iiO 



I liave now enumerated all the grasses with which I am 

 acquainted, that hold out any reasonable probability of re- 

 paying the labour and expence of cultivation. I have in- 

 cluded a few, from which I have but slight hopes ; yet as 

 these also have their partizans, I have brought them forward, 

 chusing to leaving the question relative to their merits open 

 for further examination and future experiment. 



I proceed to some other species of grass often recommended 

 as valuable in modern agricultural books, but of which I 

 entertain a different opinion, and upon these having had 

 ample opportunity for experiment and observation, I shall 

 venture to pronounce a condemnation without hesitation. 



XIII. POA TllIVlALIS 



I commence with the rough stalked meadow grass, to which 

 I have paid more attention than to any other grass, seduced 

 by the plausible appearances it often held out. 



For instance, lively and luxuriant tufts in my collectitious 

 plots, which I have already mentioned, frequently prove 

 Poa trivialis — our rich moist bottoms are full of its })anicles 

 in their season — the thick and almost indistinguishable mass 

 thrown up by irrrigating a natural sole, shews more vigorous 

 panicles of Poa trivialis than of any other grass. In raw 

 grounds I have found its little spontaneous tufts stool, and 

 enlarge to a diameter of eight or nine inches, by sending
