Riding under a hanging wood of the angophora, which had ceased for a time, we were induced to break off to our right, to examine some large flooded-gum trees about a couple of miles to the N.W.of us.

On arriving near them, we were astonished to find that they concealed a serpentine lagoon that had a belt of reeds round it.
Keeping this lagoon upon our right, we at length came to the head of it, past which the river sweeps.

Crossing the channel of the river, we continued to ride in an easterly direction to examine the country.

In doing this, we struck on a second branch of the Castlereagh, leading W.by N.into a plain, which it of course inundates at times, and running up it, we found its bed at the point of separation, to be considerably higher than that of the main channel, which still continued of pure sand--and was stamped all over with the prints of the feet of natives, kangaroos, emus, and wild dogs, We then turned again to the head of the lagoon, and took the following bearings of Arbuthnot's range: Mount Exmouth ..........
