patches of bloodwood, leguminous ironbark, and sterculia.  The soil varied from a brown loam to ironstone gravel, and in a few spots ferruginous conglomerate was visible.  On the loamy soil the grass was good and abundant, but the gravel was covered with spiny treraphis.  This tableland was so level that no declivity could be detected during the continuance of our day’s journey, which lasted till 5.30, when we bivouacked without water; by taking the precaution of letting the horses feed on the outward track, and secreting ourselves after dark in the high grass, we passed the night without the necessity of keeping watch after midnight.

7th July.

Our horses having strayed back on the track, we carried our saddles and tracked them about two miles, and then mounting our horses steered north for some miles; but all was level forest without any sign of the existence of water, except a few cockatoos.  I then turned to the south-west; crossing the outward track, and at length came on a shallow watercourse trending west, a ridge of rocks having confined the channel to a narrow space; three small waterholes were discovered in which a little water remained; below this the creek turned south-south-east, and I again turned towards the camp; but night overtaking us in the stringybark forest, we passed to the south of the camp without observing its position.

8th July.

Having ascertained that we had passed the position of the camp, turned to the north-east and reached the camp at 11.20.  Mr. H. Gregory was somewhat recovered, but very weak from a violent attack of fever.  During my absence a small party of blacks had visited the camp and had bivouacked a short distance up the creek.

9th July.

Moved the camp to the waterholes twelve miles south-east, and in the afternoon rode down the creek with Mr. Elsey; the creek turned to the south-south-east for a mile and a half, and was lost on a level flat, from which a channel trended to the west, which was again lost in a level flat extending to the west several miles.  Heavy showers at night.

Circumcision practised.

10th July.

Accompanied by Mr. Elsey, I proceeded to reconnoitre the country to the south-east, and at 7.45 a.m. steered 130 degrees, gradually ascending the tableland, and which was openly wooded with bloodwood, box, and white-gum; acacia and sterculia occasionally appearing.  The soil was brown sandy loam with a few ridges of sandstone rock of white colour; grass had been abundant, but was now burnt off.  The small white-ant nests from two to five feet high were very numerous; at 12.40 p.m. a slight depression in the country was observed, and limestone appeared, and deep hollows were frequent.  One of these hollows which I examined was thirty yards in diameter and fifteen feet deep; in the centre was a deep cleft of fifteen feet more, which extended to the east and west under the surface with a width
