The Constant Warfare Between the Trees and the Rocks 



Above: All rocks have 

 cracks which sooner or 

 later the rootlets of 

 some tree search out. 

 The rootlet may die 

 but it leaves a little 

 soil on which another 

 coming later may feed. 

 Then a seed is wafted 

 there and real rock 

 splitting soon begins 





Above; The lower part 

 of the trunk and the 

 root of a juniper tree on 

 a mountain side which is 

 slowly but surely split- 

 ting a great boulder. 

 The top of the tree has 

 been broken off by the 

 winds but the roots 

 keep up the struggle 



An aspen which is 

 forcing apart the rock 

 into which it is grow- 

 ing. The rock could 

 probably trace back a 

 long line of ancestors 

 of this tree each one of 

 which has carried on 

 tlie warfare relentlessly 



A portion of the roots of an up- 

 turned tree. The root system of a tree 

 is even greater than the limbs and 

 branches, equaling the spread of the tree
