twixt two hills, as near a flat as may be, fo as there be a fuf- 
ficient current for the water. If there be any difficulty in 
judging of fuch, take an opportunity after fome fudden rain, or 
the breaking up of a great fnow in winter, and you fhall fee 
plainly which way the ground cafts; for the water will take 
the true fall, and run accordingly. 
The condition of the place muft determine the quantity of 
gtound to be covered with water. “Ifliould propofe in all, fif- 
teen acres in three ponds, or eight acres in two, and not lefs. 
And thefe ponds fhould-be placed one above another, -fo as 
_ the point of the lower may almoft reach the head or bank of 
_ the upper; which will be very beautiful, as well as profitable, 
as will appear afterwards. 
The head or bank, which, . by flopping the water in its cur- 
rent, is to raife the water, and fo make a pond, muft be built 
with the clay and earth taken from the pan or hollow dug in 
the loweft ground above the bank; and that pan fhould be 
fhaped as half an oval, whereof the flat comes to the bank, and 
the longer diameter runs fquare from it. 
But were there not need of earth for this purpofe, it were 
better to leave the natural foil for the fith to feed upon. I 
fhall give the reafon afterwards, and confider the manner of 
- raifing and fortifying the bank particularly.
