Having weighed the anchors (Thursday the 25th) they turned two or three miles further up the river in the afternoon, for the convenience of being nearer to the Glass-House peaks, which he now intended to visit. In the deepest parts of the river, there were from four to six fathoms water; but the channel was much divided, and narrow. They anchored near that place on the western shore where the man who had a family with him had called to them; and at this time they saw a fire, and heard several younger female voices in the same place. On the following morning Mr. Flinders took the boat up a small branch that pointed toward the peaks, but afterwards, joining the same stream, formed two low mangrove islands, leaving the Glass Houses at some distance on the left hand. About half past nine he left the boat, accompanied by two seamen and the native. Steering NW by W through a low swampy country, brought them to the side of a creek, the banks of which were low, muddy, and covered with mangroves. This creek carried them by the south west near the head of it, where the stream, passing through a rocky swamp, permitted them to wade over it. Thence they steered between N 50 degrees and 60 degrees West, getting a sight of the flat-topped peak at times, which, appearing to be considerably nearer than the highest Glass-House, was that which he first meant to visit; but observing that one of the round mounts with sloping sides was still nearer, he altered his course for it; and, after walking about nine miles from the boat, reached the top. The country through which they had passed was low, swampy, and brushy, and in the latter part of the way somewhat uneven. In those parts which were swampy, the surface was full of winding holes, where the water, lodging, rendered walking both difficult and tiresome. The places that were somewhat higher were either sandy or stony, and in these the grass tree (or gum rush) abounded; but, in general, the trees were the same as before mentioned, except that the pine was not observed to be among them. The mount was a pile of stones of all sizes, mostly loose near the surface. The decayed vegetable matter that was lodged in the cavities produced a thick covering of long, but rather spindly grass, very fit for thatch from its length. The ascent was difficult, and similar to that up Mount Direction, which stands on the east bank of the Derwent river in Van Diemen's Land. The trees upon the mount were the same as on the level ground, but taller and more straight.
