the human constitution; for, without the comforts which the civilized man thinks essentially necessary to life; without flour, without salt and miserably clothed, we were yet all in health; although at times suffering much from weakness and fatigue.  At night we stretched ourselves on the ground, almost as naked as the natives, and though most of my companions still used their tents, it was amply proved afterwards that the want of this luxury was attended with no ill consequences.

We heard some subdued cooees, not very far from our camp, which I thought might originate from natives returning late from their excursions, and whose attention had been attracted by our fires.  I discharged a gun to make them aware of our presence; after which we heard no more of them.

June 22.—­We travelled about twelve miles N. W. 6 degrees W. to lat. 16 degrees 3 minutes 11 seconds, and encamped at a swamp or sedgy lagoon, without any apparent outlet; near which a great number of eagles, kites, and crows were feasting on the remains of a black Ibis.  We passed a very long lagoon, and, in the latter part of our stage, the country had much improved, both in the increased extent of its forest land, and in the density and richness of its grass.

June. 23.—­We travelled eight or nine miles in a W. N. W. direction to latitude 16 degrees 0 minutes 26 seconds, over many Bauhinia plains with the Bauhinias in full blossom.  The stiff soil of these plains was here and there marked by very regular pentagonal, hexagonal, and heptagonal cracks, and, as these cracks retain the moisture of occasional rains better than the intervening space, they were fringed with young grass, which showed these mathematical figures very distinctly.  We passed a great number of dry swamps or swampy water-holes; sometimes however containing a little water.  They were surrounded by the Mangrove myrtle (Stravadium), which was mentioned as growing at the lower Lynd.  The bottom of the dry swamps was covered with a couch grass, which, like all the other grasses, was partly withered.

Bustards were numerous, and the Harlequin pigeon was seen in large flocks.  Wallabies abounded both in the high grass of the broken country near the river, and in the brush.  Mr. Roper shot one, the hind quarters of which weighed 15 1/2 lbs.:  it was of a light grey colour, and was like those we had seen at Separation Creek.  Charley and Brown got seventeen ducks, on one of the sedgy lagoons.

I visited the bed of the river:  its banks were covered with a rather open vine brush.  Palm trees became numerous, and grew forty or fifty feet high, with a thick trunk swelling in the middle, and tapering upwards and downwards.  Sarcocephalus, the clustered fig-tree, and the drooping tea-tree, were also present as usual.  The bed of the river, an immense sheet of sand, was full a mile and a half broad, but the stream itself did not exceed thirty yards in width.

During the night we had again a few drops of rain.
