Monday, 12th December, Louden Springs. Still very cloudy; wind south; heavy clouds to north-west; no rain. Finishing the east boundary of Number 3 run. Can find no more springs in or about this run. At sundown still very cloudy, but no rain. Tuesday, 13th December, Louden Springs. Started at 7.15 a.m. to find the lake on an east course. The horses being a long distance off, it was late before they came up. At nine miles crossed the gum creek running north, spread out in a broad valley into numerous courses rich in food for cattle. At twelve miles sand hills commenced, and continued to the shores of the lake, with broad stony plains between, and plenty of grass. At twenty miles crossed the Douglas, running north through sand hills in a broad valley divided into numerous courses, with dwarf gum-trees, mallee, tea-tree, and numerous other bushes; the bed sandy, and no water. At thirty-five miles struck the lake where the Douglas joins it. The country travelled over to-day has been stony plain (undulating), and low sand hills, with abundance of feed, but no water. There is some water at the mouth of the Douglas, but it is salter than the sea. The water in the lake seems to be a long distance off, but the mirage is so very strong that I can form no opinion of it to-night. This seems also a bay I have got into. There is a point of land to the south bearing 25 degrees east of south, and the other bearing 25 degrees east of north. Searched about for water, but could find none. Camped in the creek without any. The country at this part is very low, and nearly on a level with the lake. The only sand hill I shall be able to get a view from is not above thirty feet high. At sundown I got on the top of the sand hill, but could see nothing distinctly; must wait until morning. This creek seems to be very little frequented by natives; can see very few tracks and no worleys.
