_Salting and Pressing._--Salt is added for several purposes, chiefly for flavoring, but it also has other uses. It aids in removing the whey,--it hardens the curd and it checks or retards the formation of lactic acid. Excessive salting, however, is injurious. From 2¹⁄₂ to 3 pounds of salt should be added to the curd made from 1000 pounds of milk. Before putting in the press the curd is cooled to a temperature of about 80 degrees, and after putting into the mold it is subjected to pressure to give it a proper form, rather than to remove the whey which is practically all gone by this time. If the whey has not been properly removed before the cheese goes into the press it is almost impossible to get it out then. The pressure should be uniform and continued for at least twenty-four hours. If a screw is used the pressure should be light at first and gradually increased. After the cheese has been in the press about an hour it is removed, turned, a cloth adjusted about it, and the entire surface wiped carefully with a cloth wrung out of hot water. The sizes in which American cheeses are made depends largely upon the market, the more common size being 15 inches in diameter, and the cheese weighs from 60 to 65 pounds. There is also a very large manufacture of cheese seven inches in diameter, known as “Young Americas” and weighing only from 8 to 10 pounds. _Curing._--The higher the temperature to which cheese is exposed in curing the more rapid the curing process will take place, but the poorer the quality of the cheese. Experience has shown that a low temperature, 55 degrees F. or even less, gives much better results, although it requires a greater length of time. If cured at a higher temperature the fat is apt to exude, and will not be evenly distributed in the cheese. It is, therefore, more profitable, as well as better for the consumer, to cure at low temperatures, producing a superior quality with less loss of moisture and a cheese which sells for a better price. _Moisture in the Curing Cellar._--The cellar in which the curing takes place should contain air with a proper degree of moisture. The relative percentage of moisture in the air as compared with the total amount which it can hold should be from 65 to 75. This is determined by placing in the curing room a hygrometer which registers the degree of saturation.
