 3.7 percent 

 butterfat, expressed as cents per hundredweight of milk for each one-tenth percent of butterfat. 



Class I milk — Fluid milk distributed to consumers. Pasteurization is the only change from the 

 natural form allowed for such milk. 



Class II milk — Fluid milk purchased from producers supplying Class I milk, but not marketed 

 in fluid form — also called surplus. 



Composite price — The average price paid by dealers for all milk purchased. It is an average 

 of the Class I and Class II prices weighted by the proportions of milk sold in the respective classes. 



Dealer — An agency purchasing milk for fluid sale from one or more producers, the major activity 

 being selling, not producing. 



Flat plan — A method of payment in which the established Class I price is paid for all milk pur- 

 chased. Such purchase may be on a straight volume basis at the price for milk containing 3.7 

 percent butterfat, or on a weight and test basis with adjustment above or below 3.7 percent accord- 

 ing to an established butterfat differential. 



Intermediate dealer — An agency purchasing milk for resale from other dealers rather than from 

 producers. 



Primary market — Because of its size, measured by the population of the consuming area, and its 

 relationship to adjoining markets, Boston is the only primary market in Massachusetts.

 dealers. 



Producer-dealer — An agency producing, as well as buying from producers, milk for fluid sale. 



Producer-distributor^.'^n agency selling at retail or wholesale delivery milk produced only on 

 his own farm. 



Rating plan — A method designed to regulate the supply evenly during the seasons of the year 

 by prorating among the producers the amount of money due to them tor milk sold. This is done 

 according to a previously assigned daily average volume, known as the base or rating. Each pro- 

 ducer is paid Class I price for milk within his rating and Class II price for that in excess of that 

 rating. 



Secondary Market — All organized milk markets in Massachusetts, with the exception of Boston. 



Surplus— Class II milk. 



Use plan — A method of payment according to the percentage division of a dealer's sales between 

 Class I and Class II milk. Such percentage division is periodically applied equally to all producers 

 of a single dealer.
