The same afternoon Mr. Fitzmaurice returned, having, as we had suspected, discovered a river that carried his boat thirty miles in an east direction from the south end of McAdam Range. Towards the upper part it was scarcely half a mile wide; but for an Australian stream was remarkably free from bends, pursuing a straight course between rocky heights, with a depth varying from two to seven fathoms. Many shoals occurred towards the entrance, where in some places it was more than two miles wide. This river was named Fitzmaurice River after its discoverer; and the mouth or inlet of it, after his companion, Keys Inlet. In sounding the channel, I found that when the hill Captain Wickham and myself were first on, behind Entrance Isle, was in a line with the north end of the high land at the south side of the entrance, it formed a good lead up. In consequence we named it Leading Hill, and the end of the range alluded to, Indian Hill, from our constantly seeing smoke near it. A flat of three or four fathoms at low-water extended across the channel, with River Peak bearing between North 35 East and North 64 East. I visited Indian Hill, but failed to meet with any of the natives, although I saw their fires not far off in the hills to the south-west. It is a ridge covered with blocks of sandstone, with a few trees here and there. From its summit I had an extensive view of the low land stretching away to the northward, and forming the western side of the channel. It appeared so cut up with creeks as to form a mass of islands and mud flats, which appeared from the quantity of drift timber, to be frequently overflowed, and partially so apparently at high spring tides. The farthest high land I saw bore west about twelve miles. MEMORIAL ON INDIAN HILL.
