v. — The Nandhewar Mountains. 



This group, which I also had occasion to visit, resembles that of 

 the Warrumbungles very closely. Here, too we meet with power- 

 ful evidences of arid erosion. Alluvial fans, mesas of Trias-Jura 

 sandstone, and the perpendicular cliffs lining the mountain 

 creeks are features as common here as in the Warrumbungles. 

 The Nandhewar group, cannot, however, be classed as a 

 conoplain. 



Conclusion. 



The definite knowledge that the peneplain and conoplain of the 

 Warrumbungle Mountain District have been carved by arid 

 agencies, raises the question whether some of the other elevated 

 peneplains of the State have not been formed in the same way.
