SHRINKAGE OF SHELLED CORN IN CARS IN TRANSIT. 9 
of 31.5° F. for the corn in all of the cars. At the time of unloading 
the range in Lem Eun ire was from 29° to 33°, with an average of 
30° IB or an average decrease of 1.5 degrees. The average tempera- 
ture of the corn at the time of loading it into the cars which were 
held on the track in Baltimore ranged from 30° to 35°, with an av- 
erage of 31.5° F. for the corn in all the cars. At the time of unload- 
ing the temperature ranged from 31.7° to 38.2°, with an average of 
383.9° F. This is an average increase of 2.4 degrees, as compared with

Fic. 3.—Diagram showing the loss in the weight of the corn, the average temperature of 
the corn in each of four cars in transit from Baltimore to Chicago and return, and 
also the mean daily air temperature through which the cars passed, as compared with 
the same factors on the four duplicate cars cf corn held on the track at Baltimore in 
the second experiment. 
an average decrease of 1.5 degrees for the cars moved from Baltimore 
to Chicago and return. This variation in the temperature of the 
corn was due to the wide difference in air temperature between 
Baltimore and the western points, as shown in figure 3, page 9. 
The condition of the corn in the second experiment was practically 
the same at the end as at the beginning of the test. This is shown in 
fioure 3 by the fact that the average temperature of the corn in the 
ears did not increase to any great extent from the time they were 
loaded until they were unloaded.
