but upon a dry, fandy, deep Gravel, there 

 is great Danger in entring upon this Work. 



But Water is fo defirable a Beauty, that if 

 One is extravagant, it ought to be in that • 

 in fuch a Cafe, thefe Works (hould be Glay'd 

 lix or eight Inchefs thick at leaft all over, and 

 great Care ought to be taken that the Clay be 

 very good 5 and becaufe 'ris an eafy matter to 

 be deceiv'd, take a Load or two, and make 

 a large Pari upon the drieft Ground you 

 can find 5 for if you make it on wet, 

 you may expeft to be deceived 5 but very 

 dry Ground will prove the beft of Clay, 

 whilft wet Ground will make bad Clay ap- 

 pear to be good. 



This done, if the Clay is not very good, 

 ( I mean free from Stones, and other Veins 

 and Mixtures of Mould ) you ought to work 

 it with a little Water, that it may mix the 

 -better 3 and after that tread it, and ram it 

 ciofe in the Place where it's us'd 5 and this 

 niuft Jikewife be done in Clay that is fo hard 

 and ftiff as not to work without it. 



There be fome who affirm, that there is no 

 need of Claying all Over, but only the Sides 3 

 and this doubtiefs may do, where-ever there 

 is any Layers of Clay or Clayey Gravel under 

 the Bottom of your Pond, which often-times 

 naturally happens, or if the Spring lies near ^ 

 biit if it be a deep, loofe Sand or Gravel, or 

 if it be towards the Brow of a Hill, or upon 

 the Groandj i doubt it ought to be Clayed all 



over
