The PraElke Part IL 



Safons^ every five or fix Years, caufe Trenches to be made 

 as deep as the Clay-Bottom, about the Walls, and in the 

 Middle of the Walk, not going too near the Bafon, or the 

 Palifade, for fear of hurting them \ and cutoff all the Roots 

 that may have reached the Bed of Clay. 



To build the Inner-Wall, you Ihould pick out good 

 Rubble-Stones, that will not fcale and come off in Flakes in 

 the Water, or elfe get Flints and Stones from the Hills, 

 which make very durable Work, but look not fo neat as 

 the Pointed Rubble. You fliould lay here and there Stones 

 that reach the whole Thicknefs of the Wall, that is to fay, 

 fuch as make the Surface on both Sides, which Workmen 

 call Making a Parpin : This ftiffens the Wall, and renders 

 it more fubftantial. The Mortar that fliould be ufed in the 

 Conftrudion of this Wall, is made of Sand tempered and 

 beat up with Lime ; the Proportion of which is one Third 

 of Lime, and two Thirds of Sand, which makes very good 

 Mortar. 



It may beasked^ perhaps, why the Inner-Wall B does 

 not goto the Bottom^as 

 theGround-Wally^ does. 

 The Reafon is this : If 

 this Wall were fet upon 

 the Ground, as the other 

 Wall is, theWater would 

 be loft, and the Work 

 behind it become ufe- 

 lefs, becaufe the Bottom 

 Bed F could not be uni- 

 ted to that of Cupon the 

 Sides, and fo the Clay 

 would not make one en- 

 tire Body, which is the 

 great Bufinefs of all, and 

 that which keeps in the 

 Water at the Corner of 

 the Wall. 'Tis for this 

 Reafon you are obliged 

 10 build and fecure this 



Wall
