Lose A horse.

17th January.

Started at 7.5 a.m. and steered a south-west course till 10.30 a.m., passing over a level grassy flat the whole distance; but the soil became more sandy as we proceeded up the river; there is very little wood of any description; the few trees that exist are white-stem eucalypti and a few acacia with pinnate leaves; the horse Sam is very weak, and two other horses are lame and can scarcely travel; since the 3rd of January the distance travelled has not exceeded ten miles per diem; water and grass everywhere abundant, and the loads not heavy, yet the greater part of the horses appear to be unable to perform a greater amount of work.

Latitude by Aldebaran 16 degrees 36 minutes 43 seconds.

18th January.

Some of the horses having strayed towards our last camp, we were detained till 8.10 a.m. and then steered south for three miles; the sandstone hills here closed in on each side of the river, scarcely leaving a passage at the base of the steep rocks; here the horse Sam fell into a pool of water, and when extricated could not stand; this having caused considerable delay, we encamped in a grassy flat half a mile farther on; in the evening sent Bowman and Dean to bring the horse to the camp, but they found him dead; marked a tree near camp 14.

19th January.

The night was fine, with heavy dew, the temperature 73 degrees at sunrise; having collected the horses and saddled at 6.45 a.m., left the camp and followed the valley of the river on an average south-west course, crossing a large creek from the north-west; the valley of the river expanded to three miles and then narrowed to one mile, and the course of the river was nearly west till 10.50 a.m., when we encamped; the soil of the valley is a brown loam, producing abundance of grass; but the hills, though less rocky, are more barren than lower down the river; the character of the channel of the river has altered, and has the appearance of a stream which continues to run late into the dry season, as the channels are narrow and fringed with pandanus, melaleuca, and other trees which grow near permanent water; the banks are of less height and the timber on them grows to a greater size than lower down the valley; at 1.0 p.m. the thermometer 100 degrees, and the wet bulb 76 degrees, indicating 24 degrees of evaporation.

Cross the Wickham river.

20th January.

Left the camp at 6.55 a.m. and followed the river in a west-north-west direction till 8.5, when we crossed at a ledge of rocks which caused a fall of about one foot, the water being twenty yards wide and one to two feet deep; but above and below the rapid the river formed fine reaches seventy yards wide; the course was now west-south-west till 9.0 a.m., when the river turned west, and at 10.50 came to a large stony creek from the south-west, at which we encamped; the country
