SHRINKAGE OF SHELLED CORN IN CARS IN TRANSIT. L3 
109.7°, while that of the corn in transit had increased to 112° F. The 
high temperature accompanying the deterioration accounts for the 
very large natural shrinkage occurring in these cars. 
The corn in the other six cars remained at practically the same 
temperature throughout the experiment, showing only a slight in- 
erease from the time of loading until the time of unloading. This 
sheht increase in temperature was probably due to the fact that the 
atmosphere was generally warmer during the latter part of the ex- 
periment rather than to any increase in temperature resulting from 
fermentation, as the corn was in good condition when unloaded. 
FOURTH EXPERIMENT, MAY il TO JUNE 1-3, 1911. 
CORN LOADED INTO CARS. 
On May 11, 1911, eight cars were loaded with corn, two cars each 
from four special lots which had been selected according to moisture 
content. Prior to loading into the cars, each lot was thoroughly 
mixed in the elevator. One car of corn from each lot was held on the 
track at Baltimore, while the duplicate car of each lot was forwarded 
to Chicago and returned to Baltimore via the Pennsylvania Railroad. 
The cars were equipped with electrical resistance thermometers, 
which were located in the grain in the same manner as in the three 
former experiments. 
The average condition and quality of the corn in each lot at the 
beginning ef the experiment, as represented by the results of the 
analyses of samples taken when the corn was being loaded, are shown 
in Table VII.

It will be seen by referring to Table VII that the average moisture 
content of the corn in lot No. 1 was 18.2 per cent. The corn in this 
lot was considerably lower in moisture than the corn in lot No. 1 
of the second and third experiments. This was made necessary be- 
cause it was almost impossible te obtain corn having a moisture con- 
tent of more than 18 or 19 per cent that was sound and sweet at that
