SHRINKAGE EXPERIMENT. 



This experiment was conducted to determine the amount of shrinkage in 

 corn under ordinary conditions, A small crib holding about one hundred 

 bushels was built on a truck wagon. This was filled with corn duriog the 

 husking season and careful weights were then taken at the dates indicated. 

 The following table gives the net weights of corn, the percentage of shrink- 

 age to date, a,nd the number of pounds lost between the different number of 

 days. As the tables indicate, the percentage lost by shrinkage to February 

 27th was 12.60.
