It is much more profitablie to increase the Iruitfuhiess 

 of land by tillage than by dung ; because only a cer- 

 tain quantity of dung can oftentimes be had, the pro- 

 duce of ten acres, beiiig scarcely sufficient to dung oiie; 

 whereas the particles of the earth may be divided and 

 subdivided. The benefit that can be procured from dung 

 is therefore limited ; whereas, no boimds can be set td 

 the advantages which arise from tillage: 



Mr. Evel}', quoliug Sir Hugh Piatt, says, that if you' 

 take a certain quantity of even the mo>t barren earth 

 you can find, reduce it to a line povvder, and expose it 

 for a year to the vicissitudes and changes of the sea- 

 sons and the inlluenees of the heav -ns, it will iicqaire 

 such a generous and masculine pregrianey, within that 

 period, as to be able to receive any foreign plants from 

 the farthest Indies, and to cause all vegetables to pros- 

 per in the most exalted degree, and to bear their fruits 

 as kindly with us as they do in their natural climates,. 



We are to suppose these foreign plants to have their 

 due degrees of heat and moisture given them. To 

 what shall we ascribe this great fertility ? To the 

 great division of the particles of the earth, and the 

 multiplication of their suriaces. 



By thus pulverizing the earth, adds he, it is found 

 that soils may be so altered from their former nature, 

 as to render the harsh and most uncivil clay, obsequi- 

 ous to the husbandman, and to bring forth roots ami 

 plants, which otherwise require the lightest and hol- 

 lowcst mould. [Pennsi/l Fdyincr.
