In the morning early, we set off on our return, and encamped on the 7th at night, about twenty-six miles down: at seven in the morning of the 8th, we embarked again, and by four in the evening had reached a point about forty-three miles down, where we pitched our tents for the night, which was very foggy. In our way down, we stopped, and measured the perpendicular height of a hill on the north side of the river, (or more properly one of the banks of the river; for it is a long range of level land, and nearly perpendicular from the water; the opposite shore is low and marshy;) which I found to be 399 feet: the river was here 120 fathoms wide.
On the 9th in the morning, we proceeded to examine some of the inferior branches; their general direction was to the southward, and the longest was not more than five or six miles in length, and was navigable for such boats as ours; the general depth was three and four fathoms for about four miles up, and then shoal water; the others were inconsiderable.
In one of these branches we passed the night of the 9th, and saw a few natives, who came off to us in their boats with much chearfulness and good humour; I thought I had seen them before: they received a few presents, among which was a looking-glass, which we took much trouble to show them the use of: they were some time before they observed their own figure in the glass, but when they did, they turned it up and looked behind it; then pointed to the water, signifying that they could see their figure reflected as well from that.
Having now examined every thing which was thought worth our attention, we made the best of our way to Mullet-island, where we landed on the 10th in the evening, and caught some fish. This night, and all the next day, (11th,) it blew a gale of wind from the southward, so that we were obliged to pass a second night here. In the morning of the 12th, it was more moderate, although very squally and unsettled; we struck our tents and sailed for Pitt-water, where about noon we encamped upon a point pretty high up.
In our way, we put ashore to fill some fresh water, and in a cave near the stream we found a native woman, who appeared to have been dead some time, for her skin was as hard as a piece of leather; it was impossible to know whether she had died of the small-pox or not.
In the morning of the 13th, as we intended to land well up this branch, in order to avoid the most difficult and tiresome part of the road to Port Jackson. We embarked, after we had breakfasted, and rowed up about a couple of miles, when the party for walking went on shore, each with his arms, and knapsack, containing two days provisions; we were about half an hour in getting through the wood, which led us to the sea-coast, where we fell into our old and well known path, and by four o'clock in the afternoon arrived at the north part of Port Jackson; but we might as well have been fifty leagues off, for here we could have no communication either with the Sirius or the settlement, and no boat had been ordered to meet us. We went immediately to work and made a large fire, by which we lay all night, which happened to be very cold.
The next day we crossed the hills, and came to the mouth of the north-west harbour, but could not find the means of crossing it; muskets had been frequently fired during the night, in hopes that some boat might have been down the harbour fishing, and heard them. We found this morning a canoe upon the beach, with which we had no doubt of getting two men across the water, who could in a short time walk over to the cove where the Sirius lay; but this prospect was disappointed by the first man who entered the canoe having overset her, and she immediately sunk, and he was obliged to swim ashore: after this we went to work and made a catamaran, of the lightest wood we could find, but when finished and launched, it would not, although pretty large, bear the weight of one man.
It was now proposed to walk round the head of the north-west harbour, which would have been a good long journey for at least two days, and our provisions were nearly expended; to this proposal I was under the necessity of objecting, for want of shoes, the last march having tore all but the soals from my feet, and they were tied on with spun-yarn; I therefore declined the proposed walk, and determined to go back to Broken-bay and rejoin the boats; which I had no doubt of being able to effect in the course of that day, and with far more ease than I could, without shoes, climb such rocky mountains, and thick woods, as lay in the way round the head of the north-west harbour. But as it was likely I might fall in with some parties of the natives in the way, I wished to have a companion.
Captain Collins preferred accompanying me in the intended walk, and we were just upon the point of setting out, when two of the people who were with us proposed swimming over the water, and to cross through the wood to the Sirius; the distance they had to swim was not more than two cables length, or four hundred yards; they immediately stripped, and each having had a dram, they tied up in a handkerchief a shirt, trowsers, and a pair of shoes each, which was rested upon their shoulders: thus equipped, they took the water, and in seven minutes landed on the opposite shore; but one being seized with the cramp, was obliged to disengage himself from his bundle, which was of course lost: they set off through the woods, and in a short time got on board the ship, the one with his shirt and trowsers, the other perfectly naked.
Upon their information, a boat was sent down, and took us on board, after a pretty fatiguing journey. I cannot help here remarking how providential it was, that we did not all agree to walk round the north-west harbour. At eight in the morning we heard the report of a great gun, which led me to suspect that some person belonging to the Sirius was missing, and had probably been lost in the woods; we frequently fired muskets that morning, and sometimes imagined we heard a musket at a considerable distance in the woods; in consequence of this suspicion, we frequently fired several together, and as often heard the report of that which we believed was meant to answer us.
