the Sellick's Ranges, these clays must be of immense volume. 
Some five and a half miles south of the jetty—a mile south of 
where these clays first replace the sandhills—is seen a small patch 
of Eocene polyzoal limestone at their base. This bed is never 
visibly above 20 feet in height, and is about 600 yards long in 
all It is largely worn away at the base, and owing to this its 
thinness and the weight of the overlying clays—here 80 to à 100 
feet in height —it is greatly broken about. The result is that the 
dip of the bed is hard to estimate, but seems to be five to seven 
egrees to the south. That the dip is low is shown by the fact 
that a small extension of this bed as a reef presents a nearly flat 
surface, not a series of ridges, as is the case further south. 
reaches it whenever the tide is higher than usual. The reef is, of 
course, much more indurated, or it could not exist. 
not well-shown, as, while the coast faces about west, the escarp- 
ment is irregular, sloping back from the beach, and somewhat 
overgrown ; also devoid of distinct bands. 
Up to this point the coast has run pretty consistently north 
and south, there being a slight bay from the Miocene reef south- 
wards. Here it takes a sharp turn towards the west, and 15 
henceforth very irregular. There is practically no more Miren 
the shore-line being either a reef or else piled up with detach 
boulders, with sometimes a few feet of sand interspersed „with 
rocky debris at the foot of the escarpment.
