SUBSOIL. forbency of the Norfolk foil ; for of a fimilar 



nature is the moft frequent fubfoil of the

REPAIRS. FEBRUARY 5. Bvttrejfts, to flay-up old 



buildings, are very aukward, very expenfive, 

 and very fubject to decay, if not well fecured 

 from the drip of the building they fupport : 

 yet, if walls lofe their upright, fomething is 

 neceffary. 



Buttrefles, however, may frequently be 

 avoided, by thickening the foundation, and 

 forming an arch-like foot or underpinning to 

 the whole part affedted. Witnefs a tall fence- 

 wall at Northreps; and a dwelling-houfe at 

 Bradfield ; where a buttrefs, in the front of a 

 good houfe, would have been very unfightly. 



1\\tfpring or width at the bale, as alfo the 

 height, Ihould be in proportion to the degree 

 and height of the bulge to be fecured. 



Where the whole wall has given way and 

 pverhangs much, a tall buttrefs may be ne- 

 ceffary ; though even in this cafe, fupporting 

 the beams and rebuilding the wall from the 



foundation
