its value - - -- - - 101 0 8 
The proportional value which the grass, at the time of 
flowering, bears to that at the time the seed is ripe, is as 
6 to 8. 
This species is smaller in every respect than the preced- 
ing. The leaves are seldom more than from three to four 
inches in length ; it affects a soil similar to that favourable 
to the growth of the Festuca ovina , for which it would be a 
profitable substitute, as will clearly appear on a comparison 
of their produce with each other.

The proportional value which the grass of the latter- 
math bears to that at the time the seed is ripe is as 6 to 8, 
and is of equal value with the grass at the time of flowering.
