The proportional value which the whole of the latter-math 
crop bears to that at the time the seed is ripe, is as 5 to 9, 
and to that at the time of flowering, proportionably as 13 
to 24. 
The above statement clearly shows that there is nearly 
three-fourths of produce greater from a clayey loam 
than from a sandy soil, and the grass from the latter is 
comparatively of less value, in proportion as 4 to 6. The 
straws produced by the sandy soil are deficient in number, 
and in every respect less than those from the clayey loam ; 
which will account for the unequal quantities of nutritive 
matter afforded by them ; but the proportional value in 
which the grass of the latter-math exceeds that of the crop 
at the time of flowering, is as 4 to 3 : a difference which 
appears extraordinary, when the quantity of flower-stalks 
which are in the grass at the time of flowering is considered. 
In the Anthoxantham odoratum the proportional difference 
between the grass of these crops is still greater, nearly as 
4 to 9 ; in the Poa pratensis they are equal ; but in all the 
latter flowering grasses experimented upon, the flowering 
straws of which resemble those of the Alopecurus pratensis , 
or Anthoxanthum odoratum , the greater proportional value 
is always, on the contrary, found in the grass of the flower- 
ing crop. Whatever the cause may be, it is evident that 
the loss sustained by taking the crops of these grasses at 
the time of flowering is considerable.
