the Manchuria, is a bearded wheat which does not belong to any 
group now commonly grown in this country. 
Table X shows the average date of heading and of maturity, 
height, and weight per bushel of these 10 varieties in 1908, 1909, 1910, 
and 1913. In 1911 none of the varieties matured grain, so that 
none of these data are available for that year, while in 1912 data 
were obtained for 
only two or three 
varieties.

straw is for five years, 1912 being excluded for the reason that only two

LEADING VARIETIES OF SPRING WHEAT. 
As shown in Table X, the best yields of spring wheat at Newell have 
been obtained from the durum varieties, Kubanka and Arnautka. 
Some of the varieties of common wheat, however, have produced
