(1) To be guarded by officers from the encroachment 

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

 and infractions of the law by those who have. 



(-2) To be protected from injury of various kinds, as 

 for instance, from fires or other elementary damage, from 

 destruction caused by pasturing farm animals or game, 

 and from injuries caused by insects. 



(:>) In a properly conducted forest preserve there must

 trees have sprung up too thickly, in order to effect a

 way mentioned a reproduction of the trees n not prac- 

 ticable, artificial replanting, such as sowing the seed or 

 planting young trees raised in forest nurseries, has to be 

 resorted to, although this should be done as rarely as 

 possible. 



From the foregoing we perceive that the duties of the 

 authorities in charge of our State forest preserve do not

 for and protected to their full growth, but when they 

 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-
