446 CHRYSTALLIZED BASALTES. 



From thefe fads I am induced to believe, that if this 

 chain of hills was accurately explored, it would be found to 

 abound in its whole extent in chryftallizcd bafaltes, and in 

 this opinion I am ftill further confirmed from having ob- 

 ferved the ftrong tendency the iiohin^ as it is commonly 

 called, has to affume a regular figure on a fpur of thefe hills 

 I crofTed in going from Lancafter to Columbia.
