ponds or lakes, or browsing upon the leaves and branches of trees 

 forming tbick brushes on the slopes of the neighbouring hüls. The 

 rise of the country. which is very generally supposed to hâve taken 

 place, was probably the cause of the disappearance of the water, and 

 of the animais becoming extinct, when its necessary supply ceased to 

 exist." 



A. C. Gregory 1 ) says in his report: (Page 2.) „The deposits of 

 older alluvium or fossil drift are restricted to the Valleys ascending 

 westerly from the main range dividing the waters flowiug to the east 

 coast from those which flow westerly to the Darling and Murray 

 Rivers. Its limits are not well defined, but it forms the banks of the 

 présent watercourses near the summit of the range, and extends down 

 them to the level plains near the banks of the Condamine River, 

 where it appears to attain a depth of more than one hundred feet, 

 as fragments of bones hâve been obtained at that depth in sinking 

 wells". 



„It may, however, be observed that, though the fossil drift is 

 only found on the western waters in Southern Queensland, there are 

 deposits rieh in bone-drift on eastern waters at Peak Downs, in the 

 Central district." 



„This alluvium is remarkably rieh in fragments of bones jf ex- 

 tinct animais, including Diprotodon Australis, Macropus titan, Thyla- 

 coleo, Phascolomys and Nototherium, etc." 



„The bones are associated with fragments of shells of Unio and 

 otber fresh water molluscs, similar to those now found in the présent 

 watercourses, but more massive in structure. Basaltic pebbles, sand, 

 and mud, the stratification of which indicates intermittent currents 

 flowing down the présent Valleys, such as now results from the 

 annual rainfall, put much greater volume." 



„Although the greater part of the bones are broken into frag- 

 ments, and show evidence of being drifted and waterworn, there are 

 sorne which prove that many animais cannot hâve been deposited be- 

 fore décomposition in the localities where their remains are now 

 found grouped together". 



„The gênerai condition under which the bones are found indi- 

 cates that what are now broad valleys and plains were originally ex- 

 tensive marshes with watercourses flowing westward into lakes, and
