 and Sciences. 



At prefent let us obferve, that a Hill thus 

 regularly cut out, makes a kind of natural Per- 

 fpedive from the very Lines of the Plan: 

 And, indeed, there is no Figure in all the- 

 Mathematicks, that fuits the natural Beauty 

 of an Hill fo well, efpecially when it is a 

 round one 5 but were it to be a Hill in Length, 

 one would certainly, by cutting an Hollow in 

 the Middle, make thofe Baftions at each Angle 

 of an Houfe, or any other Plan, at the Top 

 of an Hill 5 for there feems to be foraething 

 of a pleafing Air in the Breaking forward of 

 thofe Angles, fuch, indeed, as few or no Geo- 

 metrical Figures will allow of, becaufe they 

 fplay off, according to the Rules of Fortifica- 

 tion. 



Tis true, the Curtain or Flank Line, be- 

 tween the two Angles of the Hill or the Ba- 

 ftions, is longer than is allow'd in Fortifica- 

 tion 5 but that is not much to our Purpofe. 

 The Breaks of the Angles (be their Diftance 

 what they will) the Exadlnefs of the Slopes, 

 as they lye one under another, and the gene- 

 ral View of all is what, in this Cafe, is more 

 to be preferred, than any exad: Rules in the 

 military Science, (ince 'tis not Ufe but Beauty 

 that we ftrive here for. 



Our Defign being thus fix d and refolv'd up- 

 on as to the Plan, and the middle Line being 

 divided, as is before direfted, you are to turn 

 your Level length-ways of the Hill, at right 



Angles,
