the range. The sandstone intervening between the two layers appears 
as a surface rock only near Stony Cove, as it has been mostly worn 
away, leaving the harder basalt at the surface. 
The basaltic conglomerate, where occurring, forms an irregular layer 
from one to ten feet thick, between the basalt and the sandstone. In 
some places it is piled up in hillocks and ridges twenty feet high, 
over which the basalt has spread itself, or the sandstone has been 
deposited. On the shores south of Kiama the transitions from basalt 
to conglomerate are very numerous, and in some instances, the latter 
rises in extensive beds into the basaltic chff. Figures 7 and 8 illus-

trate this statement. ‘The first was taken in the second cliff south of 
Kiama, at the entrance to a deep cavern which runs a hundred yards 
into the cliff. A thin layer of sandstone overlies the basalt, below 
which is the basaltic conglomerate. ‘The second is from the first 
point south of Kiama. Other peculiarities are represented in figures 
9 and 10. 
In figure 9, from the second cliff south of Kiama, the overlying 
basalt is connected with a dike. In figure 10, a layer of sandstone is 
overlaid by basalt and basaltic conglomerate, part of the latter being 
included between portions of the former. 
The basait and basaltic conglomerate are sometimes so closely
