By reference to Table 12 it will be seen that as regards both protein 

 and energy the dietary of the Maine lumbermen on an average exceeded 

 that of the Bavarians. 



As regards the protein, the Maine lumbermen received in general 

 somewhat smaller amounts than the Russian laborers at severe work, 

 but the amounts of energy in their dietaries were larger. The amounts 

 of fat in the Russian dietaries were notably small. The foods eaten 

 by the Russian laborers differ much in character from those commonly 

 used in America, and therefore a more detailed comparison would 

 hardly be warranted, as the digestibility of the foods is a matter which 

 should always be taken into account. 



With the exception of one study with a football team the dietaries 

 of the New England men at severe work quoted in Table 12 are the 

 largest hitherto reported in connection with tlie series of nutrition 

 investigations of which the present studies are a part, though it should 

 be pointed out that these were comjjiled from statistics of food pur- 

 chased as shown by the books of the boarding-house keepers, and are 

 therefore only approximations, whereas the dietaries of the football 

 teams, bicyclists, and rowing clubs were carefully made and, like 

 those of the lumbermen here reported, show the nutrients and fuel 

 value of the food actually eaten. The dietaries of the Maine lumber- 

 men on an average exceeded the dietaries of athletes very consider- 

 ably as regards energy. In the case of protein the average amount is 

 smaller than was observed with the football teams, but greater than 

 in the case of the rowing clubs. 



As most of the men in the Maine lumbermen dietaries were French 

 Canadians, the results of some other dietary studies of men of this 

 nationality are given. The large size of these dietaries of men at 

 work in tlie Maine woods as compared with the results of other studies 

 of French Canadians is striking. 



THE COST OF THE FOOD. 



In the dietaries of the Maine lumbermen the cost of food ranged 

 from 15.1 cents per person per day in the case of the men driving logs 

 on the river to 28. G cents in the case of one of the studies made with 

 men who were chopping and yarding. On an average the total cost 

 was 2o.5 cents. The sum expended for animal food ranged from 10. G 

 cents in the case of dietary No. 392 (river driving) to IS.l cents in the 

 case of dietary No. 390 (chopping and yarding). The amount 

 expended for vegetable food ranged from 4.5 cents with dietary No. 

 392 to 10.6 cents witli dietary No. 393 (chopping and yarding). It 

 will be seen that on an average about two-thirds of the total expendi- 

 ture was for animal food and about one-third for vegetable food. Tlie 

 pi-oportion of the total cost that was expended for different articles of 

 diet in these studies is shown in the following table:
