GLACIAL DEPOSITS OF BACCHUS MARSH. 389 



111. Further, that as far as has yet been observed, these rocks 

 contain no direct evidence of glaciers having passed 

 down these valleys or over this area in Tertiary times, 

 and that there does not exist, so far as has yet been 

 observed by us, a moraine profonde to prove the exist- 

 ence of such a glacier moving down this valley from the 

 Dividing Range at any time. It will be remembered that 

 the general direction of the grooves and striae, so far as 

 observed by us, are from S.W. to N.E., or from the 

 present sea. 

 One of the writers of this paper, Mr. Geo. Sweet, speaking 

 for himself, considers the beds with which these sandstones seem 

 to him most comparable are such beds as the Hawkesbury sand- 

 stones, and it will be of great interest to ascertain if any relation- 

 ship in time exists between them and the Cape Otway sandstones, 

 whose thickness, also, as estimated by Dr. A. R. C. Selwyn, closely 

 approximates the estimated thickness of the formations under con- 

 sideration. Besides these, there are other extensive areas occupied 

 by sandstones in these colonies, whose age is as yet undetermined 

 on account of the absence of fossils ; for instance, the Grampian 

 sandstones of Victoria, and these it would be well to compare with 

 those under discussion.

IxNTRODUCTION. 



In the present pajjer an outline sketch only is attempted of the 



eruptive rocks of the county of Dundas and small portions on its 



margin. This part of Victoria has hitherto been regarded as 



deficient in mineral riches, and consequently no detailed geological 



survey of it has been undertaken. Mr. A. R. C. Selwyn visited it 



when marking out the boundaries of the principal formations in 



the colony, and his work, so far as it went, was admirable, but was
