It is found to be difficult, in this country, to keep the curing-room as 

 cool as it ought to be, viz. from 54° to 58° Fahrenheit. One method 

 which is very effective in this respect is to build the bulk of the curing- 

 room underground, only sufficient of the walls being above ground to 

 allow of the insertion of narrow windows, with their length horizontal. 

 The eaves of the curing-room project well beyond these windows, to 

 increase the coolness of the room. If any trouble is expected due to 

 dampness of the walls, the side thereof next the earth should be pointed 

 deeply with 1 : 1 cement mortar, and then coated with a mixture of tar 

 and pitch. 



In a large dairy, a vertical boiler and proper hot water system is 

 usually installed. In small dairies such as those described, however, 

 the usual arrangement consists simply of an open boiler built in brick- 

 work, and situated in some convenient position outside the dairy, but 

 near at hand.
