Thursday, 24th July. Thring Creek, entering the Marsh. Started at 7.40, course north. I have taken this course in order to make the sea-coast, which I suppose to be distant about eight miles and a half, as soon as possible; by this I hope to avoid the marsh. I shall travel along the beach to the north of the Adelaide. I did not inform any of the party except Thring and Auld, that I was so near to the sea, as I wished to give them a surprise on reaching it. Proceeded through a light soil, slightly elevated with a little ironstone on the surface, the volcanic rock cropping out occasionally; also some flats of black alluvial soil. The timber much smaller and more like scrub, showing that we are nearing the sea.

At eight miles and a half came upon a broad valley of black alluvial soil, covered with long grass; from this I can hear the wash of the sea. On the other side of the valley, which is rather more than a quarter of a mile wide, is growing a line of thick heavy bushes, very dense, showing that to be the boundary of the beach. Crossed the valley and entered the scrub, which was a complete network of vines. Stopped the horses to clear a way, whilst I advanced a few yards on to the beach, and was gratified and delighted to behold the water of the Indian Ocean in Van Diemen's Gulf, before the party with the horses knew anything of its proximity. Thring, who rode in advance of me, called out "The Sea!" which so took them all by surprise, and they were so astonished that he had to repeat the call before they fully understood what was meant. Then they immediately gave three long and hearty cheers. The beach is covered with a soft blue mud. It being ebb tide, I could see some distance; found it would be impossible for me to take the horses along it; I therefore kept them where I had halted them, and allowed half the party to come on to the beach and gratify themselves by a sight of the sea, while the other half remained to watch the horses until their return. I dipped my feet, and washed my face and hands in the sea, as I promised the late Governor, Sir Richard McDonnell, I would do if I reached it. The mud has nearly covered all the shells; we got a few, however. I could see no seaweed. There is a point of land some distance off, bearing 70°. After all the party had had some time on the beach, at which they were much pleased and gratified, they collected a few shells; I returned to the valley, where I had my initials (J.M.D.S.) cut on a large tree, as I did not intend, until I arrived at the mouth of the Adelaide, to put up my flag. Proceeded along the valley; at one mile and a half coming upon a small creek, with running water, and the valley being covered with beautiful green grass, I have camped to give the horses the benefit of it. Thus have I, through the instrumentality of Divine Providence, been led to accomplish the great object of the expedition, and take the whole party safely as witnesses to the fact, and through one of the finest countries man could wish to behold, good to the coast and with a stream of water within half a mile of the sea. From Newcastle water to the sea-beach, the main body of the horses have been only one night without water and then got it within the next day. If this country is settled, it will be one of the finest colonies under the Crown, suitable for the growth of any and everything—what a splendid country for producing cotton! Judging from the number of the pathways from the water to the beach, across the valley, the natives must be very numerous; we have not seen any, although we have passed many of their recent tracks and encampments. The cabbage and fan palm-trees have been very plentiful during to-day's journey down to this valley. This creek I named "Charles Creek," after the eldest son of John Chambers, Esq.; it is one by which some large bodies of springs discharge their surplus water into Van Diemen's Gulf; its banks are of soft mud, and boggy. Wind, south. Latitude, 12° 13´ 30".

Friday, 25th July. Charles Creek, Van Diemen's Gulf. I have sent Thring to the south-west to see if he can get round the marsh. If it is firm ground I shall endeavour to make the mouth of the river by that way. After a long search he has returned, and informs me that it is impracticable, being too boggy for the horses. As the great object of this expedition is now attained, and the mouth of the river already well known, I do not think it advisable to waste the strength of my horses in forcing them through, neither do I see what object I should gain by doing so; they have still a very long and fatiguing journey in recrossing the continent to Adelaide, and my health is so bad that I am unable to bear a long day's ride. I shall, therefore, cross this creek and see if I can get along by the sea-beach, or close to it. Started and had great difficulty in getting the horses over, though we cut a large quantity of grass, putting it on the banks and on logs of wood which were put into it. We had a number bogged, and I was nearly losing one of my best horses, and was obliged to have him pulled out with ropes; after the loss of some time we succeeded in getting them all over safely. At two miles came upon an open part of the beach, went on to it, and again found the mud quite impassable for horses. Stopped the party, as this travelling is too much for the horses, and, taking Thring with me, rode two miles to see if the ground was any firmer in places; found it very soft where the salt water had covered it, in others not so bad. Judging from the number of the shells banked up in different places, the sea must occasionally come over this. I saw at once that this would not do for the weak state in which my horses were, and I therefore returned to where I left the party, resolving to re-cross the continent to the City of Adelaide. I now had an open place cleared, and selecting one of the tallest trees, stripped it of its lower branches, and on its highest branch fixed my flag, the Union Jack, with my name sewn in the centre of it. When this was completed, the party gave three cheers, and Mr. Kekwick then addressed me, congratulating me on having completed this great and important undertaking, to which I replied. Mr. Waterhouse also spoke a few words on the same subject, and concluded with three cheers for the Queen, and three for the Prince of Wales. At one foot south from the foot of the tree is buried, about eight inches below the ground, an air-tight tin case, in which is a paper with the following notice:

"South Australian Great Northern Exploring Expedition. The exploring party, under the command of John McDouall Stuart arrived at this spot on the 25th day of July, 1862, having crossed the entire continent of Australia from the Southern to the Indian Ocean, passing through the centre. They left the City of Adelaide on the 26th day of October 1861, and the most northern station of the colony on 21st day of January, 1862. To commemorate this happy event, they have raised this flag bearing his name. All well. God Save the Queen!"

(Here follow the signatures of myself and party.)

As this bay has not been named, I have taken this opportunity of naming it "Chambers Bay," in honour of Miss Chambers, who kindly presented me with the flag which I have planted this day, and I hope this may be the first sign of the dawn of approaching civilization.

Exactly this day nine months the party left North Adelaide. Before leaving, between the hours of eleven and twelve o'clock, they had lunch at Mr. Chambers' house; John Bentham Neals, Esq., being present, proposed success to me, and wished I might plant the flag on the north-west coast. At the same hour of the day, nine months after, the nag was raised on the shores of Chambers Bay, Van Diemen Gulf. (On the bark of the tree on which the flag is placed is cut—DIG ONE FOOT, S.) We then bade farewell to the Indian Ocean, and returned to Charles Creek, where we had again great difficulty in getting the horses across, but it was at last accomplished without accident. We have passed numerous and recent tracks of natives to-day; they are still burning the country at some distance from the coast.

[Note. The memorandum left by Stuart on top of the Central Mountain runs as follows:]

John McDouall Stuart and party consisting of two men and himself arrived from Adelaide in the Centre of Australia on Saturday evening the twenty first day of April 1860, and have built this cone of stones and raised this flag to commemorate the event, on top of Mount Sturt; the centre is about two miles South South West at a small gum creek where there is a tree marked facing the south.
