Introductory Remarks. — Having in the former part of this 

 paper carried a description of the geology of the district down 

 to the beginning of the Drift period, I will now endeavour to 

 occupy your attention with a description of the older rocks. 

 Following the same plan, I shall in the first place treat of the 

 Miocenes or Upland Tertiaries ; afterwards the Fundamental 

 Eocks, and conclude with a short outline of the economic 

 geology and of the soils of the various rocks. 



Form of the Ground Occupied by the Older Strata. — A glance 

 at the map and longitudinal section will show that the 

 quartzite series on the east and west occupy high ground, and 

 enclose a longitudinal depression north and south constituted 

 of clay-slate and thin limestones, which have yielded to a 

 larger degree to atmospheric and aqueous action than the 

 quartzites have done. It will further be seen that the direction 

 of the channels of Tenafeat Creek and the South Para Fiver, 

 after receiving the water of that tributary, have been deter- 

 mined pretty much, if not wholly, by the trend and northly 

 termination of the Muuno Para quartzites. Though the
