Left the camp at 6 a.m. and continued the route up the river to the south till 10.10, when we halted till 2.15 p.m., and then proceeded on till 4.45, and encamped at a small pool of rainwater, the bank of the river being so steep and covered with high reeds that the water is scarcely accessible.  The valley of the river is still bounded by sandstone cliffs; but as the strata are horizontal, and the bed of the river rises, the shales are not much exposed, and the alluvial banks reach to the base of the cliffs, which are so continuous that I have not yet seen a spot where we could have ascended the tableland in which the valley is excavated.  Several tributary gullies having passed, but none worthy of special notice.  Fragments of trap-rock are frequent in the bed of the river, and one specimen contained traces of carbonate of copper; at 6.0 thermometer 92 degrees, aneroid 29.80, at the camp—­sixty feet above the river.

Latitude by meridian altitude of Achernar 15 degrees 50 minutes 30 seconds.

Valley suddenly widens.

30th November.

Resumed our route up the river at 5.40 a.m., the general course south; there being no change in the character of the country till 10.0, when the hills receded and the cliffs ceased; at 10.30 halted at a small pool in a back channel of the river.  At noon the thermometer stood at 100 degrees in the shade, and the aneroid 29.75—­forty feet above the river.  Starting again at 2.0 p.m., soon entered an extensive plain extending to the east, south, and west; followed a large creek to the south-west till 6.15, and encamped.

1st December.

At 5.40 a.m. crossed the creek and steered east to the foot of a rocky hill, but not seeing the principal branch of the Victoria, returned to the creek and then steered south-south-west till 10.0 a.m., when we crossed two small creeks, in the second of which we found a pool of water surrounded by reeds (typha), and halted during the heat of the day.  The country traversed was first a stony ridge, on which several small stone huts had been erected, but scarcely of sufficient size for a man to enter, and the roofs were only formed by a few pieces of wood and a little grass; they consist of a wall three feet high, in the form of a horseshoe, about three feet in diameter inside; the entrances of some had been closed with stones and afterwards partially opened, and I can only conjecture that, as the practice of carrying the bones of their deceased relatives prevails in this part of Australia, it is probable that these erections are used as temporary sepulchres.  After crossing this stony ridge entered a level plain of clay, much fissured by the sun, and in some parts covered with fragments of jasper and sandstones; as the creek was approached limestone prevailed, but the exposed portion seemed to be formed by a rearrangement of the broken
