SHRINKAGE OF SHELLED CORN IN CARS IN TRANSIT. 15 
Taste VIII. Weight of corn in each car immediately after leading on May 11, 
1911, and the shrinkage, or loss in weight, together with the moisture content 
at time of loading and the average temperature of corn at time of loading 
and unloading.

From Table VIII and figure 5 it will be seen that the shrinkage in 
weight was much greater in the cars of corn that were held on the 
track at Baltimore than in those in transit. The mean daily air tem- 
perature through which the cars passed while en route, as shown in 
figure 5, was considerably less than the mean daily air temperature 
that surrounded the cars at Baltimore. This caused the temperature 
of the corn in the cars on the track at Baltimore to increase faster 
than that of the corn in transit, in that the higher air temperature 
not only warmed the corn, but aiso offered much more favorable con- 
ditions for the development of molds and bacteria and for the action 
of enzyms or other unorganized ferments; consequently, the natural 
shrinkage in the weight of the corn held at Baltimore was greater 
than that of the corn in transit. 
The shrinkage in weight of the car of corn in transit representing 
lot No. 1, containing 18.2 per cent of moisture, was 1.23 per cent, 
while the duplicate car that remained on the track at pee lost 
1.6 per cent. The heavy losses Ccounrang in these two cars were di- 
rectly due to the deterioration of the corn. As may be seen me figure 
5. on May 20 the average temperature of the corn from lot No. 1 
was (9.5° in the car hele on the track at Baltimore and 75.3° in the 
car in transit. From May 20 until June 1 the temperature of the 
corn increased rapidly, and on the latter date the car of corn held at 
Baltimore showed a temperature of 129°, while the corn that had 
been shipped from Baltimore to Chicago and return showed an aver- 
age temperature of 121.2°. The corn in these two cars was in a 
very badly damaged manner when unloaded, on June 1.
