1ST JANUARY, 1846.--A strong wind from N.E. blew during the day, and was very high at 11 A. M. The party were chiefly employed breaking in the young bullocks. At noon, nimbus, and some rain, tantalised us with the hope of a change; but the sky drew up into clouds of cumulus by the evening. The vegetation of the Bogan now recalled former labours: the ATRIPLEX SEMIBACCATA of Brown was a common straggling plant. 2D JANUARY.--The young cattle still occasioned delay. The morning was cloudy and promised rain; but a N.W. wind broke through the clouds, which resolved themselves into cirrostratus, and we had heat again. Besides the SALSOLA AUSTRALIS, we found a HALGANIA with lilac flowers, probably distinct from the species hitherto described, which are natives of the south-west coast. 3D JANUARY.--This morning the young cattle were yoked up with the old; and, after considerable delay, the party proceeded to some ponds in the Bogan about five miles lower down. We were now nearly opposite to the scene of Mr. Cunningham's disasters: I had recognised, amongst the first hills I saw when on the Goobang Creek, the hill which I had named Mount Juson, at his request, after the maiden name of his mother. The little pyramid of bushes was no longer there, but the name of Cunningham was so identified with the botanical history of almost all the shrubs in the very peculiar scenery of that part of the country, that no other monument seemed necessary. Other recollections recalled Cunningham to my mind; his barbarous murder, and the uncertainty which still hung over the actual circumstances attending it. The shrubs told indeed of Cunningham; of both brothers, both now dead; but neither the shrubs named by the one, nor the gloomy CASUARINOE trees that had witnessed the bloody deed, could tell more. There the ACACIA PENDULA, first discovered and described by Allan, could only "Like a weeping mourner stooping stand, For ever silent, and for ever sad." 4TH JANUARY.--The early cooler part of the morning was taken up with the young cattle. It was now but too obvious that this means of conveyance was likely to retard the journey to an extent that no pecuniary saving would compensate, as compared with light carts and horses. I proceeded forward in search of a deserted stockyard, called Tabbaratong, where some water was said still to remain. We found some mud and water only; although some that was excellent was found about two miles lower down the Bogan, late in the evening. We had crossed the neutral ground between the savage and the squatter. The advanced posts of an army are not better kept, and humiliating proofs that the white man had given way, were visible in the remains of dairies burnt down, stockyards in ruins, untrodden roads. We hoped to find within the territory of the native, ponds of clear water, unsoiled by cattle, and a surface on which we might track our own stray animals, without their being confused by the traces of others.
