Camp 72 to 78.
22 December to 26 December 1860

Saturday, 22 December 1860.
At five minutes to five A.M. we left one of the most delightful camps we have had in the journey, and proceeded on the same course as before, north-west by north, across some high ridges of loose sand, many of which were partially clothed with porcupine grass. We found the ground much worse to travel over than any we have yet met with, as the ridges were exceedingly abrupt and steep on their eastern side, and although sloping gradually towards the west, were so honeycombed in some places by the burrows of rats, that the camels were continually in danger of falling. At a distance of about six miles, we descended from these ridges to undulating country of open box forest, where everything was green and fresh. There is an abundance of grass and salt bushes, and lots of birds of all descriptions. Several flocks of pigeons passed over our heads, making for a point a little to our right, where there is no doubt plenty of water, but we did not go off our course to look for it. Beyond the box forest, which keeps away to the right, we again entered the sand ridges, and at a distance of six miles, passed close to a dry salt lagoon, the ridges in the vicinity of which are less regular in their form and direction, and contain nodules of limestone. The ground in the flats and claypans near, has that encrusted surface that cracks under the pressure of the foot, and is a sure indication of saline deposits. At a distance of eight miles from the lagoon, we camped at the foot of a sand ridge, jutting out on the stony desert. I was rather disappointed, but not altogether surprised, to find the latter nothing more nor less than the stony rises that we had before met with, only on a larger scale and not quite as undulating. During the afternoon several crows came to feed on the plain. They came from an east-north-east direction, no doubt from a portion of the creek that flows though the forest that we left on our right. In the morning, as we were loading, a duck passed over, but it was too dark to see which way it went.

At five A.M. we struck out across the desert in a west-north-west direction. At four and a-half miles we crossed a sand ridge, and then returned to our north-west by north course. We found the ground not nearly as bad for travelling on as that between Bulloo and Cooper's Creek. In fact I do not know whether it arose from our exaggerated anticipation of horrors or not, but we thought it far from bad travelling ground, and as to pasture it is only the actually stony ground that is bare, and many a sheep run is in fact worse grazing ground than that. At fifteen miles we crossed another sand ridge, for several miles round which there is plenty of grass and fine salt bush. After crossing this ridge we descended to an earthy plain, where the ground was rather heavy, being in some places like pieces of slaked lime, and intersected by small watercourses; flocks of pigeons rose from amongst the salt bushes and polygonum; but all the creeks were dry, although marked by lines of box timber. Several gunyahs of the blacks were situated near a waterhole that had apparently contained water very lately, and heaps of grass were lying about the plains, from which they had beaten the seeds. We pushed on, hoping to find the creeks assuming an improved appearance, but they did not, and at one o'clock we halted, intending to travel through part of the night. About sunset, three flocks of pigeons passed over us, all going in the same direction, due north by compass, and passing over a ridge of sand in that direction. Not to have taken notice of such an occurrence would have been little short of a sin, so we determined to go eight or ten miles in that direction. Starting at seven o'clock P.M., we, at six miles, crossed the ridge over which the birds had flown, and came on a flat, subject to inundation. The ground was at first hard and even like the bottom of a claypan, but at a mile or so, we came on cracked earthy ground, intersected by numberless small channels running in all directions. At nine miles we reached the bed of a creek running from east to west: it was only bordered by polygonum bushes, but as there was no timber visible on the plains, we thought it safer to halt until daylight, for fear we should miss the water. At daylight, when we had saddled, a small quantity of timber could be seen at the point of a sand ridge about a mile and a half or two miles to the west of us, and on going there we found a fine creek, with a splendid sheet of water more than a mile long, and averaging nearly three chains broad: it is, however, only two or three feet deep in most parts.

We took a day of rest on Gray's Creek to celebrate Christmas. This was doubly pleasant, as we had never, in our most sanguine moments, anticipated finding such a delightful oasis in the desert. Our camp was really an agreeable place, for we had all the advantages of food and water, attending a position of a large creek or river, and were at the same time free from the annoyance of the numberless ants, flies, and mosquitoes that are invariably met with amongst timber or heavy scrub.

Tuesday, 25 December 1860.
We left Gray's Creek at half-past four A.M. and proceeded to cross the earthy rotten plains in the direction of Eyre's Creek. At a distance of about nine miles we reached some lines of trees and bushes which were visible from the top of the sand ridge at Gray's Creek. We found them growing on the banks of several small creeks which trend to the N. and N.N.W.; at a mile and a half further we crossed a small creek N.N.E., and joining the ones above mentioned. This creek contained abundance of water in small detached holes from fifty to a hundred links long, well shaded by steep banks and overhanging bushes. The water had a suspiciously transparent colour and a slight trace of brackishness, but the latter was scarcely perceptible. Near where the creek joined the holes is a sandhill and a dense mass of fine timber. The smoke of a fire indicated the presence of blacks, who soon made their appearance and followed us for some distance, beckoning us away to the N.E. We however continued our course N.W. by N., but at a distance of one mile and a half found that the creek did not come round as we expected, and that the fall of the water was in a direction nearly opposite to our course, or about west to east. We struck off north half west for a high sand ridge, from which we anticipated seeing whether it were worth while for us to follow the course of the creeks we had crossed. We were surprised to find all the watercourses on the plains trending rather to the south of east, and at a distance of three miles, after changing our course, and when we approached the sandhills towards which we had been steering, we were agreeably pulled up by a magnificent creek coming from the N.N.W., and running in the direction of the fire we had seen. We had now no choice but to change our course again, for we could not have crossed even if we had desired to do so. On following up the south bank of the creek we found it soon keeping a more northerly course than it had where we first struck it. This fact, together with its magnitude and general appearance, lessened the probability of its being Eyre's Creek, as seemed at first very likely from their relative positions and directions. The day being very hot and the camels tired from travelling over the earthy plains, which by-the-by are not nearly so bad as those at the head of Cooper's Creek, we camped at one P.M., having traced the creek up about five miles, not counting the bends. For the whole of this distance we found not a break or interruption of water, which appears to be very deep; the banks are from twenty to thirty feet above the water, and very steep; they are clothed near the water's edge with mint and other weeds, and on the top of each side there is a belt of box trees and various shrubs. The lower part of the creek is bounded towards the north by a high red sand ridge, and on the south side is an extensive plain, intersected by numerous water-courses, which drain off the water in flood-time. The greater portion of the plain is at present very bare, but the stalks of dry grass show that after rain or floods there will be a good crop on the harder and well drained portion; but I believe the loose earthy portion supports no vegetation at any time. The inclination of the ground from the edge of the creek-bank towards the plain is in many places very considerable; this I should take to indicate that the flooding is or has been at one time both frequent and regular.

Wednesday, 26 December 1860.
We started at five A.M., following up the creek from point to point of the bends. Its general course was at first north-by-west, but at about six miles, the sand ridge on the west closed in on it, and at this point it takes a turn to the N.N.E. for half a mile, and then comes around suddenly N.W. Up to this point it had been rather improving in appearance than otherwise, but in the bend to the N.W. the channel is very broad. Its bed being limestone rock and indurated clay, is for a space of five or six chains quite dry; then commences another waterhole, the creek keeping a little more towards north. We crossed the creek here and struck across the plain in a due north course, for we could see the line of timber coming up to the sand ridges in that direction. For from seven to eight miles we did not touch the creek, and the eastern sand ridge seceded to a distance, in some places of nearly three miles, from our line, leaving an immense extent of grassy plain between it and the creek. The distinctly marked feature on the lower part of this creek is that whenever the main creek is on one side of a plain, there is always a fine billibong on the opposite side, each of them almost invariably sticking close to the respective sand ridges. Before coming to the next bend of the creek a view from the top of a sandhill showed me that the creek received a large tributary from the N.W. at about two miles above where we had crossed it. A fine line of timber, running up to the N.W., joined an extensive tract of box forest, and the branch we were following was lost to view in a similar forest towards the north. The sand ridge was so abrupt when we came to the creek, that it was necessary to descend into its bed through one of the small ravines adjoining it. We found it partially run out, the bed being sand and strewed with nodules of lime, some of which were from one half to two feet long: they had apparently been formed in the sanddowns by infiltration.

A few botanical explanations have been appended. A few separate general remarks referring to this portion of the diary will be published, together with the meteorological notes to which they are contiguous. No other notes in reference to this portion of the journey are extant.
