182 BOARD OF AGRICULTURE. [Pub. Doc. 



One pound of wheat flour will absorb a little over one-half 

 pint of liquid, and mixed with milk it has .02 of a pound of 

 protein and 162 calories more food value than it would have 

 mixed with water. 



Bear in mind that this is not an exhaustive treatise on 

 foods, and cannot consider such questions as the variety 

 necessary to keep up the appetite and digestion. I can do 

 hardly more than present the bald statement that in a quart 

 of milk is about one-fourth the amount and properties of 

 food for a man doing a moderate amount of muscular work. 



A moment in consideration of the products of milk, — 

 butter and cheese. This table tells the story and compares 

 milk and its products with the standard : — 



Man doing ordinary work needs, 

 Four quarts of milk contain. 

 One pomid full cream cheese, 

 One pound skim-milk, 

 One pound butter, 



The butter, which is the fat of milk, has practically no pro- 

 tein and is very rich in the fuel elements. It is of great 

 food value in balancing rations deficient in fat ; and for that 

 condition of invalidism calling for more fat, butter or cream 

 are for many people better than cod-liver oil or patent 

 nostrimis. 



Cheese, which retains the casein of the milk as well as the 

 fat, has in one pound almost enough protein for a day's 

 rations, but is deficient in the fuel functions. These, how- 

 ever, can be easily supplied in other ways. A pound of 

 cheese has more nutriment than a pound of beefsteak, and 

 cheese should be more used as food. 



A half pound of cheese and two pounds of corn meal is —
