Barrenjoey, the south head of Broken Bay, is connected only by a low beach of sand.

NEWCASTLE.

The Beacon head of Newcastle was once an island; and the drifted sand forming the hills on which the town is built has since been thrown up by the sea.

TUGGERAH BEACH.

Brisbane Water, Tuggerah beach, and Lake Macquarie are also striking proofs of change of the same character as those at Port Jackson, especially as they occur in a country possessing no inland lakes, and along a coastline which is very even and straight in other respects.

BASS STRAIT.

The line of rocky islets extending across Bass Strait seems to be the remains of land once continuous between the two shores, probably when the current was still active in the channel of the Glenelg, and before the sea had penetrated far within the heads of Port Jackson.

ROCKS IN BASS STRAIT:
1. PYRAMID ROCK BEARING EAST DISTANT 3 MILES.
2. ROCK OF GRANITE BEARING EAST BY NORTH.
