sh, small-grained limestone.
The strata, in general, dip slightly to the N.E., and form
gently-swelling grounds, which at the distance of about fifteen miles to
the southward terminate in hills, named the Melville Range. These hills
are apparently connected with those which skirt the coast to the
westward of Parry's Peninsula, have rather a soft outline, and do not
appear to attain an altitude of more than seven or eight hundred feet
above the sea. Ridges of naked trap-rocks, which traverse the lower
country betwixt the Melville hills and the extremity of the Cape, rise
abruptly to the height of one hundred or one hundred and fifty feet, and
have, in general, an E.N.E. direction. When these trap ridges reach the
coast, they form precipices which frequently have a columnar structure,
and the nearly horizontal strata of slate-clay are generally seen
underlying the precipices. In many places the softer clay strata are
worn considerably away, and the columns of greenstone hang over the
beach. Columns of this description occur at the north-eastern extremity
of the Cape, and the slate-clay is not altered at its point of contact
with the greenstone. The soil in this neighbourhood is clayey, and some
small streams have pretty lofty and steep clayey banks; the shaly strata
appearing only at their base. A better sward of grasses and carices
exists at Cape Lyon, than is usual on those shores. Many boulders of
greenstone and large fragments of red sandstone strew the beach.

At Point Pearce, four or five miles to the eastward of Cape Lyon, a
reddish, small-grained limestone forms perpendicular cliffs two hundred
feet high, in which a remarkable cavern occurs. Near these cliffs the
slate-clay and reddish limestone are interstratified, and form a bold
rocky point, in which the strata dip to the N.E. at an angle of 20
degrees. The coast line becomes lower to the eastward, and at Point
Keats a fine-grained, flesh-coloured sandstone occurs. This sandstone is
quartzose, does not possess much tenacity, and is without any apparent
basis.

At Point Deas Thompson the limestone re-appears, having reddish-brown
and flesh-red colours, and a splintery fracture. There are some
beautiful Gothic arches formed in the cliffs there by the weathering of
the strata.

Five miles farther along the coast, near Roscoe River, the same kind of
limestone forms cliffs twenty-five feet high, and is covered by thin
layers of soft slate-clay. On the top of thes
