of the Surface but Room to Hand on : Therefore no 

 fuch Argument, taken from Buildings, can be appli- 

 ed to Vegetables. 



This Argument of Mr. Bradley's gives no more 

 Satisfaction to the Queftion about producing of Ve- 

 getables, than a Grazier would do, being afked, how 

 many Oxen a certain Pafture-ground would maintain, 

 if he mould anfwer, by fatisfyingyou with the Num- 

 ber of Churches which might (land thereon. 



The like Anfwer, in effect, may be given to the 

 Argument in Fig. IV. of the Pales •, only he has for- 

 got to fhew, that to mound over the Hill would re- 

 quire double the Rails, or double the Hedge-wood 

 (except Stakes) as to mound the Bale-, if it did not, the 

 Hill would be yet of the more Value, becaufe thereon 

 more Surface might be fenced in at lefs Expence. 



In his Fig. II. he gives no good Reaion why the 

 Hill mould not bear twice the Number of Trees as 

 the Bafe can do •, for there is as much Room for 

 Two hundred Trees on the Hill, as for One hundred 

 on the Bafe, becaufe he allows the Surface- to be 

 double to that of the Bale. He ought to meaiure 

 the Diftances of the Trees on the Hill, by a Line 

 parallel to the Surface they grow on, as well as he 

 does the Diftances of thole below. 



And fuppofe the Row at the Bafe, together with 

 the Surface they grow on, were rais'd up, fo that it 

 fliould become parallel to half the Row on the Hill, 

 would not the Trees in the Bafe Row be twice as near 

 to one another as the Trees in the Hill Row are ? 

 And fuppole a Line had been ty'd from the Tops of 

 all the lower Trees, before the Row was fo rais'd up 

 at one End, and then, after the Situation of the 

 Row was fo alter'd, if by this Line the Trees mould 

 be pull'd from being perpendicular to the Surface they 

 grow on, and made to ftand oblique to that, and per- 

 pendicular to the Horizon, as the upper Trees are ; 

 would the Diftances of the Trees from one another be 



alter'd
