But the most remarkable feature in the scene was an isolated flat-topped hill, having all the appearance of a bastion or fortress, rising abruptly from the surrounding plain, to an elevation of 650 feet, the upper part being a line of cliffs, greatly adds to the appearance it presents, that of a complete fortification. It bore North 85 degrees East, fourteen miles from Fossil Head; and the country between was very low, and intersected by a creek about midway. This remarkable piece of land is called in the chart Table Hill; an inlet trended in towards the foot of it. We noticed several old traces of natives; the country in the neighbourhood was of a stony desolate character, yet appeared to afford nourishment for a small growth of white gums. After examining two mangrove creeks of no importance, in the north-west corner of the bay fronting the ship, we returned. Our hopes of finding a river of some magnitude were not in the least destroyed from what we had seen from Fossil Head, and the southerly direction of the flood-stream fostered our belief. Independent of these signs, we felt that we were again entering upon a new part of the continent, and the thoughts thus engendered acted like a powerful stimulant, so that we were not easily cast down. The tide serving badly, and the day being far advanced, it was decided that we should not move the ship till next morning, when after getting abreast of Fossil Head, we steered from it on the bearing of the deep-water channel we had seen yesterday. We proceeded cautiously, feeling our way with the boats ahead. After passing some distance along the eastern side of a long dry sandbank, we were obliged again to anchor, both boats signalizing a depth of only two fathoms. FIND A CHANNEL FOR THE SHIP. Table Hill bore North 46 degrees East, fifteen miles, and Fossil Head North 15 degrees West. It was now necessary to find a channel for the ship, which I succeeded in doing the next day, and on that following, the 12th, Captain Wickham, Mr. Bynoe, and myself, went to visit the high table range, while Messrs. Fitzmaurice and Keys were to examine the large inlet running in towards the foot of Table Hill. By following a creek we almost reached the foot of the high level range in the boat; a line of cliffs stretched along near the summit, beneath which it sloped down rapidly to the plain. We ascended by a slight valley, communicating with a break in the cliffs, but found on reaching the top that instead of being on a level, we were standing amidst a series of undulations or low hills, forming the crest of a platform, but so blended together, and of so nearly the same height as to appear in the distance one continuous plain. It was, therefore, with some difficulty that we could find the highest part, each, until we reached it, appearing to be so. Ultimately I was compelled to climb a tree, in order to obtain the necessary angles. VIEW FROM TABLE HILL.
