proceed from D. Firft meafure the Bafe into 

 three Parts, as you have been before taught, 

 by faying, If 60 give 50, what^fliall 15 give? 

 Anfwer, 12 Chains 50 Links for the iirfl:

 Anfwer, 16 Chains 66 LinksNfor the fecond 

 Man's Bafe, which fet off from E to F^ then, 

 confequently^ithe third Man's Bafe, viz. from 

 F- to C, muft be 20 Chains 84 Links. This 

 done, draw aaol^fcure Lin- from the Point 

 afljgn'd D to , tiipMpppofite Angle B; and from 

 E and F draw the Lines E H and F G paral- 

 lel to B D. Laftiy, from D draw the Lines 

 DH, D G, which (hall divide the Triangle 

 into three fuch Parts as v/as required. 



:jff,ow to divide a triangular Piece of Land-ac^ 

 .^\ £ording to any Froportion given^ by a Line 

 ^^ parallel to one of the Sides, 



. A B C is the triangular Piece of Land, (viae 

 Fig. 3. of the next Plate) containing 60 Acres, 

 ,the Bafe is 50 Chains 5 this Piece of Land is 

 to be divided between two Men, by a Line pa- 

 rallel to B C, in fuch Proportion, that one 

 have 40 Acres, the other 20. 



Firit, divide the Bafe, as has been before 

 taught, and the Point of Divifion will fail in 

 D, A D being 33 Chains 33 Links, and D G 

 16 Chains 67 Links. Secondly, find a mean 

 Proportion between A D and A C, by multi- 

 plying the whole Bafe 50 by A D 33, 33 the
