The day succeeding this adventure, we moved up the creek, which was, for the most part, even with the plain.  The country continued the same as that we had passed over from the junction, being subject to flood, and having patches of bulrushes and reeds upon it.  No change took place in the timber, but the line of acacia pendula, which forms the line of inundation, approached neater to us; nor was the mark of flood so high on the trunks of trees as below.  We halted, with abominable water, but excellent food for the animals in the plains behind us.  In continuing our journey, we found several changes take place in the appearance of the creek and its neighbourhood.  The former diminished in size, and at length separated into two distinct channels, choked up, for the most part, with dead bulrushes, but having a few green reeds in patches along it.  The flats on either side became slightly timbered, and blue gum was the prevailing tree.  Crossing one of the channels, we observed every appearance of our near approach to the marshes, the flats being intersected by many little water-runs, such as we had noticed at the bottom of them.  About noon we struck upon a body of reeds under the wood of eucalypti, below the second great morass, and keeping a little to our right to avoid them, fell shortly afterwards into our old track on the plain, upon which we continued to move, making the best of our way to the channel which had supplied our wants on our first return from the Darling.  It was now, however, quite dry, and we were obliged to push on further, to shorten the journey of the morrow.

Connection of Macquarie and Darling.

The result of our journey up the creek was particularly satisfactory, both to myself and Mr. Hume; since it cleared up every doubt that might have existed regarding the actual termination of the Macquarie, and enabled us to connect the flow of waters at so interesting and particular a point.  It will be seen by a reference to the chart, that the waters of the marshes, after trickling through the reeds, form a small creek, which carries off the superfluous part of them into Morrisset’s chain of ponds, which latter again falls into the Castlereagh, at about eight miles to the W.N.W. and all three join the Darling in a W. by N. direction, in lat. 30 degrees 52 minutes south and E. lon. 147 degrees 8 minutes at about 90 miles to the N.N.W. of Mount Harris, and about an equal distance to the E.S.E. of where we struck upon the last-mentioned river.  Thus it is evident that the Darling had considerably neared the eastern ranges, although it was still more than 150 miles from their base.  It was apparently coming from the N.E., and whether it has its sources in the mountains behind our distant settlements, or still farther to the northwards, is a question of curious speculation, although, as I have already stated, I am of opinion that none but tropical rains could supply the furious torrent that must sometimes rage in it.
