The country on its banks in this part presented also the same unvaried desert features that it did in the districts examined by us during the preceding year. The Murray, unlike the Darling, was a permanent river, and I thought it advisable to exhaust no more of my means in the survey of deserts but rather employ them and the time still at my disposal in exploring the sources of that river, according to my instructions and in hopes of discovering a better country. My anxiety about the safety of the depot brought me more speedily to this determination. During the wet and cold weather there might be less activity among the savage natives, but it was not probable that the tribe which had collected 500 men to attack Captain Sturt would be quiet in my rear after having lost some of their number. To be in detached parties amongst a savage population was perilous in proportion to the length of time we continued separate; and I did not feel warranted in exhausting all my means in order to attain, by a circuitous route, the point where my survey ought to have commenced; while a second duty for which the means now left were scarcely adequate remained to be performed. I had already reached a point far above where any boat could be taken, or even any heavy carts; and nothing was to be gained by following the river further. The natives were heard by Piper several times during the day's journey in the woods beyond the river, as if moving along the right bank in a route parallel with ours; but they did not appear near our camp, although their smoke was seen at a distance. RAINY MORNING. June 2. For several days the barometer had been falling and this morning the weather was rainy and cold. RETURN OF THE PARTY. After tracing the further course of the Darling for some distance and obtaining, during an interval of sunshine, a view from a sandhill which commanded a very extensive prospect to the northward, I commenced the retrograde movement along our route, which was but too deeply visible in the sand. From what Piper had said the men expected an engagement during the morning; and it was doubtful, on account of the wetness of the day, whether their pieces would go off if the natives came on; but fortunately we continued our journey unmolested. We reached our former encampment notwithstanding the unfavourable state of the ground, and again pitched our tents upon it. We found among the scrubs this day a new curious species of Baeckea with extremely small scattered leaves not larger than grains of millet, plano-convex and covered with pellucid dots.* (*Footnote.
