Sweet-scented vernal grass. Nat. of Britain. 
At the time of flowering, the produce from the space of 
an acre equal to .000091827364 of a brown sandy loam 
with manure, is

The proportional value which the grass at the time of 
flowering bears to that at the time the seed is ripe, is as 
4 to 13.

The proportional value which the grass of the latter- 
math bears to that, at the time the seed is ripe, is nearly as 
9 to 13. 
The smallness of the produce of this grass renders it 
improper for the purpose of hay ,* but its early growth,

weights not named are, quarters of drachms, and fractions of quarters of 
drachms ; thus 7.1| means 7 drachms 1 quarter of a drachm and f of a 
quarter.
