after dark. The
pools here were somewhat larger than for many miles below, being from
sixty to eighty yards wide and half a mile in length, the water in them
becoming decidedly brackish; samphire, atriplex, and other salsolaceous
plants being abundant on the banks.

We only advanced nine miles, owing to Mr. Moore and Dugel having to
return for one of the water-beakers, which had been torn off the
pack-saddle the previous night in a thicket. Towards our bivouac, which
was in latitude 26 degrees 23 minutes 38 seconds, the country near the
river improved much, the channel of the river becoming very shallow; the
water had spread over the flats for more than half a mile on either side,
large flooded-gum trees growing abundantly with a fine sward of grass
beneath, the soil being a rich brown clay loam. Gallinule and cockatoos
were in large flocks feeding on the grass seeds, which were now nearly
ripe.

28th April.

To latitude 28 degrees 7 minutes the river continued to come from north
by east through an extensive plain, bounded on the west by a low range of
trap and granite hills, at an average distance of six or seven miles,
while to the eastward only a few distant peaks were visible, flooded-gum
growing plentifully for more than a mile back from the river, on flats of
tolerably good pasture. Receding somewhat further from the river, the
country opens out into extensive plains yielding but little grass;
atriplex bush and thinly scattered stunted acacia and melaleuca trees
forming almost the entire vegetation.

29th April.

A few miles nearly north brought us to where a considerable tributary
joins the Murchison from the north, the river trending first north-east,
then east, and finally towards the afternoon it came from the southward
of east, our bivouac being only seven miles north of the previous night,
while we had made nearly eighteen miles of easting. The bed of the river
had gradually become more rocky as we ascended, gneiss with quartz dykes
passing through it and yielding a large quantity of salt, rendered the
running water of the river scarcely drinkable; the only fresh water was
found in the back channels filled by the late inundations. The ranges
which ran parallel to the river to the westward terminated some miles to
the north of the bend. Another range, apparently granitic and broken up
into detached peaks, commencing a little to the eastward of its
termination, runs east for about twenty
