Three hundred yards further on Eocene again appears over- 
lying the Cambrian. It is here, however, much inclined, dipping 
to the N.N.W. at an angle of 50° at first, increasing to 65°, and 
breadth. ue, however, also to the great inclination, it is 
extremely regular, and for a 150 yards or so where the cliffs take 
a bend and run approximately parallel to the direction of strike 
W.S.W.) it consists of a series of ridges, parallel to each other 
and to the shore. One ridge in particular, though only two feet 
wide, is so uniform that it was keeping the sea inside at a height 
of 15 to 18 inches higher than outside. In this the reef is very 
different to that at the small patch of Eocene rocks to the north, 
and to the reefs south of the Port Willunga Jetty and at Blanche 
oint. In these cases, where the dip of the rocks is low, the 
it to reveal the strata in horizontal bands, but, again owing to 
the high dip, every projection of a few feet causes a considerable 
depression in the position of the band on the face of the cliff, and in 
e same way every recession of a few feet causes a corresponding 
elevation. "The result is that, seeing the escarpment here alone, 
one would go away with the impression that the strata were 
highly contorted. 
These Eocene beds reach to a considerable height—at their. 
southern extremity over a hundred feet; but are not so high 
further north. 
The lithological character is considerably different from that of 
the bed before mentioned (though containing pretty much the 
same fossils), and approaches more nearly to that of the Eocene 
to the south of the Port Willunga Jettv. The rock is not nearly 
so.full of polyzoa, and yields only 60-70 per cent. soluble in acid, 
yards further, their last appearance in the cliff being at an alti- 
tude of over a 100 feet. The Eocene reef extends for perhaps a
