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 

 finally diminishing to 45°. It extends seawards for a short dis- 

 tance as a reef, but owing to the high dip it is of no great 

 breadth. Due, 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 

 Point. In these cases, where the dip of the rocks is low, the 

 reef either presents a fairly level surface or, if the rock is not 

 quite uniform, a labyrinthine outcrop, the projecting lines of 

 greatest resistance to wear turning and twisting about extremely 

 irregularly, as is so well seen in the Miocene reef at Schnapper 

 Point, south of Port Willunga Jetty. 



Opposite to these ridges the face of the cliff is peculiar ; as it 

 is approximately parallel to the line of strike, one would expect 

 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 

 the 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 Jetty. The rock is not nearly 

 so full of polyzoa, and yields only 60-70 per cent, soluble in acid, 

 the balance being partly sand, partly clay. It is also more in- 

 durated, in places being very hard. Here again fossil collecting 

 is of very little use, everything being broken, and obtainable in 

 fragments only. 



After being absent from the face of the cliff for about three- 

 quarters of a mile, the Cambrian again is seen at the foot of the 

 escarpment beneath the Eocene, which extend for about a 100 

 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
