CARRYING QUALITIES OF EXPORT CORN. 15 
from 64 to 77° F. in temperature and when discharged tested 34.7 
c. c. in acidity, 67 per cent in germination, 76.1 per cent in sound 
kernels, and 51.75 pounds in weight per bushel. 
Sample No. 57, 
taken from near the side of the hold, a little over halfway down in 
the corn on the port side, had a temperature of 125° I’. and tested 
51.8 c. c. in acidity, 6 per cent in germination, and 5.5 per cent in 
sound kernels. The corn along the top of the shaft tunnel varied in 
temperature during 
the voyage, while the 
temperature of the 
corn thesame height in 
the hold located half- 
way from the tunnel 
and theside of the boat, 
remained nearly the 
same throughout the 
voyage, as is shown by 
comparing the temper- 
ature records for ther- 
mometers 25 and 26. 
Table 34 shows that 
the corn surrounding 
thermometer 25, which 
was located on theshaft 
tunnel, tested higher 
by 2 c.c.in acidity and 
lower by 67 per cent in 
germination than the 
corn surrounding ther- 
mometer 26, which was 
located at tunnel 
height but halfway be- 
tween the tunnel and 
the side of the hold. 
Four samples taken 
from hold 5 tested un- 
der 30 c. c. and nine 
samples tested over 30 
c. c. In acidity.
