A few miles to the westward is PORT KEATS.  TREE POINT, in latitude 13 degrees 59 minutes 20 seconds, longitude 130 degrees 34 minutes, the eastern head of the port, is surrounded by a reef, which extends from it for more than three miles.  The west side has also a reef, but of much more considerable size, stretching to the northward of Cape Hay for fifteen miles; near its extremity there is a patch of dry rocks, occupying an extent of two miles.  The channel within the heads is from two to four miles wide, and has anchorage in it between six and seven fathoms, mud.  The port gradually contracts as it approaches the narrow mouth of the inlet to a mile and a half; it then trends to the south for six miles, where it is divided into two arms, that run up for six or seven miles more to the foot of a range of wooded hills, one of which is MOUNT GOODWIN.  The western side of the inlet is occupied by a bank of clay, that dries at low water.  At about three miles within the narrow entrance on the western side, there is an inlet, and above this the anchorage is good, the bottom being of clay, in which is mixed a small ironstone pebble:  between the inlet and the narrows, the bottom is deep and rocky.

Between Cape Hay, in latitude 14 degrees 1 minute 30 seconds, and longitude 130 degrees 27 minutes 30 seconds, and POINT PEARCE, in latitude 14 degrees 28 minutes 30 seconds, longitude 130 degrees 17 minutes 15 seconds, the coast is still low, and was only seen at a distance.  Off the latter point there is a reef which does not extend to a greater distance than a mile and a half.

To the south of Point Pearce there is a very extensive opening, which bad weather and other circumstances did not allow of being examined.  It is nearly thirty miles wide, and the depth across between eight fathoms and twenty.  The south shore is lined by a considerable reef extending for seven miles from the beach.  The land was very indistinctly seen at the back, but, in one part, there was a space of more than eighteen miles, in which nothing was visible.  The strength of the tide, the bottom being sandy instead of mud, as in other parts of the neighbourhood, and the rocky overfalls on either side of the entrance bespeak this opening to be of considerable size and importance.

The shore to CAPE DOMETT was very indistinctly seen.  It occupies an extent of forty-five miles, and is fronted by extensive reefs, which project for twenty-three miles; the north extremity of the shoal water is twenty-six miles, nearly due west from Cape Pearce.  It terminates with a narrow point, and then trends in to the South-West towards the coast.

The Medusa Bank fronts the entrance of Cambridge Gulf; it projects from the coast, near Cape Domett, to the North-West for seventeen miles, and terminates with a narrow spit, thirteen miles north from Lacrosse Island, in latitude 14 degrees 30 1/2 minutes.  Both these banks are of sand, and their edges are very steep to.  They are covered with large quantities of mollusca, which are also abundant in the sea in their vicinity.
