and by means of reconnaissance has outlined the work remaining 

 to be done. The Cape Commission, in particular, has maintained 

 a high standard, deliberately concentrating its efforts " on the 

 scientific elucidation of the geology of the Cape province without 

 allowing itself to be drawn away into economic questions." With 

 the Director's report for 1912 are published the following papers:

8. Inter-State Conference on Artesian Water. Report of 

 Proceedings. Sydney, 1912. Pp. xvi, 68 ; 40 maps and plates. — 

 An admirable method of attacking the problem of water supply 

 for a large area is indicated by the organization of the Interstate 

 Conference of Australia. Representatives from New South 

 Wales, Queensland, West Australia, and Victoria took active 

 part in the discussions which were grouped under the following 

 heads: Definition of terms, Origin of artesian water, Outlets to 

 the Great Australian artesian basin, Delimitation of the artesian 

 basin, Hydrographic survey, Annual record of water drawn from 

 artesian basins, Collection and Classification of Rocks obtained 

 in boring, Uniform system of casing, Analyses of artesian waters, 

 Decrease in flow of artesian bores, Utilization of artesian water, 

 Corrosion of casing, Uniform legislation. 



The statistics compiled and the reports prepared as a result of 

 this conference, and published as Appendices A-Z 3 , present in 

 detail the present status of water development in Australia. 

 Among the contributions of more than local value are the 

 analyses of 450 well waters from New South Wales, by John C. 

 H. Mingaye and others, and The Artesian Water Resources of 

 Western Australia by A. Gibb Maitland, including analyses and 

 many geologic sections. A majority of the wellbores listed are 

 between 1000 and 2000 feet in depth; many are over 3000 feet 

 deep, and 22 (5 in New South Wales, 2 in the Great Australian 

 Basin and 15 in Queensland) exceed 4000 feet in depth. The 

 maximum depth noted is 5,045. 



The 40 maps, sections, and plates which constitute the second 

 volume of the report furnish an atlas of value for geologists, 

 geographers, and engineers. H. e. g.
