Flowing meadows defcribed—The other kind of 
water meadows, viz. thofe ufually called “ Flowing 
© Meadows,” require much more labour and fyftem 
in their formation. The land applicable to this 
purpofe being frequently a flat morafs, the firft ob- 
ject to be confidered is, how the water is to be got off 
when once brought on; and in fuch fituations this 
can feldom be done, without throwing up the land 
in high ridges, with deep drains between them. 
A main carriage being then taken out of the river 
at a higher level, fo as to command the tops of 
thefe ridges, the water is carried by {mall trenches 
or carriages along the top of each ridge, and by 
means of moveable {tops of earth, is thrown over on 
_each fide, and received in the drains below, from 
whence it is collected into a main drain, and car- 
ried on to water other meadows, or other parts of 
the fame meadow below. One tier of thefe ridges 
being ufually watered at once, is ulually called 
“4 pitch of work;” and it is ufual to make the 
ridges thirty or forty feet wide, or, if water is abun- 
dant, perhaps fixty feet, and nine or ten poles in 
length, or longer, acggording to the ftrength and 
plenty of the water.
