This morning started at 7.55 a.m., and steering north-west, in hope of finding water, at 8.40 came on dense thickets of wattle, which extended at least seven or eight miles farther north; we therefore turned west to avoid them; at 9.30 changed the course to 300 degrees magnetic, and with great difficulty forced our way for two miles to a narrow strip of open ground; 12.40 p.m. arrived at the foot of the range of hills seen yesterday; found them to consist of limestone and sand, covered with thick scrub; between the hills were many nearly circular hollows filled with thickets of wattles; although the bottoms of the hollows were at least fifty feet below the lowest part of the ridges around them, they were quite dry, and afforded no hope of water even by digging; the country northward appeared even less likely to afford a supply, so much required, as it seemed to consist wholly of limestone and loose sand, without swamps or watercourses; the nearest spot at which we could hope to find it in this direction was the south part of Freycinet Harbour, distant, according to the charts, about thirty miles, and great doubt existed of the accuracy of it in this position (error having been found in some other parts of the coast-line); nor was it certain that we could find water on the coast, in which case the loss of our horses would be almost a necessary consequence, several of them showing extreme fatigue. The circumstances of the case required a prompt decision; I therefore ordered an immediate return towards the last spot where we had seen water. The whole party felt convinced of the necessity of returning, though with the greatest reluctance to do so, as it seemed to put an end to almost every hope of reaching the Gascoyne River. We followed our route back, and halted at 5.30 in a wattle thicket. A HORSE FINDS WATER. 2nd October.
