Chap. IV. O/Dung. 20 



Surface of the Earth, whereon is the Pafture of Cat- 

 tle ; in that it cannot be inlarg'd without Addition of 

 more Surface taken from Land adjoining to it, by 

 enlarging its Bounds or Limits. 



But the artificial Pafture of Plants may be inlarg'd, 

 without any Addition of more Land, or inlarging of 

 Bounds, and this by Divifion only of the fame Earth. 



And this artificial Pafture may be increas'd in pro- 

 portion to the Divifion of the Parts of Earth, whereof 

 it is the Superficies, which Divifion may be mathe- 

 matically infinite-, for an Atom is nothing; neither 

 is there a more plain Impofiibility in Nature, than to 

 reduce Matter to nothing, by Divifion or Separation 

 of its Parts. 



A Cube of Earth of One Foot has but Six Feet 

 of Superficies. Divide this Cube into Cubical Inches, 

 and then its Superficies will be increas'd Twelve 

 times, viz, to Seventy-two Superficial Feet. Divide 

 thefe again in like Manner and Proportion ; that 

 is, Divide them into Parts that bear the fame Pro- 

 portion to the Inches, as the Inches do to the Feet, 

 and then the fame Earth, which had at firft no more 

 than Six Superficial Feet, will have Eight hundred 

 Sixty-four Superficial Feet of artificial Pafture ; and 

 fo is the Soil divifible, and this Pafture increafable 

 ad Infinitum. 



The common Methods of dividing the Soil are 

 thefe ; viz. by Dung, by Tillage , or by both (a).
