will have need likewiCe of ai fmall Inftrument,. called a> 

 Protrador, fuch as is reprefented in the following Figure, 

 which is to take die Openings of Angles. The Protrador is 

 applied to^ one of the' Sides of the Angle, and; reckoning 



from its Center, the Numbec 

 of Degrees from the Bafe to- 

 the Place where the othec 

 Side of the Angle comes to 

 cut the Circumference, you: 

 mark it down upon the Pa- 

 per, and defcribe it truly up- 

 on the Ground; ia like Prow 

 portion, by opening the Semiv 

 -orcle, and fetting the Alhidade or Moveable Index on the 

 fame Number of Degrees j becaufe the Protrador is divided' 

 into as many Degrees, as the great Semi-circle made ufe of 

 for Drawing upon the Ground.
