4 BULLETIN 1398, U. S. DEPARTMENT OF AGRICULTURE 
At the termination of this test the cars were released for regular 
road service and were not recalled until June, 1924, when they 
were sent to Florida to be tested the second time. On June 9 the cars 
were pre-iced at Haines City, Fla. The following day car A was 
loaded at Winterhaven and car B at Florence Villa, and both were 
consigned to New York. The temperature of the fruit placed in 
car A was 87° F. and that in car B 79.5°. The fruit in car A 
was freshly packed when loaded, but that in car B had been held 
in a packing house. 
The first re-icing was at Lakeland, Fla., and the last at Potomac | 
Yards, Va. The total quantity of ice supplied during this second :

Fic. 3.—Front elevation of divided bunker of the woven-wire type, show- 
ing the main and the intermediate or secondary partitions 
test, including pre-icing, was 19,457 pounds for car A and 23,091 
pounds for car B, or a total saving of 3,634 pounds for car A. 
The measured ice capacity of the bunker of car A is 3,100 pounds 
less than that of car B. In the first test, car A not only saved this 
difference but 960 pounds in addition, while in the second test it 
saved 534 pounds more than this difference. 
TEMPERATURES MAINTAINED 
The basis for comparison of the temperatures maintained is the 
actual temperature of the fruit at the top and bottom layers of the 
load at the doorway, at the bunker, and in the middle layer at the
