6 XXXII. Dr. J. V. Daueš: 



beds owing to the warp (which has produced the divide); nor is the 

 slope yet sufficient for them to drain in the reverse direction in the 

 saine way as the greater portion of the cut-of headwaters. Thus 

 Cargoon iake probably represents portion of the headwaters of the 

 Flinders (Q.) 7 Webb's lagoon, Buchanan and Galilée mark where the 

 warp has affected the Thomson. Salvátor is a relie of the Upper 

 Warrego, and the little Injune lagoons, farther south, are, perhaps of 

 similar origin." I do not choose to quote further, examples from the 

 country farther south being dealt with in the paper. 



The results of my own investigations, as I stated them in in y 

 prelimiuary papers, catinot be looked upon as being in aecordance 

 with Mr. Taylor's opinion corteerning the origin of the lakes on the 

 Divide. I have brought positive proofs that the Thomson River drai- 

 nage is only very lately encroaching upon the outletless area in the 

 Dividing Plateau 1 ), I collected also more positive data about the ré- 

 cent capture of the now Upper Flinders River and its tributaries 

 by a Carpentaria river, which formerly were tributaries or rather 

 headrivers of the now Thomson River basin 2 ). 



I consider the Cargoon lake as I do the other lakes (Buchanan, 

 Galilée, Dünn) which I have investigated, and likewise the Webb's lake 

 and probably also the „Moocha lake" as remains of former indepen- 

 dent basins, which had no outlet on either side — neither to the 

 West, nor to the East, and of which only recently some have been 

 captured by rivers belonging to either the great inland basin or 

 to the Pacific drainage. According to the information which I gathered 

 about the Salvátor lake I incline to the same opinion and I am convinced 

 that the upper courses of all the rivers flowing now to the South- 

 west from the Desert Sandstone and Rolling Downs country in Queens- 

 land have been only lately captured by the respective Systems aud 

 ended formerly in independent outletless lowlying basins, which 

 contained more or less periodical shallow lakes. I may only quote 

 (later) from Leichhardt's and Gregory's papers, who State their obser- 

 vations on the late tertiary deposits of the Darling Downs in a very 

 clear and convincing way.
