As much time having been employed in the examination of this port as the various objects I had in view could permit, we prepared to quit it on the following morning. This part of the East Coast had been passed in the night by captain Cook; so that both the openings escaped his notice, and the discovery of the port fell to our lot. In honour of admiral Sir Roger Curtis, who had commanded at the Cape of Good Hope and been so attentive to our wants, I gave to it the name of PORT CURTIS; and the island which protects it from the sea, and in fact forms the port, was called Facing Island. It is a slip of rather low land, eight miles in length, and from two to half a mile in breadth, having Gatcombe Head for its southern extremity.
The northern entrance to Port Curtis is accessible only to boats; but ships of any size may enter the port by the southern opening. Mr. Murray did not find any passage on the south side of the shoal near Gatcombe Head, but could not say that none existed; he thought the deep channel to be not more than a mile wide; but at half a mile from the head there was from 6 to 10 fathoms, and the channel from thence leads fair up the port to beyond South-trees Point; I suspected, however, from the account given by Mr. Murray, that there might be a second shoal, lying not so much as a mile from the head, and one is marked in the plan accordingly, that ships may be induced to greater caution. There is good anchorage just within Gatcombe Head; and at a small beach there, behind a rock, is a rill of fresh water, and wood is easily to be procured.
I cannot venture to give any other sailing directions for going up this port, than to run cautiously, with a boat ahead and the plan upon the binnacle. Both the bottom and shoals are usually a mixture of sand, with mud or clay; but in the northern entrance, and off some of the upper points and islands where the tides run strong, the ground is in general rocky.
The country round Port Curtis is overspread with grass, and produces the eucalyptus and other trees common to this coast; yet the soil is either sandy or covered with loose stones, and generally incapable of cultivation. Much of the shores and the low islands are overspread with mangroves, of three different species; but that which sends down roots, or rather supporters from the branches, and interweaves so closely as to be almost impenetrable, was the most common. This species, the Rhizophora Mangle of Linnaeus, is also the most abundant in the East and West Indies; but is not found at Port Jackson, nor upon the south coast of this country.
Granite, streaked red and black, and cracked in all directions, appeared to be the common stone in the upper parts of the port; but a stratified argillaceous stone was not unfrequent; and upon the larger island, lying off the point of Hill View, there was a softish, white earth, which I took to be calcareous until it was tried with acids, and did not produce any effervescence.
Traces of inhabitants were found upon all the shores where we landed, but the natives kept out of sight after the little skirmish on the first day of our arrival; they subsist partly on turtle, and possess bark canoes and scoop nets. We saw three turtle lying on the water, but were not so fortunate as to procure any. Fish seemed to be plentiful, and some were speared by Bongaree, who was a constant attendant in my boat; and yet our efforts with the seine were altogether unsuccessful. The shores abound with oysters, amongst which, in the upper parts of the port, was the kind producing pearls; but being small and discoloured, they are of no value. The attempts made near the ship with the dredge, to procure larger oysters from the deep water, were without success.
I saw no quadrupeds in the woods, and almost no birds; but there were some pelicans, gulls, and curlews about the shores and flats. Fresh water was found in small pools on both sides of the northern entrance, and at the point of Hill View I met with some in holes; but that which best merits the attention of a ship, is the rill found by Mr. Murray at the back of the small beach within Gatcombe Head.
The latitude of our anchorage at the northern entrance, from four meridian altitudes of the sun, is 23° 44' 16" south.
Six sets of distances of the sun west of the moon, taken by lieutenant Flinders, would make the longitude 151° 21' 22" east; the two time keepers gave 151° 20' 10"; and fifty sets of distances, reduced from Broad Sound by the survey, which I consider to be the best authority, place the anchorage in 151° 20' 15" east.
These being reduced by the survey to the southern entrance, place Gatcombe Head in latitude 23° 52½° S. longitude 151° 24' E.
