Obs. This species affords an indifferent pasture in the latter — of 
summer ; but it is not of much worth. It is better to supersede these 
and all grasses of inferior quality—by the i slbegnie rma of more valua-

soil is enriched and properly managed, the bette mg nds of natural 
Grasses (especially Poa and Festuca) soon come in fapauenccnils and 
expel the others.
