Inches thick, and fix Inches broad, and bury them level with 

 the Clay at every four Foot Diftance, fo that they may a lit- 

 tle exceed the Surface of the Wall on both Sides : Thefe are 

 called RiJc/«iiz/M by xht French, and do the Office of Joifts,, 

 as D, Fig. 2. after which, lay upon them long Pieces of 

 Ship- Plank, which iliould be as broad as the Wall, and nail 

 <)r fpike them down to the Joifts j and this is what we call 

 the Platform or Floor, Fig. 2. This Work being done^ 

 you fet upon it the firft Courfe of the Inner-Wall which 

 muft be raifed as high as the other, and 18 Inches in Thick- 

 nefs at leaft i for in Bafons that are pretty large and deep,, 

 where there is a great Weight of Wattr, you muft make 

 the Wall two Foot thick, which is a means to preferve the 

 Bafon, as well as the Wall itfelf. 



You fhould not raife the Inner-Wall above half its Height 

 at firft, as fuppofe it otight to have fix Foot, you Ihould raife 

 it but three Foot 5 becaufe it would be very difficult to throw 

 in and tread the Clay to the Bottom of the Bed, if the Wall 

 be raifed its whole Height at once. The Space C, Fig. 1. 

 contained between the two Walls, called, by the French, h 

 Corroi, muft be filled with Clay to the Top of the Wall, 

 which fliould be built level with the other ; and the fame 

 Kneading and Treading muft be continued, till the Body of 

 Clay C be raifed eaven with the Ground. 



F o R working the Bottom F, Fig. 2. you are to fill the 

 whole Extent of the Work with Clay, to make a Bed of 

 18 Inches Thicknefs, beginning to knead it with that you 

 firft fpread within the Inner-Wall and Joifts 5 and uniting,- , 

 that and the Bottom together, which Ihould be cover'd with- 

 Gravel five or fix Inches deep, as you fee in G, Fig. 

 which will preferve the Clay, and hinder the Fifli from dig» 

 ging. Inftead of graveling it, you may pave the Bottom |, 

 but this is vaftiy chargeable. 



I F the Bafon be in a Wood, or near any great Trees, the- 

 Ground-Wall muft be built with Mortar made of Lime and. 

 Sand, to flop tlie Roots of the Trees, which coveting the 

 Frellmefs of theClay to nourifli them, and gathering more- 

 and more Strength, in the end overturn the Walls imo riie-
