and JGM^&^c. and from thefe four Points G H/iL, as Cen- 

 ters^ you trace the Oval in this Manner ; putting tlie Loop 

 of the Cord over the Stake extend it to the Extremity By 

 and draw the Part of the Circle to the Indefinite Lines M 

 and v^^here you are to flop. Then Hiift the Cord of the 

 fiime Length on the oppofite Side, and fix the Loop upon > 

 from whence draw the other circular Segment, with the 

 fame Caution, to flop the Track when you come to the In- 

 definite Lines N and 0, and drive fmall Spikes in the Inter- 

 fe£lions of thefe Lines, as at the four Points MP NO. Then 

 take a longer Cord, and putting the Loop over the Stake J, 

 adjuft its Length to the Point D, and trace the Arch ND M, 

 till you come to the Track and Spikes of the circular Seg- 

 ments, with which the Tracing-Point ought to fall in exad- 

 ly. Finifli the Circumference of the Oval, by ftiifting the 

 Loop of the Cord to the other Side upon the Stake i., from 

 which you defcribe, in like manner, the Arch 0 CP. Thefe 

 two Arches joining v^ath the circular Segments, entirely 

 clofethe Oval ; after which, you deface the Lines that fcrved 

 only to the Conftruftion of it, that nothing remain but the 

 bare Track of the Oval, which will be found proportion- 

 able, and like that of the Plan.

If you would draw an Oval at Pleafure, without any 

 Elan, or that you have one upon Paper, fuch as the Oval (a)^ 

 whofe Diameters are not determined by Numbers ; trace 

 upon the Ground the Line A B, which you are to termi- - 

 nate with Stakes, and take thereon a Length at Pleafure,^ 

 about a third, as from A to C Set off the fame Length 

 from the Extremity B to D, and drive two ftrong Stakes in 

 die Points C and D, which are the two Centers of the OvaL 

 Then take a Line without Loops, bring it about the Stake FIG. XX; 



and extend it double to the Extremity H, where you 

 join the two Ends by a Loop, through which you thruft a
