Its shores are very rocky and difficult to land upon, particularly those of its northern side, which is fronted by rocks.

Off its north point there are some rocky islets, and on the north-east side a convenient landing place in a sandy bay, where boats may put ashore with great facility.

The island is covered with a pine-like tree, which is very good for fire-wood, but no fresh water was found in any part; the French were equally unsuccessful in their search.

The north-east point of Rottnest Island is in 31 degrees 59 minutes 30 seconds South, and 115 degrees 31 minutes 12 seconds East; and the variation 4 degrees 50 minutes West.
BUACHE ISLAND, according to Captain De Freycinet's account (page 170) is equally difficult to land upon; it is well wooded, but destitute of fresh water.
To the south of CAPE PERON is a long range of sandy coast, for seventy miles, to GEOGRAPHE BAY, which is open and exposed to the northward and north-west; its western head is formed by Cape Naturaliste, a rocky point, in latitude 33 degrees 27 minutes 30 seconds, and longitude 114 degrees 57 minutes 53 seconds, beyond which the coast extends to the southward, without any bays to Cape Leeuwin.

Off the cape is Naturaliste Reef, in latitude 33 degrees 12 minutes, and longitude 114 degrees 59 minutes 8 seconds; it was seen by the French expedition.
