26 HATCH EXPERIMENT STATION. [Jan. 



75 feet long) of each variety, with one or two exceptions 

 where not sufficient seed could be obtained, were planted. 

 The trial has involved a large expenditure of time and atten- 

 tion. Notes have been taken from day to day, covering 

 such points as germination, dates of tasselling and silking, 

 height, relative leafiness, time of cutting, etc. The autumn 

 was exceptionally unfavorable to curing of the corn crop ; 

 and hence, though an exact record of the weights of product 

 (sound hard ears, soft ears and stover) has been made, it is 

 of less value as a basis for comparative judgment than would 

 ordinarily be the case. Particularly is this true in relation 

 to the stover of the later Dent varieties. 



The field used for this trial was in corn last year. The 

 soil is a medium heavy loam, and quite even in quality 

 throughout. A fertilizer supplying , per acre, nitrate of soda, 

 72 pounds; dried blood, 120 pounds; dry ground fish, 80 

 pounds; plain superpltosphates , 480 piounds; and muriate of 

 potash, 240 pounds, was ajjjjlied broadcast after ploughing, 

 and harrowed in. The rows were uniformly spaced through- 

 out the field, viz., 3| feet apart. The corn was so planted 

 in checks that when thinned it stood, single plants, at the 

 following intervals in the row : for all Flint varieties, 8 

 inches ; for the earlier Dents, 10 inches ; and for the later 

 Dents, 12 inches. 



Without going into much detail, I have to report further 

 concerning this trial : — 



1. That the following pairs of varieties appear to be 

 nearly if not quite identical : — 



Champion White Pearl and White Pearl. 



Buckbee's No. 7 and Colossal. 



White Cap Dent and White Cap Yellow Dent. 



Sanford and White Flint. 



Rideout and Longfellow. 



Dibble's Early Mammoth and Houghton's Silver AVhite Flint. 



2. The yield of ear corn all or nearly all of which was 

 sound and well cured varied : for the Flint varieties, be- 

 tween 79 and 130 pounds; for the Dent varieties, between 

 78 and 144 pounds.
