We arrived here on Saturday last, early in the afternoon. I had not time to write by the last post, which closed on the same evening. We are all in good health and spirits. The road we are about to take is not that which I had anticipated, namely, down the side of the Lower Darling, as we hear there is literally nothing for the horses to eat; so that we are going right across the country to the Darling, passing the Murray at this place. We leave Swan Hill about the middle of next week, and shall then be out of the colony of Victoria. We are expecting Professor Neumayer up shortly,-a scrap of paper today by the postman says tomorrow. I am rather disappointed at not having yet an assistant surveyor, but I hope he will arrive shortly. Letters in future had better be directed to the care of Dr Macadam, the secretary, as they will have to go by sea.
