value. The four divisions of the glacial period established by 

 Penck, supplemented by the additional two of James Geikie, were then 

 considered, but the glacial age covered neither the beginning nor the 

 end of Pleistocene time, for both were associated with mild climatic 

 conditions. 



The changes of level which occurred during the period were fully 

 discussed, especially as they affected the British Isles and more 

 particularly the Mersey district, and the remainder of the address 

 was devoted to Palaeolithic flint implements which might be regarded 

 as zonal indices, and the different culture types from Strepyan to 

 Azilian were briefly described and reference made to recent 

 investigations for the purpose of correlating the various types found 

 in this country with those occurring in the rest of Europe. The exact 

 position of the different cultures in relation to the various phases of 

 the glacial epoch is somewhat in dispute, and as regards the position 

 in the British Isles the age of the Chalky Boulder-clay is critical, as 

 the whole palaeolithic series is subsequent to this deposit, as is 

 proved by the occurrence of Chellean implements in the Biddenham 

 gravels, near Bedford, and those of the St. Acheul type at Hoxne, in 

 Suffolk.

 Annual Report for 1918-19 (adopted August 20, 1919). 



Since the presentation of the last annual report in August, 1918, 

 six ordinary meetings have been held. 



A number of exhibits have been brought and discussed by 

 members, and ten papers have been read. The titles and authors of 

 the papers are as follows : (August 21, 1918) "The post-Tertiary 

 History of the Ohau River and of the Adjacent Coastal Plain," by 

 G. L. Adkin ; (September 18, 1918) "The Geology of the Southern 

 Wairarapa District," by J. Allan Thomson ; " Further Notes on the 

 Horowhenua Coastal Plain atid the Associated Physiographic 

 Features," by G. L. Adkin; (October 16, 1918) "Tertiary Geology 

 of the Waitaki Valley between Duntroon andKurow," by G. Uttley ; 

 " The Significant Features of Reef-bordered Coasts," bv W. M. Davis ; 

 (May 21, 1919) "The Tertiary Beds of Central Otago," by P. G. 

 Morgan; " Glentunnel Coalfield, Malvern Hills, Canterbury," by 

 P. G. Morgan; (June 18, 1919) " Road-making Stones of Wellington 

 and Taranaki," by S. A. R. Mair; (July 16, 1919) " Brachiopod 

 Genera," by J. Allan Thomson ; " Some Conglomerates of East 

 Marlborough," by J. Allan Thomson. 



At the meeting held on July 16 it was resolved: " That, in the 

 opinion of the Section, the preparation of a contoured topographical 

 map of New Zealand on as large a scale as practicable (say, 1 . 125,000) 

 is now an imperative necessity, as the map is required for agricultural, 

 geological, geographical, and other purposes."
