Twelve miles to the eastward of Cape Locker the shore is lined with mangroves, among which a small opening, like a rivulet, was observed.  On attempting to approach it, we were prevented by a reef of rocks that stretched across its entrance; but we succeeded in finding an anchorage about three miles to the eastward of the inlet, in two and a half fathoms at about a quarter of a mile from the shore.

February 20.

The following morning, we ascended it in a boat for four miles.  On our way to the entrance, which was between the reef and the shore, we had some difficulty, even with the boat, in finding a channel; but when we were within the heads, we found a regular depth of from ten to twelve feet, the banks on either side were, for two miles, impenetrably lined with mangrove bushes, which bore the marks of having been torn down by freshes or inundations.  Beyond this the banks were low and sandy, but the channel of the river was of mud.  At high water we landed to examine the country, and ascended a sand-hillock, the only elevation we could find, to procure a view around; it was so low that our prospect was very limited, yet still it was sufficient to satisfy us of the aridity and poverty of the soil:  the country bore the appearance of having been under water, which seemed to be occasioned by high tides, for there were large patches of salt incrustations, which could only have been caused by an inundation of sea-water.  Two or three stunted bushes of a species of eucalyptus were the only trees seen, excepting the mangroves.  The soil is composed of a mixture of red quartzose sand, mud, and clay, in which the first bore the greatest proportion.

On no part of the coast did we find the heat so intense and oppressive as in this river; the thermometer stood at 94 degrees, and the ground was so heated that we were obliged to beat a bush down to stand upon, whilst we were taking the bearings of some of the islets in the offing.

Some natives and a dog had very recently been crossing the little creeks that fell into the river, for the impressions of their feet were observed below the high-water mark; the mouths of the creeks were planted with weirs, similar to those in the river at Oyster Harbour.

The river appeared to abound in fish, but the only sort that was caught was what the sailors called cat-fish; they were of a nauseous taste.  Pelicans and curlews were very numerous, particularly the latter, in consequence of which the inlet was called Curlew River; but the most numerous and annoying of the inhabitants of this part were the flies, from their constantly creeping into the eyes, nostrils, and mouth, particularly during our meals; and it required some little trouble to partake of our repast without also conveying with it several of these troublesome insects.

On our return to the cutter, our party very imprudently bathed, which occasioned, to some of them, two or three days’ indisposition, and it was fortunate that they did not suffer from a coup de soleil.  This indiscretion was, however, never afterwards permitted.
