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.
