concentrated product. Hence we find sweetened con- 

 densed milk usually concentrated in the proportion of two 

 and three-fourths to one. 



The composition of this product varies between wide 

 limits, but a fair example of a good quality of sweetened 

 condensed milk is, according to Leach, as follows: 



Relatively Large Investment Needed. The establish- 

 ment and operation of a milk condensery is a much larger 

 proposition than the manufacture of butter or cheese. 

 More milk is also necessary within a given radius. A 

 condensing plant is usually not very prosperous unless 

 there is a milk supply of 50,000 pounds per day. An ex- 

 pensive building and expensive machinery are required. 

 A good supply of cold water is a requisite. Roughly speak- 

 ing, a supply of ten times as much water as there is milk 

 to be condensed should be assured. The steam required 

 is also a large item. For each 1000 pounds of milk to be 

 condensed per day, about six horse power of steam is 

 needed. However, the profits are proportionately great, 

 and a properly conducted factory with an ample supply 

 of milk usually prospers. 



The large condensery finds it economical to use all 

 possible labor-saving devices. Cases are nailed with a 

 nailing machine and the labeling is done automatically. 

 Cans are fed in at one end of the labeling machines, are 

 carried along, a label is pasted on, and the cans are delivered 

 at the other end directly into the shipping cases without 

 further handling.
