Figure 6 shows the fruit temperatures maintained at the bunker 
and doorway positions on the top and bottom layers in the second 
test. The temperatures in car A at the bunker were slightly higher 
in both the top and bottom positions than those in car B, although 
the initial fruit temperature was 7.5 degrees higher than in car B. 
The cars show a parallel and abrupt drop in temperature from the 
time of loading until midnight of the first day, when the drop begins 
to steady and the curve flattens out. The difference between cars A 
and B at 6 a. m. of the second day was 7 degrees, approximately the

same as that between the initial fruit temperatures, and very slowly 
diminished, until on the last day the temperatures were practically 
the same. At the top position a more gradual cooling is seen, but 
from the beginning of the test until about noon of the third day there 
remained a difference of 7 degrees. This difference diminished 
slowly but remained marked at the end of the trip. Both cars had 
practically the same temperature until the last reading, when car A 
showed a slightly lower temperature. At the top doorway position 
car B showed an average about 1 degree lower than car A. In the 
bottom position at the beginning of the trip the fall in temperature 
was sharp and may be favorably compared with the drop in the
