finking of the bank; for it will do fo notwithftanding the 
prefling of tumbrels, horfes, and men working upon it. 
If you projec many ftews, or other ponds to be funk right 
down about the fame time, you will have great advantage by 
the clay you take out of them, which will be much more than 
is neceflary for the bed, and that may fortify the bed, by being 
preffed down by the tumbrels on each fide of it; and fo the 
bank will be very much confirmed, and it will alfo fave break- 
ing of ground within the pond, which is a great advantage im 
the feed of the fith. 
The Dimenfions of Pond-Heads.. 
THE dimenfions of thefe banks are governed by the manner 
of the hills rifing ; for if it be quick, then, to cover a compe-~ 
tent quantity of ground, you muft raife the bank higher, and: 
confequently it muft be made ftronger, than when the ground 
rifeth flow, fo as a moderate height fhall caft the water upon 
ground enough. And of this there will be great difference ; 
for in fome places, ten feet high fhall cover as much as twenty 
feet in others. And this will be eafily difcovered by the 
water-level, ufed according to art, whereby you may flake the 
water-line upon the ground to any height; and fo you will 
fix the determinate height of the bank..
