can only conclude that the present distribution of the beds at 

 different elevations is the result of extensive faulting. 



In the line of section running from the river outcrop to the 

 south side of the basin there is no sign of faulting, nor could 

 such be seen if it existed, on account of the gravels which 

 cover the river-terrace and slopes of the foothills. The section 

 as it actually appears is as shown in fig. 10.

The Wharekuri Stream cuts back into the foothills parallel 

 with this line of section, some half a mile further north, 

 and in its steep banks at a point about 12 chains above the 

 bridge the beds are seen to be greatly faulted. At this place 

 there is a great vertical fault, and four small faults or disloca- 

 tions. Mr. McKay does not refer to these faults. They were 

 examined by Mr. Hamilton and the writer in March, 1903, 

 and are shown by Mr. Hamilton"' in his paper on some fossils 

 collected in the Wharekuri basin. The sketch made by 

 Mr. Hamilton is shown in fig. 11.
