SHRINKAGE OF CORN IN STORAGE. 



The average condition and quality of the 500 bushels of corn at the 

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

 analyses of samples taken from the various drafts at the time the 

 hopper of the scale was being filled, are shown in Table I.

 500 bushels. The 

 weight per bushel 

 was 54.5 pounds in 

 the third and fifth 

 drafts and 54.8 

 pounds in the first, 

 second, and fourth 

 drafts, the average 

 for the entire lot 

 being 54.7 pounds. 

 The average percent-

 was 97.1 percent and 

 the average percent- 

 age of germination 

 was 89.6 per cent. 



SHRINKAGE IN THE WEIGHT OF THE STORED CORN. 



Weighings and temperature records were made of the corn at 

 frequent intervals throughout the experiment, during which time 

 consideration was also given to the temperature and relative humidity
