Chap. X. of Gardening. 



Wall upon Joifts and Planks bedded upon the Clay^ that a 

 ■Communication may be left between the Bottom and the 

 Sides. 



The true Sign of good Clay is^ that itbeclofeand firm, 

 and not fandy^ that it draw out in Strings upon breaking, 

 and that it feem fat in handling. 'Tis no Matter whether 

 it be red or greenifh, the Colour fignifies nothing : It is 

 bought by the Cubical Fathom, which contains in all 216 

 folid Feet. The Cubical Fathom ought to have a fquare Fa- 

 thom upon every Side, which makes 3 6 Foot on the Super- 

 ficies. Clay is not dear, unlefs in the Carriage and Tranf- 

 porting of it : In fome Countries it cofts nothing but the 

 Drawing, there is luch Plenty of it in others it muft be 

 'fetched from far, which is a great Charge. 



B AS oNS of Ciment are built in a Manner very different 

 from the foregoing ; the Out-Line of the Bafon is to be ex- 

 tended, and the Diameter enlarged, but not fo confiderabiy 

 as in the Bafons of Clay i there needs no more in thefe, than 

 one Foot nine Inches of Work in the Circumference, and as 

 much at the Bottom, which is fufficient to hold the Water. 

 Thus, for a Bafon of fix Fathom Diameter, the Digging muft 

 be fix Fathom three Foot and a Iialf, and muft be hollowed 

 out one Foot nine Inches lower than the Depth you would 

 give the Bafon.
