SHRINKAGE OF SHELLED CORN IN CARS IN TRANSIT. 7 
weighings and temperature readings were made on the ears in transit. 
These eight cars were each equipped with six electrical resistance 
thermometers, the relative position of which is shown in figure 1. 
The average condition and quality of the four lots of corn at the 
beginning of the experiment, as represented by the results of the 
analyses of samples taken when the corn was being loaded into cars, 
are shown in Table III.

Tt will be seen by reference to Table II] that the average moisture 
content of the corn in lot No. 1 was 22 per cent; lot No. 2, 19 per 
cent; lot No. 3, 17 per cent; and lot No. 4, 13.3 per cent—a range of 
8.f per cent. Special attention is also called to the lé6w weight per 
bushel of the corn from lot No. 1, containing 22 per cent of moisture, 
and the high percentage of the badly broken corn in lot No. 4. Much 
of this broken corn was of the consistency of coarse flour or meal. 
SHRINKAGE IN THE WEIGHT OF THE CORN. 
The quantity of corn placed in each car, the shrinkage in weight 
while in the cars from December 24, 1910, to January 20, 1911, to- 
gether with the average temperature of the corn in each car at the time 
of loading and unloading, are shown in Table TV. These same data 
are presented diagrammatically in figure3. In addition to the natural 
shrinkage in weight and the other data given in Table IV, figure 3 
also shows the mean daily temperature of the air through which the 
ears passed while en route from Baltimore to Chicago and return, 
tegether with the average temperature of the corn in each car, as 
compared with like observations made on the corresponding lots of 
corn held on the track in the railroad yards at Baltimore.
