material. Robin Hill, near Corea Creek, with its flat top, may be 

 cited as characteristic of this class. 



(iii.) Around Casterton, Coleraine, and Merino, we find Ijeauti- 

 fully undulating, well-grassed country, the low rounded hills bear- 

 ing witness to the evenness and softness of the level-bedded Jurassic 

 mudstones in which the streams have done their work. In places 

 where the slopes are steeper, landslips are characteristic features; 

 their abundance is probably due to the " greasy " nature of these 

 felspathic mudstones, combined with their porosity. On a small 

 scale interesting complications in the drainage of these hills have 

 been caused by the landslips. The general fertile appearance of 

 this part of the country greatly impressed Mitchell, and on his 

 suggestion the Hentys in 1837, brought stock up from, Portland, 

 settling in the neighbourhood of the present township of Henty. 

 In his pamphlet on " The First Settlers in Victoria," Henry Henty 

 says of this venture: "When they caught sight of the country, 

 ' Why, here is Sussex !' they exclaimed, ' Sussex without a building, 

 Sussex without inhabitants, Sussex all our own.' They galloped 

 their horses for joy, cheering and throwing up their hats." 



(iv.) In area A, long low ridges, generally trending north-west, 

 run away into South Australia. In these limestone often plays a 

 large part, and caves are frequent. 



(v.) Granite hills occur rarely. Bracken Hill is an example. Most 

 of these hills are residuals, the ancient, resistant bed-rock (granites, 

 gneisses, slates, etc.), having been deeply dissected in places by the 

 Glenelg and its tributaries; other hills of this class are very ancient 

 physiogra2:)hic features, relics of a prior peneplanation, covered by 

 lake and marine deposits, and more recently uncovered by stream 

 action. The Hummocks, near Bracken Hill, will be dealt with more 

 fully at a later stage. Volcanic hills, e.g., Mount Bainbrigge and 

 Mount Eckersley, occur, mostly in the south-east. 



v.— Valleys and Streams. 



(a) Glenelg River. — The valley of the Glenelg lies almost wholly 

 in those rocks of coastal plain origin, which are uniformly coloured 

 sage-green on our geological maps. Accepting all these beds as of 

 one age, and as Pliocene, Ave see that the development of the 

 river must be still more recent, and we thus have a freedom from 

 any effects of complicatory prior drainage-systems, such as must 

 be considered in dealing with most other Victorian rivers.
