degrees from the previous day, and the temperature of the corn against 
the unprotected part of the boiler-room bulkhead at the extreme side 
of the hold (thermometer 25) was reduced from 95° F. on April 1 to 
82° F. on April 2, a decrease of 13° F. During the voyage the tem-

perature began. The 
corn which was stowed next to the upper part of the boiler-room 
bulkhead (thermometer 18) showed a rapid increase from the begin- 
ning of the voyage; next the temperature of the corn in the top 
layer, immediately under the after ventilator, began to increase 
rapidly about March 16. At this time in the voyage the ship en- 
countered cold air and the vapor escaping from the heating corn began 
to condense in the ventilator and fall back on the corn as water. The 
upper layer of corn a short distance from the boiler-room bulkhead 
began to increase rap-

warm moisture laden air from hold 4 coming in contact with the cold 
outside air. When the cargo was discharged it was found that much 
of the corn had undergone severe deterioration during the voyage.
