1 Sample was located on the shaft tunnel. 
*A verage for these two samples. 
2 Sample was located same height as No. 34, but halfway between shaft tunnel and the sides of the hold. 
The effect on the corn of the heat from the engine room which 
penetrated through the shaft tunnel in the bottom of the hold is 
shown in Table 31. 
The corn located di- 28.2436 
rectly on the shaft 
tunnel increased 27° 
F. during the voyage, 
while the corn located 
the same height as the 
tunnel, but halfway 
between the tunnel 
and the sides of the 
hold, increased 7 de- 
grees on the port side 
and 8 degrees on the 
starboard side, as is 
shown in figure 43.

the shaft tunnel was musty, somewhat moldy, and “packed.” The 
corn in the hold ranged from 50° to 85° F. in temperature and 25.5 
to 32.7 c. c. in acidity (4 samples tested slightly over 30 c. c. and 
12 samples tested under 30 c. c. in acidity), from 7 to 52 per cent in 
germination, and from 57.9 to 95.6 per cent in sound kernels. 
The corn in hold 5 as discharged varied from 44° to 120° F. in 
temperature, from 22.9 to 54.9 ¢. ¢. in acidity, and from 5 to 66 per 
‘cent in germination. A small amount of the corn a few feet under
