There has been considerable variation in the size of the cubes used, 

 some holding 63 pounds, some 68, and others approximately 80 

 pounds. As a step toward standardizing the size of the cube, the 

 San Francisco Wholesale Dairy Produce Exchange recently ruled 

 that butter offered on the exchange as " extras " should be packed 

 in cubes with sides, tops, and bottoms one-half inch in thickness 



Fig. 1. — The cube is used on the Pacific coast for solid packed bulk butter. Its inside 

 dimensions are 12J inches by 12£ inches by 13J inches. Its net weight is approxi- 

 mately 68 pounds. 



and ends seven-eighths of an inch in thickness, lumber to be sur- 

 faced on both sides, corners to be rounded, inside measurement 

 12J- by 12£ by 13£ inches, and net weight to be marked on each end. 

 The net weight of such a cube would be approximately 68 pounds. 

 Cubes of a uniform size, which are neat and attractive in appearance, 

 would be much more satisfactory and highly desirable both for local 

 and foreign markets.
