158 0/ Terrace-Walks. 



Let us come now more particularly to the 

 Profile. The Pillar being fix'd, as before di- 

 refted, we allow five Foot, or five Foot and 

 an half, for the Height of the Bafement above 

 the Terrace, and three Foot, or three Foot 

 and an half, for the Height of the Terrace 

 above the grand Plan of the Lawn or Parterre, 

 as appears by the Scheme 5 we then allow aa

 Mmre^ and other Artifts, in their Water- 

 Levels , are, upon other Occafions, content 

 with lefs.

 (except obligd by the Defcent of the Ground) 

 lefs than three Foot and an half, or four 

 Foot 5 nor ought we to make it more than fix 

 Foot. And this laft is v;hat I have obferv'd 

 in the Profile.

 Yards Diftance from the Houfe, one may take 

 the Liberty to fwerve from it 5 but it ftiould 

 be rather a rolling Level, than a ftrait ftiff 

 one, than which nothing looks more cramping 

 and ridiculous, and is a Blemifh in a great 

 Defign that might be nam*d. Where ever, in 

 that Cafe, the Ground fills ofi too quick, the
