Wednesday, 21st May, Auld's Chain of Ponds. Started at twenty minutes past eight o'clock a.m., course north. The morning was so thick, with a heavy fog, that I did not get a start till late. At three miles I found another chain of ponds, but not so large; these I name McGorrerey Ponds. Proceeded on the same course and passed through some thick belts of hedge-tree and scrub; the country then opened and became splendidly grassed, with gums and other trees. We also saw, for the first time, a new gum-tree, having a large broad dark-green leaf, and the bark of a nankeen colour, which gave a very pretty effect to the country. At seventeen miles, not finding any water, and having passed five deep holes surrounded with ironstone conglomerate rock similar to Frew's Water Hole, but without any water in them, and to all appearance the dip of the country being to the north-east, I have changed my course to that direction, again travelling over a splendidly grassed country for ten miles, occasionally meeting with low stony rises of ironstone and gravel, at the foot of which were some more deep holes without water. In the last three miles we had to get through a few patches of scrub; the grass is all very dry. No rain seems to have fallen here for a long time. At sundown camped without water. Day very hot. Wind variable, with a few clouds. Latitude, 16 degrees 8 minutes 39 seconds. Thursday, 22nd May, Fine Grass Country. Returned to McGorrerey Ponds. Day very hot, and the horses much distressed for want of water; they have the appearance of being half-starved for a month, and have taken an immense quantity of water, having gone to it about four or five times in an hour. As I am not satisfied that these ponds cease here, I shall try again to-morrow a little more to the east. Wind, south-east.
