a very crystalline appearance in parts, and interstratified with schistose 

 shaley beds. These have the same southerly dip as the conglomerates. 

 But on their strike to the east, granite and gneiss appear, and in this case, 

 as in some others, it is difficult to decide whether the change is due to 

 faulting, or to the metamorphism of the quartzites and schistose beds. 

 Granitic rocks also come in to the south.

 little limestone is seen, but following the strike of the beds to the north- 

 west, it comes in in large quantities, being tolerably pure in places, but 

 generally silicious, and containing quartzose laminae.

the rocks are some white and very felspathic grits, with the felspar
