Agricultural College at Guelph, Ontario. It has been widely dis- 
tributed by the Minnesota station. The Manchuria and Oderbrucker 
barleys have the six rows of grains arranged about the rachis to 
form a head which is square in appearance; hence the group to 
which they belong is often called " square head " or " four-rowed.'' 
Minnesota No. 105 has yielded better at Highmore than Minnesota 
No. 6. which is another stock of the Manchuria variety. Minnesota 
No. 105 was not grown at Brookings until 1912, when it yielded 
58.3 bushels to the acre. As shown by Table XY, Minnesota No. 105 
contained 16.7 per cent of protein, weighed 25.1 grams per 1.000 
grains, and exceeded Oderbrucker in weight per bushel by 3

pounds in the Highmore crop of 1910. It seems to be more vigorous 
and resistant under severe conditions than Oderbrucker, though the 
latter variety is probably as good in favorable seasons. Everything 
considered, it seems certain that more attention to this variety in 
the eastern district of South Dakota would improve the barley crop. 
Odessa.— The Odessa (S. Dak. No. 182, C, I. No. 182) differs from 
the Manchuria in that it matures about a week earlier. There is 
little difference in the appearance of the plants or the heads. A 
number of selected heads of Odessa barley are shown in figure 10. 
It has yielded well in the trials at Brookings, excelling all other 
varieties on trial, except Kitzing, during the last eight years. In 
1912 the Odessa yielded 1.1 bushels less than the Manchuria (Minn.
