 in proportion to their length. The grain is long and slender

MEDIUM LATE VARIETIES WITH WHITE GRAIN AND SPREADING 



HEADS. 



The great majority of oat varieties grown in this country 

 belong to the medium oats with white grain and spreading 

 heads. While there is some sHght variation in the time of

maturity they all ripen under our conditions in from 95 to 100 

 days from the time of planting. On the basis of type of kernel 

 these varieties may be still further subdivided in two groups. 

 The distinction between these sub-groups is not very marked 

 and for that reason was not included in the scheme of classifica-
