THE HERMIT OF PETROPOLIS. 331

 prepares its downfall, testifies to the destructive power 

 of an insidious enemy. 



It is only in the more open spots that a botanist is 

 able to make close acquaintance with the smaller 

 trees and shrubs. Near to the stream I was able to

 neighbourhood of Petropolis.
