stance in a small tin dish. When melted slowly and 

 then allowed to boil, oleomargarine will sputter 

 briskly, but produce little or no foam. Butter, on 

 the contrary, boils with little noise and produces 

 abundant foam. 



Cheese made from whole milk is composed of all 

 the elements of the milk, except a large part of the 

 water and the sugar, which are lost in the souring 

 process. Cheese made from skimmed milk has less 

 fat, is not as nutritious, and should be much less ex- 

 pensive. A higher priced quality is made by adding 

 cream to pure milk. The more cream or fat cheese 

 contains, the softer it is, and, as a rule, the more it 

 costs. 



That cheese is a valuable food for those who can 

 digest it without difficulty, can readily be seen from 

 the fact that one pound contains even more building 

 material than a pound of beef. When eaten in place 

 of meat, as it often is in France and Italy, with bread, 

 green vegetables, and oil, it makes an inexpensive as 

 well as a very nutritious meal. Toasted cheese is 

 especially difficult to digest. Sometimes, when mixed 

 with other substances, cheese is much more readily 

 digested by some people than in the usual solid form. 

 It is well to remove the rind before eating cheese, 

 as unwholesome substances are said to be used to 

 preserve it.
