as compared with the left. This is well seen where the creek 

 to the west of Bayswater runs westerly and then southerly. 



At Wheeler's Hill, a prominent point on the Fern Tree Gully 

 Road, and on the western side of the Dandenong Creek, the 

 ridges on the eastern side are so low compared with this hill 

 that a fault scarp for a limited distance is here suggested again, 

 rather than the gentle tilt or dip. This, however, is not clear. 

 Wheeler's Hill appears to rise some distance above the general 

 height of the Yarra Pleateau in this locality, and this may 

 account for the apparent discrepancy. 



The Blind Creek has some flats towards its head, and al- 

 though apparently confirmative of the suggested origin of the 

 Bayswater and Scoresby Flats, they are hardly distinct enough 

 compared with the lower portion of the stream to warrant any 

 definite conclusion being drawn. This indefiniteness may be 

 due to the head waters of the creek not penetrating (accord- 

 ing to the current miaps) the Dandenong Ranges, and hence 

 not gaining that supply of water and force required to form 

 the flats. 



The Corhanwarrabul Creek seems to be a similar case to 

 that of the main upper portion of the Dandenong Creek, and 

 the wide flats at Scoresby may probably be explained in the 

 same way as the Bayswater flats. The Ferny and Monbulk 

 Creeks (affluents of the Corhanwarrahal Creek) have cut liack 

 well into the mountains, which have furnished sufficient water 

 and force to produce the flats. The Corhanwarrabul Creek 

 valley has not been observed very much, so that stress cannot 

 be laid on its apparent history. 



Once differential movement is allowed during uplift, then, in 

 addition to the more prominent features determined by such 

 uplift, minor distinctions may arise, and it is possible thai the 

 Bayswater and Scoresby Flats are due in part to this cause. 

 At the same time the explanation given above appears to 

 meet the facts without any other hypotheses. 



There is a depression beween Mitcham and Ringwood. 

 This was formerly occupied by a branch of the Dandenong 

 Creek, but as shown by Mr. Thiele (7, p. 103), its head waters 

 have been captured by tlie Mullum Mullum Creek, and diverted 

 to the Yarra.
