room bulkhead. As hot air always moves upward and cold air down- 
ward, this influence would naturally be expected to affect the corn 
stowed against the upper part of the boiler-room bulkhead more than 
that which was stowed against the lower part, which proved to be the 
ease in this shipment. That part of the dried “B” corn which was 
located against the upper part of the boiler-room bulkhead increased 
in temperature at a

of the voyage than 
the corn in any other 
position in the ship. 
The temperature of 
all the corn stowed 
along this bulkhead 
registered under 65° 
F. at the time of 
loading. From early 
morning until 4 
o’clock in the after- — pwzrcne 
noon of the day of 2 
sailing, March 8, the 
ship’s boilers were 
under pressure of % 
steam, and consider- 
able heat was gen- 
erated in the boiler 
room. In this short 
time the tempera- 
ture of the corn 
located against the 
upper part of the 
bulkhead had in- 
creased to 76° F., as :

thermometer 18 in 
figure 6, while the corn at the same height in the hold, not more than 
8 feet away from the bulkhead, was only 62° F., as is shown by tem- 
perature record of thermometer 22. Hight days later the corn against 
the upper part of the boiler-room bulkhead had increased to 102° F., 
while the temperature of the corn located only 8 feet away was only 
65° F. From March 17 to 19, inclusive, the weather was stormy, and 
no more readings were made until March 20, 12 days after sailing, by 
which time the temperature of the corn along the upper part of the 
bulkhead had increased to 118° F., a total increase of over 53° F.,
