Of the proper Choke of Soils ^ dec. 3 ? 



Juices of the Earth, and this Way many 

 Things are done, that we can by no means 

 tfftdi by Art J and this has led a great many 

 Planters into Miftakes, of which I have elfe- 

 where fpoke of. 



Secondly, Such Grounds as have the lame 

 or as good Earth as before mentioned, but 

 underneath an undivided Rock or Quarry of 

 a large Extent, thefe I fay are not proper 

 for planting Timber Trees in (whatever they 

 may be for fowing) for after the Roots of 

 the Trees have grown deeper into the Earth 

 than the Cruft or good Earth, as aforefaid, 

 and reach unto the Rock, they cannot en- 

 ter, and being only maintain'd by the up- 

 per Roots that fpread along the Surface 

 ({hallow as it is) can never grow to any 

 Bulk, not having fufficient Nourifhment for 

 all the Roots, and therefore neceflarily want 

 fo much of their due Growth 5 and altho' 

 fuch Trees may thrive 50 or 60 Years, yet, 

 as they grow in height and greatne^, fo 

 much the more are they in Danger of eve- 

 ry Wind 5 becaufe thofe Roots that fliould 

 grow deep into the Earth, not only to fup- 

 port the Tree by Nourijliment and ballance 

 it by Weight, but as ftrong Cords to bind 

 it faft unto the Earth, are altogether hin- 

 drcd and difappointed of their life by Rea- 

 fon of the Rock and Qiiarry they grow 

 upon : Alfo thofe Roots that touch the 

 Rock, for want of Entrance will, in a (hort 



time, ^^,
