Sunday, 15th May, Mr. Babbage's Old Camp. It cleared off during the night, but the clouds have come up again this morning and look very threatening. Sent Herrgott to find the spring. The wind is still from the same quarter, and too strong for me to do anything to the plan, which is a great annoyance. I will finish the survey of the runs from this place, and send Campbell back to Oratunga with the plan. Herrgott did not return until after sundown: he could not find the spring. Monday, 16th May, Same Place. Sent Muller to the west; he returned at 10 o'clock, having found the spring about two miles and a half distant from the camp; it is not hot, but a little warmer than milk-warm. There is a good stream running from it, and the water is excellent; to me it has a mineral taste, very good. There were some small fish lying dead on the bank, near the mouth; they seemed to have been left there by the retiring of the flood--they were quite dried up. I intended to have taken some with me, but they were too dry--nothing but skin and bone. The creek empties itself into the lake, about a mile north from where Chambers Creek goes into it. Tuesday, 17th May, Same Place. Again very cloudy, with a little rain. Busy finishing the survey. Could not obtain an observation of the sun. Wind still very strong. Wednesday, 18th May, Same Place. Weather clearing up. Engaged with survey. Thursday, 19th May, Same Place. Finishing tracings, etc. Friday, 20th May, Same Place. At sunrise started Campbell for Oratunga with tracings, letter, etc., with orders to proceed to Finniss Springs, thence to Herrgott Springs, thence to St. A'Becket's Pool, thence to Mount Glenns, thence to Mount Stuart, and thence to Oratunga, taking six days to perform the journey. Preparing my other plans for a start to-morrow for the north-west, to see what the Davenport range is. Latitude, 29 degrees 23 minutes 20 seconds. Saturday, 21st May, Same Place. Started at 8 o'clock on a bearing of 310 degrees for the Davenport range. At twenty-two miles changed our course to examine a large lagoon to the south-west of us, bearing 238 degrees. At two miles reached the lagoon, which we examined for springs, but found none. I suppose it receives Major Warburton's salt creek. It is caked with a crust of salt, and is dry; it is seven miles long by three broad, running north-west and south-west. On the south-west side it is bounded by steep cliffs, and high sand hills on the top. Changed to 310 degrees, our original course. Came upon some rain water at four miles, and camped for the night. Distance to-day, twenty-eight miles.
