8 OF RAISING WOOD 



deed no appearance of earth, there is no 

 poflibility of ftirring the earth with a 

 hack ; yet we muft not deipair of railing 

 trees and (hrubs, which is evident to be 

 leen in natural woods where trees and 

 (hurbs are feemingly growing out of the 

 ftone. No art can pretend to plant in fuch 

 places ; but nature (hews us what (lie can 

 do, and by following her dictates we may 

 accomplifh what has been thought im- 

 poffible. 



IN all rocks there are openings and ca- 

 vities, and by the moifture falling from 

 the higher parts of the rock into the bou 

 torn of the openings, there is fufficient 

 nourifhment to vegetate feeds ; and when 

 they are once in a growing ilate, the 

 young roots will find cavities and open- 

 ings to pufh into, and alib nourifliment 

 fufficient to make a tree, bufh, or flirub. 

 It cannot be fo certain to get trees and 

 ftirubs to grow in rocks as in earth; but 

 it may be depended on that many will 

 grow, and to a great ilze. The only me-, 

 thod is to drop feeds into the cavities.
