The results of two tests in which St. Charles was the most 

 productive variety are unavailable for the above compilation 

 because published only in the form of a summary. If these 

 figures could have been used, St. Charles would have ranked 

 higher, possibly first, instead of fourth, in the above table. 



Three of the varieties standing near the head of the list, 

 Cocke Prolific, Mosby Prolific, and Blount Prolific, bear 

 several small ears on each stalk. 



III. Seed Coen from Different Latitudes. 



Early in 1896 Hickory King corn was obtained from 

 Illinois, Delaware and Alabama, and Blount Prolific corn 

 from Illinois and Georgia. Six plots, each one- tenth acre 

 in area, were used for this experiment ; plots 1 and 4 were 

 both planted in Hickory King corn grown in Alabama, the 

 purpose of this duplication being to learn whether the dif- 

 ferent plots were nearly of uniform fertility. 



Preparation, fertilization, and culture were the same for 

 all plots. The young plants were thinned so as to leave the 

 same number on each plot, the distance between plants 

 averaging 2.4 by 4.5 ft., which is at the rate of about 4,000 

 plants per acre. 



The following table gives the locality from which seed 

 was procured, the yield of shelled corn per acre on each 

 plot, and the increase or decrease of Northern seed over 

 Southern seed :
