rimitive rocks: there were
pebbles of quartz, white, red, and grey; of granite; of sienite; of
felspathic porphyry, hornblende, and quartz-porphyry; and of slate-rock.

The morning was cloudless. In the afternoon, heavy cumuli, which
dissolved towards sunset; a strong wind from the north and north by east.

A very conspicuous hill, bearing E.N.E. from the junction of the rivers,
received the name of Mount Graham, after R. Graham, Esq., who had most
liberally contributed to my expedition.

Mr. Gilbert found a large calabash attached to its dry vine, which had
been carried down by the waters. Several other very interesting
cucurbitaceous fruits, and large reeds, were observed among the rubbish
which had accumulated round the trees during the flood.

April 3.--We travelled up the Burdekin, in a north-north-west direction,
to latitude 20 degrees 31 minutes 20 seconds. The country was hilly and
mountainous; the soil was stony; and the banks of the river were
intersected by deep gullies and creeks. The forest vegetation was the
same as that on the lower Suttor. Among the patches of brush which are
particularly found at the junction of the larger creeks with the river,
we observed a large fig-tree, from fifty to sixty feet high, with a rich
shady foliage; and covered with bunches of fruit. The figs were of the
size of a small apple, of an agreeable flavour when ripe, but were full
of small flies and ants. These trees were numerous, and their situation
was readily detected by the paths of the natives leading to them: a proof
that the fruit forms one of their favourite articles of food. The
drooping tea trees, which had increased both in number and size, grew in
company with an arborescent Calistemon, along the water's edge; and a
species of Eucalyptus, somewhat resembling Angophora intermedia, was
discovered at this spot: it occurs frequently to the northward, and is
common round the gulf of Carpentaria. The small Acacia tree of Expedition
Range was frequently seen in the forest, and was covered with an
amber-coloured gum, that was eatable, but tasteless: Hakea lorea (R.
Br.), and Grevillea ceratophylla (R. Br.); the Ebenaceous tree, and that
with guava-like fruit (lareya), were all numerous. The bed of the river
was covered with the leguminous annual I noticed at the Suttor; it grew
here so high and thick that my companions were unable to see me, though
riding only a few yards from them.
