Tin- ('(xiaf l.nii . — OiiikumI Point (KlmI UluiY, St. Kildu). lit-s on 

 the exti'iision of tlu- vh\\Hi soutli-wcst of the KlsteiMi wiclv Crock. 

 The coast soon curves and runs neailv south, ci-ossing the JJrighton 

 vallevs at a small an^de. The ]»rojectiii^ ])oints are due to the 

 greater resistance of the lower heds of the tertiaries, and do not 

 correspond in position to the ridges. The Elsterinvick Creek 

 enters the sea through the Ehvood Swamp; there is a flattening 

 of its gradient, Imt in all the Brighton vallevs the reverse occurs. 

 There is, to put it otherwise, never I'oom for the fall to continue 

 to the sea at the same rate as the fall from 30 to 20 above sea level. 

 All of them must lie regarded as slightly encroached upon by the 

 sea. From Brighton lieach the coast runs in general nearly south- 

 east, curving out to the west at points due to the greater resistance 

 of the l)rown rocks. The attack of the sea is evidently more powi-r- 

 ful here than at Jiiighton, as is seen also in the nature of tlie 

 beach sand. At Brighton also, where the coast crosses a ridga, 

 there is a steep rise, usually back in the tea tree scrub. At Sand- 

 ringhani the cliffs rise higher and direct fi'om the beach. Towards 

 Kickett's Point there again seems to be a less rapid advance, l)ui 

 here the outcrop of the resistant roeks is much more continuous. 

 From Ehvood to this point most of the best dip observations gi'^'fc 

 a north-westerly strike in the brown rocks with low dips 10 degj-c^s 

 or less. Joints are often pronunent, and in these north-westerl, 

 strike is most conunon, though others are also frequent. 



Near Beaumaris the coast turns north-east for a mile with cou- 

 tiiuKuis cliffs to 70 feet high forming one side of Beaumaris Bav. 

 At the head of the bay is seen a comparatively steep dip in the 

 tertiaries 25 <legiees south-easterly. l{y this the* i-esistant rocks 

 are carried well below water level, and a vertical cliff in the soft 

 upper beds follows, the coast having resumed a south-easterly 

 direction. The fold is not seen all along the north-west side of the 

 bay. At the end, where the water appears deep and the beds do 

 not seem to be curving, it is possibly replaced by a fault or has 

 been crossed by the marine enci-oachment. 



The upper beds of the tertiaries are not seen on the north-west 

 side of the bay. The highest hill near reaches 1(1(1 feet, but its 

 top is wind-blown sand. As the removal of the upper l)eds d(»es 

 not seem to be connected with the subierial denudation, it was pro- 

 bably achieved by marine action during emergence. As usual, in 

 a very short distance from the coast, the valley system is (piite 

 independent of the c<iast line. 



The fold at Beaumaris Bay is no doubt a part of the structiire 

 giving rise to the Cheltenham axis, its strike passing along the east
