SHRINKAGE OF SHELLED CORN IE" CARS IN TRANSIT. 3 



placed in the corn in different parts of the car, in order that the tem- 

 perature of the corn at those points could be ascertained at any time 

 during the experiment without opening the car, the thermometers 

 being connected with wire leads which extended to the outside of the 

 car. The average condition and quality of the corn in each car at 

 the beginning of the experiment, as represented by the analyses of 

 samples taken when the corn was loaded into the cars, is shown in 

 Table I.

As will be seen by Table I, the average moisture content of the 

 corn when loaded into car No. 1 was 19.8 per cent. The corn in 

 car No. 2 contained an average of 18.6 per cent of moisture. The 

 corn in car No. 3 was a mixture of the same kind of corn as that 

 contained in cars No. 2 and No. 5, the average moisture of the mix- 

 ture being 17.8 per cent. The average moisture content of the corn 

 in car No. 4 was 17.4 per cent, and the corn in car No. 5, which had 

 been artificially dried, contained an average of 16.7 per cent of 

 moisture. 



SHRINKAGE IN THE WEIGHT OF THE CORN. 



The amount of corn placed in each car and the shrinkage in weight 

 while the corn was in the cars from April 14 to May 11, 1910, to- 

 gether with the average temperature of the corn in each car at the 

 time of loading and unloading, are shown in Table II.

 5 cars of corn used in the first experiment.
