United States in 1900. It has also been discovered recently 

 that a horn-like substance called galalith can be made with 

 dried casein. The substance is smooth and is proof against 

 fire. It is used as a substitute for ivory, celluloid, marble, 

 hard rubber, and even amber. 1 In the manufacture of dried 

 casein in 19 10 the returns of 100 pounds of skim milk were 

 25 to 30 cents. 2 



THE GROWTH OF THE FACTORY SYSTEM 



The growth of the factory system in the manufacture of 

 butter may be shown by a comparative statement of changes 

 in the farm and factory products. While the factory 

 method was begun in 1861, the first mention of a butter 

 factory made in the United States Census was in 1880. 

 The increase in the factory output as well as the total 

 amount of butter produced in the United States from 1850 

 to 1 9 10 are shown in Table no. 2. 



The farm product increased steadily from 1850 to 1880
