dered. in the Anihoxanihum odoratum the pro- 

 portional difference between the crass 61" these 

 crops is still greater, nearly as 4 to 9: in the Poa 

 pratensis they are equal; but in all the latter llow- 

 erinir grasses experimented upon, the flowering 

 straws of which resemble those of the jllopp.curus 

 pratensis, or j4nthoxanthum odoratum, the greater 

 proportional value is always, on the contrary, 

 found in the grass of the flowering crop. Whate- 

 ver the cause may be, it is evident that the loss 

 Bustamed by taking the crops of these grasses at 

 the time of flowering is considerable.

 The proportional value which the grass at the 

 time of flowering hears to that of the latter-math, 

 is as 6 to 8. The grass of the seed-crop, and that 

 of the latter-math, are of equal value. 



The downy hairs which cover the surface of 

 the leaves of this grass, when growing on poor 

 light soils, almost entirely disappear when it is 

 cultivated on a richer soil. It possesses several 

 good qualities which recommend it to particular 

 notice ; it is hardy, early, and more productive 

 than many others which aflect similar soils and 

 situations. Its growth after being cropped is tole- 

 rably rapid, although it does not attain to a great 

 length if left growing : like the Poa pratensis, it 

 sends forth flower-stalks but once in a season, and 

 it appears well calculated for permanent pasture 

 on rich light soils.
