top is about one hundred and fifty feet, quite perpendicular; and it is twenty feet wide by ten feet deep, with two small peaks on the top. I have named it Chambers Pillar, in honour of James Chambers, Esquire, who, with William Finke, Esquire, has been my great supporter in all my explorations. To the north and north-east of it are numerous remarkable hills, which have a very striking effect in the landscape; they resemble nothing so much as a number of old castles in ruins; they are standing in the midst of sand hills. Proceeded, still on the same course, through the sand rises, spinifex, and low sandstone hills, at the foot of which we saw some rain water, where I camped. To the south-west are some high hills, through which I think the Finke comes. I would follow it up, but the immense quantity of sand in its bed shows that it comes from a sandy country, which I wish to avoid if I can. Wind south-east. Heavy clouds; very like rain. Saturday, 7th April, Rain Water under Sandstone Hills. Started on the same course 330 degrees, over low sand rises and spinifex, for six miles. It then became a plain of red soil, with mulga bushes, and for seven miles was as fine a grassed country as any one would wish to look at; it could be cut with a scythe. Dip of the country to the east, sand hills to the west; afterwards it became alternate sand hills and grassy plains, mulga, mallee, and black oak. From the top of one of the sand hills, I can see a range which our line will cut; I shall make to the foot of that to-night, and I expect I shall find a creek with water there. Proceeded through another long plain sloping towards the creek, and covered with grass. At about one mile from the creek we again met with sand hills and spinifex, which continued to it. Arrived and camped; found water. It is very broad, with a sandy bottom, which will not retain water long; beautiful grass on both banks. Wind east, and cool. Sunday, 8th April, The Hugh Gum Creek. I have named this creek the Hugh, and the range James Range. It is scrubby on this side and is not flat-topped as all the others have been, which indicates a change of country. On the other side the bearing is nearly east and west. Examined the creek, but cannot find sufficient water to depend upon for any length of time; the gum-trees are large. Numerous parrots, black cockatoos, and other birds. Wind east; very cold during the night.
