July 10.--The country worse than yesterday, being exceeding low and marshy, with many thick scrubs. About eleven o'clock it opened, being more thinly clothed with the acacia pendula: having travelled about ten miles, we arrived on the borders of a large apparent plain, on which I had proceeded about two miles, when we were suddenly stopped by deep water among reeds; from hence I could distinctly see Arbuthnot's Range, the north end of which bore N. 101., and the other part connected by a low range bore from N. 108 to N. 112. The country from north-west to north-east was open with the horizon, being covered with water and reeds, as far as the eye could distinguish; we saw immense numbers of wild ducks, many black swans, pelicans, and birds resembling the sea gannet: I altered my course to east, and shortly afterwards to south-east. I estimate the distance travelled this day to be eighteen miles. Being rather late, we were much at a loss to find a place dry enough to sleep on: the north end of Arbuthnot's Range bore N. 98. July 11.--Finding our efforts to travel in any direction north of east useless, I altered my course for the north end of Arbuthnot's Range. The country continuing nearly as yesterday, brushes and marshes alternately, having gone about twelve miles, the last quarter of a mile of which was at an almost imperceptible rise above the general level, I came to the edge of a river, the stream of which was thirty or fort yards wide, but the bed nearly one hundred yards, the banks being eight or nine feet high: I forded it in the middle of a very long reach bearing north and south, the stream clear, and running gently from the south, about three feet deep, over a fine sandy bottom. After crossing this river, I proceeded onwards about four miles, and halted on the edge of a brush, having travelled sixteen or seventeen miles. July 12.--After proceeding about four miles, we crossed a small stream from the south-east; the country perfectly level, not a perceptible rise in any direction, save Arbuthnot's Range: the space travelled over to-day was a complete marsh, the soil good, being clearly alluvial. It will be impossible for heavy loaded horses to walk over the country, traversed by us these last three days; the trouble we have had is more than can well be imagined. Travelled fifteen miles.
