140 ANNUAL MEETINGS 



and smelting. Another party at the same time 

 visited the Sturt River to see the Cambrian glacial 

 beds, and explored the Permo-Carboniferous glacial 

 beds and the archaeocyathine limestones of Hallett's 

 Cove and finally the granitic rocks in the neighbour- 

 hood of Victor Harbour. From Melbourne the 

 geologists went to Macedon to examine the alkaline 

 igneous rocks and to Bacchus Marsh for the Permo- 

 Carboniferous glacial tillites lying upon striated 

 surfaces of older rocks. From Sydney there were 

 excursions of both geological and biological interest 

 to the Blue Mountains, which afforded the geologists 

 an opportunity of studying the leading features of 

 the geological structure of New South Wales and the 

 remarkable elevation which this, in common with 

 many other parts of the continent, experienced in 

 late Tertiary or post-Tertiary times. An examination 

 was also made of the Jenolan Caves, which are typical 

 examples of stalactitic caves in limestone of Silurian 

 age, one of the interesting features of which was the 

 remains of an aboriginal skeleton embedded in the 

 stalagmitic floor. The excursions to West Maitland 

 and Newcastle gave an opportunity of examining 

 the productive coal measures of the State. At 

 Brisbane two of the most notable excursions arranged 

 for geologists were those to the Glass House Moun- 

 tains, a series of trachytic volcanic necks rising 

 abruptly from the plain, and to Ipswich to examine 

 the Trias- Jura coal measures and associated volcanic 

 rocks. Some of the most noteworthy points that 

 impressed the geologists from Europe were the 

 remarkable extent on the Australian continent of 

 Permo-Carboniferous glaciation, the evidence of 

 comparatively recent extensive elevation, the well- 

 preserved planes of erosion at different geological
