352 Dr. percival’s Account of a 
find his account in preparing it from dung-hill wa- 
ter: for it will furnifh him with a top dreffing for his 
garden and land, of great fertilizing powers. But if fuel 
be dear where he refides, and conveniences for com- 
buftion be wanting, the fimple evaporation of the water 
may fuffice, and the putrid lye, thus reduced to a folid 
form, will prove to be a rich manure. At Hart Hill, 
my fummer abode, about three miles from Manchefier, 
I have lately pratftifed a method of making a compoft of 
the dung-hill water. The weeds and rakings of the gar- 
den, the dreffings of the fields, the leaves blown from 
the trees, and other refufe matters, are put together near 
the refervoir, out of which the water is occafioally 
pumped and fcattered over the heap: fo ftrong a fer- 
ment almoft inftantly excites putrefaction. And thefe 
vegetable fubftances are foon converted into a fertile 
mould, which retaining the falts and oils of the dung- 
hill water, fuffers the fuperfluous moifture to exhale into 
the air, or to percolate through it. And I have found, 
by experience, that the compoft thus prepared is laid on 
the meadows at lefs expence, and that it is more effica- 
cious and durable in its operation than the fprinklings, 
which, at ftated times, they formerly received : for my 
land, though good and in fine condition, is light and 
I fandy,
