14 FOREST PLAKTING. 



(1) To be guarded by officers from the encroacliment 

 of persons wbo have no right in them, and from abuses

 for instance, from fires or other elementary damage, from 

 destruction caused by pasturing farm animals or game,

 resorted to, although this should be done as rarely as 

 possible.

 have been cut down and others started in their places. 



If our forest preserve were conducted in some such 

 way we should not any longer be compelled to witness 

 every year the dying away of the enormous masses of 

 trees and going to rot, killing young saplings and pre-
