INFLUENCE OF ENGINE HEAT ON THE CORN. 
It will be seen by the temperature records in figure 24 that the 
temperature of the corn located next to the bulkhead separating hold 
4 from the engine room was influenced to a considerable extent by 
the temperature in the engine room, expecially during the early part 
of the voyage. 
There was an unventilated water-tank space next to the engine 
room bulkhead in the upper part of the hold, which was separated 
from the cargo space by a board bulkhead that was not air-tight. 
Thermometer 23, which was located next to the tank-space bulkhead 
in the upper part of the corn, indicated an increase from 60° to 90° F., 
or an increase of 30 degrees the first 8 days ending March 10, during 
which time the corn stowed the same height but about 20 feet back 
from the bulkhead increased only 3 degrees and did not reach 96° F. 
until about March 21, 11 days later. 
TABLE 15.—Condition of the natural corn in hold 4 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. 
[T 21, etc., represents samples in crossed-wire containers, fastened to resistance thermometers of the same 
numbers; * indicates not included in the average. |

During tlte first part of the voyage, to March 23, thermometer 25, 
located against the lower part of the tank-space bulkhead about 10 
feet from the surface, also indicated a higher temperature than ther- 
mometer 26, located the same height but some distance back in the
