variety was grown. The series were duplicated in all years, making 

 a total area for each variety of about one twenty-fifth of an acre. 

 The yield in pounds of ears for each plat and the total yield of each 

 variety are shown in Table IV. In that portion of the table relating 

 to 1913 and 1914 the yields of check plats are totaled by twos, to 

 correspond with the total yields of varieties. Yields per acre, the 

 ranking of varieties, and the variety classes are given in the sum- 

 mary. The rankings in 1912 are according to average yields of dry 

 ears for the plats of each variety. The rankings for 1913 and 1914 

 are according to the amount the average yield of the two plats of 

 each variety exceeds the average of the four check plats adjacent 

 to them.
