Sunday, 18th May, King's Chain of Ponds. In the afternoon the sky became cloudy, and at sundown was quite overcast; the day exceedingly hot, and the wind nearly calm. The clouds came from the north-west, and the little wind there is from the south-east. Monday, 19th May, King's Chain of Ponds. As the sky is overcast with clouds, so that I cannot see the sun, and as it is nearly impossible to keep a straight course in such thick country without it, I shall remain here to-day, and if it should break up I shall endeavour to take a lunar observation. At 9 o'clock a.m. it cleared up, which enabled me to take one. The remainder of the day very hot. Wind variable, with clouds from every direction; towards sundown it again settled in the south-east, and all the clouds disappeared without any rain falling. Tuesday, 20th May, King's Chain of Ponds. Leaving Mr. Kekwick in charge of the party, I started with Thring, King, and Auld, at half-past nine a.m., on a northern course; at one o'clock p.m. changed to 65 degrees, to what appeared to be a bare hill. At a little more than a mile struck a small watercourse running towards the north; followed it, and at about two miles and a half came on some ponds of water, but not so large as those at our depot; at present they are not more than three feet and a half deep. Examined around the wooded plain to see if there was any larger body of water, but could see none. This plain is covered with small gums, having a dark bluish-green leaf with a grey-coloured bark; there are also a few white ones around the ponds of water, which abound with grass. Before reaching the plain we crossed what seemed to be elevated sandy table land, extending about nine miles, covered with spinifex and dark-coloured gum-trees; we also passed two or three narrow belts of tall mulga and hedge-trees which grow on the stony rises, about twenty feet high. These ponds I name Auld's Ponds, in token of my approbation of his conduct. Wind, south-east. Latitude, 16 degrees 28 minutes 16 seconds.
