VARIATION STUDIES IN BROME GRASS

propagation in order to be able to establish the type in any community 
to which it is adapted. 
A few of these types which have proved themselves to be pure 
line types are being grown in small fields in some of our high altitude 
locations. They are thus being observed under actual farming condi¬ 
tions. This part of the work of necessity progresses slowly at first, 
until a strain proves itself in a locality and people commence to desire 
the seed in order to get the same desirable strain. 
While these phases of the subject are being studied, studies upon 
the variations occurring in the different strains are being made. It 
may be interesting to call attention to some of these variations at the 
present time, altho the studies are not completed and will not be for 
some little time in the future. In the illustrations which follow, pic¬ 
tures are shown of some of these types, selected to illustrate variations 
which occur. These pidtures illustrate differences to be noted both in 
the mature or seed stage of the crop and in the spring condition of the 
crop. A comparison will show that these differences are maintained 
thruout the growing period.
