before the corn in this hold was discharged. Compared with the hot 
corn, samples Nos. 6 and 7, taken from the corn near the surface 
on the port side of the hatch, had a temperature of but 57° and 59° F., 
an acidity of only 23 c. c. each, and a germination of 54 and 52 per 
cent, respectively. None of the remaining samples taken from the 
hold had a temperature higher than 59° F. 
Hold 4 was about half filled with corn. In the lower part of the 
hold there was a water tank, extending across the hold against the 
forward bulkhead,
