At each locality the com from all the experiments was harvested the 

 same day; and the weight of ears, together with the number of plants, 

 was recorded for each row. 



To avoid, so far as possible, differences due to inequalities of soil and 

 to obtain reliable averages, each pair of rows consisting of one row each 

 of Maryland- and Texas-grown seed was considered a separate test. The 

 relative behavior of the plants from the two sources of seed was deter- 

 mined by an average of all the comparisons, usually lo in number. 



In Table I are given the yield in pounds per row and the yield per plant 

 from the several rows. Yields which stand opposite in the table are 

 from adjoining rows in the field.
