rye grass. It is a short-lived perennial bunch grass. It killed out 
here during the winter of TOO 20 lat does not live under normal

sown with a grain drill at the rate of from 10 to 15 pounds: per acre. 
W estern Ww vheat orass is the common ‘‘wheat grass” or “‘blue- 
joint” of the plains. It is a valuable hay grass and yields well in 
native stands in the lower places. It does not lend itself to cultiva- 
tion. The seed is low in germination and is not known to be on the 
market. Western wheat-grass was sown in rows, but it soon spread 
into a solid mat by means ; of its rootstocks. 
MILLET 
Different varieties of millet were grown from 1914 to 1920, in- 
elusive. Millet makes good hay. It can be seeded late. It is val- 
uable as a catch crop. Im case of an early failure of some crop, 
millet can usually be sown. The millet varieties were sown here 
with a grain drill at the rate of 15 pounds per acre during the latter 
part of May or the first week in June. 
TaBLe 23.—YVields of field-cured hay from drilled plats of seven varieties of millet.
