The next day I went with two boats, accompanied by Mr Banks and the other gentlemen, to examine a large river that empties itself into the head of the bay. We rowed about four or five miles up, and could have gone much farther if the weather had been favourable. It was here wider than at the mouth, and divided into many streams by small flat islands, which are covered with mangroves, and overflowed at high water. From these trees exudes a viscous substance which very much resembles resin; we found it first in small lumps upon the sea beach, and now saw it sticking to the trees, by which we knew whence it came. We landed on the east side of the river, where we saw a tree upon which several shags had built their nests, and here therefore we determined to dine; twenty of the shags were soon killed, and being broiled upon the spot, afforded us an excellent meal. We then went upon the hills, from whence I thought I saw the head of the river. The shore on each side, as well as the islands in the middle, were covered with mangroves; and the sandbanks abounded in cockles and clams: In many places there were rock oysters, and everywhere plenty of wild fowl, principally shags, ducks, curlieus, and the sea-pie, that, has been described before. We also saw fish in the river, but of what kind we could not discover: The country on the east side of this river is for the most part barren and destitute of wood; but on the west it has a better aspect, and in some places is adorned with trees, but has in no part the appearance of cultivation. In the entrance of the river, and for two or three miles up, there is good anchoring in four and five fathom water, and places very convenient for laying a vessel on shore, where the tide rises and falls seven feet at the full and change of the moon. We could not determine whether any considerable stream of fresh water came into this river out of the country; but we saw a number of small rivulets issue from the adjacent hills. Near the mouth of this river, on the east side, we found a little Indian village, consisting of small temporary sheds, where we landed, and were received by the people with the utmost kindness and hospitality: They treated us with a flat shell-fish of a most delicious taste, somewhat like a cockle, which we eat hot from the coals. Near this place is a high point or peninsula, projecting into the river, and upon it are the remains of a fort, which they call _eppah_, or _heppah_. The best engineer in Europe could not have chosen a situation better adapted to enable a small number to defend themselves against a greater. The steepness of the cliffs renders it wholly inaccessible from the water which incloses it on three sides; and, to the land, it is fortified by a ditch, and a bank raised on the inside: From the top of the bank to the bottom of the ditch, is two-and-twenty feet; the ditch on the outside is fourteen feet deep, and its breadth is in proportion. The whole seemed to have been executed with great judgment; and there had been a row of pickets or pallisadoes, both on the top of the bank and along the brink of the ditch on the outside; those on the outside had been driven very deep into the ground, and were inclined towards the ditch, so as to project over it; but of these the thickest posts only were left, and upon them there were evident marks of fire, so that the place had probably been taken and destroyed by an enemy. If any occasion should make it necessary for a ship to winter here, or stay any time, tents might be built in this place, which is sufficiently spacious, with great convenience, and might easily be made impregnable to the whole country.
