The proportional value which the grass, at the time of 
flowering, bears 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 en- 
tirely 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 affect similar soils and situations. 
Its growth after being cropped is tolerably 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 pas- 
ture on rich light soils.

The proportional value in which the grass of the 
latter-math exceeds that of the flowering crop is as 6 to 7. 
The grass of the seed-crop and that of the latter-math are 
of equal value. 
This grass is, therefore, of least value at the time the 
seed is ripe ; a loss of more than one-fourth of the value of
