At noon on the 9th March, 1835 I had, at length, the satisfaction of seeing this party leave Parramatta with an equipment fit for the undertaking. The boats appeared to swim very well in their carriage, which was followed by seven carts, and as many packhorses, affording the means of carrying provisions for five months. Two mountain barometers were borne by two men, the only service required of them while travelling. The whole party in motion towards the unknown interior, and prepared for sea or land, was to me a most gratifying spectacle. The cares of preparation were at an end, and I could still count on three weeks of comparative leisure at Sydney, during which time I could arrange the business of my office. The cattle station at Buree, where I intended to commence operations, was distant 170 miles from Sydney, and as it was necessary that the party should travel slowly in crossing the mountains with the boat-carriage, and equally indispensable that the cattle should rest some days after arriving at Buree; I calculated that the expedition could not be ready to advance from that point in less than three weeks from the time at which it left Parramatta. MY DEPARTURE FROM SYDNEY. On the 31st of March I quitted Sydney on the important errand of geographical discovery. My horse, which had been in training by Brown for some weeks, seemed impatient of roads, and full of spirit, a pleasant sensation at all times to the rider, and very congenial to the high excitement of such an enterprise. We soon arrived at Parramatta, where I obtained the loan of a good chronometer from Mr. Dunlop at the observatory. Having noted various important memoranda and suggestions, and partaken of an early dinner, I bade my scientific and obliging friend farewell, and pursued my journey along the western road. WESTERN PART OF CUMBERLAND. I arrived in a few hours at Emu ferry, on the river Hawkesbury, the boundary there of the county of Cumberland. I had traversed the county in its greatest width by this western route; and thus crossed by far the best portion. Unlike the northern sandstone district, where the road towards Wiseman's ferry could be made only by following one continuous ridge, the surface being intersected by deep and precipitous ravines, we were enabled here, the surface rock being trap, to travel along a perfectly straight road over a gently undulating surface. The soil in this district is good, consisting chiefly of decomposed trap. The land is wholly in the hands of individuals, and, in a climate sufficiently moist, would answer well for cultivation. The road passes near Prospect Hill, which is the most conspicuous eminence in the county, and is cultivated to the summit. The rich red soil derived from the subjacent trap-rock produces crops as abundantly now as when it was first tilled, upwards of thirty years ago.
