As shown in Table VI and figure 4, the shrinkage, or loss in weight, 
of the corn varied according to the moisture content. The corn 
containing 21.6 per cent of moisture lost 0.58 of 1 per cent when en 
route from Baltimore to Chicago and return, while the duplicate car 
of corn held on the track at Baltimore showed a shrinkage in weight 
of 0.59 of 1 per cent. The car of corn which contained 19.9 per cent 
of moisture lost 0.24 of 1 per cent in transit, while the duplicate lot 
in the car which was held on the track at Baltimore showed a loss of 
0.26 of 1 per cent. The corn from lot No. 3, containing 17.4 per cent 
of moisture, showed the same shrinkage in transit as the car of corn 
which remained on the track at Baltimore—0.28 of 1 per cent. The 
corn from lot No. 4, containing 14.1 per cent of moisture, showed 0.15 
of 1 per cent loss in weight while on the car in transit, as against 0.11 
of 1 per cent loss on the corn in the duplicate car at Baltimore. 
in this experiment the losses in weight were practically the same 
on the cars of corn in transit as on the cars held at Baltimore. By 
consulting the temperature records shown in figure 4 it will be seen 
that there was not such a marked difference in the air temperatures 
at Baltimore and at western points during the third experiment as 
‘occurred in the second experiment, which is illustrated in figure 3, 
page 9. The air temperature through which the cars passed en 
route from Baltimore to Chicago and return was lower on several 
days than the air temperature at Baltimore, but this difference oc- 
curred only for three or four days at most, and on several days the 
air temperature surrounding the cars in transit was higher than the 
air temperature at Baltimore. The difference between the air tem- 
perature at Baltimore and at western points during this experiment
