"On the 25th we proceeded on our journey. I observed two new species of acacia near Yeinart. We mistook our road, and made our old station at Badgee-badgee, where we stopped to dine and feed our horses. I also found some curious aquatic plants in the pools of water among the rocks at Badgee-badgee. After dinner we succeeded with difficulty in tracing our road to our present station on the Mouran pool, the cart tracks being nearly obliterated by the trampling of the sheep. On arriving, we found that the exploring party had returned, and that Captain Scully and my son James had left, on their return, about half an hour before our arrival. The mutilated specimens of plants brought home by the party, and the accounts of some which were left behind, determined me to visit the new river myself, after botanizing a day in the vicinity of the station, where I found a fine glaucus-leaved Anadenia, and Mr. Gilbert got specimens of the blue kangaroo, and several small new quadrupeds -- one of them apparently a true rat, almost as large and mischievous as the Norway rat. Having got two natives, one of whom (Cabbinger) had been with the party to the north, we started on the 27th, and slept at a spring called Boorbarna. On the way I found a species of the common poison which I had not seen before, and a beautiful Conospermum, with pannicles of blue flowers varying to white. I was informed, by my son Johnston, that a plant like horehound, but with scarlet flowers, in tubes about an inch long, grew on the top of a stony hill to the north of the spring; I went and found the plant, which belongs to Scrophularinae; I also found a Manglesia, allied to Tridentifera, but having the leaves more divided; I also found a beautiful blue climbing plant, a species of Pronaya, on the top of the same hill. On the 28th, soon after setting out on our journey, I found two splendid species of everlasting flower, of which my son Johnston had been the original discoverer; one, with golden-yellow flowers varying to white, has the flowers in heads different from anything of the sort I have seen before, and will, I think, form a new genus of Compositae; and the other with pink flowers, growing two feet high, something like Lawrencella rosea, or Rhodanthe Manglesii, but if possible finer than either. In nine or ten miles to the north of Boorbarna, we crossed a curious tract of country, covered with what I considered a variety of quartz, which breaks with a conchoidal fracture, but it has very much the appearance of flint; in many places the pieces were large, with sharp angles; my sons complained that it injured their horses' feet, but by alighting, and leading our horses over the worse parts, I did not perceive any bad effects from it. This tract of country produces some interesting plants; a splendid Calathamnus, with leaves nine inches long, and showy scarlet flowers, was found by my youngest son, and I got plenty of specimens.
