 lirft 2p or 30 years, and at the fame time tend to 

 rear and nurfe up the oaks intended for the future 

 grove, we mud confider our plantation as only then 

 commencing its career, and charge it with no ex- 

 penccs till that period arrives. We (hall then find, 

 that if the mind balanced upon the fubjefl, under 

 the head of the laft confideration, the prefent one 

 will preponderate the fcale in favour of our dodtrine: 

 and this reafoning applies to no other trees we have 

 mentioned, for poplars will not thrive on fuch foils ; 

 —the drip of allies is allowed to be injurious, and 

 thefe, as well as the abcles, would overtop and Ipoil 

 the firsi not to add, that as all thefe derive their 

 nourifliment from lateral roots, they would impede 

 if not prevent the growth of firs; whilfl in oaks, 

 experience fhews that their fupply is derived from 

 a deeper foil, or they are furnilhed with different 

 particles of nutrition j there fcems too fomething 

 congenial in their nature, and in their configuration 

 there is an adapdon to each other. 



When I confider all the circumftances, I am in- 

 clined to draw this conclufion, that if a regifter for 

 100 to 150 years could be procured, of ground 

 applied to the growth of oak timber, and the like 

 quantity applied to the growth of any other kind> 

 the former would prove at leaft equally produdtivc
