Munster Water, on the western side, communicates with Hanover Bey by a narrow strait, with very good anchorage in Jt in four and five fathoms mud; it is, however, an incon- venient p!aee to go to, if a vessel is bound any farther up the river. Rothsay Water is a very considerable arm; and was conjectured to communicate with Prince Frederlc'.s Harbour, and, if so, would insulate the land between Capes Torrens and Wellington. We did not enter Rothsay Water; and the fides and whirlpools were too rapid and dangerous to trust our small boats without running a very great risk. At the entrance of this arm, on the south shore, there appeared to be a shoal-bank. Half-way Bay offers very good anchorage out of the strength of the tides, with abundance of room to get under weigh from. The northernmost point of the bay, SZoX?T POXST, has a small islet off it (LAJiMAS ISLZT) where the observations were taken to fix the longitude of Careening Bay. (See vol. iip. 1?$.) The two bays on the opposite, or north-east shore, are shoal, and not fit for any vessel drawing more than six or seven feet; and the shores are so lined with mangroves, as in most parts to defy all attempts at landing. After passing them, the sboros approach each other within three-quarters of a mile, but the south-west shore is fronted by a rocky shoal, which narrows it to less than half a mile; here the tide runs very strong, and forms whirlpools. On passing the point, the fryer opens into a large, spacious reach, which was called ST. Ozonoz's BAsis; and two conspicuous islands in it 'were called ST. A?mLZw and ST. PATInCa'S ISLAS?S. At the
