into the Triangle M N Q,^ which again di- 

 vide into half, and draw the Line Q_R. 



Thirdly. From the Point R reduce the Tra- 

 pezium D E F G into the Triangle R O P ; and 

 taking half the Bafe thereof, draw the Lin& 

 R S, and then have you divided this irregu- 

 lar Figure into two equal Parts^ by the three 

 Lines, A a> Q.R, R S. 



Fourthly. Draw the Line A R, alfo Q,T 

 parallel thereto ^ draw alfo A T, and then 

 you have turn'd two of the Lines into one* 



Fifthly, From T draw the Line T S, and 

 parallel thereto the Line R V 5 draw alfo T 

 V ^ then is your Figure divided into two e- 

 qual Parts, by the two Lines A T and TV. 



Ldjlly. Draw the Line A V, and parallel 

 thereto T W 5 draw alfo A W, which will 

 cut the Figure into two equal Parts, by a 

 ilrait Line, as was requir'd. You may, if 

 you pleafe, divide fuch a Figure all into Tri- 

 angles, and then divide each Triangle from 

 the Point where the Diviiion of the laft fell, 

 and then will your Figure be divided by a 

 crooked Line, which you may bring into a 

 ftrait one, as above. This above is a good 

 Way of dividing Lands 5 but Surveyors feU 

 dom take fo much Pains about it 5 i (hall 

 therefore (hew you how they commonly ab- 

 breviate their VYork, and is, indeed.
