 : following, of one Foot thick, from the Bottom of the Dig- 

 ging, to the Level of the Ground above, which you may 

 ■ build with Shards, Rubble, or Flints^ no matter which f 

 with Mortar made of the namral Earth. This Wall is cal- 

 led the Ground-Wall, becaufe it is built only to refift the 

 Preffure of the Ground about it. 



The Wall being thus built all round the Work, caufe the 

 'Clay to be brought in, which muft be thrown into the Bot- 

 tom, and made fit for working and handling, by flinging 

 Water upon it from Time to Time, and fuffering no Dirt 

 to be in it. Your Clay being prepared, let it be fpread and 

 thrown about by Shovels-full, and afterwards kneaded by 

 little and little with Mens naked Feet, or with Rammers to 

 a Foot and a half high,

 and leaving this Interval 

 for the Body of Clay C, 

 the Wall B muft be built 

 within it, which ought 

 likewife to be i8 Inches thick : And as this Wall cannot be 

 built fubftantially, if it be founded only upon the Clay, 

 there is a NccelTity of making for it a Floor with Joifts^ 

 which is done in this Manner. Take Pieces of Timber-
