could be equally successful in Victoria. I miglit say that it is 

 not possible for the Queensland water to come down into Victoria. 

 There happens to be a barrier of palaeozoic rocks in New South 

 Wales which seems to interfere with the flow. I was present 

 when Mr. Checci was drawing the map to which Dr. Jack referred, 

 in which he indicated by wires the success of the bores as tO' 

 which reliable information was available as to the altitude of the 

 sites. That map shows that the water would not rise to the; 

 surface- of certain portions of Victoria. The map is now in the 

 Geological Office in Victoria. With regard to the general question 

 of artesian supply, there can be no doubt that Mr. Cox has given 

 the meeting much information upon the matter, and there can 

 be no doubt it is of great value to that portion of Australia. 

 From observations that I have made in Victoria, I think it is 

 just possible that in the extreme western portion of the Colony 

 there may be sub-artesian supplies, but I do not tliink those sub- 

 artesian supplies will come from Queensland ; they will come from 

 the watershed, say of the Australian Alps. The amount of 

 rainfall over that area is very great, 60 or 70 inches a year; 

 therefore there is a very considerable amount of water discharged 

 from that area through the western portion of Victoria and 

 underneath the Tertiary beds. Dr. Jack has shown clearly that 

 there is a flow towards Central Australia on the one hand, and 

 another flow northward to the Grulf of Carpentaria. I think that 

 flow which goes southward will flow towards the Australiark 

 IJight. 



Mr. E. T. ScAMMELL. — As representing, to some extent, the 

 West Australian side of the question, I would like to press home 

 a little more a matter to which Mr. Stirling has incidentally 

 referred, and to ask whether there is any chance, according to 

 Dr. Jack, of the West Australian peoj^le finding subterranean 

 water anywhere in the direction either of the North Australian 

 Bight or further north still, and if so, I should be very glad if 

 Dr. Jack would say a word upon the matter. 



Mr. Woodford Pilkington. — I think it would add greatly to 

 the usefulness of the paper if Dr. Jack could make it so clear 

 where artesian boi'ing would be likely to be of service — in such 

 Colonies as the Cape of Good Hope, for instance — that it would 

 cause more useful attention to be paid to the subject than it now 

 obtains. People ai'e perpetually recommending artesian boring
