The soil of the flat round the lagoon, was very stiff and suitable for making bricks.

The country along the Mitchell was an immense uninterrupted flat with a very clayey soil, on which the following plants were frequent: viz.

Grevillea, Cerotaphylla, and Mimosoides, a Melaleuca with broad lanceolate leaves, Spathodea and a Balfouria, R.Br.
Whilst walking down by the lagoon, I found a great quantity of ripe Grewia seeds, and, on eating many of them, it struck me, that their slightly acidulous taste, if imparted to water, would make a very good drink; I therefore gathered as many as I could, and boiled them for about an hour; the beverage which they produced was at all events the best we had tasted on our expedition: and my companions were busy the whole afternoon in gathering and boiling the seeds.
Charley and Brown, who had gone to the river, returned at a late hour, when they told us that they had seen the tracks of a large animal on the sands of the river, which they judged to be about the size of a big dog, trailing a long tail like a snake.

Charley said, that when Brown fired his gun, a deep noise like the bellowing of a bull was heard; which frightened both so much that they immediately decamped.

This was the first time that we became aware of the existence of the crocodile in the waters of the gulf.
June 20 .-- We travelled about ten miles north-west, and avoided the gullies by keeping at a distance from the river.
