quarter length of the cars. In addition, the average fruit tempera- 
tures of the top and bottom layers of the load are considered. The 
positions in the cars at which the temperatures were taken are the 
same in both tests and are in a vertical plane, equally dividing the 
car longitudinally. The initial readings shown on the accompanying 
charts (figs. 4 to 7), are the fruit temperatures at the time of 
loading. 
Figure 4 compares the temperatures maintained in the top*and 
bottom layers at the doorway and bunker. Inasmuch as there is not 
so large a difference between the top and bottom layers at the door- 
way of car A as between the top and bottom layers of car B, the 
record is in favor of car A. Car B registered a temperature 1 degree

Fic. 4.—Fruit temperatures, first test. at top and bottom layers of the load at 
doorway and bunkers. The order of cars is that in which they were iced 
lower on the bottom layer at the doorway than car A, but car A was 
cooler at the top layer by about 2 degrees. 
At the top and bottom layers at the bunker, car A maintained 
a slightly higher temperature than car B; however, the greatest 
difference was noted in the top layer during the first five days. A 
greater fall occurred in car A by midnight of the first day than in 
car B, but the latter fell slightly lower than car A and maintained a 
gain of approximately 2 degrees throughout the trip. 
Attention must be called to the initial fruit temperature at loading. 
The temperature of the fruit loaded in car A averaged 78° F. 
and that in car B 70.5°. Consequently, the fruit in car B had 
the advantage of being 7.5 degrees cooler at the beginning of the 
test. Had this initial temperature been the same, then in all 
probability the two cars would have shown the same temperature at 
the top layer, but car B would have been approximately 5 or 6
