as is shown by the temperature records for thermometers 13, 14, 
and 15 in figure 21. The corn located next to the bulkhead oppo- 
site the donkey boilers showed a rapid increase in temperature at 
the time of-loading, while steam was kept up in the boilers, and 
showed a higher temperature than the corn located the same height 
but some distance back from the bulkhead until March 27, when it 
was lower. When steam was again generated in the donkey boilers

hatch was kept closed, the temperature of the corn contiguous to the 
bulkhead increased 23 degrees, as is shown by the temperature record 
for thermometer 10. The corn stowed along the bottom of hold 3 near 
the boiler-room bulkhead had a lower temperature during the greater 
part of the voyage than the corn some distance away, and this can be 
accounted for in that the temperature at the bottom of the boiler 
room was kept cool by the fresh air that rushed from the ventilators 
and took the place of the heated air that was forced out at the top.
