Monday, 30th April, Under Mount Denison. The wind changed again to the south-east during the night, and is much colder. Started on a course, 315 degrees, across the plain towards Mount Barkly. The highest point of the mount is eighteen miles distant from our camp on the creek. We had to round the west side of it, finding no water until we came upon a little in the gorge coming from the highest point. It was dark before we arrived, so that we could not take the horses up to-night. Wind south-east, blowing a hurricane, and very cold.
