s is shown in Table 29 
and figure 42. The 
temperature record for 
thermometer 23 shows 
that the corn at the 
surface near the en- 
gine room bulkhead 
mcreased 27° F. and 
had a temperature of 
80° F. at the end of 
the voyage, while the 
temperature of the 
corn at the same 
height in the after part 
of the hold was the 
same when discharged 
as when loaded, as 
shown by the tempera- 
ture record for ther- 
mometer24. The corn 
stowed next to the 
engine-room bulkhead 
about 6 feet from the 
bottom, increased 8 
degrees, and the corn 
stowed at the same 
height in the after 
part of the hold in- 
creased 7 degrees, as 
is shown by the rec- 
ords for thermome- 
ters 35 and 37. The 
effect of the engine heat on the corn is shown in Table 30.
