On several previous occasions I have been permitted to place 
‘before this Society notes in elucidation of the extinct glacial 
field comprehended within the limits of the Cape Jervis Penin- 
sula. At the southern extremity of this area, more particularly, 
there occurs some very striking illustrations of Glacial Till, 
forming low coastal hills a hundred feet in height. From the 
Lighthouse situated at the Cape the cliffs of Kangaroo Island 
are clearly distinguishable across the Strait at a minimum dis- 
tance of eight miles. From the thickness of the glacial deposits 
at the Cape it appeared highly probable that they would be 
found, if searched for, on Kangaroo Island as well as on the 
mainland. 
The earliest opportunity was seized to test this point by a 
visit to the Isiand undertaken in the last week of 1898. Whilst 
pursuing the main object of my visit during the limited time at 
my disposal, I was able to make a few general observations on 
the geology of the Island, which may conveniently be included in 
the present paper. 
Eocene. 
Queenscliffe.—At Beare’s Point,a little north of the Queenscliffe 
Jetty, and fora mile to the southward of the Point, the cliffs 
consist of Eocene limestones. Near the Jetty the stone is almost 
entirely polyzoanal in composition, and in places is so loosely 
cemented that it frets away rapidly by exposure to the weather. 
About half a mile from the Jetty, on the south side, the lime- 
stone becomes stronger, and is of a bright pink colour, undis- 
tinguishable from the pink-coloured Eocene limestone of the head 
waters of the Hindmarsh River.* The limestone is quarried on 
the beach and shipped for flux. Near the Jetty the Eocene beds 
have a dip of 15° S.E., which increases in a southerly direction 
to 25° S.E., where they pass out of sight under more recent 
formations.
