August 5.--The water for our breakfast drained our little well to the dregs. Hoping that we should be more fortunate in this day's route, at half past eight o'clock we again set forward, on the same point as yesterday. The first four miles of our course led through one of those dreadful scrubs of eucalyptus dumosa, and prickly grass, which we had often before experienced; it was on rather an elevated plain, and, exclusive of the difficulty of forcing a passage through it, was extremely boggy and distressing to the horses. After passing through it, the country for five or six miles farther was more open, the same elevated plain or level still continuing, being thinly studded with box and cypress trees, with abundance of acacia and other shrubs: the soil a loose, red, sandy loam. At the tenth mile we providentially found a small muddy hole of water which, bad as it was, refreshed both men and horses extremely; fearing, from the appearance of the country, that we should not find any water farther on, we filled our small keg, containing nearly three gallons, which would at all events free us from absolute want. We went four miles farther through the same desert country, when evening drawing on, and the small trees and shrubs becoming thicker, we thought it best to stop before we again encountered an eucalyptus brush; which not affording the smallest fodder for the horses, would, added to the want of water, render them in all probability unable to take either us or themselves out of the desert in which we were. The spot we halted on afforded some dry tea-grass and a few syngeneceous shrubs; and praying for a heavy dew to moisten them, we hoped the animals would not on the whole fare much worse than ourselves. The rain which had fallen while we were on the river was not perceptible here; indeed I think sufficient to deluge any other country must fall, before it is seen on the surface of such a soil as prevails in this part of New South Wales. A little rain renders it however so soft and slimy as to make it difficult to travel over; and I should conjecture, from the milky whiteness of the water in the holes we have seen, that it rests on a substratum of white clay three or four feet below the surface; the water holes at least had that bottom, although their margins were of the red, sandy loam before mentioned.
