Dec. 25.—­We returned to Brown’s Lagoons, and entered our camp just as our companions were sitting down to their Christmas dinner of suet pudding and stewed cockatoos.  The day was cloudy and sultry; we had had a heavy thunder-storm on Christmas eve.

Dec. 26.—­During the night, scud passed from the east; in the morning we had some heavy showers without wind; it cleared up at ten o’clock, and we took advantage of four hours fair weather to travel on.  We again passed the huts of the natives, and encamped about seven miles farther down the creek.  We were, however, scarcely housed, when heavy showers of rain began to fall, and rendered the soil, which was a stiff loam, heavy and boggy.

Dec. 27.—­Though we had hobbled our horses with straps and stirrup leathers, they had strayed, during the night, to the more open country, where they separated from each other in search of food; and it was not until after three hours search that Charley found the greater part of them.  We had, however, watched the bullocks during the night, and were therefore enabled to proceed; which we did as far as the fine sheet of water before mentioned, when Charley again went in search of the missing horses, with which he returned after some time.

The showers continued until about 10 o’clock last night; at 3 A. M. the sky became clear, and continued so through the morning, except an occasional cloud from the eastward.

Mr. Calvert found a Bauhinia in blossom; which was not only different from the Bauhinia found afterwards at Comet River, but also from that of the Mitchell.  Mr. Gilbert found a new species of sleeping lizard, with four lighter stripes on the dark brown ground along the back, and with dark spots on the sides.  Mr. Roper shot some ducks, and I found a species of Ancylus; besides the species of Limnaea and Paludina, which we had previously met with.

Dec. 28.—­We travelled over the Box-tree flat, until we reached the open basaltic ridges mentioned on the 23rd December, and kept along their base.  The creek, which had disappeared on the flat, here again formed a large deep channel, lined with Melaleucas.  Hollows existed along the hills, and water-holes ran in lines parallel to the creek; all now quite dry; a scrubby forest land alternated with open flats and Bricklow thickets.  Water was very scarce; and having encamped my party, I started immediately to reconnoitre the country.  I followed the creek to the northward, and found it lined by scrub; but the belt along its west side was narrow, and beyond it, a fine open undulating country was observed extending far to the south-west and west, in which direction the loom of distant ranges was seen.  These plains, which had some patches of open forest land, were, at the request of my companion, Mr. Calvert, named “Albinia Downs.”  To the north-west, the mountain with the hummock lay close before us, throwing out subordinate spurs to the westward.  In riding to the most northerly end of it, I fell in with a small water-course, which led me to a large creek coming from the south-west and west-south-west, with fine Casuarinas fringing its banks and forming a dark tortuous line amongst the light green foliage of the trees on the neighbouring flats.  About six miles lower down, it was joined by the scrub creek on which we were encamped.
