From near the place at which the Barwon enters the lake, to 

 the south end of Kissing Point, which is the Southern termination 

 of Leopold Hill, basalt flanks the hill but does not rise much 

 above the level of the lake. It is clearly a severed portion of the 

 flow forming the plain to the south and west on the southern side 

 of the lake. At Barwon Heads, the same rock is seen to be over- 

 lain by the Dune limestone of Mount Oolite, and is referred on 

 the \ sheet to Mount Duneed. 



At the south end of Kissing Point, and overlying the basalt, 

 occurs a bed of shells consisting of large oysters and Barbatia 

 trapezia. It is about 20 feet above the lake level and is possibly 

 a native shell-mound. 



The great mass of the hill at this point is formed of a peculiar 

 sandy limestone, in which no identifiable fossils could be detected. 

 The oflicers of the Survey, in default of fossils, refer it doubtfully 

 to miocene age. In appearance it somewhat resembles a dune 

 limestone, though as we could not find a good section, we could 

 not detect any false bedding in it. A similiar rock is marked as 

 occurring at Bald Hill across the lake, but we did not visit it. 

 We could not come to any conclusion about the age of this rock, 

 but have not seen any eocene strata which resemble it closely. 



From Campbell's Point to the north-west corner of the lake, 

 gray clays constantly appear on the beach floor, and are overlain 

 by yellow earthy limestone just above water level. Apparently 

 the beds do not rise to any height on the cliffs as we saw no 

 exposure anywhere.
