Camp 43. Very mild night; a great many clouds; a likelihood of rain. Started on bearing of 336 degrees over a vast quantity of strong spinifex; bad travelling although not very stony. Not so much quartz today although large piles of it are to be seen. Crossed Marchant's Creek and at one mile crossed a tributary. At ten miles came to a very fine creek about 400 yards broad, in one of its branches from sixty to eighty yards; broad water completely fills the space as far as you can see southward and westward. I have called it the Williams after Edward Williams, Esquire, of the North of Adelaide. Immense holes in a light blue rock in the creek a few hundred yards north of this full of water and apparently very deep, an abundance immediately beyond in the creek, which appears to flow northward. I have come rather a short journey today as the sheep and bullocks had no time to feed yesterday. Very cloudy and sultry. Lots of small fish in this creek, none yet seen longer than three inches; amongst them are a lot of fish about the same size or a little larger, with fine vertical black stripes commencing at the shoulder and a black tip to lower part of tail--body generally lighter-coloured than the other fish. Sunday, April 27. Camp 44, Williams Creek. Mild night, not so like rain this morning. Bearing of 355 degrees crossing this creek at an acute angle, crossed this creek again at three miles, crossed again at five miles--creek close on the right; at six and one-eighth miles crossed a deep tributary at its junction--heavy timber, plenty of water. Williams Creek still close on the right full of spinifex on the slopes and short rough abrupt creeks; bad travelling; at seven and three-quarter miles commenced travelling in bed of the creek, west side, till eight and three-quarter miles, the creek bearing off more to the east. At present I keep on my course of 355 degrees, over good country the latter part of course. At thirteen miles came to and crossed a splendid creek with abundance of water and lots of fish coming from the hills west and flowing apparently east. This creek I have called the Elder after Thomas Elder, Esquire, of Adelaide. Monday, April 28.
