At 7.30 a.m. resumed a westerly course through grassy gum forest; at 8.0 a.m. crossed a large watercourse trending south, with many shallow pools of water; the country then became scrubby; at 9.10 crossed a granite ridge and entered a rich grassy valley timbered with eucalypti and raspberry-jam wattle, a small watercourse trending north.  The ridge on the west side of the valley was destitute of timber, but covered with dense wattle brush; at 10.0 a.m. altered the course to 305 degrees, and at 10.35 came on the head of a small stream-bed with pools of water; following it west-north-west, at 11.30 it was joined by a running stream four yards wide, the water being brackish, and trended to the south-west; left it and steered west over an open scrubby country; at 12.30 p.m. entered a dense thicket of eucalypti and acacia, the soil being formed of fragments of granite and trap; at 1.0 p.m. entered a deep valley by an abrupt descent, and found ourselves once more on the banks of the brackish stream, which was much enlarged, and running through a narrow grassy flat backed by high sandstone cliffs from 80 to 100 feet high.  Continuing our course along the river west till 1.55 p.m., when it turned north, and at 2.20 p.m. north-west; at 3.0 p.m. the banks of the stream became very high, and stratified in a remarkable manner, the lower rocks in thin beds dipping to the east, while the superincumbent rocks of red sandstone were horizontal.  We therefore entered the bed of the river to examine it, and found two seams of coal—­one five feet thick and the other about six feet thick—­between beds of sandstone and shale.  Having pitched the tent and tethered the horses, we commenced to collect specimens of the various strata, and succeeded in cutting out five or six hundredweight of coal with the tomahawk, and in a short time had the satisfaction of seeing the first fire of Western Australian coal burning cheerfully in front of the camp, this being the first discovery of coal in the western part of the Continent.

Latitude 28 degrees 57 minutes 10 seconds; longitude 115 degrees 30 minutes.

10th September.

At 7.20 a.m. left the camp and followed the river downwards on a general course 250 degrees; at 7.40 crossed to the left bank, the valley opening out and the soil improving, being formed by the decomposition of soft shales, which contain much gypsum in fine crystals.  Oat and rye grasses were abundant, with plenty of saltbush; at 9.10 crossed to the right bank, and steered 220 degrees to an abrupt headland on the north side of the valley, which was here about two miles wide; the soil a stiff brown loam, with rounded fragments of granite, flinty trap, and quartz, resembling in appearance the French millstone burr; the grass improved, being chiefly of perennial species.  After a halt of twenty minutes to take bearings from the hill, at 9.40 steered 200 degrees, and again crossed the river at 11.15, and altered the course to 235 degrees;
