foil itfelf refembles, as deep as I could penetrate with 
a long knife, (viz. eight inches) an old mufhroom 
bed; and the noted grafs, fo much talked of, con- 
fifts of four forts; and is not a peculiar grafs, as ge- 
nerally fuppofed. 
The four predominant grafles, above alluded to, 
are as follow:—Firlt, of this, which is the princi- 
pal; and 2dly, of Mote-Fefcue; 3dly, Common Couch, 
whofe root thrives prodigioufly in this loofe rich foil, 
and which, perhaps, is the caufe of its fattening 
hogs, which no other field has the property of do- 
ing; and gthly, of -Agroftis Paluftris—Thefe four 
different grafles blow in four different months, which 
I take to be the reafon of every author defcribing a 
different grafs, for he who goes in May finds this 
Poa in bloom; he in June, Flote-Fefcue; hein July, 
Couch-Grafs; he who goes at Michaelmas finds 
Agroftis Paluftris. 
This ground being overrun by ftreams of water 
from the ftreet, farm-yards, &c, upon every down- 
fall of rain, it is rendered fo prolific as to bear four 
crops a year; and by the courfe of the water the 
grafs is kept couchant, and in that fpongy foil ftrikes 
at the joints, fo that it will creep a vaft length fome 
wet years. This laft May (1789) being very dry, 
it did not begin to creep before my vifit; thefe being 
the beft fpecimens Mr. Hooper and I could find; 
but eight years ago I procured fpecimens, fix and 
eight feet in length, of Poa Trivialis.
