edge of rich unwooded downs. We steered on the following courses: 11.10
south-east for three and three-quarter miles; at 1 south-east for one and
three-quarter miles; 1.22 south-south-east for one mile; 1.50 south by
west for one and a half miles back to the creek; 4 south-east for five
and a quarter miles up to the creek; 5.49 north-west for three and
three-quarter miles down the creek to camp. Distance seventeen miles.

April 17.

Jemmy and I left our camp on Dunsmore Creek this morning at 8.5 to go to
the Barcoo River. When we had ridden three or four miles we got on the
watershed of a creek on the Barcoo side of the range. About seven miles
further on we reached the main branch of the creek. It had extensive
flood-marks and heaps of mussel-shells on its banks, but the waterholes
in its channels were empty. I named it the Archer Creek. After following
Archer Creek for thirteen miles we reached its junction with the Barcoo
River. I was glad to find that the channel of the river was full of
water; and as there were fresh tracks of blacks near the river I supposed
them to be in the neighbourhood, so to avoid them I returned up Archer
Creek for about four miles to some fine young grass and encamped. The
country we saw today has in many places a rich soil with grass and
saltbush. It is wooded chiefly with myall and western-wood acacia. Near
the channel of the river there are gumtrees, and on the banks of the
river and Archer Creek there are box-trees. Today we steered to the river
on the following courses: 12.10 east for eleven miles to the left bank of
Archer Creek; 1.20 east for three miles down the creek; 2.28
south-south-east for three miles; 2.52 east for one mile; 3.10
east-south-east for three-quarters of a mile; 4.20 south-east and by
south for two and a half miles; 5 south for one and a half miles; 6
south-east and by south for three-quarters of a mile. Distance
