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. 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,

averages for the samples taken from the corn located at a height even 
with the top of the shaft tunnels are shown in Table 23. It willbeseen 
that those samples which represented the corn stowed next to the water 
tank had on an average a higher temperature by 23° I’., more acidity 
by_10.3 ¢. ¢., was poorer in germination by 33.2 per cent, had less 
sound kernels by 29 per cent, and had a lower test weight by 3.1 
pounds per bushel than sample No. 20, which represents corn stowed 
some distance back from the tank and away from the shaft tunnels.
