at the bottom of the hold but located 30 feet distant from this bulk- 
head. This was a higher increase in temperature by 100°, 77°, and 
10° F., for the corn located against the upper, middle, and bottom 
parts of the boiler-room bulkhead, respectively, than the increase in 
temperature for the corn located at a corresponding depth in the hold 
but from 15 to 30 feet distant from this bulkhead, and clearly shows 
the effects of the boiler heat on corn having a high moisture con- 
tent when stowed in 
this position in the 
vessel.

charged in good con- 
dition. As is seen in figure 59, the damaged corn next to the engine- 
room bulkhead had the highest temperature at the upper part 
of the bulkhead and the temperature decreased toward the bot- 
tom of the hold, also toward the center of the hold. Thermometers 
29, 37, and 41, located next to the engine-room bulkhead near the 
surface, halfway down, and near the bottom of the hold, indicated 
a rapid increase in temperature from the first day that the corn was
