 sand and -water, their exact thickness and dip cannot be 

 readily determined ; but the following may be taken as an 

 approximation to the truth.

Continuing along the coast, the coal measures are again 

 displayed in section between Cape Patterson and Anderson's 

 Inlet, both in the cliffs and on the beach. Opposite the 

 entrance to the Inlet, the cliffs are succeeded by a low sandy 

 flat, forming the entrance to the valley drained by the Screw 

 Creek, which runs into the inlet near its entrance ; but, 

 after crossing the creek, the coal measures again crop out to 

 the surface on the beach, and rise into low bluffs. They 

 appear to continue along the northern shore of Anderson's 

 Inlet to the Eiver Tarwin, which is probably not far from 

 their termination in this direction ; for a few miles beyond, 

 at Cape Liptrap, we find, together with large masses of 

 intrusive greenstone, the underlying formations of mountain 

 limestone and clayslate, the latter probably lying imme- 

 diately upon the granite ; which at Wilson's Promontory 

 rises through the superior strata into a bold and lofty 

 mountain range, forming the most southerly point of the 

 Australian Continent. 



Thus it appears that the coal measures extend almost 

 uninterruptedly along the coast from Griffith's Point, at the 

 east entrance of Western Port, to the River Tarwin, a 

 distance of about thirty miles. They consist of a series of 

 beds, such as in all parts of the world are associated with 

 coal, presenting, however, certain characteristic modifications 

 of their own. The upper strata consist of a hard con- 

 glomerate grit, with a thick bed of reddish brown sandstone
