EOCK BY THE RIVEll S SIDE. 



July, 



precipitous face of tlie rock appears to be the same 

 kind of limestone. Immediately below the Rock, 

 for the distance of half a mile, limestone similar to 

 that of the small island occurs in gently inclined 

 beds. 



In the body of this liigh bluff the beds are 

 nearly vertical; and, as well as I could judge from 

 the view obtained in descending the stream, they 

 were disposed as if the axis of the ridge had been 

 the direction of the elevating force, the beds in- 

 clininc: towards the summit from both sides. In 

 some parts, there seemed to be inclined beds lying 

 nonconformably over the ends of the nearly ver- 

 tical ones, but I could not be certain, without 

 closer examination, that what I saw was not merely 

 oblique sections of the edges of the lower beds.
