I have, etc., (Signed) NEWCASTLE. ... JOURNAL OF THE NORTH AUSTRALIAN EXPLORING EXPEDITION, BY A.C. GREGORY. The preliminary arrangements for the North Australian Exploring Expedition being complete, the stores, equipment, and a portion of the party were embarked at Sydney in the barque Monarch and schooner Tom Tough, and sailed for Moreton Bay on the 18th July, 1855, and on the 22nd anchored at the bar of the Brisbane River. The next day the Monarch attempted to enter the river, but being taken by the Government Pilot half a mile to the east of the channel over the bar, grounded, and was not got off till the 26th, when she entered the river. The steamer Ballarat was engaged to tow the Monarch up to the town of Brisbane; but having struck on a rock near Ipswich, sank, and the steamer Hawk was engaged to tow up the river. The Hawk, however, proved to be of insufficient power, and it was then decided to embark the horses and sheep, which had been collected by Mr. H.C. Gregory, at Eagle Farm. HORSES EMBARKED AT MORETON BAY. The horses having been got on board the Monarch on the 31st July, and the sheep the next day, the steamer Bremer was employed to tow her over the Bar. It was evident, however, that the Bremer did not intend to do this, for she slacked the tow-line, and then steamed ahead full speed and snapped the hawser, and went off without any explanation. Having removed a quantity of stores from the Monarch to the Tom Tough, so as to reduce the draft of the former, on the 8th August warped over the bar and went over to Moreton Island, where about three tons of water were taken in from the fresh-water creeks near the Pilot Station. On the 12 August weighed and left Moreton Bay; and this being the last point of communication with the civilised world, the Expedition might be considered to commence on this date. The party consisted of eighteen persons, as follows: commander A.C. Gregory; assistant commander, H.C. Gregory; geologist, J.S. Wilson; artist and storekeeper, J. Baines; surgeon and naturalist, J.R. Elsey; botanist, F. Mueller; collector and preserver, J. Flood; overseer, G. Phibbs; stockmen, etc., C. Humphries, R. Bowman, C. Dean, J. Melville, W. Dawson, W. Shewell, W. Selby, S. Macdonald, H. Richards, J. Fahey. The livestock comprised fifty horses and 200 sheep. The provisions consisted of flour, salt pork, preserved beef, rice, peas, preserved potatoes, sago, sugar, tea, coffee, vinegar, limejuice, etc., calculated to supply the party on full rations for eighteen months.
