TESTS OF [BARLEY VARIETIES 11^ AMERICA 159 
however, spring sorts appear to be worthy of extensive trials on the 
southern Coastal Plain. Yields equal to those obtained in Minne- 
sota and Wisconsin can hardly be expected, as the soil type is not 
one to wliich barley is well adapted, and the climatic conditions are 
unquestionably more adverse. 
East of the Mississippi River there is a conspicuous gap between 
the winter and spring areas. Spring barley is at present grown 
extensively in northern Illinois, Indiana, and Ohio. South of this 
section little barley, either spring or winter, is grown until the winter- 
barley district of Tennessee is reached. On the Great Plains the 
spring-sown semiarid forms and the fall-sown humid forms of the 
Tennessee Winter type overlap. In western Oklahoma and south- 
western Kansas both types are grown. Winter barley also is culti- 
vated on the Plains in Texas. 
WELL-KNOWN OR PROMISING VARIETIES 
At various times varieties of barley have been introduced into the 
United States or developed at the agricultural experiment stations. 
Some of these disappeared quickly, while others were tested for long 
periods at many stations. The number of varieties which had been 
tested up to 1921 was so large that no attempt has been made to 
describe them individuall}^. From this number, however, a few of 
the more important and better known varieties were chosen for the 
purpose of amplifying the meager details mentioned in describing 
the results at the several stations. 
The varieties are not presented in the order of their Cereal Investi- 
gations (C. I.) numbers. This arrangement, perhaps, would have 
been the most desirable in checking references arising within the text 
of the bulletin. For any question arising outside this discussion the 
varieties are more easily found when arranged in related groups. 
Thus, in the following descriptions the Chevalier barleys are grouped 
together, as are the Manchuria varieties, etc. Where it is desired to 
check varieties by the Cereal Investigations numbers they will be 
found in numerical order in Table 99, in which also is inserted a 
reference to the varietal description under this heading. 
TWO-ROWED HULLED AWNED BARLEYS 
CANADIAN THORPE (C. I. NO. 740) 
A variety known as Canadian Thorpe has been widely tested at 
stations in Canada and has been grown on a few experiment stations 
in the United States. It is a barley of the Thorpe type. According 
to Dr. C. E. Saunders, " Canadian Thorpe was introduced into Can- 
ada many years ago by a Canadian seedsman and is essentially 
identical with Duckbill.^' The original Canadian Thorpe produced 
good yields in the western prairie Provinces. Selections were made 
from the Canadian Thorpe, which Seager Wheeler, of Rosthern, 
Saskatchewan, considered to be superior to the original variety. 
This barley was grown at Moccasin, Mont., for three years. During 
these years its yield was 98 per cent of that of the weighted mean of 
all varieties.
