August 5.--We cut our meat into slices, and, although we were reduced in number, we had become so expert, that we had finished a full sized bullock by half past eleven, A. M. The process occupied four of us about four hours and a half; John and Brown were employed in putting it out on the kangaroo net to dry. The strong sea breeze dried it beautifully; but it attracted much moisture again in the night, and was very moist when we packed it into the bags at starting.

The sea breeze set in on the 4th at 11 o'clock, became very strong during the afternoon, lessened at sunset, and died away about 9 o'clock, P. M. when it became thick and foggy. This was the case on the 5th, 6th, and 7th, and was very regular.

August 6.--We left the large lagoon, which, as I was prevented from making an observation, I supposed to be in latitude 17 degrees 47 minutes v. 48 minutes, and followed the winding course of the river up to latitude 17 degrees 57 minutes. The river, I am inclined to think, is the Albert of Captain Stokes, and the Maet Suyker of the Dutch Navigators, and its general course is from south-south-west, to north-north-east. Plains, forest country, open scrub frequently broken by gullies, alternated with each other. Several large and deep basins parallel to the river, were dry. The rough-leaved fig tree, the white cedar, and a stiff-leaved Ipomoea with pink blossoms, grew on its sandy banks; and some low straggling mangroves at the water's edge. The day was far advanced, and I became very anxious about our moist meat; and feared that we should have to encamp without water. We saw burnt grass every where, and logs were even still burning; and fresh water could not be very far off, but yet we were unable to detect it. At last, I observed some trees, of a fresher appearance than usual, beyond a small rise; and, riding up to it, found a small water-hole surrounded by Polygonums: on examination, it was found to contain only a very small quantity of water, yet what remained was good. Charley, who returned afterwards, said that he had been before at this water-hole, and had found a tribe of natives encamped on it, one of whom lifted his spear against him, but his courage forsook him upon observing Charley still riding towards him, when he and the whole camp took to their heels, leaving a good supply of Convolvulus roots, and of Terminalia gum behind them. We found shells of Cymbium and Cytherea, an enormous waddie, which could have been wielded only by a powerful arm, nets and various instruments for fishing, in their deserted camp.

August 7.--I thought it advisable to stop here, and give our meat a fair drying. The natives were not seen again. Charley and John took a ride to procure some game, and came to a salt-water creek, which joined the river about three miles from our camp; the river flowed in a very winding course from the eastward. They found some good fresh water-holes, at the head of the salt-water.

August 8.--We travelled about seven miles E.S.E. over plains and Ironbark ridges. The approaches of the creek, broken by watercourses and gullies, were covered with thickets of raspberry-jam trees. The rock cropped out frequently in the creek, which was said to be very rocky lower down. The salt-water Hibiscus, a species of Paritium, Adr. Juss. (Hibiscus tiliaceus? Linn. D.C. Prodr. I. p. 454) grew round the water-holes. We found the same little tree at the salt-water rivers on the west coast of the gulf, and at Port Essington. I had formerly seen it at the sea coast of Moreton Bay; its bark is tough and fibrous, and the heart-wood is brown with a velvety lustre.

August 9.--When Charley returned with the horses, he told us, that, when he was sitting down to drink at a water-hole about three miles up the creek, ten emus came to the other side of the water; keeping himself quiet, he took a careful aim, and shot one dead; then mounting his horse immediately, he pursued the others, and approaching them very near, succeeded in shooting another. He broke the wings of both and concealed them under water. It is a singular custom of the natives, that of breaking the wings upon killing an emu; as the wings could only slightly assist the animal in making its escape, should it revive. But in conversation with Brown as to the possibility of one of the emus having escaped, he said very seriously: "Blackfellow knows better than white fellow; he never leaves the emu without breaking a wing. Blackfellows killed an emu once, and went off intending to call their friends to help them to eat, and when they came back, they looked about, looked about, but there was no emu; the emu was gone--therefore the Blackfellows always broke the wings of the emus they killed afterwards." This was, however, very probably one of Brown's yarns, made up for the occasion.

I sent Mr. Calvert and Charley to fetch the game, whilst we loaded the bullocks, and by the time they returned, we were ready to start. The emus were fine large birds, but not fat; this season seemed to be unfavourable for them. When we came out into the plain, we saw the smoke of the natives to the southward, and I steered for it, supposing that they were either near the river, or at all events not far from fresh water. After two miles travelling, we crossed another creek with fine Polygonum water-holes, and, emerging from it into a second plain, we saw a flock of emus in the distance. Chase was given to them, and with the assistance of Spring, one was caught. Loaded with three emus, we travelled over a succession of plains, separated by narrow belts of timber, mostly of-box, bloodwood, and tea-tree. The plains were broken by irregular melon-holes, which rendered our progress slow and fatiguing. We came to Ironbark ridges, and to the very spot where the natives had been burning the grass, but no watercourse, nor lagoon was seen. Brown rode farther to the southward, and observed the tracks of the natives in that direction, but found nothing but box-tree flats. I sent Charley forward to the westward, and followed slowly in the same direction; night overtook us, when we were crossing a large plain, but Charley had lighted a large fire, which guided us, and made us believe that he had found water. He was indeed at the steep banks of the river Albert, but it was still salt. We hobbled and tethered all the horses, and watched the bullocks. Fortunately we had provided ourselves with some water, which allowed half a pint to every man, so that we felt the inconvenience of a waterless camp less than formerly. Besides, we had fresh meat, which made a great difference in our desire for water. It was a beautiful night, and even the dew was wanting, which had been such a hindrance to drying our meat during the previous nights. During my watch, I seated myself on one of the prominences of the steep banks, and watched the loud splashings of numerous large fish which momentarily disturbed the tranquillity of the mirror-like surface of the water. Brown had found a bar across the river, and, on examination it proved perfectly dry during low water, and allowed us to cross, after having brought our bullocks and horses down the steep banks, which, however, was not effected without great difficulty. We had most fortunately hit the very spot where such a crossing was possible. Brown saw a great number of fine fish in the river, which he called "Taylors." The natives had been here frequently: the grass had been recently burnt, and fish bones indicated this as one of their habitual camping places. We could not, however, discover where they quenched their thirst. I sent Charley forward in a north-west direction to look for water. When we came out into the plains which stretched along both sides of the river as far as the eye could reach, we saw smoke very near us on the right. I went towards it, until I found that it rose on the opposite side of the river we had just crossed; Brown, however, detected a pool of slightly brackish water in a deep creek at a short distance from its junction with the river. It was too boggy for our cattle to approach, but it allowed us to quench our own thirst. We now re-entered the plains, and followed the track of Charley, who soon returned with the pleasing intelligence that he had found some fine water-holes. These were in the bed of a creek, surrounded by a band of forest composed of box, raspberry-jam trees, and the broad-leaved Terminalia, the fruit of which was eaten by the black cockatoo. The slopes of the water-holes were steep and boggy, and one of our bullocks was so exhausted that he slipped on the steep banks, rolled into the water, and got so severely bogged, that we were compelled to kill him, after trying everything in our power to extricate him. On the 12th August we cut him up. The night, however, was very foggy with heavy dew, which prevented the meat from drying. The miserably exhausted state of the animal had rendered the meat very flabby and moist, and it not only dried badly, but was liable to taint and to get fly-blown.

August 13.--We had a fine sea-breeze from the northward, which dried the outside of the meat well enough, but not the inside, so that it became in many parts so putrid that I had to throw them away, although we saved a good deal by splitting the puffed pieces, and exposing the inside to the air.

The natives had surrounded the water-hole on which we encamped with a barricade or hedge of dry sticks, leaving only one opening to allow the emus to approach the water. Near this the natives probably kept themselves concealed and waited for the emus; which in these parts were remarkably numerous. On the 11th, John, Charley, and Brown, rode down three birds, and, on the 14th, they obtained four more, two of which were killed by John Murphy, who rode the fleetest horse and was the lightest weight. The possibility of riding emus down, clearly showed in what excellent condition our horses were. Even our bullocks although foot-weary upon arriving at the camp, recovered wonderfully, and played about like young steers in the grassy shady bed of the creek, lifting their tails, scratching the ground with their fore feet, and shaking their horns at us, as if to say, we'll have a run before you catch us.

The latitude of these water-holes was 18 degrees 4 minutes 27 seconds, and they were about nine miles from the crossing place of the river, which I calculated to be in longitude 139 degrees 20 minutes (appr.). The plains were covered with flocks of small white cockatoos, (Cocatua sanguinea, GOULD.) which Mr. Gilbert had mentioned as having been found in Port Essington: their cry was rather plaintive, and less unmelodious than the scream of the large cockatoo; nor were they so shy and wary, particularly when approaching the water.
