12th January.
The night was fine, with a heavy dew and a light breeze from the south. At 6.15 a.m. steered north 150 degrees east over the level country which extends along the east side of Jasper Range; the soil is stony, but well grassed, and the fine weather had allowed the surface to become firm, so that the horses were not often bogged. At 12.25 p.m. camped on a small creek between the Fitzgerald and Jasper Ranges; marked a gum-tree at camp Number 9. The general character of this part of the country is good and well suited for stock, though not equal to the basaltic country to the eastward on the Victoria. Hard sandstone, jasper, and coarse limestone are the prevailing rocks.
Latitude by Aldebaran, Saturn, and a Orionis 16 degrees 16 minutes 22 seconds.
FINE PLAINS.
13th January.
The night cool and clear; thermometer 62 degrees at sunrise with heavy dew; steering an average south course from 6.40 a.m. till 11.25, reached the western branch of the Victoria River and encamped. The country traversed was nearly level and well grassed and thinly wooded with eucalypti and bauhinia; the soil is brown loam with small fragments of limestone; the river was running strong, but not in flood; the greatest rise this season had been only ten feet, and the usual flood-marks were twenty feet higher.
Latitude by Aldebaran and Capella 16 degrees 25 minutes 12 seconds.
14th January.
Followed the river to the west-south-west, crossing two large tributary creeks from the north-west, approaching the sandstone ranges on the western side of the plain; the soil did not improve, but became very sandy; the country is thinly wooded with box-trees and bauhinia of small size; grass is abundant and good. At noon one of the pack-horses, Sam, knocked up, and his load being transferred to one of the riding-horses, he was left to rest while we sought a suitable spot for a camp, and at 12.15 p.m. halted at a small gully, as the bank of the river was unsafe for the horses, being very boggy. Sent back for the horse Sam, and brought him to camp; ascended the hill to the north-west of the camp to take bearings, but no important features of the country were visible; in ascending the hill the aneroid (B) fell from 29.62 to 28.55 degrees, and on descending only rose to 28.80 degrees, the estimated height being 300 feet; as this indicated a change in form of the metal of the instrument, I re-adjusted it to the aneroid (A), 29.45 degrees. The continuance of fine weather and forward state of the grass led to the supposition that the wet season had already terminated, though only two months have elapsed since the first rains. It is probable that the wet season is much shorter in the interior than on the coast, and at no great distance inland the tropical wet season will cease altogether, as Captain Sturt, in latitude 26 degrees, only observed a fall of rain in the month of August; but this might be exceptional, as in the case of Dr. Leichhardt, who never encountered a rainy season during the journey to Port Essington.
