APPENDIX. xix 



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.

The dry weight of this species was not ascertained, 

 because the smallness of the produce renders it entire* 

 ly unfit for hay. If the nutritive powers of this species 

 be compared with those, of the preceeding, the in- 

 feriority will appear thus :

The comparative degree of nourishment which 

 the grass of the Festuca rubra affords, exceeds there- 

 fore that afforded by the F. ovina, in proportion as 1 1 

 to 14. 



From the trial that is here detailed, it does not seem 

 to possess the nutritive powers generally ascribed to it; 

 it has the advantage of a fine foliage, and may, there- 

 fore, very probably be better adapted to the masticat- 

 ing organs of sheep, than the larger grasses, whose 

 nutritive powers are shewn to be greater: hence on 

 situations where it naturally grows, and as pasture for
