CARRYING QUALITIES OF EXPORT CORN. 33 
The temperature of the corn near the center of the bottom of the 
hold increased 19 degrees during the first two weeks, reaching its 
maximum of 89° F. April 14, after which it gradually became cooler, 
being affected by the water temperature, and dropped to 79° on 
April 8. 
TaBLE 13.—Condition of the dried corn in hold 3 as loaded and the change in condition 
while the corn was in the vessel—samples taken in order in the hold, from top to 
bottom.

As is shown in Table 13, the corn became badly damaged in the 
upper part of the hold, the degree of damage gradually decreasing 
toward the bottom. It will be seen in Table 10 that the averages 
for various factors in the analyses of the corn as discharged were as 
follows: Acidity 31.6 c. c., germination 13.2 per cent, sound kernels 
49.6 per cent, and 51.86 pounds test weight per bushel, which, com- 
pared with the average condition of the corn as loaded, was an 
increase of 9.9 c. c. in acidity and a decrease of 30 per cent in germi- 
nation; 43.9 per cent in sound kernels; and a little over 2.5 pounds 
in test weight per bushel. 
INFLUENCE OF BOILER HEAT ON THE CORN. 
There were three main boilers and two donkey boilers in the stoke- 
hold. The donkey boilers were located near the middle of the bulk- 
head which separated the stokehold from hold 3. This bulkhead 
was lined with a plank sheeting on the cargo side, but there was no 
second bulkhead to form an air space. There were coal bunkers 
over and on both sides of the stokehold, as is shown in figures 20 
and 22. Steam was kept up in the donkey boilers during the load- 
ing period, and the effect of the heat generated was plainly noticeable 
on the corn stowed contiguous to this bulkhead opposite the boilers,
