for upon the foil, water, and fituatlon of a pond, the 
fuccefs in the management greatly depends. The 
bed: kind of ponds ought to be iituated in a well- 
manured, fertile plain, furrounded by the fineft 
paftures and corn fields of a rich black mould, hav- 
ing either mild or foft fprings on the fpot, or a rivulet 
that runs through the plain; the water ought to be 
mild and foft, by no means too cold, or impregnated 
with acid, calcareous, felenitic, or other mineral par- 
ticles. The expofure muft be dieltered againft the 
cold blafting Eaflerly or Northern winds, by a ridge 
of hills, fituated at fome diftance from the pond, 
enjoying fully the benign influence of the fun, 
far from any thick fliady wood, that might intercept 
the beams of the fun, or where the leaves of trees 
might caufe a putrefaction, or impregnate the water 
with aflringent particles. 
Such ponds as are furrounded by poor, cold, and 
ftiff foils, are open to the Eafl and North winds, 
have a wood on one or two fides, and hard or cold 
water, or fuch as ilTues from mines, moors,, or mofles, 
are inferior in goodnefs. • . 
Ponds in a poor, dry, or fandy foil, furrounded by 
pines or firs, with the jufi-mentioned inconveniences, 
are confidered as the worflof all. 
The ground towards the pond ought to have a 
gentle fiope ; for deep vallies are fubjeCt to great 
floods, and will then endanger the dikes in a wet 
rainy feafon ; and often the expectations of many* 
years are carried away. 
The foil cannot be altered : it is therefore a chief 
qualification of a pond, to be contrived in a good 
foil.
