never held a plough) to whom the machine be- 
longed, and who bought it from the good effeéts he 
faw produced by it. A clofe of old pafture land, 
containing fourteen acres, was completely under- 
drained in four hours; from the wetnefs of the 
feafon the furrows were moftly full of water, the 
ridges were caft rather high, to keep the land dry, 
which occafioned the growth of rough grafs in the 
furrows, and which rather impeded the work; the 
plough, from the rolling coulter, was put into a 
ditch that mounded the ground, (fufficiently low to 
take off any water) and drawn up the furrows to the 
higheft ground, at the depth of 15 inches: in a few 
minutes the water ran in aftream through the open-

quantities; the furrows are dry, and fo fmall is the 
upper appearance, that it feems only like a {mall

land, with an open trench nearly filled up; the 
feveral underdrains were croffed by one at the fame 
depth; along this trench a ftream to the full fize of 
the bore immediately followed, and all the under- 
drains were emptied by it, except three, which, from 
the unevennefs of the furface, were not croffed.- 
This ground was looked upon as a very dry one, 
except in wet feafons; is rich pafture land, the foil 
rather clay, with now and then a thin fealy part.
