The heavy shading represents heat-damaged corn as discharged. 
(Cargo No. 8.) 
As will be seen in figure 52 and Table. 
35, the corn which was located on the 
unprotected part of the shaft tunnel 
was influenced more by the tunnel tem- 
perature and tested poorer when dis- 
charged than the corn which was located 
on the plank-protected part of the tun- 
nel. They also show that the corn in 
either of the two positions on the shaft 
tunnel varied considerably more in tem- 
perature and tested poorer than the corn 
located at tunnel height but halfway 
between the tunnel and the side of the 
hold. The temperature of the corn at 
tunnel height near the side of the hold 
varied with the sea temperature as is illus- 
trated by the temperature record for ther- 
mometer 35. 
Three samples taken from hold 6 when 
the corn was being discharged tested under 
30 c. c. and eight samples tested over 30 
c. c. im acidity. 
The correlation of temperature changes 
and changes in the condition of the corn 
is illustrated in figure 53. 
CARGO No. 8. 
Cargo No. 8 consisted of 258,092 bushels 
of natural corn. The corn was loaded 
from February 27 to March 1, 1912. The 
steamship sailed March 1 and arrived at 
Rotterdam, Holland, on March 20, where 
the corn was discharged from March 20 
to March 22. The length of the ocean 
voyage was 19 days; the maximum time 
that any of the corn was in the vessel 
was 23 days, and the average time was 21 
days. 
STOWAGE OF THE CORN. 
The steamship had five cargo holds. 
As is shown in figure 54, this shipment 
was a full cargo, each hold being entirely 
filled with corn.
