° In the 3 1/2 months before the experiment began the pig attained a weight of 42 pounds, of which 20 per 
cent was fat. The total fat in the body was 8.40 pounds. 
b In the 3 1/2 months before the experiment began the pig attained a weight of 47 pounds, of which 20 per 
cent was fat. The total fat in the body was 9.40 pounds. 
c In the 4 1/2 months before the experiment began the pig attained a weight of 54 pounds, of which 20 per 
cent was fat. The total fat in the body was 10.80 pounds. 
RELATION BETWEEN TOTAL THERMS CONSUMED AND TOTAL TllERMS 
STORED 
The pig fed com and ash consumed 19.31 therms for one stored during 
the first 400 days of the experiment. During the last 500 days of the 
experiment he consumed 3.28 therms for one stored. The pig fed corn 
and protein-free skim milk consumed 18.33 therms for one stored during 
400 days of the experiment and 3.11 for one stored during the last 500 
days of the experiment. For the pig fed corn alone the therms consumed 
were 8.23 for the first 600 days and 2.93 for the last 400 days for each 
therm stored. (Table XXV.) 
In section III it was shown that pigs fed corn alone stored on the aver¬ 
age 1 therm for 4 consumed. This was with pigs which made some growth 
on com alone. In pigs that made a small growth or none at all, the ratio
