From Table XI it is seen that several varieties appear to be better 
than the Pacific Bluestem from the standpoint of yield. The Early 
Baart exceeded that variety during the five years by an average 
yield of 3 bushels per acre. The Koola variety exceeded the Bluestem 
in the 3-year average yield by 6.3 bushels per acre, and for the same 
period the Karun exceeded the Bluestem by 4.9 bushels per acre. 
In Table XII the leading spring wheats grown at the Moro sub- 
station during 1913, 1914, and 1915 are arranged in several classes, 
showing the average yield for each variety and for each class.

Table XII shows that the durum wheats apparently are not so well 
adapted to the Columbia Basin region as are the common and club 
varieties. The bearded varieties of common wheats exceeded the yield 
of the beardless common and club varieties by 1.7 bushels per acre, 
and the average yield of all common and club wheats exceeded the 
average yield of the two durum varieties by 3.5 bushels per acre. 
DESCRIPTIONS OF THE BEST VARIETIES. 
The six varieties of spring wheat which have given the best average 
results are described and discussed below. Of these varieties, Pacific 
Bluestem and Little Club are well known and widely grown west of 
the Rocky Mountains. Early Baart is grown commercially to a small
