We travelled at first to the east, in the direction from which the geese had come last night, but, arriving at ridges covered with scrubby forest, we turned to the north-east, and continued in that direction about seven miles and a half, over iron-stone ridges, when we again entered upon the plains of the river. Mountains and columns of smoke were seen all along its northern banks; but we afterwards found that most of those supposed columns of smoke were dust raised by whirlwinds. We now followed the river until a vine brush approached close to its bank, into the cool shade of which our bullock rushed and lay down, refusing to go any farther; our packhorse and most of our riding horses were also equally tired. The bed of the river had become very narrow, and the water was not quite brine, which made me hope that we should soon come to fresh water. Charley, Brown, and John, had gone into the brush to a camp of flying-foxes, and returned with twelve, which we prepared for luncheon, which allowed our bullock time to recover. They gave an almost incredible account of the enormous numbers of flying-foxes, all clustering round the branches of low trees, which drooped by the weight so near to the ground that the animals could easily be killed with endgels. The Seaforthia palm raised its elegant crown far above the patches of vine brush which we passed at the river side of the ridges.

After a delay of two hours, we again started, and travelled in a due south direction towards some thick smoke rising between two steep and apparently isolated rocky hills: they were about four miles distant, and, when we arrived at their base, we enjoyed the pleasing sight of large lagoons, surrounded with mangrove myrtles (Stravadium), with Pandanus, and with a belt of reeds and Nelumbiums. Man, horse, and bullock, rushed most eagerly into the fine water, determined to make up for the privation and suffering of the three last days. The lagoons were crowded with geese, and, as the close vegetation allowed a near approach, Brown made good use of the few slugs that were still left, and shot ten of them, which allowed a goose to every man; a great treat to my hungry party.

Dec. 5.--I determined upon stopping for a day, to allow our cattle to recover. Every body was anxious to procure geese or flying-foxes; and, whilst three of my companions went to the flying-fox camp which we had visited yesterday, loaded with ironstone pebbles for shot, and full of the most sanguine expectations, Brown was busy at the lagoons, and even Mr. Roper stirred to try his good luck. The two met with a party of natives, who immediately retreated at sight of Mr. Roper; but during the afternoon they came to the other side of the lagoon opposite to our camp, and offered us some fish, a Silurus (Mao) and a tench (?) which they had speared in the lagoons. I made a sign for them to come over and to receive, as presents in exchange, some small pieces of iron, tin canisters, and leather belts; which they did; but they became exceedingly noisy, and one of them, an old rogue, tried to possess himself quietly and openly of every thing he saw, from my red blanket to the spade and stew-pot. I consequently sent Brown for a horse, whose appearance quickly sent them to the other side of the lagoon, where they remained until night-fall. Brown offered them half a goose, which, however, they refused; probably because it was not prepared by themselves, as they were very desirous of getting some of the geese which we had not yet cooked. Brown had shot nine geese, and our fox hunters returned with forty-four of the small species.

When the natives became hungry, they ate the lower part of the leaf-stalks of Nelumbium, after stripping off the external skin. They threw a great number of them over to us, and I could not help making a rather ridiculous comparison of our situation, and our hosts, with that of the English ambassador in China, who was treated also with Nelumbium by its rich Mandarins.

The natives seemed to speak a less melodious language, which might be ascribed to the mountainous character of their country. I collected the following names: Kobboyakka, Nobungop, Kanbinycx, Manguradja, Apirk (Apek), Yaganyin, Kolar, Kadgupa, Gnanga Gnanga. Ayir meant stone spear; Ekolpen, jagged fish-spear.

I made the latitude of these lagoons, by an observation of Castor, 12 degrees 23 minutes 19 seconds.

Dec. 6.--The natives visited us again this morning, and it was evident that they had not been with their gins. They invited us to come to their camp; but I wished to find a crossing place, and, after having tried in vain to pass at the foot of the rocky hills, we found a passage between the lagoons, and entered into a most beautiful valley, bounded on the west, east, and south by abrupt hills, ranges, and rocks rising abruptly out of an almost treeless plain clothed with the most luxuriant verdure, and diversified by large Nymphaea lagoons, and a belt of trees along the creek which meandered through it. The natives now became our guides, and pointed out to us a sound crossing place of the creek, which proved to be the head of the salt-water branch of the East Alligator River. We observed a great number of long conical fish and crab traps at the crossing place of the creek and in many of the tributary salt-water channels; they were made apparently of Flagellaria. Here I took leave of our guides: the leader of whom appeared to be "Apirk," a young and slender, but an intelligent and most active man. We now travelled again to the northward, following the outline of the rocky ridges at the right side of the creek; and, having again entered upon the plains, we encamped at a very broad, shallow, sedgy, boggy lagoon, surrounded with Typhas, and crowded with ducks and geese, of which Brown shot four. It was about four miles east of our yesterday's camp. Numerous flocks of the Harlequin pigeon (Peristera histrionica, GOULD) came to drink at this lagoon; and innumerable geese alighted towards the evening on the plain, and fed on the young grass, moistened by the rain. The number of kites was in a fair proportion to that of the geese; and dozens of them were watching us from the neighbouring trees.

We found a new Eugenia, a tree of rather stunted growth, with broad opposite leaves, and fruit of the size of an apple, of a delicate rose-colour, and when ripe, a most delicious refreshment during a hot day. We had frequently met with this tree on sandstone ridges, and in sandy soils, but had never before found it in fruit. The day was distressingly hot, but we had several light showers during the afternoon.

Dec. 7.--"Apirk," with seven other natives, visited us again in the morning, and it seemed that they had examined the camp we had last left. They gave us to understand that we could travel safely to the northward, without meeting any other creek. Apirk carried a little pointed stick, and a flat piece of wood with a small hole in it, for the purpose of obtaining fire. I directed my course to a distant mountain, due north from the camp, and travelled seven or eight miles over a large plain, which was composed of a rich dark soil, and clothed with a great variety of excellent grasses. We saw many columns of dust raised by whirlwinds; and again mistook them for the smoke of so many fires of the natives. But we soon observed that they moved in a certain direction, and that new columns rose as those already formed drew off; and when we came nearer, and passed between them, it seemed as if the giant spirits of the plain were holding a stately corrobori around us. They originated on a patch of ground divested of its vegetation by a late fire. There was a belt of forest to the northward, and the current of the sea-breeze coming up the valley of the river from N.N.W. seemed to eddy round the forest, and to whirl the unsheltered loose earth into the air.

Towards the river, now to the west of our course, peaks, razor-backed hills, and tents, similar to those we had observed when travelling at the west side of the river on the 3rd December (and probably the same), reappeared. To the east of the mountain, towards which we were travelling, several bluff mountains appeared, which probably bounded the valley of a river flowing to the northward, and disemboguing between the Liverpool and Mount Morris Bay. For the last five miles of the stage, our route lay through forest land; and we crossed two creeks going to the east, and then came to rocky sandstone hills, with horizontal stratification, at the foot of which we met with a rocky creek, in the bed of which, after following it for a few miles, we found water. The supply was small; but we enlarged it with the spade, and obtained a sufficient supply for the night. A thunder-storm formed to the northward, which drew off to the westward; but another to the north-east gave us a fine shower, and added to the contents of our water-hole. A well-beaten foot-path of the natives went down the creek to the south-east. My latitude, according to an observation of Castor, was 12 degrees 11 minutes.
