The First Way of Woeking.^ 



Suppose the Line BC be drawn equal to one of the 

 Sides of the Odogone which admit to be 15 Fathom and 

 4 Foot, meafure upon the Paper, with the Protraftor^ one 

 of the Angles made by the Meeting of two Sides of the 

 O^ogone, as C and which is what is called the Angle of 

 thePolygone; fet your Semi-circle upon the Ground over f ig. XYK 

 the Point 5, and make an Angle equal to that of the OSto- 

 ;gone3 which is 135 Degrees, according to thc_ following 

 Table ; make the Side B 1 1 5 Fathom and 4 Foot, which is 

 the Length of the Bafe b c in the Plan y and do the fame 

 Work from the Points DEFGH, in all which fix Stakes, 

 and trace the Sides of the Polygone from one Stake toano-^ 

 thei", which will make it regular, and like that of a upon 

 the Paper. 



The Second Way. 



If the Center of the Odogone only be determined upoii 

 the Ground, as the Stake you muft draw, upon the Plan^ 

 Lines from the Center a to all the Angles of the Polygone j 

 take the Length of one of thefe Lines, called the Radms^ 

 as aij the others being equal to it, and all fuppofed to be 

 20 Fathom 5 then meafure upon the Plan, with the Pro- 

 traftor, the Angle made by the Meeting of two of thefe 

 Lines or Radius's at the Center as ab and ac^ w^hich, ac- FiG. XYL 

 ^cording to the Table, is 45 Degrees, and is calFd the Angle 

 at the Center. Set the Semi-circle upon the Ground over * 

 the Center-Stake Aj and mark out, one after another, eight 

 Angles of 45 Degrees, and upon each Line or Radius of 

 thefe Angles, meafure from the Stake A 20 Fathom, and 

 drive Stakes there. Then draw the Lines from Stake to 

 Stake, and they form a regular Otftogone, like that of the 

 Plan.
