FROM CHURN TO PACKAGE 155 



prints dry after placing them in boxes, or sprinkling them 

 with water produce about the same effect on the degree 

 of shrinkage. 



" In the average small store refrigerator, the loss will 

 approximate the limit set by law in a space of ten days 

 when the prints are piled loosely on shelves." 



The law referred to by Pickerill and Guthrie is the 

 New York 1 regulation, which is similar to the rules 

 of many other states, and reads as follows : " The maxi- 

 mum variation allowed on a pound print to be three- 

 eighths of an ounce on an individual print, provided that 

 the average error of twelve prints, taken at random, shall 

 not be over one-fourth of an ounce per pound." A 

 study of the above summary makes clear that the New 

 York regulation on variation in weight of print butter 

 is fair. 



119. Printing. Butter is printed in many sizes and 

 shapes, as noted in Chapter XII. At present the most 

 popular print is somewhat the shape of a brick and 

 weighs one pound. 



History. Butter was first printed in the region of 

 Philadelphia, Pennsylvania. Until about 1900 2 this 

 was practically the only print butter market in the United 

 States. A. H. Reid, 3 Philadelphia, was the inventor of 

 the Lafayette Printer, which was one of the first machines 

 on the market. He placed the printer on sale about 1892. 

 It molded a single print at one time, and was operated by 

 a lever. Later several block printers, as seen in Fig. 50,
