SOME DYNAMIC PHENOMENA. 355 



The rock, in its most altered condition being a semi - crystal- 

 line schist, and in other parts showing less change, can be con- 

 nected with its original state. Had the folding been more 

 intense, it is reasonable to suppose that the entire rock would 

 have been transformed into a completely crystalline quartz - 

 schist, showing no evidence of clastic origin, and possibly the 

 foliation throughout would have corresponded to the original 

 bedding. C. R. Van Hise.
