5 feet below the surface and the remainder of the corn in the hold, 
excepting that which was located on and near the shaft tunnel, 
changed but little before the cargo arrived in Denmark, as is <i 
by the temperature records for thermometers 38 and 41. But, 
during the discharge of the cargo, which took 15 days, the corn 
at the new surfaces formed from day to day would frequently get hot 
from one day to another. Thus the corn nearly halfway down in 
the hold was cool 
and sound when it 
was firstexposed but 
got hot before it was 
discharged, as is 
shown bysample No.

It will be seen in

Acidity, 26.3. ¢. ¢., 
germination 29.9 per

72.9 per cent, and

50.6 pounds, which 
was an average in-

INFLUENCE OF TUNNEL HEAT. 
The temperature of the corn located next to the shaft tunnel in 
holds 4 and 5 was noticeably affected by the tunnel temperature, as 
is shown in figures 26 and 27. The tunnel was constructed from 
steel and was unprotected, excepting that part of it which was
