(*Footnote. Which placed Point Brierly in latitude 37 degrees 6 minutes 40 seconds South, longitude 1 degree 18 minutes 18 seconds west of Sydney; or 149 degrees 57 minutes 42 seconds east of Greenwich, according to what I consider the meridian of Sydney.) The error I found in the position of Twofold Bay induced me to commence our survey there, for the purpose of ascertaining the position of Cape Howe," which I discovered to be rather more out in longitude; while the islet, instead of lying off it, lies four miles to the south-west. (*Footnote. This Cape, in latitude 38 degrees 31 minutes 00 seconds South and longitude 1 degree 14 minutes 15 seconds West of Sydney, although rather low, is of bold approach, and admirably situated for a lighthouse. Others erected on Montague Island and Point Perpendicular, would light the whole coast as far as Sydney.) FLINDERS ISLAND. Leaving, we again spent several days under a close-reefed main-topsail and a reefed fore-sail; but at length reached an anchorage on the eastern shore of Flinders Island within the north-east side of a granitic lump called Babel Islet. The flood tide came from the north-east at this anchorage, which can only be used in easterly winds. There is a curious dome on the inner side of Babel, which is connected by a sandy spit with the large island. Within the eastern point of the latter are the remarkable pyramidal hills, called the Patriarchs, rising out of a scrubby plain, much cut up with lagoons, which forms the character of this side of Flinders. We were enabled to fix the eastern shore of the island, from Babel Islet and the outer Patriarch, whence the view was commanding. A range of bare-topped hills lies to the west, whilst to the south-west, through a mass of clouds, we occasionally caught glimpses of some high peaks, which I named after my friend Count Strzelecki. A heathy valley stretches across the island to the westward, through which I saw the sea on the opposite side; on the northern part the hills are more rounded and lower. TO KENT GROUP. From Babel Islet we proceeded towards Kent Group, passing, in 11 or 12 fathoms, along the eastern shore of Flinders Island, where we discovered a dangerous sandy spit extending five miles off; from its extreme the eastern part of the outer Sister bore North 64 degrees West, six miles and a half. After rounding the latter the wind changed in a violent squall to the westward, and gave us a long beat of a day to reach Kent Group, during which we discovered a reef,* just awash at high-water, and bearing East 8 degrees South, five miles and a half from Wright's Rock.** (*Footnote. Beagle's Reef.) (**Footnote. A pyramidal lump, three hundred feet high, resembling a cutter under sail.)
