along and continue to be exposed in the river banks with little inter- 

 ruption. A short way below the dyke, the rocks become clearly bedded, 

 and their dip may be observed, the section in descending order from thence 

 exposes 



Rough grey felspathic sandstone with many nodules of 



pyrites, beds massive, thickness obscure. 



A flag bed. 



3 feet inches Fine blue shale. 

 , Coal, A. 

 , Sandy shale. 



, Hard sandy shale, and hard flag. 

 , to 40 feet — Coarse grey felspathic sandstone with no- 



dules of pyrites, which look like a repetition of the beds 

 noted at the top of the section ; no indication of a fault, 

 by which they might be thus brought to the surface 

 again, is however noticeable. 



The dip down to this is somewhat equivocal ; but here 

 it seems to be steady, 15° to E. 5°, N. 



4 „ „ Coal— A! — includes tw T o bands of blue shale whose 



aggregate thickness is about nine inches, the coal is 

 pure, light, and bituminous. The four feet given is a 

 minimum thickness ; for the bottom of the bed is not 

 seen. On the supposition of the repetition above sug- 

 gested this coal would be the same bed as the three 

 feet six one noted already and marked A. 

 10 „ „ Flag beds, not well seen, hard and soft flags, and 

 thin sandstones, thickness somewhat uncertain. 

 The continuity of the section is here interrupted ; rocks soon again 

 appear in descending the stream, and keep on the same general direction 

 of dip. In descending order, we have, 



7 feet inches Brown and grey felspathic sandstones, dip E. 15°.
