48 BULLETIN 764, U. S. DEPARTMENT OF AGRICULTURE. 
along the bottom, the corn became badly damaged over and along 
the starboard tunnel. This is illustrated in figure 30. It will be seen 
in the cross section of hold 4 that samples Nos. 30 and 36, which were 
taken from the corn a short distance above the starboard tunnel, had a 
temperature of 132 and 128° F. and tested 36 and 46 c. c. in acidity. 
The corn in both samples had lost all vitality and was badly discolored. 
Compared to these, samples Nos. 37, 38, and 39, which were taken in 
the starboard tank from about thesame height, butsome distance away, 
did not exceed 65° F. in 
temperature and 19.5 
GHG, in} acidiiye. anal 
sample No. 35, which 
was taken from directly 
above the tunnel, but 
near the surface of the 
corn, had a temperature 
of but 85° F. Sample 
No. 29, which was also 
taken from above this 
tunnel, but near thesur- 
face of the corn, had a 
temperature of 90° F. 
Thestarboard shaft tun- 
nel, which had the two 
steam pipes in it, had a 
temperature inside the 
tunnel considerably 
higher than the tem- 
perature in the port 
shaft tunnel, which did 
not have any steam 
pipes in it. The corn 
surrounding the port 
shaft tunnel was

away from the tunnel, but it was not hot or discolored. Thesame con- 
dition of damaged corn along and over the starboard shaft tunnel, 
as found in hold 4, was also found in holds 5 and 6, as will be seen 
from the cross sections of these holds. Sample No. 49, which was 
taken from the corn about a foot from the starboard shaft tunnel in 
hold 5, had a temperature of 119° F., and an acidity of 37 c. c., while 
sample No. 47, taken from directly above it, near the surface of the 
corn, had a temperature of only 47° F., and an acidity of 21 c. c., and
