On the same evening she was herself pursuing her lonely way towards the Gulf of Carpentaria, the eastern shore of which we saw on the morning of the 1st of July. In the afternoon we anchored in 3 1/4 fathoms; the north end of a very low sandy piece of coast, which we found to be in latitude 16 degrees 13 1/2 minutes South, longitude 9 degrees 10 East of Port Essington, bearing South 70 degrees East, six miles and a half. From this place the coast trended South 10 degrees West, and was fringed with mangroves; a few straggling casuarinas grew near the sandy parts, a feature which we constantly afterwards found to recur; their tall broom-like shapes form a remarkable element in the coast scenery of the Gulf. SINGULAR TIDAL PHENOMENON. A fruitless attempt was made to visit the shore, which was fronted for the distance of a mile by a bank of soft mud. We could therefore gain no information respecting the interior; but from the numerous fires, it appeared to be thickly inhabited. It was here that we first observed the singular phenomenon of the tides ebbing and flowing twelve hours. GULF OF CARPENTARIA. Next day the coast was examined for fifteen miles to the southward; its general character has already been given, which renders it unnecessary to dilate further here. North-east winds now forced us away from the land, and we did not see it again till the morning of the 3rd; when, finding as much as four fathoms within two miles and a half of a projection, we named it, in consequence, Bold Point. It is in latitude 17 degrees 0 minutes South, longitude 8 degrees 48 minutes East of Port Essington, and is rendered conspicuous by two clumps of trees. North 23 degrees West two miles from Bold Point, we observed an opening, and after anchoring the ship as near the entrance as possible, I left with the whaleboats, accompanied by Messrs. Forsyth, Fitzmaurice, and Tarrant, to examine it, early in the afternoon. The view annexed, taken by Lieutenant Gore, just after the boats had shoved off, will give the reader an excellent idea of the appearance of the south-eastern shore of the Gulf of Carpentaria, from a distance of only two miles. In this view, a gull, resting on the back of a sleeping turtle, will attract the attention of the reader.
