30TH MARCH.--The night had been cool and pleasant, Thermometer at sunrise
only 42°. The cattle were yoked up early, and we travelled on over fine
grassy plains, and with open gravelly ridges on our right. At length,
about the sixth mile, these ridges closed on the river, where there was
one hill almost clear of trees or bushes. I ascended it, but could only
see plains to the westward, and a dense line of river-trees running
north. We at length encamped on what appeared to be still the Narran,
after a journey of about eight miles.

We this day passed a small group of trees of the yellow gum, a species of
eucalyptus growing only on the poor sandy soil near Botany Bay, and other
parts of the sea-coast near Sydney. Thermometer at sunrise, 42°; at 4 P.
M., 83°; at 9, 61°;--with wet bulb, 57°. Mean height of the camps of the
27th, 28th, and 30th, above the level of the sea, 509 feet.

31ST MARCH.--The various lines of trees were now so much dispersed across
the country, that to follow the line of the Narran, it was necessary to
see its ponds and channel as frequently as possible. The course, if not
of the river, at least of its ana-branches; and there were besides those,
branches of another kind, namely, true branches coming from the main
channel, as branches leave the stem of a tree, never to unite with it
again. Some of those of this description, so closely resembled in every
respect the Narran, that the difference was only to be distinguished by
observing the marks of flood on trees, and ascertaining the direction of
the current. We had crossed several such, and were rather in a "fix" with
some lagoons, when I perceived several native children in one of them. I
wished here to intercept some natives who might tell us where was the
ford of "Congo," where white men had crossed the Balonne, or where was
