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.
