plains between Melbourne and Station Peak. They also occur 
along the Murray, and have recently been proved, during boring 
operations in search of water, to 
exist beneath the great plains of the 
North-Western district. In Gipps- 
land they appear to underlie the low 
country near the coast from Port 
Albert to the Snowy River, though 
only exposed in a few localities, as 
at Woodside, MerrimaiPs Creek, 
Boggy Creek near Sale, the Mitchell 
River from Iguana Creek to the 
Gippsland Lakes, and on the coast 
eastward from there. (Fig. 34.) 
Many of our widespread ferruginous gravels and conglomerates 
appear to bo of Miocene age, and to be the results of littoral action 
during that period. It may, however, be taken as an established 
fact that no marine Miocene strata have been yet found in this 
colony at an elevation exceeding TOO feet above the level of the 
sea. It has been remarked that no marine Miocene beds are to 
be met with on the coast of New South Wales.
