season of the year. The average moisture content of the corn in lot 
No. 2 was 17.8 per cent. In lot No. 3 the average moisture content 
was 16.9 per cent, while in lot No. 4 the average moisture content 
was 13.9 per cent. The average proportion of sound corn in each lot 
ranged from 88.9 per cent in lot No. 1 to 96.2 per cent in lot No. 4. 
di will be noted that the average percentage of badly broken corn was 
very high in lot No. 4, being 22.1 per cent.

Fic, 5.—Diagram showing the loss in the weight of the corn, the average temperature 
of the corn in each of four cars in transit from Baltimore to Chicago and return, and 
also the mean Gaily 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 Baltimore in 
the fourth experiment. 
3, 1911, and the average temperature of the corn in each car at the 
time of loading and unloading are given in Table VIII. These same 
factors, together with the mean daily air temperatures to which the cars 
were exposed and the average temperature of the corn in the various 
cars throughout the experiment, are shown more in detail in figure 5.
