butary creeks, and
at 3.40 p.m. camped on the bank of the creek, which was now much reduced
in size. The country to the north of the creek consisted of very rough
and rocky hills of red sandstone, extremely barren in appearance, while
to the south it rose into the basaltic plain which forms Roe's Downs.

Latitude by Argus 17 degrees 6 seconds.

16th April.

Resumed our journey at 6.45 a.m. and travelled in a west by north course
towards a remarkable basaltic hill, which I called Mount Sanford,
traversing a fine open grassy country till 1.0 p.m., when we camped on a
creek with permanent pools of water. The rough stony country has rendered
the horses quite footsore, and their legs are much cut and bruised by
constantly falling over the large rocks in crossing the deep ravines and
rocky ridges.

Latitude by Vega 16 degrees 59 minutes 38 seconds.

RETURN TO DEPOT CAMP.

17th April.

Started at 6.25 a.m. and reached Mount Sanford at 7.30, the country
passed being sandstone producing triodia and a little grass. The hill is
of basalt with a flat top, but is based on sandstone; its form is nearly
a truncated cone 150 feet high and 300 feet in diameter at the top.
Having taken angles to the surrounding hills, we descended and steered
south-west and west to the depot camp at 1.0 p.m. During our absence Dr.
Mueller had found full employment in collecting the plants in the
vicinity of the camp, and the rest of the party had been fully occupied
in the care of the horses and duties of the camp. I was glad to find that
they had not been again molested by the blacks.

18th April.

Preparing maps of the late excursion to the east of the depot; party
preparing for the return to principal camp.

19th April.

Party employed as before.

20th April (Sunday).

A fine cool breeze from the south, with thin clouds.

21st April.

Several of the horses had strayed some distance from the camp, and we did
not start till 12.30 p.m., when we steered north by west till 5.15 p.m.
and camped at a small creek in a deep rocky valley; the country after
leaving the basaltic plain was very rocky, the hills composed of schist
with a superstratum of red sandstone; grass was abundant in the valley,
but the hills produced little but triodia and small gum-trees.

START FOR MAIN CAMP.

22nd April.

At 6.45 a.m. steered east down the creek one mile to its junction with
Depot Creek, which was followed north and north-north-east till 8.40. The
