The true nature of the soil was fully developed by this day's rain. Being in dry weather a loose light sand without any apparent consistency, it was now discovered to have a small portion of loam mixed with it, which, without having the tenacity of clay, is sufficient to render it slimy and boggy: I am quite satisfied that two days' rain will at any time render this country impassable. The mortification and distress of mind I felt at being obliged to take a retrograde direction was heightened by seeing the horses struggling under loads far beyond their present powers, their labour rendered still more trying by the miserable country they were obliged to pass through. June 10.--Light rain during the night, the morning fair and pleasant: upon mature deliberation it was resolved to remain here until the 13th, for the purpose of refreshing the horses. I also determined to send a detachment on before us, to endeavour to find an eligible station for us to stop at, that we might proceed with more certainty. Mr. Cunningham named those thick brushes of eucalyptus that spread in every direction around us EUCALYPTUS DUMOSA, or the dwarf gum, as they never exceed twenty feet in height, and are generally from twelve to fifteen, spreading out into a bushy circle from their roots in such a manner that it is impossible to see farther than from one bush to the other; and these are very often united by a species of vine (cassytha), and the intermediate space covered with prickly wire-grass, rendering a passage through them equally painful and tedious The low ranges of hills which we quitted yesterday morning we named Disappointment Hills, from our not being able to penetrate beyond them to the north-west or west, and also from our not finding any water on them; our hopes being thus disappointed of penetrating into the interior in the direction that I intended when we quitted Mount Brogden. June 11.--A party set forward to the northward to explore our to-morrow's route, and to endeavour to find water at some eligible station. They returned about four o'clock, having proceeded eight or ten miles. Small holes of water were found in almost every gully. They saw several traces of the natives, but none recent: the dogs killed several kangaroo-rats, and some new species of plants were discovered. June 12.--Fine and clear. At eight o'clock set forward on our journey along the west side of Peel's range: we proceeded to the north, inclining westerly for about ten miles; the travelling for the horses very bad, the ground being extremely soft, the description of the country the same. The trees resembled bushes more than timber, being chiefly small cypresses, which is the prevailing wood. The grass where we stopped was very bad, but the quantity and quality of the water compensated for it. No recent marks of the natives having visited this part of the range.
