CARRYING QUALITIES OF EXPORT CORN. 73 
the corn at the bottom fluctuated somewhat, being influenced to 
some extent by the temperature of the sea water. 
Hold 3 was filled with corn to the second deck. The corn as dis- 
charged was badly heat damaged in the upper part of the hold and 
ranged from 65° to 141° F. in temperature, 27.6 to 47.7 c. c. in acid- 
ity, 0 to 65 per cent in germination, 0 to 91.8 per cent in sound 
kernels, and 47 to 53.8 in test weight per bushel. The corn in this 
hold at time of load- 
ing had a tempera- 
ture ranging from 56° 
to 66° F., which tem- x !20

There was not much 
change in the temperature of the corn located one-third of the dis- 
tance down in the hold in the first 10 or 12 days of the voyage, but 
from that time on it increased more rapidly until on April 24 it was 
118° F., asis shown by the record for thermometer 10. The corn sur- 
rounding this thermometer, as discharged, tested 34 c. c. in acidity 
and 34 per cent in germination. The temperature of the corn located 
two-thirds of the distance down in the hold increased only 9° F. 
during the time it was in the vessel, as is shown by the tempera-
