Started at 6.30 a.m. and pursued a south course till 8.0 a.m., when we crossed the ridge at the source of the creek and ascended some stony gullies to the south-west; at 10.40 a.m. halted at a small waterhole in a small creek. Re-commenced our journey at 3.0 p.m., and followed a valley to the south-east; but finding the country in that direction unsuited for our object, turned to the west and reached the creek again at 5.15 p.m.; followed it till 6.0 p.m. to the south-west, and encamped. There was abundance of water in the creek, and the rank growth of the grass on its immediate banks proved a great impediment to the horses. The back country, however, was very rough and stony, thinly timbered with white-gum eucalyptus of small size, and nearly destitute of leaves; and though the whole country was grassy, it was so much parched by the intense heat that it presented a very sterile aspect; at 4.30 p.m. there was a heavy thundershower. 15th October. As the creek below the camp trended to the west and entered a deep rocky gorge in the sandstone range, we steered south at 7.0 a.m., crossing several stony ridges with small gullies and creeks trending west; at 10.20 a.m. crossed the highest ridge, and observed a succession of low stony ridges occupying the space between us and the Sea Range. Descending, we reached a creek, on the bank of which we halted at 11.30 a.m. Here we caught several small fish in a deep pool in the creek. 15th October. Resuming our route down the creek at 2.30 pm, the average course was south-west till 5.30, when we were encamped at a large deep pool or reach of water three-quarters of a mile long and fifty yards wide, supplied by a small stream. Great numbers of large bats were seen hanging in the trees on the margin of the creek, some of which we shot; the flesh was white and was eaten, but it had an unpleasant flavour. The country during this day's journey has not been so hilly as yesterday, and near the camp the trees have retained a few leaves. The soil, however, shows no improvement, being universally stony, and though well-grassed, the country is useless for any purpose than feeding stock. The gouty-stemmed tree (adansonia) is more frequent on the banks of the creeks; pandanus and fig trees prevail near the water, and eucalypti on the hills. Latitude 15 degrees 17 minutes 50 seconds. THE VALLEY OF THE VICTORIA RIVER. 16th October.
