8 A NEW BASIS Fdi; BARLEY VALUATION AND [IMPROVEMENT. 
endosperm, the percentage of nitrogen, etc, as well as some very 
weighty agricultural considerations having to do with yield, stiffness 
of 'straw, etc. But whatever other elements of quality enter into 
our work of Ameri- 
can barley improve- 
ment, the scutellum, 
as the most potential 
part of the barley 
grain, is likely to he 
one. 
How far this is ca- 
pable of modification 
is at present unde- 
termined. But the 
opinions of those ex- 
perimenters in grain 
breeding both here 
ami in Europe who 
•have been consulted 
on this point agree 
that there is no a 
priori reason why this 
particular form of 
plant structure should 
not be as plastic and 
capable of improve- 
ment as any other. 
The general success in 
plant breeding, ac- 
cording to modern methods, leads us to expect that in our work of 
barley improvement now going on at St. Anthony Park, Minn., we 
shall secure results of distinct value to American agriculture.
