(Fig. 20). Ice water is run through the ice section alone and is. 

 obtained from an overhead barrel holding broken ice, over which 

 water is sprayed from a large-surface nozzle, and flows from the: 

 barrel through a short hose through the ice water section. 



A similar result may be secured by using a tubular cooler 

 (Fig. 17), arranged so the general water supply may be run through 

 the upper half of the cooler, and the ice water or cold brine through 

 the lower half. By either of these contrivances milk may be; 

 reduced to a temperature below 40 .

In place of the spray-head for sprinkling water on cracked ice-

 half-inch pipe. The water supply is connected with the bottom of 

 the coil, and the top of the coil is connected with the ice water 

 section of the Star cooler. Large pieces of cracked ice are used to 

 fill the cask to the top, to which may be added rock salt and then 

 water. If salt is used, care must be taken to have the water run-
