Foot and a half deep, if you defign it one Foot deep in 



Water. 



You allow a Foot Thicknefs to the Side- Wail Fig. 4. 

 that it may better refift the 

 Earth, tho' you give but 

 half a Foot Thicknefs to the 

 Area, or Bottom. Thefe 

 Walls fhould be built with 

 Rubble laid in Mortar, all 

 of Plaifter, becaufe Lime 

 eats the Lead, and upon the 

 Walls and Bottom you 

 faften the Sheets of Lead CC, which fliould be feamed one 

 to another with Solder. 



When you make a Bafon upon loofe Earth, or that 

 which is lately brought in, the Ground-Wall Ihould be fup- 

 ported^ at every fix Foot^ with Buttreffes, or Spurs of Ma- 

 fonry i the Foot of whidi fhmild be as broad at Bottom as 

 the Buttrefs is high, ay you fee in this Fig. Without 

 this Precaution, 'tis to be feared, 

 the Bafon may be entirely thrown 

 down. If the Bottom be not 

 good, you muft drive Piles, and 

 make ufe of Planks and Net- 

 works of Timber, to lay the Plat- 

 form of the Bafon upon. 



You muft obferve, in making* 

 the Floor of the Bafon, there 

 fliould be left a fmall Fall, or 

 Slope, to ofie fide, for a Current 

 to carry off the Water from all 

 Parts, to empty the Bafon entire- 

 ly, and to cleanfe it when you pleafe, which is done by 

 means of a Walher^ and a Wafte-Pipe at the Bottom 

 of it. 



A s to the Upper-Edge, and Superficies of a Bafon, it 

 fhould be kept very level, that the Water may cover all the 

 Walls equally, and that it may always keep full ^ which is 

 the great Beauty of a Piece of Water, and of great impor-
