Camp 31. Cool during the night with a heavy dew, beautiful morning, not a breath of wind: keeping a short distance from the creek to cross a boggy tributary from the east, for two and three-quarter miles, then through timbered stony rising ground, plenty of feed; the bronzed middle-sized pigeon of Cooper's Creek seen here; bearing of 40 degrees for two and a quarter miles along limestone and plum-pudding slopes; part of creek on left on bearing of 30 degrees for three and a quarter miles, timber for building purposes to be had here in sufficient quantities; bearing of 45 degrees for three-quarters of a mile; bearing 50 degrees for one mile; bearing of 40 degrees three-quarters of a mile over myall open country, some of it very stony where the flood has swept over it; now on the right are some fine plains backed in by low myall ridges; bearing of 42 degrees for four and three-quarter miles, the creek on the left, tributaries seem to come in and join on opposite side, cross a creek from east in its swamp, plenty of water (Kell's Creek); I have come to a stony crossing-place and recross over to north-west side; the female camel bogged but we soon got her put to rights; for the last three miles the ground we travelled over is nearly one mass of stones, limestone and agate or flint, and very bad travelling; the creek runs strong--I have called it Mueller's Creek after F. Mueller of Melbourne--fifteen and a half miles. After getting to camp got a horse and went out north of west to a ridge some short distance off and saw to the westward a large tributary that I think will suit my course; at little over quarter of a mile a very large creek comes in from north of north-east and flows southward, it has ceased running and has a broad stony bottom but has splendid reaches of water; this I have called the Robinson after J. Robinson, Esquire, of Hume River. Considerably to east is a well-defined range in the distance, running north and south with three detached mounds of hills and I have called it Mount Mueller after F. Mueller, Esquire. Wednesday, April 9.
