WORK OF 1909. 



Eleven varieties of corn represented by 10 ears of each were used. 



The seed of the ears was not mixed, but planted in adjacent rows. 

 The corn was dropped in hills, and two stalks, from 6 to 8 inches 

 apart, were left in a hill. 



Each liill represented two ears. In all 10 rows representing a vari- 

 ety the first plant in each hill was from the same ear. These plants 

 served both as a standard of comparison and as a sire to the variety 

 in that set of 10. The second plant in all hills of any one row repre- 

 sented one ear of a female parent and was detasseled. 



Duplicate plantings were made from each of the ears. In one 

 instance the standard or sire ears were of the Marlboro Prolific variety, 

 and in the other instance the standard or sire ears were of the Rodgers 

 Wliite Dent variety. 



The standard or sire ears used were also grouped and detasseled 

 the same as the ears of the other varieties, so that a study of both 

 the male and the female was afforded. Furthermore, by thus com- 

 paring the standards of all the varieties in the test the several varieties 

 themselves could be compared. 



The arrangement of the varieties with their pollen-bearing stand- 

 ards is given in Table XIV. The two fields in wliich the crossing 

 was accomplished were well isolated.

CHARACTER OF THE SOIL. 



The crossing was accomplished in 1909 at Statesboro, Ga., on 

 coastal plain oand. The soil where the Marlboro Prolific sire was 

 used had a fairly compact, sandy, clay subsoil 10 to 12 inches below 

 the surface, and the land was fairly fertile. The soil where the 

 Rodgers White Dent sire was used had less clay in the subsoil, and 

 the land was naturally less fertile.
