In the table the record of the observations on the blue grass is repeated. The actual 
number of experiments with the blue grass recorded is twenty five. Only one was un¬ 
successful. The blue grass seedlings were from 43 to 96 days old. 
Lolium perenne. 
English Rye grass is a valuable pasture grass and is grown 
abundantly associated with both the cereal grains and blue 
grass. Like the latter il forms a perennial green sward. It is, 
however, not closely related to either rye or blue grass and all 
attempts to infect it with conidia from these failed. Mildew 
has not been reported upon the English rye grass in this coun¬ 
try. The seed germinates quickly, the young seedlings coming 
out of the soil in about ten days. It is favorable for experi¬ 
mentation for the seedlings grow rapidly. They are bright 
green and very slender. The seed used seemed to be entirely 
pure.
