134 MAINE AGRICULTURAL EXPERIMENT STATION. 



Dietaries 4 and 5 stand in strong contrast to dietaries 1, 2, and 

 3, as in the former the waste did not exceed 14.5 per cent. This 

 is a striking illustration of the possible difference which may 

 exist in the economy of management of the food supply of a 

 family or boarding house. 



The large waste of nutrients in the spring term is emphasized 

 by the fact that the loss of fats was in greater proportion than 

 that of other nutrients, thus involving a larger relative waste of 

 food energy than is indicated by the percentages of organic 

 matter. When the waste of organic matter was 17.2, 24, and 27 

 per cent, the corresponding waste of fuel value was 20, 26, and 

 32 per cent. 



While the waste in the fall term is not as low as it might be 

 under more favorable circumstances, it was not greater than 

 frequently exists under boarding-house conditions, where there 

 is not a concerted action on the part of the boarders toward 

 economizing in all reasonable ways. 



THE FOOD ACTUALLY EATEX. 



In considering the results of these dietary studies, so far as it 

 relates to food consumption the following facts pertaining to the 

 conditions should be taken into account: 



In the spring term the period of observation began during 

 the cold weather of February and ended during the warm 

 weather of June, and included a period during which there is 

 usually a marked decrease of appetite. 



In the fall term the conditions were reversed, and there was a 

 gradual change to cold weather, which, other things being equal 

 increases the appetite. 



The supply of animal foods, and to some extent of vegetable 

 foods, was purposely changed in passing from one period to 

 another. 



The nutrients consumed in these dietary studies are briefly 

 summarized in the following: table:
