* The average of previous years. 



The foregoing figures show a large variation in production in 

 different years, under conditions other than the season, quite 

 uniform. This variation is not alone in gross weight of crop, but 

 in dry matter as well. The largest quantity of dry matter pro- 

 duced in any case during the five years is nearly three times that 

 yielded by the smallest crop. This is in part due to manuring and 

 cultivation and in part to the character of the season. 



Had these experiments been discontinued after 1891 the out- 

 come would have been decidedly favorable to the large variety of 

 Dent corn, but in 1892 and 1893 the relation of yield has been re- 

 versed and the smaller variety of Flint coi'n has taken the lead. It 

 is probable that another five years' series of comparisons would 

 furnish a somewhat similar experience.
