tween them ; they are meafured every time they are 
fown, and made of equal breadth as acres, half acres, 
&c. in every furlong. Thofe lands, being in poflef- 
fion of five or fix perfons, who fow them at /o many 
different times in the fame furlong, cannot be rolled

other part of my property lies in larger pieces by the

with the common roller, if drawn by the ufual num- 
ber of horfes ; and in going down they do very great 
damage with their feet, efpecially if the corn or grafs 
feeds are fprung up above ground. | 
It is become a cuftom in the light and hilly lands 
in Wilts, Hants, and Dorfet, to plough the furrows 
fo that the horfes may go as level as poflible, in 
which cafe, as I obferved before, it cannot conveni-

for that inconvenience, | thoughta fhort one, to be 
drawn in the furrow, would anfwer well in both the 
above cafes. I ordered the one I now have to be 
made immediately, and am pleafed to be able to tell 
you it anfwered the purpofe better than I could fup- 
pofe it would; it is eafily drawn with one horfe, 
_ which, if led bya boy, and the ridges are two perch 
in breadth, it will roll the furrows of thirty acres of 
Jand in one day; the common roller, being hauled 
lengthways over all the land, leaves it as {mooth as 
if it had been croffed, Some
