Friday, 3rd June, Hawker Springs. I find that the horse is too unwell to proceed. I shall give him another day, for fear I should lose him altogether. I sent Muller to see if there are any springs round the hill about six miles to the east. He states that the creek flows past that hill, and on towards other hills of the same kind. The springs continue to within half a mile of the hill, where he found two large springs running over, covered with long reeds. I do not doubt but that they still continue on towards the lake, (wherever that may be), which I intend to examine on my return.
