The next harbour to the northward is Botany Bay, which is a capacious bay, with excellent anchorage for shipping; but the entrance is very dangerous to those commanders who are strangers to the coast. At the head of the bay is George's River, which extends about sixty miles up the country, and is navigable for small vessels of about 40 tons burden; on the banks of this river there are several settlements, which I shall hereafter describe. Nine miles farther north are the heads of Port Jackson; on approaching the heads from sea, the entrance is so narrow, and the rocks so perpendicular, that the opening is not perceivable at a distance. On the south head is a look-out house, and a flag staff, on which a yellow flag is hoisted on the approach of any vessels from sea, which is answered by another signal staff on a battery at the north end of the town, called Davis's Point Battery, which is to be seen from all parts of the town, so that a vessel is known to be approaching before she enters the port. After entering the heads, the river runs due south for six miles, it then turns short round a point of land on the north shore, called Bradley's Head, which runs due west for twenty-four miles. After rounding Bradley's Head, the town of Sydney is perceivable, about three miles distant on the south shore. The anchorage is a small cove, as still as a mill-pond, land-locked around on all sides; the principal buildings in view are the stores and dwelling of Mr. Campbell, a Bengal merchant; they are built of white stone and have a noble appearance: the next is the government stores, a large stone building, at the end of which is the hospital, wharf, and stairs, the only public-landing place in the cove; here are two centinels continually parading the quay. From the landing place is a fine wide street, called George Street, with several fine stone and brick buildings, extending a mile and a half long, and joining the race ground. The public buildings in this line are the governor's secretary's office, an orphan school for female children, and the military barracks, with many fine private buildings, shops, &c. On the S. E. side of the cove is the government house, a low but very extensive building, surrounded with verandahs, and built in the eastern style, with an extensive park and garden surrounded with a high stone wall. About a quarter of a mile south of the government house is the general hospital, a large and extensive building, erected without any expense to government, the whole having been completed and paid for by three private gentlemen of the colony, for the grant of certain privileges. One mile further S. E. is Wallamolla, a fine brick and stone mansion, the property and dwelling house of John Palmer, Esq., formerly Commandant-general of the colony.
