APPENDIX. xv, 



Here then is a satisfactory proof f the superior 

 value of the crop at the time the seed is ripe, and of 

 the consequent loss sustained by taking it when in 

 flower; the produce of each crop being nearly equal. 

 The deficiency of hay in the flowering crop, in propor- 

 tion to that of the seed crop, is very striking. Its 

 superior produce, the highly nutritive powers which 

 the grass seems to possess, and the season in which 

 It arrives at perfection, are merits which distinguish it 

 as one of the most valuable of those grasses, which 

 affect moist rich soils, and sheltered situations; but on 

 dry exposed situations it is altogether inconsiderable ; 

 it yearly diminishes, and ultimately dies off, not un- 

 frequently in the space of four or five years.
