﻿REFRIGERATION OF DRESSED POULTRY IN TRANSIT.

beginning of the haul, but failed to hold. Samples from lliis position 

 fall, by chemical analysis, into group 1, Table 2. The efficiency of 

 the car is represented by 1.05. 



Figure 13, c, d, of cars belonging to type C, are the records of 

 Experiments 2085 and 2099, respectively. Experiment 2085, with 

 an outside temperature averaging 72° F. (22.2° C), gave an efficiency 

 of 1.01; Experiment 2099, with the atmosphere averaging 61° F. 

 (16.1° C), is represented by 1.02. The analyses of the poultry 

 carried at the bunker ends of these cars are found in group 2, Table 2. 



Figure 13, e,f, pre- 

 sents records of sam- 

 ples belonging ' to 

 Group III, figure 1. 

 The cars were of 

 type D. The records illustrate the 

 effect of long service on cars which 

 were at one time excellent refrigerators. 

 These two cars are of a very old series 

 of this type and seem to have lost 

 their efficiency through the continual 

 wear and tear to which they are sub- 

 jected. Their efficiency was 0.56 and 

 0.87, respectively, as compared with 

 1.19, the average for their type. The 

 atmospheric temperatures averaged 

 70° F. (21.1° C.) and 77° F. (25° C), 

 respectively. The goods at the bunker 

 end of these cars show the effects of 

 high temperatures, as may be seen by 

 reference to group 3 

 of Table 2, or column 

 3 of figure 2. 



Figure 13, g, Ji, 

 shows records of ship- 

 ments which yielded samples of Group IV, figure 1. The cars 

 were of type B, efficiency, 0.60 in each case. The records shown 

 as figure 13, g, were made in a comparatively new car, when 

 the outside temperature averaged 74° F. (23.3° C). It was 

 possible to reduce the bunker to a low temperature at the begin- 

 ning, but as soon as the car started on the trip the temperature 

 began to rise and never receded. The temperature at the center 

 was never low. The records in figure 13, h, were both high at all 

 times. This was an older car of type B. The outside temperature 

 averaged 73° F. (22.7° C), with a maximum variation of 17° F. 

 The differences between bunker end and center are practicallv lost
