We set forward on a bearing of east-south-east, which I took to be the general direction of the Bogan, considering the position of Croker's range on the east, and that of the hills in the south, which I had traced. We travelled through forests of magnificent pine trees (Callitris pyramidalis) and crossing, at twelve miles further, a dry creek which appeared to be that of Tandogo, we encamped on the Bogan where there was a good pond of water. This abundance was the more acceptable as we had now left behind a part of the bed of this little river which for thirty miles was quite dry; the total want of water there being chiefly owing to the absorbent nature of the subsoil. We were now drawing towards its sources amongst the hills, and the same scarcity no longer prevailed. The height and girt of some of the callitris trees were very considerable. Thus we found that Australia contains some extensive forests of a very good substitute for the cedar of the colony (Cedrela toona, R. Br.) which is to be found only in some rocky gullies of the Coast range and is likely to be exhausted in a short time. The Acacia pendula adorned the immediate banks of the Bogan, but the grass was old and dry, being a crop of two years' growth; the cattle consequently did not feed well on it, and at last grew so weak that they could not be worked more than four hours, and thus our progress was limited to about eight miles a day. HERVEY'S RANGE IN SIGHT. September 7. We followed the bearing of 139 1/2 degrees as the direction in which we were most likely to find the Bogan, considering its general course and the position of the hills to the southward. After travelling eight miles a sight of the highest point of Hervey's range enabled me at once to determine my place on the map. IMPROVED APPEARANCE OF THE COUNTRY. We then proceeded on the bearing of 103 degrees, and made the Bogan at a spot where its banks were beautiful, and the grass of better quality than any we had seen for some time. The Acacia pendula grew there in company with the pine (or callitris) the casuarina and eucalyptus, besides many smaller trees in graceful groups, the surface being very smooth and park-like.
