Towards the afternoon we discovered a small inlet, being then about 30 miles from our former anchorage in Roebuck Bay. We steered directly for it, and when within half a mile of its mouth, we had, at high-water, six fathoms. From the masthead I could trace distinctly the course of this inlet, which at this state of the tide appeared to be of great extent; but the bar which locked its mouth, and over which the sea was breaking very heavily, rendered it impossible to take a boat across without evident risk, by which no real good would be obtained, as the rise and fall of the tide, eighteen feet, on this low coast, was more than sufficient to account for the imposing, though deceptive appearance of this opening. From the main-top-gallant yard I was enabled to take an almost bird's-eye view of the level country stretched apparently at my feet. The shore, like the south side of Roebuck Bay, was fringed with mangroves, while to the North-North-East lay an extensive plain, over which the water seemed, at certain seasons of the year, to flow. The country around, for miles, wore the appearance of an interminable and boundless plain, with an almost imperceptible landward elevation, and thickly wooded with stunted trees. In sailing along this part of the coast we found several inaccuracies in Captain King's chart, doubtless owing to the distant view with which he was compelled to content himself, and to the unfavourable state of the weather against which he had to contend. I was on deck nearly, indeed, the whole of the night, baffled by flying clouds in my attempts to fix our latitude by the stars: at length, however, I succeeded in ascertaining it to be 17 degrees 40 minutes South. January 23. The morning was fine, but the wind we had experienced the preceding night caused a rather heavy swell, which rendered the attempt to enter this inlet an impracticable task; however, it was tried. We found between the ship and the shore six, four, and two fathoms, but as the mouth of the inlet was filled with breakers, apparently on a bar extending out half a mile, I was fully convinced that further perseverance would only amount to waste of time and needless risk, and therefore, after taking a few angles to fix the position of the boat, we returned on board. It appeared at low-water to be nearly dry, and then only amounted to a collection of mud and sandbanks. The examination quite satisfied me that it partook of the same character as the one already spoken of as seen yesterday, and that they are alike useless. We were soon underway, and standing towards, or rather along, the shore; and as the day advanced, the wind drew more to the westward, a common occurrence, enabling us to lay along the shore, North 1/2 East. By four P.M., we were within two miles of it, in nine fathoms.
