 the corn in each of four cars in transit from Baltimore to Chicago and return, and 

 also the mean daily air temperature through which the cars passed, as compared 

 with the same factors on the four duplicate cars of corn held on the track at Balti- 

 more in the third experiment. 



deterioration was due almost entirely to the high moisture content of 

 the corn, which became hot in the cars as a result of fermentation 

 and the development of molds. On March 22 the average tempera- 

 ture of the corn in each of the two cars was approximately 55° F. 

 At the end of the experiment the a Average temperature of the corn in 

 the car that remained on the track at Baltimore had increased to
