238 Geology of 



on a reduced scale, Las been added to this Eeport. Mr. Doyne 

 in his second Eeport treats principally of the lower course of the 

 "Waimakariri, in respect to the tendency it has for changing its course 

 in a southerly direction, and thus endangering Christchurch ; of 

 Kaiapoi Island ; of underground streams, as well as of the formation 

 of the Canterbury plains by fluviatile action, all based upon his levels • 

 subjects to which I shall return in due time. I have already referred 

 to Mr. E. Dobson's valuable Eeport (page 174 et segru.), in which a con- 

 siderable amount of interesting information in reference to the 

 Physical Geography and Geology of the Central Chain is contained. 



The following papers also deal with the geology of Canterbury and 

 "Westland : — Mr. J. Buchanan, of the Geological Survey of New 

 Zealand, in 1866, visited the north-eastern portion of the Province, on 

 his way to the Kaikoura district, and made some observations on its 

 geological features, of which an account is to be found in his 

 Eeport on the Kaikoura district. — Geological Survey Eeports, 1866-67. 

 Besides a number of notices in publications of a general character, 

 Dr. J. Hector, E.E.S , published in the Eeports of the Geological 

 Explorations of 1870-71, " On the geological structure of the Malvern 

 Hills district " ; and in those of 1871-2, " Further Eeport on Malvern 

 Hill Coal." In the same publication for 1872-3, Captain Hutton, 

 E.G.S., gives a general Eeport " On the Geology of the north-east 

 portion of the South Island, from Cook's Straits to the Eakaia"; in 

 which, notwithstanding his short stay in the Province, a great deal of 

 information is contained. 



I do not wish to refer here to a number of papers in the " Transactions 

 of the New Zealand Institute," treating of the age and time of 

 extinction of the Dinornithidce as I shall allude to them when treating 

 of the subject which has given rise to so much controversial writing. 



It will also be observed that the Great Glacier Epoch of New 

 Zealand and the formation of the Canterbury plains have mostly been 

 selected by other scientific writers for treatment, and although I wish 

 to avoid as much as possible entering into controversies, I shall not 

 fail to review concisely some of the contents of a few of the principal 

 papers, in order to clear, in some degree, the haze which has been 

 spread by several of the writers in question. 



The following are the titles of the principal papers by other writers 

 treating of Canterbury Geology, in the " Transactions of the New 



Zealand Institute " : —
