80 BULLETIN 402, U. S. DEPARTMENT OF AGRICULTURE. 
The average dates of heading and maturity, height, yield of grain 
and straw, and weight per bushel of five varieties of barley which 
were grown at the Akron Field Station during the 8-year period 
from 1908 to 1915, inclusive, are given in Table XXI. The average 
yields are shown graphically in figure 9. Blackhull (C. I. No. 878) 
has averaged five days earlier in maturing than Coast (C. I. No. 690). 
The ripening date of Blackhull is July 15, and that of Coast July 20. 
Hannchen (C. I. No. 602) and Hanna (C. I. No. 226) are still later, 
averaging July 22 and July 24, respectively. 
The quality of grain, as shown by weight per bushel, puts Hannchen 
in the lead and Hanna a close second. Although the Coast barley 
has a plump, heayy grain, it does not thrash clean. The fragments

39 pounds per bushel, or 9 pounds below the standard weight. The 
straw weights do not vary sufficiently to need comment.

NURSERY EXPERIMENTS. 
The nursery tests with barley have included 75 varieties and nu- 
merous strains. The object has been to discover valuable new 
material, and when a variety or selection did not prove itself supe-
