16th. Left Alexander Spring, in company with Windich, to look for water ahead. Steered east for twelve miles, over spinifex sand-hills with some salt-marsh flats intervening. We then turned South-East for seven miles to some cliffs, and followed them along east about one mile and a half, when we saw a clear patch a little to the North-East, on reaching which we found a fine rock water-hole holding over 100 gallons of water. We had a pannican of tea, and gave our horses an hour and a half's rest. Left a note for my brother, advising him to camp here the first night. We continued on a little to the south of east for about fifteen miles over spinifex plains, when we camped on a small patch of feed. Saw a fire about three quarters of a mile south of our camp, and supposed that natives were camped there. 17th. Early this morning we proceeded to where we saw the fire last night, but could not find any natives: it must have been some spinifex burning. We continued about east for two miles; found a rock water-hole holding about fifty gallons, and had breakfast. After this, continued on a little south of east for twelve miles, when we turned more to the north, searching every spinifex rise that had a rocky face, first North and then North-West and West, all over the country, but not over any great extent, as my horse (Brick) was knocked up. About one o'clock we found enough to give the horses a drink, and to make some tea for ourselves. We saw some low cliffs to the north, and proceeding towards them we saw ahead about North-North-East a remarkable high cliff. I therefore decided to make for it. I had to walk and drive my horse before me, and before we reached the cliff we had hard work to get him to move. When we got close we were rejoiced to see cliffs and gorges without end, and descending the first hollow found a fine rock hole containing at least 250 gallons. We therefore camped, as it was just sundown. I am very sanguine of finding more water to-morrow, as our horses will soon finish this hole. There was very little feed about the water.
