Friday, 23rd July, Large East Plain. Started at 9.10 a.m. on a bearing of 82 degrees, and at four miles ascended an isolated hill, but can see nothing of the gum creek. Changed our course to 122 degrees, and at four miles crossed a mulga creek running to the east. Camped on the south-east side of a flat-topped hill, which, although the highest I have yet seen, enabled me to see nothing but the range to the north-east, and a high conical hill about ten miles south-west, connected with the ranges. The country is without timber except a few mulga bushes at intervals. Distance to-day, twenty-one miles.
