From this side of the country, now that smoke no longer obscured the horizon, the outline of the great range was very bold, a lofty and very prominent pyramid crowning the most elevated south-western extremity, and forming as important a point for the survey of the country to the south-west as Mount Riddell presents for that towards the north-west. This point I named Mount Forbes after my friend Captain Forbes, 39th Regiment, then commanding the mounted police in New South Wales. That great range presents three principal heads, of which Mounts Riddell and Forbes are the northern and southern, the central or highest being Mount Lindesay. February 25. The party moved to the former encampment at Bullabalakit. In passing near the place where we set up our tents on quitting the canvas boats, I sought my buried specimens of rocks, and found that, for once, I had been able to hide so that the natives could not find. The treasure however consisted only of stones. My notes addressed to Mr. Finch, which I had hidden in trees as we advanced, never escaped their notice, neither had the provisions left for the use of my unfortunate courier Bombelli at the camp we now again occupied been suffered to remain where we had cautiously buried them. All the planks of sawn timber left at our old saw-pit had been collected in a heap and partly burnt. From the hill over the camp the view of the horizon was at length unobscured by smoke, and I found it possible to connect the distant points of the Nundewar range, with those then between us and the colony. Many hills which I had not before seen to the eastward were also visible. A heavy thundershower fell in the afternoon, and it was accompanied by a violent gale of wind which blew down Mr. White's tent, and very materially injured mine. TWO STRANGERS ON HORSEBACK. February 26. The party continued towards that portion of the Namoi at which we first arrived on advancing into those desolate regions, and we passed our old encampment beside The Barber's stockyard near Tangulda. After travelling about eight miles we met Mr. Brown of Wallamoul and his stockman on horseback. They had followed our track thus far on the information they had received from the native, Mr. Brown, and were proceeding to examine The Barber's stockyard. They informed us that our native guide confessed to them that his dread of the savage natives had induced him to return. The men caught several large cod (Peel's perch) one of which weighed 13 pounds. The river remained unswollen. February 27. As we continued our homeward journey Mr. Brown overtook us. He had found various brands of his cattle on portions of hide about the stock-yard. He assured me I should find no water at my old encampment where I intended again to halt, for that he had passed the previous night there without water. I however had the satisfaction to find as much as ever on the rocky bed of the watercourse where it is not so liable to be absorbed. ASCEND MOUNT WARROGA.
