After leaving the inlet we pushed on through the scrub to a high bluff of granitic formation, distant about sixteen miles N. 35 degrees W., and named by me Mount Hall. [Note 18: After G. Hall, Esq. the Governor's Private Secretary.] The road being very heavy, it was late when we arrived there, and both our horses and sheep were much fatigued. We got a little water from holes in the sheets of granite, and had very good grass in an opening under the hill. From the summit of Mount Hall the view was extensive, and I obtained many angles. The surrounding country was low, level, and barren, and densely covered with scrub, among which, to the north-west were seen many salt-water lakes. At intervals a few elevations were seen amidst this low waste, apparently similar to the hill we were upon, among them were one or two very distant at a little N. of E., and nearer, one at E. 16 degrees N.; the latter I named Mount Cooper. [Note 19: After Charles Cooper, Esq. the Judge of the colony.] At a bearing of S. 35 degrees W. another saltwater inlet was seen apparently communicating with the sea; but this we could not satisfactorily ascertain from its great distance. The latitude of Mount Hall, deduced from observations of a Lyrae and a Aquilae, was 33 degrees 2 minutes 40 seconds S. Several native fires were seen to the east and south-east in the scrub. November 3.--After seeing the party ready tomove on, I left Mr. Scott to conduct the dray, whilst I rode forward in advance to the depot near Streaky Bay, where I arrived early in the afternoon, and was delighted to find the party all well, and everything going on prosperously. They had expected me some time before and were looking out very anxiously for my arrival. The WATERWITCH had arrived on the 29th of October, but the master did not communicate with my party before the 31st; so that until the last three days they had been quite ignorant of our movements, and uneasy at our so greatly exceeding the time originally fixed for rejoining them. Having sent back a man, and two fresh and strong horses to assist the dray, I reconnoitred once more our depot of 1839. Situated in the middle of some extensive grassy openings among the scrub, is a solid sheet of limestone of a very hard texture: in the centre of this rock is a small oblong opening, a foot deep and only just large enough to admit of a pint pot being dipped in it. This curious little hole contained water from five to seven inches in depth, the level of which was maintained as rapidly as a person could bale it out; this was our sole supply for ourselves and horses, but it was a never-failing one.
