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.
