Beyond Mount Torrens we entered the region which lies to the westward of the Macquarie range, and found several new plants, especially a very pretty Xerotes, with sweetly perfumed flowers, being a good deal like X. leucocephala, but with the leaves filamentous at the edges, and the male spikes interrupted.* We encamped on a deep pond at a bend of the Lachlan named Gonniguldury. I learnt from the old native guide who accompanied us from Regent's lake that they call those ponds of a river which never dry up quawy, a word which proved to be of use to us in descending the Lachlan. At this camp I found, by a careful observation of alpha and beta Centauri, that the magnetic variation was 8 degrees 56 minutes 15 seconds East. (*Footnote. X. typhina, Lindley manuscripts; acaulis, foliis longissimis angusto-linearibus margine laevibus filamentosis basi laceris, capitulis omnibus cylindraceis lanatis foemincis simplicibus masculis interruptis.) WALLANGOME. April 18. We continued along the riverbank passing quawys of various names as they were pointed out by our guide. We crossed the skirt of an extensive plain (Eeoappa) which brought in view just ahead of us a low ridge named Wallangome. At 8 1/2 miles we found the river close under the southern extremity of this hill, and its rocks so obstructed our passage that we were delayed an hour in clearing a way. I ascended that point nearest the river and determined its position by taking angles on various heights already laid down in my map such as Granard, Yarrarar, Mount Torrens, etc. The hill itself consisted chiefly of quartz rock, but at its base were water-worn blocks of quartzose sandstone containing pebbles of quartz, and they seemed to be the principal rock in the bed of the Lachlan. As we proceeded a low rocky ridge or extremity from Wallangome extended upwards of a mile along the river. Soon after we had passed a bend called Taralago we crossed the southern limits of a plain of which the local name is Nyaindurry, being bounded on the north-west by an isolated hill named Moriattu. After passing successively two similar points of the river we reached that of Gooda, where we encamped, the latitude observed being 33 degrees 23 minutes 3 seconds South. WILD CATTLE.
