At 7.40 a.m. steered east to the South Creek, which we found at the distance of two miles, and followed it up for an hour in search of a crossing place, as the channel was very muddy. A suitable spot having been found, we filled up the channel, which was two yards wide, with pandanus stems, and crossed the horses over without accident. Steering east-north-east two miles across wide level plains, with patches of box-trees, turned north at noon and struck the Albert just below the junction of the South Creek and Beame's Brook. Finding the water brackish, we did not proceed farther down the river, and encamped. The existence of a narrow belt of mangrove along the bank of the river indicates that the water is often salt to the head of the Albert. Latitude by Vega 17 degrees 51 minutes 55 seconds. 2nd September. The water in the river being very brackish, it became evident that we should be unable to procure fresh water if we followed it towards the sea, and therefore I decided on leaving the letters I had written to Mr. Baines at this spot, and accordingly marked a tree thus: NAEXPDN AUG 30 1856 DIG2YDN and buried a tin canister with letters, stating that the exploring party was to start the following morning for Moreton Bay, and instructing Mr. Baines to remain at the Albert till the 29th September, 1856, in case any unforeseen circumstance should compel the party to return to the Albert within that period. Five months' flour, tea, sugar, etc., and three months' supply of meat at full ration still remained; and as our horses would supply the deficiency of meat, if required, we have sufficient quantity of provisions to enable the party to reach the settled part of New South Wales, unless extraordinary difficulties should be encountered; under the circumstances it did not appear prudent to delay at the Albert River, as the arrival of the Tom Tough might be deferred for an indefinite period. 3rd September. Left our camp at 6.45 a.m., and steered east over level box-flats and open grassy plains; at 10.0 came on a small creek, which we followed half an hour to the north-east, when we came to salt-water, which had been left in pools at high tides. I therefore steered south-east till 5.0 p.m. and camped at a shallow pool in a large creek trending north. The country consists of vast open level plains, separated by narrow belts of box and terminalia trees; the soil a brown clay loam, producing rather short and dry grass. On approaching the waterhole at which we encamped, a black and three or four women were found camped on the opposite side of the creek; they climbed the trees and remained among the branches till dusk, when they descended to their fires and made a great noise till 9.0, when they decamped. This creek is probably the head of the salt-water arm of the Albert River or of the Disaster River. Latitude by Vega 18 degrees 2 minutes 5 seconds; variation of compass 4 degrees east.
