25th. Travelled onwards about North 40 degrees East for eight miles, passing a low granite range at six miles. Came to a fine brook trending a little south of east, which we followed downwards seven miles, running nearly east. This brook was full of water, some of the pools being eight or ten feet deep, ten yards wide, and sixty yards long. It flowed out into a large flat, and finally runs into a salt lake. I named this brook Sweeney Creek, after my companion and farrier, James Sweeney. Leaving the flat, we struck North-North-East for four miles, and came to a salt marsh about half a mile wide, which we crossed. Following along, came into some high ranges, which I named the Frere Ranges, after Sir Bartle Frere, the distinguished President of the Royal Geographical Society. Found a small rock water-hole in a gully and camped. Water appears exceedingly scarce in these ranges. It is very remarkable that there should have been such heavy rain twelve miles back, and none at all here. Rough feed for horses. Distance travelled about twenty-seven miles. These ranges run east and west, and are the highest we have seen. The marsh appears to follow along the south side of the range. Barometer 28.38; thermometer 70 degrees at 5.30 p.m.; latitude 25 degrees 43 minutes 44 seconds by Arcturus. 26th. Ascended the Frere Ranges and got a fine view to the north and east. Fine high hills and ranges to the north; a salt marsh and low ranges to the east and South-East. Continued on North-East for four miles, then North-North-West for three miles, passing plenty of water in clay-holes and clay-pans in bed of marsh, we camped at a fine pool in a large brook that runs into the marsh, which I called Kennedy Creek, after my companion James Kennedy. The prospect ahead is very cheering, and I hope to find plenty of water and feed for the next 100 miles. Latitude 25 degrees 38 minutes 44 seconds South; barometer 28.42; thermometer 41 degrees at 10 p.m. Marked a white gumtree F 40 close to camp in bed of river. The banks of the brook at this spot are composed of purple-brown slate (Silurian).
