162 STORRS AGRICULTURAL EXPERIMENT STATION. 
Less complete data are at hand in the case of C. H. C., but 
from what is known of the heat elimination of other subjects 
of his weight, here also there must have been a considerable 
deficit. 
While no definite information can be obtained as to the food 
consumption of either subject previous to the experiment, it is 
certain that their normal diet with only sedentary work was 
quite as large as when walking twenty miles aday. ‘Thisseems 
rather surprising. Zasietsky,* however, in his experiments 
with the Russian students summarized in Table 24 above, ob- 
tained similar results. In his experiments seven students after 
two or three days of absolute rest (lying down) walked for 
several days from 9 A. M. to g P. M. with short intervals of 
rest. No marked influence of exercise upon the amount of 
food consumed was noted, though he attempts no explanation 
for this. In the present investigation it seems most probable 
that the necessity of economizing in bulk and weight of the 
food carried produced a tendency to economize unconsciously 
in the food consumed. 
On the return from the journey both subjects resumed their 
ordinary diets and their usual daily occupations. Both im- 
mediately noted unusually good appetites and while the food 
was not weighed the consumption unquestionably increased. 
H. L. K. regained his initial weight in five days and C. H. C. 
in four days. At the end of a week the latter reported further 
slight gains. Aside from occasional discomfort due to climatic 
conditions, no ill effects other than loss in weight were noticed 
at any time during the journey. Both subjects felt better 
when they returned than when they started, and their subse- 
quent physical condition has revealed no detrimental results 
traceable to the trip. 
SUMMARY. 
In these studies, two young men of sedentary habit walked 
without previous training an average distance of twenty miles 
per day for seven consecutive days, each carrying about twenty- 
five pounds of luggage. Notwithstanding the unwonted phys- 
ical exertion, their food consumption did not increase, though
