IOWA SILVER MINE 



History — The Iowa Silver Mine variety of com 

 was originated by Mr J. H. Beagley of Ford county, 

 Illinois, from seed selected from a prize-winning ex- 

 hibit of white corn at Ford county farmers' institute 

 in 1890. After sufficient com had been grown to plant 

 a twenty-acre field, the crop was sold to the Iowa seed 

 company, which named it Iowa Silver Mine, and sold 

 large quantities of seed to Illinois farmers. The orig- 

 inator has selected toward a creamy white color, cylin- 

 drical shape; tapering slightly at tip, with an average 

 of about eighteen rows of kernels. This variety has 

 been developed by selection, no crossing or mixing of 

 varieties having occurred. The variety characteristics 

 are strong, especially in those strains grown in the 

 northern division of the state. The variety is from 

 medium to early maturing, maturing in one hundred 

 to one hundred and ten days, adapted to the north 

 half of the central and the northern section of the 

 state.

 partly slowly tapering; 2, circumference 7.2 inches,
