in the three separate beds is a curious circumstance, and 

 suggests the possibility of the change of dip in portions of the 

 beds from 90ft. to 260ft. ; or the lowering of the water in the 

 tube-bore may arise from underground springs. The latter is 

 the more likely reason, as the creek known as the Waipawa- 

 mate rises from several strong springs some distance from the 

 well, and I am aware of several very large springs at a lower 

 level in the plain in the direction of Ashcott Station. The 

 water is very clear and tasteless, and is much softer than 

 the water from the Hawke's Bay wells, but is similar to the 

 Wanganui artesian water. 



The value of an artesian supply to the residents on the 

 plain cannot be estimated, and now that the question has been 

 settled the residents of Woodville may look with confidence 

 to the possibility of finding an artesian supply within the limits 

 of the borough. 



The diagram I exhibit shows the character of the deposits, 

 and gives information which will be of value to sinkers 

 should other wells be put down.

Aet. XLIX. — On the Occurrence of Granite and Gneissic 

 Rocks in the King-country.

The whole of New Zealand belongs to one great orographical 

 system which forms a line of elevation traversing the Pacific 

 Ocean in a north-east and south-west direction, with a long 

 northern prolongation stretching away to the north-west. 

 But, while parts of one system, the geology of the greater 

 islands is specialised by many important features, among 

 which stands conspicuously the absence in the North Island of 

 the ancient Palaeozoic crystalline rocks so widely and typically 

 developed in the Provincial Districts of Otago and Nelson. 

 Their absence has been the subject of many interesting dis- 

 cussions among geologists, and many curious and sometimes 

 ingenious hypotheses have been suggested as to the probable 

 conditions existing in this area in older primary times. 



The late Dr. Von Hochstetter, in his lecture on the geology 

 of the Province of Auckland, delivered to the members of the
