As shown in Table IV and figure 3, the car containing corn of 22 
‘per cent moisture which was shipped from Baltimore to Chicago and 
return lost 0.27 of 1 per cent, while the car containing the same kind 
of corn but which was held on the track at Baltimore lost 0.34 of 1 
per cent. The corn from lot No. 2, containing 19 per cent of moisture, 
showed a loss in weight of 0.21 of 1 per cent for the car en route from 
Baltimore to Chicago and return, as compared with a loss of 0.24 of 
1 per cent for the duplicate car held on the track at Baltimore. The 
reverse is true, however, of the corn containing 17 per cent of moist- 
ure. In this lot the shrinkage was 0.09 of 1 per cent in the corn in 
transit and only 0.04 of 1 per cent in the car of corn that remained on 
the track at Baltimore. It should also be noted in this connection 
that this lot of corn was of exceptional quality, showing the highest 
percentage of sound corn at the beginning of the experiment. The 
corn with 13.3 per cent of moisture lost 0.13 of 1 per cent in transit 
and 0.16 of 1 per cent on the track at Baltimore. As in the first ex- 
periment, the losses in weight of the four lots of corn used varied 
according to the moisture content of the corn, with the exception of 
lot No. 4. The fact that this lot of corn, which had an average 
moisture content of 13.3 per cent, lost more in weight than the corn 
that contained 17 per cent of moisture was probably due to the excep- 
tionally good quality of the corn in lot No. 3, or possibly to the ad- 
mixture of a larger percentage of finely broken corn in lot No. 4, 
although no leakage, even of the finely broken corn, could be de- 
tected in any part of the cars. 
As shown in Table IV and figure 3, the temperature of the corn at 
the time of loading it into the cars which were shipped from Balti- 
more to Chicago and return ranged from 30° to 34°, with an average
