Wednesday, 7th March, William Springs. The night very hot and cloudy, with the wind from the west, but without rain. Started for Louden Spa,* (* The Louden Springs of the two last expeditions.) the first few miles being over low sand rises and broad valleys of light sandy soil, with abundance of dry grass; by keeping a little more to the north-west the sand rises can be avoided. At seven miles we struck a swamp, but could see no springs. On approaching the Douglas the country becomes more stony, and continues so to the Spa, where we camped.
