Made an early start, and travelled four miles on a south-west course, when the river divided into two channels, the main one coming from a deep gorge to the south-south-east, exactly in the direction in which we had left the Strelley on our outward route, at a distance of about thirty miles; identifying the stream with some degree of certainty. Taking the western branch, which would lead us towards the Yule, we followed it up until long past noon into a hilly country, without meeting with water; we, however, saw a large extent of fine grazing land which would make an excellent summer station when the flats were inundated. Having rested during the heat of the day, which had lately become rather oppressive, we resumed a westerly course, having run out the head watercourses of the western branch of the Strelley. A few miles brought us to a considerable stream-bed trending to the north-west, which was followed down till some time after dark, having procured a few gallons of water from a native well in the bed of a creek. To-day we had travelled for nine hours, and accomplished a distance of twenty-two miles, the longest day's march we had made for many weeks past. Early in the day we had noticed what we took for a great number of native fires springing up in all directions, and quickly to die away again; we, however, found it to be a number of whirlwinds, carrying with them huge columns of charcoal and dust, which traversed the plains sometimes for miles before they broke.
