Sunday, 22nd May, Rain Water. Sent Herrgott to examine the south-west side of the lagoon which we passed last night, with orders to overtake me by 11.30, so that I may get an observation of the sun at noon. The horses having strayed some distance during the night, our start was delayed until 9.15. Started on the same bearing as yesterday, 310 degrees. Stopped at 11.20 for Herrgott to come with the instruments, but he did not come up until 1.15, so that I lost my observation. I had told him, if there was no appearance of springs not to go far, but to return immediately; instead of which he went round the lagoon. Camped on a stony rise, with a little wood. Distance to-day, twenty-one miles.
