S. ferocissimum, Lindl manuscripts; caule herbaceo erecto: aculeis confertissimis pugioniformibus arcuatis, foliis linearibus obtusis utrinque praesertim subtus furfuraceo-tomentosis aculeatissimis, pedunculis subtrifloris foliorum longitudine, calycibus inermibus.) A NEW GUIDE. On reaching the camp I found that Piper had fallen in with some natives, one of whom, an old man, undertook to conduct us to the Murrumbidgee in five days, assuring us that the Lachlan entered that river. This information, the dry state of the country, and the knowledge I had acquired of its principal features, determined me to follow the course of the Lachlan; and in the event of its soon uniting with the Murrumbidgee, to continue along the right bank of that river to its junction with the Murray, then to leave the bulk of our equipment, the carts and most of the cattle, and complete the survey of the Darling with a lighter party. April 29. We moved down the Lachlan, travelling in my former track, and we pitched our tents near the place where I had slept on the 26th, the cattle not being able to go further, from the softness of the ground after the rain. April 30. Following the same track, the party reached, at the distance of twelve miles, an angle of the river named Curwaddilly, at which there was a good pond, and here we encamped. From this point I obtained a bearing on Burradorgang, and it was the lowest station on the river which could be connected with my survey of the hills for, when Burradorgang sunk below the eastern horizon, a perfectly level line bounded our view on all sides. NATIVE DOG. May 1. Just as the party was leaving the ground a noise was heard in the rear, and two shots were fired before I could hasten to the spot. These I found had been inconsiderately fired by Jones our shepherd at a native dog belonging to our new guide and which had attacked the sheep. This circumstance was rather unfortunate, for our guide soon after fell behind, alleging to the party that he was ill. I knew however where to find water that day; and we proceeded to the fine pond which I was so fortunate as to discover on the 24th ultimo after our horses had suffered thirst for three days and two nights. Two young natives who had accompanied us for some days undertook to find water for a couple of journeys beyond this pond. The men caught in this friendly pool several good cod-perch (Gristes peelii) a fish surpassing, in my opinion, all others in Australia. As we crossed the plains this day I observed the natives eating a plant which grew in the hollows and we found it, when boiled, a very good vegetable. BRANCHES OF THE LACHLAN. May 2.
