Cooper's Creek to Carpentaria.
16 December to 21 December 1860

Sunday, 16 December 1860.
The horse having been shod and our reports finished, we started at 6.40 AM. for Eyre's Creek, the party consisting of Mr. Burke, myself, King, and Charley, having with us six camels, one horse, and three months' provisions. We followed down the creek to the point where the sandstone ranges cross the creek, and were accompanied to that place by Brahé, who would return to take charge of the depôt. Down to this point the banks of the creek are very rugged and stony, but there is a tolerable supply of grass and salt bush in the vicinity. A large tribe of blacks came pestering us to go to their camp and have a dance, which we declined. They were very troublesome, and nothing but the threat to shoot them will keep them away. They are, however, easily frightened; and, although fine-looking men, decidedly not of a warlike disposition. They show the greatest inclination to take whatever they can, but will run no unnecessary risk in so doing. They seldom carry any weapon, except a shield and a large kind of boomerang, which I believe they use for killing rats, &c. Sometimes, but very seldom, they have a large spear; reed spears seem to be quite unknown to them. They are undoubtedly a finer and better-looking race of men than the blacks on the Murray and Darling, and more peaceful; but in other respects I believe they will not compare favourably with them, for from the little we have seen of them, they appear to be mean-spirited and contemptible in every respect.

We continued to follow down the creek. Found its course very crooked, and the channel frequently dry for a considerable distance, and then forming into magnificent waterholes, abounding in water fowl of all kinds. The country on each side is more open than on the upper part of the creek. The soil on the plains is of a light earthy nature, supporting abundance of salt bush and grass. Most of the plains are lightly timbered, and the ground is finer and not cracked up as at the head of the creek. Left Camp 67 at ten minutes to six AM., having breakfasted before leaving. We followed the creek along from point to point, at first in a direction west-north-west for about twelve miles, then about north-west. At about noon we passed the last water, a short distance beyond which the creek runs out on a polygonum flat; but the timber was so large and dense that it deceived us into the belief that there was a continuation of the channel. On crossing the polygonum ground to where we expected to find the creek we became aware of our mistake. Not thinking it advisable to chance the existence of water ahead, we camped at the end of a large but shallow sheet of water in the sandy bed of the creek. The hole was about 150 links broad, and [blank] feet deep in most places. In many places the temperature of the water was almost incredibly high, which induced me to try it at several points. The mean of two on the shady side of the creek gave 97 4/10 degrees. As may be imagined this water tasted disagreeably warm, but we soon cooled some in water bags, and thinking that it would be interesting to know what we might call cool, I placed the thermometer in a pannikin containing some that appeared delightfully so, almost cold in fact; its temperature was, to our astonishment, 78 degrees. At half-past six, when a strong wind was blowing from south, and temperature of air had fallen to 80 degrees, the lowest temperature of water in the hose, that had been exposed to the full effect of evaporation for several hours was 72 degrees. This water for drinking appeared positively cold, and is too low a temperature to be pleasant under the circumstances. A remarkable southerly squall came on between five and six P.M., with every appearance of rain. The sky however soon cleared, but the wind continued to blow in a squally and irregular manner from the same quarter at evening.

Started at a quarter-past eight AM., leaving what seemed to be the end of Cooper's Creek. We took a course a little to the north of west, intending to try and obtain water in some of the creeks that Sturt mentioned that he had crossed, and at the same time to see whether they were connected with Cooper's Creek, as appeared most probable from the direction in which we found the latter running, and from the manner in which it had been breaking up into small channels, flowing across the plains in a north and north-north-west direction. We left on our right the flooded flats on which this branch of the creek runs out, and soon came to a series of sand ridges, the directions of which were between north half-west and north-north-west. The country is well grassed and supports plenty of salt bush. Many of the valleys are liable to be inundated by the overflow of the main creek. They have water-courses and polygonum flats bordered with box trees, but we met with no holes fit to hold a supply of water. At about ten miles we crossed a large earthy flat lightly timbered with box and gum. The ground was very bad for travelling on, being much cracked up and intersected by innumerable channels, which continually carried off the water of a large creek. Some of the valleys beyond this were very pretty, the ground being sound and covered with fresh plants, which made them look beautifully green. At fifteen miles we halted, where two large plains joined. Our attention had been attracted by some red-breasted cockatoos, pigeons, a crow, and several other birds, whose presence made us feel sure that there was water not far off; but our hopes were soon destroyed by finding a claypan just drying up. It contained just sufficient liquid to make the clay boggy. At ten minutes to seven P.M., we moved on, steering straight for Eyre's Creek, north-west by north, intending to make a good night's journey and avoid the heat of the day; but at a mile and a half we came to a creek which looked so well that we followed it for a short distance, and finding two or three waterholes of good milky water we camped for the night. This enabled me to secure an observation of the eclipse of Jupiter's (I) satellite, as well as some latitude observations. The night was so calm that I used the water as an horizon; but I find it much more satisfactory to take the mercury for several reasons.

We did not leave this camp until half-past eight, having delayed to refill the water-bags with the milky water, which all of us found to be a great treat again. It is certainly more pleasant to drink than the clear water, and at the same time more satisfying. Our course from here, north-west by north, took us through some pretty country, lightly timbered and well grassed. We could see the line of creek timber winding through the valley on our left. At a distance of five miles there was a bush fire on its banks, and beyond it the creek made a considerable bend to the south-west. At two miles farther we came in sight of a large lagoon bearing north by west, and at three miles more we camped on what would seem the same creek as last night, near where it enters the lagoon. The latter is of great extent and contains a large quantity of water, which swarms with wild fowl of every description. It is very shallow, but is surrounded by the most pleasing woodland scenery, and everything in the vicinity looks fresh and green. The creek near its junction with the lagoon contains some good waterholes five to six feet deep. They are found in a sandy alluvium which is very boggy when wet. There was a large camp of not less than forty or fifty blacks near where we stopped. They brought us presents of fish, for which we gave them some beads, and matches. These fish we found to be a most valuable addition to our rations. They were of the same kind as we had found elsewhere, but finer, being from nine to ten inches long, and two to three inches deep, and in such good condition that they might have been fried in their own fat. It is a remarkable fact, that these were the first blacks who have offered us any fish since we reached Cooper's' Creek.

Friday 21 December 1860.
We left Camp 70 at half-past five A .M., and tried to induce one or two of the blacks to go with us, but it was of no use. Keeping our former course we were pulled up at three miles by a fine lagoon, and then by the creek that flows into it; the latter being full of water, we were obliged to trace it a mile up before we could cross. I observed on its banks two wild plants of the, gourd or melon tribe, one much resembling a stunted cucumber the other, both in leaf and appearance of fruit, was very similar to a small model of a water melon. The latter plant I also found at Camp 68. On tasting the pulp of the newly-found fruit, which was about the size of a large pea, I found it to be so acrid that it was with difficulty that I removed the taste from my mouth. At eight or nine miles from where we crossed the creek we passed another large lagoon, leaving it two miles on our left, and shortly afterwards we saw one nearly as far on our right. This last we should have availed ourselves of, but that we expected to find water in a creek which we could see, by the timber lining its banks, flowed from the lagoon on our left and crossed our course a few miles ahead. We reached it at a distance of four or five miles farther, and found a splendid waterhole at which we camped. The creek at the point flows in a northerly direction through a large lightly timbered flat, on which it partially runs out. The ground is, however, sound and well clothed with grass and salsolaceous plants. Up to this point the country through which we have passed has been of the finest description for pastoral purposes. The grass and saltbush are everywhere abundant, and water is plentiful with every appearance of permanence. We met with porcupine grass, and only two sand ridges before reaching Camp 71.

Memo; Verbally transcribed from the Field Books of the late Mr Wills. Very few words, casually omitted in the author's manuscripts, have been added in brackets. 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.
