SHRINKAGE OF SHELLED CORN IN CARS IN TRANSIT. 5 



the other four cars did not show an increase; in fact, the tempera- 

 ture of the corn in two of the cars decreased slightly. 



Figure 2 also shows that the mean daily air temperature from 

 April 21 to April 27 was much lower than the average temperature 

 of the corn in any of the cars, varying from 36 to 40 degrees. As a 

 result of this low air temperature the temperature of the corn in all 

 of the cars decreased slightly, except that in car No. 1, which

showed an increase form 79° on April 21 to 135.5° F. on April 27, 

 the deterioration being so rapid as to overcome or conceal any in- 

 fluence of the air temperature. The highest temperature of the corn 

 in car No. 1 was 112° F., which was reached on May 3. On May 7 the 

 average temperature was 139° F. This temperature prevailed until 

 May 11, at which time the corn was unloaded and found to be very 

 badly damaged.
