of mining in this historic field, which since 1851 has yielded 

 some fifty tons of gold. 



The financial value of the industry to the State is shown 

 by the following totals, 1918; £14,419,352. Total to end of 

 1918, £300,526,555. Of this grand total the Coal Industry 

 accounts for £92,721,420, and this proportion will increase 

 with the further development of manufacturing concerns 

 and the direction of attention to the preparation of by- 

 products. 



Among the principal items of purely scientific interest 

 that have been published during the past year, and which 

 will be of direct concern to geologists of this State may be 

 mentioned: — "The completion of Dr. Walkom's series of 

 memoirs on the Lower Mesozoic Flora of Queensland," 

 published in Bulletins 367, 384, and 389 of the Queensland 

 Geological Survey. In this valuable work the author has 

 brought to modern standards the pioneer work of McCoy, 

 Morris, Peistmantel, Tenison-Woods, Etheridge, Shirley, 

 and others. He has had the opportunity, and has availed 

 himself fully of examining the large collections of the Queens- 

 land Geological Survey and those deposited in the Museum 

 of the University of Brisbane. This work is of particular 

 interest to New South Wales, in that the palaeontological 

 classification that he has adopted for the Ipswich, Walloon, 

 Bundamba, and Burrum Series, will have to be adopted as 

 a standard for the classification of our fresh water Mesozoic 

 periods. The general succession in Queensland is com- 

 parable to, though not complying with those accepted in 

 this State. As was pointed out in the Federal Handbook 

 we have in New South Wales, as evidenced by the strata 

 passed through in the Sydney Harbour Colliery Mine, a 

 direct succession from Permo-Carboniferous to Mesozoic 

 Thinnfeldia beds which must be regarded as being of 

 Triassic age. In the Sydney section we have a series of
