From the ahove details, which shew the produce and nutritive qualities of this grass, it 

 appears to be inferior to the Festuca duriuscula^ which will be manifest on a comparison of the 

 former details respecting the Festuca duriuscula, with the above. In regard to early produce, 

 however, this grass is superior. The herbage is uncommonly fine and succulent. But these 

 merits appear hardly suflficient to compensate for the deficiency of produce. If its merits he 

 compared with those of some of the early grasses, the Anthoxanthum odoratiim, for instance, it 

 will be found superior.
