Leaving the rock-hole, we steered for Mount Romilly, first following down
the little creek from the gorge until it ran out into the sand in a clump
of bloodwoods. Then crossing a plain where some grass grew as well as
spinifex, we came again into sand-ridges, then another plain, then a
large, dry clay-pan West of Mount Stewart, then more ridges up to the
foot of Mount Romilly. It was here that we must have crossed the route of
Colonel Warburton in 1873, though at the time I could not quite make out
the relative positions of our two routes on the map.

Colonel Warburton, travelling from East to West, would be more or less
always between two ridges of sand, and his view would therefore be very
limited, and this would account for his not having marked hills on his
chart, which are as large as any in the far interior of the Colony. In
his journal, under date of September 2nd, we read: ". . . There are
hills in sight; those towards the North look high and hopeful, but they
are quite out of our course. Other detached, broken hills lie to the
West, so our intention is to go towards them." Then, on September 3rd:
"N.W. by W. to a sandstone hill" (probably Mount Romilly). "North of us
there is a rather good-looking range running East and West with a hopeful
bluff at its Western end" (probably Twin Head). From the top of Mount
Romilly a very prominent headland can be seen bearing 7 degrees, and
beyond it two others so exactly similar in shape and size that we called
them the Twins. For these we steered over the usual sand-ridges and small
plains, on which a tree (VENTILAGO VIMINALIS) new to us was noticed;
here, too, was growing the HIBISCUS STURTII, whose pretty flowers
reminded us that there were some things in the country nice to look upon.

Near the foot of the second headland we made camp. Leaving Charlie behind,
the rest of us set out in different directions to explore the hills.
There are four distinct headlands jutting out from the tableland,
