Two miles south-east of it was another opening of more importance, almost forming a channel quite through the flat at the entrance, which extended three miles off the north-west side of Middle Point. I named this Morning Inlet, from the time at which I entered it; and after proceeding a mile in a southerly direction landed for observations, just within the mangroves that fringe the entire coast. My view of the interior was very limited: for some distance were patches of bare mud, whitened with a salt incrustation, which appeared the character of the country immediately behind the mangroves; afterwards it rose into plains, on which small gum-trees were to be seen in the distance. From Morning Inlet the coast was slightly waving and trended East 20 degrees North. At the end of twelve miles we found a little opening on the south-east side of a small point which concealed the boats from two natives, who were out on the mud flats, till we got close to them. They gazed for a moment at the strange apparition, and then made off as fast as the nature of the ground would admit; they were quite naked, and we were not a little amused to see them floundering through the soft mud. Close to the westward of this opening are two clumps of tall mangroves, the only remarkable objects on the shore of the Gulf from Disaster Inlet. There was another small inlet four miles further on; and what is remarkable for this neighbourhood, a sandy beach midway between them. EXPLORE AN OPENING. On the evening of the 28th we entered a large and promising opening,* distant twenty-one miles from Morning Inlet; its importance was made manifest by its forming a channel of two feet at low-water through the flat at the entrance, which it threw out considerably. (*Footnote. The mouth is in latitude 17 degrees 36 minutes 40 seconds South, and longitude 8 degrees 27 minutes 0 seconds East of Port Essington.) The boats proceeded up the opening at daylight on the 29th; our hopes were considerably raised by finding a depth of three and, in some places, five fathoms, and a width of about a hundred and twenty yards. The banks were, as usual, lined with mangroves; behind which, on the eastern side, retreated vast plains, with trees of some size scattered over them. They extend to the coast eastward of the entrance, which is sandy for some distance, with casuarinae, acacias, and small gums, which was not only a pleasing change from the monotonous mangrove shore, but had also its utility, serving to show the mouth of the opening from the offing.
