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 XV, 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.
