Art. VI. — Note on the Geology of tlie Mary River, Queensland. By 

 Rev. W. B. Clarke, M.A., F.G.S. 



[Read 6th November, 1867.] 

 On the 4th of last September, I read before the Society a paper 

 on the Auriferous prospects of Queensland. In that paper were 

 enumerated certain localities (along a linear range of 900 miles) 

 in which Gold was known to me to exist, or in which I anticipated 

 it would be found. 



At the extremities of this line were the country between the 

 Mary River and Brisbane to the S.E., and that between the Clon- 

 curry and the Albert to the N.W. 



Since September both these extreme portions of the area dis- 

 cussed have been brought into public notice as producing Gold — 

 Mr. Landsborough having reported Gold found at the head of the 

 Leichhardt River, west of the Cloncurry ; and a gold-field being 

 now beginning to be worked at Gympie Creek, about fifty-five 

 miles above Maryborough, on the right bank of the Mary River. 



The latter locality will probably attract more adventurers than 

 the former, and some persons may naturally inquire as to the 

 structure of the country. 



It may, therefore, be useful to state that the Auriferous region 

 in that part of Queensland appears to be considerable, inasmuch
