without as much pains and induftry as made it. 
By this proportion, pond heads of any dimenfion may be 
projected; the matter is not fo nicely circumftanced, that a. 
little more or lefs fhould fignify. But it muft be noted, that to 
make them too flight, is the greateft error, and moft to be 
avoided ; let them be rather made too ftrong, for then you have 
not only amore fecure bank, but a more beautiful walk, and 
more room for wheel-carriage, befides a capacity of fome wood; 
all which compenfate the charge of what is fuperfluous.

IF the bank be well made, and in, fufficient dimenfion, nothing 
_can hurt it, but great land-floods, or water-fhots, which, if 
fuffered to run over the bank, will carry away the fifh, which

but alfo gurry holes in the back of the bank, and weaken it fo
