crop till the seed be ripe exceeding one half of its value 558 5 3 



The proportional value which the grass at the 

 time the seed is ripe, bears to that at the tijne of flower- 

 ing, is as 6 to 14, nearly.

The proportional value which the grass of the 

 latter-math bears to that at the time of lowering, is as 

 5 to 14, and to that at the time the seed is ripe, 5 to 6. 



The above particulars will confirm the favourable 

 opinion which was given of this grass when speaking 

 of the Festuca hordiformis, and F. glabra. Its produce 

 in the spring is not very great, but of the finest <jquali- 

 ty^ and at the time of flowering is considerable. If it 

 be compared with those affecting similar soils such as 

 Poa pratensis, Festuca ovina, &c. either considered as 

 a grass for hay, or permanent pasture, it will be found 

 of greater value.
