The proportional value in which the grass at the time 
of flowering exceeds that of the latter-math is as 8 to 11 ; 
and the latter-math stands to that at the time the seed is 
ripe in proportion as 8 to 13. 
The merits of this grass seem to demand notice; its 
nutritive powers are considerable, and its produce large 
when compared with others which affect a similar soil.
