variety, and 36.5 per cent greater than that of the late one. The 

 same relative relation exists between the leading varieties of the 

 different groups for the four years 1909, 1911, 1912, and 1913, when 

 both the actual and computed yields can be compared.

LEADING VARIETIES. 



Of all the varieties tested, a few which have proved to be best 

 adapted should be more generalty grown. A knowledge of the 

 characteristics of the leading varieties will enable the farmer to 

 decide which is best for him to grow. There is a wide range in the 

 time of maturity of the different varieties of oats, thus enabling the 

 grower to choose the one which best fits into his farm practice. 



THE MEDIUM-EARLY GROUP. 



Of more than 30 varieties of medium-early oats which have been 

 tested at Dickinson, the Early Mountain, Golden Eain, and Victory 

 have so far proved superior.
