Not being more than ten to fifteen miles from the sea, I steered north 330 degrees east magnetic. Starting at 8.5, and having ascended the high land, passed through a thick line of wattles and dwarf gum, growing on the eastern face of the limestone range, which forms the high barren range along this part of the coast. The country was covered with thick scrub, and some patches of gum and wattle thicket; about noon it was more open, and ascending an elevated sandy ridge, saw apparently a high range of hills extending north-north-west as far as Shark Bay, and terminated by a very abrupt and detached hill; but the excessive refraction caused by the heated and nearly level plain which intervened more than doubled their real height. We descended gradually over a succession of sandy hills or ridges till 2.0 p.m., when the lowest part of the plain was reached; we found it occupied by a small patch of spear-wood; the soil was hard dry clay, but on proceeding a little farther we found a patch of moist ground, encircled by a ridge of sand; at one foot deep we found water, but in such small quantity that we could only obtain sufficient for ourselves, and should have had to wait at least two hours to have given each horse only one gallon. Proceeding onwards, in hope of finding a more plentiful supply, we found the country became drier and full of circular hollows, filled with fine clumps of green wattle and a little grass; in one of these we bivouacked at 5.0, and dug six feet for water in red sand, but without any appearance of obtaining it even at double that depth.

REPULSED FOR WANT OF WATER.

1st October.

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.

Left our uncomfortable bivouac at 7.30 a.m.; steered south-east. Finding the horses scarcely able to travel from want of water, I took the strongest and rode over to the spot where we had obtained a little on the 30th September, to dig wells and have a supply ready, if it could be obtained in sufficient quantity; at 11.0 arrived, and found the wells we had dug nearly dry; by opening several trenches down to the rocks which lay about one and a half feet below the surface, the water oozed in, and when the party came up, at 12.0, there was about a gallon for each horse; taking off the packs, we commenced watering: four horses had received their small allowance, when it came to my horse Bob's turn; after drinking his share he marched off at a smart pace, which somewhat surprised us, as he started in the direction of what we had supposed to be nothing but a tea-tree scrub; on following him, we found the horse drinking at a small shallow pool of water in a hollow in the clay. This was a very fortunate discovery, as the trenches filled with water so slowly that a full supply could not have been obtained that night, and the horses had been sixty-five hours without water.

SAND PLAINS AND SCRUB. RETURN TO THE MURCHISON RIVER.

3rd October.

This morning Mr. Burges and myself started at 7.30 a.m. in a north-easterly course, to ascertain the practicability of proceeding in that direction, taking two of the strongest horses. After riding four hours over an open, scrubby sand-plain, with circular valleys, we again fell in with thickets of wattles so dense that, although burnt by the native fires about four years previous, they would have been impassable for the pack-horses; but, favoured by this circumstance, we penetrated the thicket in a north-north-west direction for about twelve miles. From one small sandy ridge we had an extensive view, but of a most discouraging nature; the whole country was one vast plain, covered with dense thickets and scrub as far as the eye could reach, except to the west-north-west, where rose a high and barren ridge, which would not have been visible but for excessive refraction, as it must have been more than twenty-five miles distant. The plain was still dotted over with the remarkable circular hollows or valleys which, by their extreme dryness, indicated a great depth of sandy soil, incapable of retaining water on the surface even for a short time, or any probability of our obtaining it by digging. We turned in disappointment towards the encampment, scarcely extricating ourselves from the thickets before it became dark. Having gained the sand-plain, we continued our return for several hours, steering by the stars, hoping by a night march to avoid the scorching effects of the sun, which at this season renders travelling over an extensive sandy plain very fatiguing. Having been more than eleven hours in the saddle, we halted for the night.
