 then thofe opens may be filled up, but not till then.

 wall is kept perpendicular, or rather inclining a little 

 from the perpendicular towards the centre, as formerly 

 remarked in the Louth fence. "Workmen mould be

 the perpendicular, no material accident would take 

 place -, I know, however, from experience, that, in the 

 hardeft and firmed foil, this praftice cannot be de- 

 pended upon ; fo that the gauge and plummet muft be 

 always attended to. 



So much for funk fences in point of ornament ; or

In the inclined plane, this fence differs fomewhat
