THIRD EXPERIMENT, MARCH 2 TO MARCH 239, 181i. 4 
CORN LOADED INTO CARS. 
On March 2, 1911, four lots of corn were selected and two cars 
were loaded from sah of the four lots. This corn was selected and 
handied in the same manner as that in the second and fourth experi- 
ments, one car from each lot of corn being held on the track at Balti- 
more, while the duplicate car from each lot was forwarded to Chi- 
cago and returned to Baltimore via the Pennsylvania Railroad. The 
eight ears were equipped with electrical resistance thermometers as 
in the two preceding experiments. 
The average condition and quality of the corn in each lot at the be- 
ginning of the experiment, as represented by the results of the analy- 
ses of samples taken when the corn was being loaded after it had 
been thoroughly mixed in the eley rator, are shown in Table V.

From Table V it will be seen that the average eee content of 
the corn in lot No. 1 was 21.6 per cent; lot No. 2, 19.9 per cent; lot 
No. 3, 17.4 per cent; and lot No. 4, 14.1 per cent. The percentage 
of sound corn ranged from 94.8 per cent in lot No. 1 to 98 per cent 
in lot No. 4. 
SHRINKAGE IN THE WEIGHT OF THE CORN. 
The quantity of corn placed in each car, the shrinkage in weight 
while in the cars from March 2 to March 29, 1911, and the average 
temperature of the corn in each car at the time of loading and 
unloading are given in Table VI. These same factors, together with 
the daily mean temperature of the air through which the cars passed 
in transit from Baltimore to Chicago and return, and the daily 
average temperature of the corn in each of these cars, as compared 
with like records made in connection with the cars held on the track 
in the Pennsylvania Railroad yards, at Baitimore, are shown in 
figure 4.
