requirements, afford little information as to the selection of 
food materials under conditions such as are here presented. 
An estimate of the food purchased by a canoeing party in 
Maine has been reported in a compilation of dietary studies by 
Atwater,* but the amounts of food eaten were not ascertained 
and the work as a whole is considered unreliable. Data regard- 
ing the food consumption of subjects voluntarily walking con- 
siderable distances for several days, living entirely out of doors, 
and depending for their food supply on what could be procured 
from day to day, appear to be lacking. 
THE SUBJECTS. 
The subjects were two men, 24 years of age, engaged at 
sedentary occupations for the entire year except for the sum- 
mer vacation. One, hereafter referred to as C. H. C., was a 
college instructor, and the other, H. L. K., the author of this 
report, was an employee of the U. S. Department of Agricul- 
ture and engaged for about eight hours per day in editorial 
work pertaining to the nutrition investigations. Both ordi- 
narily took comparatively little exercise, though both played 
tennis and walked short distances as opportunity permitted. 
Neither subject had ever taken any walk of so extensive a 
nature, nor had had practical experience in camping or of liv- 
ing for more than a few meals on other than the ordinary diet. 
Previous to the trip the food consumption of both subjects had 
been noticeably small. 
THE TRIP. 
The trip began with a railroad journey of 150 miles to the 
heart of the White Mountain district and continued for seven 
days, return being made on the eighth by a similiar trip by 
rail. In the interval a stretch of about fifty miles was trav- 
ersed on foot. There were also many detours to points of in- 
terest, including several mountain climbs. 
The mileage walked was recorded by a pedometer, and 
showed a total of 157.75 miles, or 22.54 miles per day. It 
should be stated, however, that in principle the pedometer is a 
register not of distance but of the number of steps taken, and 
its accuracy in measuring distance depends upon the uniformity
