were unequally developed though planted at the same time. 

 Some were earlier than others, and from notes recorded when 

 the samples were taken I have prepared the following table 

 showing in a concise form the relative condition at each pe- 

 riod. 



The Sanford and Pride of the North, the latter being a 

 dent corn raised in Minnesota, were about alike in earliness, 

 the Sanford being a little ahead July 26 and a little behind 

 Sept. 16, showing that the Minnesota corn is a little more rapid 

 "in growth, thus making it a little more certain in maturing its 

 seed. It will be seen from Table D that the Sanford increased 

 much more from July 26 to Aug. 5 than did the Pride of the 

 North, but for the next period the increase was reversed. For 

 the whole period, however, the increase was nearly the same. 

 With the Southern corn the increase of dry substance was very 

 marked up to Aug. 19, at which time its tassels were not in 

 sight. This rapid gain no doubt continued for several days 

 after this date. The total gain from July 26 to Sept. 16 is 

 greater in this variety than in either of the others. Because its 

 period of rapid increase is longer and if early frosts did not in- 

 terfere with the perfect maturity of this variety there is no 

 doubt but that it would produce a more profitable crop per acre 

 than any kind of corn thus far experimented with, but as a mat- 

 ter of fact this variety, in point of development, is in the same 

 condition Sept. 16 that ^the Sanford is a month earlier or the 

 Northern field corn forty days earlier. 



The Northern field corn increased less than either of the 

 other varieties, but this is more apparent than real for it was so 

 far developed July 26 that it had a large amount of dry sub- 

 stance, in fact its period of rapid increase was past, it being 

 fully twelve days ahead of the Sanford and Pride of the North, 

 and forty days ahead of the Southern.
