28th. Followed up the river. Fine pools for the first six miles, with numbers of ducks in them. After travelling about twenty miles we lost the river from keeping too far to the east, and following branches instead of the main branch--in fact, the river spreads out over beautifully-grassed plains for many miles. Fearing we should be without water, I pushed ahead, and after following a flat for about six miles, got to the main river, where there were large pools of brackish water. As it was getting late, returned in all haste, but could not find the party, they having struck westward. I got on the tracks after dark, and, after following them two miles, had to give it up and camp for the night, tying up my horse alongside. Neither food nor water, and no rug.

29th. I anxiously awaited daylight, and then followed on the tracks and overtook the party, encamped on the main branch of the river, with abundance of brackish water in the pools. Shot several cockatoos. From camp Mount Narryer bore North 211 degrees 30 minutes East magnetic, and Mount Dugel 225 degrees 15 minutes East magnetic. Camp is in latitude 26 degrees 6 minutes 12 seconds. Marked a tree with the letter F on right bank of river.

30th. Two of the horses could not be found till half-past twelve. After this we continued up the river over well-grassed country for about ten miles. Camped at a small pool of fresh water, in latitude 26 degrees 2 minutes 52 seconds, which we luckily found by tracking up natives. Large pools of salt water in river. Three walking and three riding every day. Set watch to-night, two hours each.

May 1st. Followed up river, keeping a little to the south of it for about fifteen miles. We camped on a splendid grassy flat, with a fine large pool of fresh water in it. Shot several ducks. This is the best camp we have had---plenty of grass and water--and I was very rejoiced to find the month commence so auspiciously. Barometer 29.10; thermometer 78 degrees at 5.30 p.m.; latitude 26 degrees 0 minutes 52 seconds South. Sighted Mount Gould, which bore North 58 degrees East magnetic. Marked a white gum-tree F 20, being 20th camp from Geraldton.

MEETING NATIVES.

2nd. Steered straight for Mount Gould, North 58 degrees East, for sixteen miles, when I found I had made an error, and that we had unknowingly crossed the river this morning. After examining the chart, I steered South-East towards Mount Hale and, striking the river, we followed along it a short distance and camped at some brackish water, Mount Hale bearing North 178 degrees East, and Mount Gould North 28 degrees East. Barometer 28.96; thermometer 77 degrees at 5.30 p.m. As Pierre was walking along, he suddenly turned round and saw four or five natives following. Being rather surprised, he frightened them by roughly saying, "What the devil you want here?" when they quickly made off. Windich and I then tried to speak to them, but could not find them. Latitude 25 degrees 57 minutes 32 seconds South; longitude about 117 degrees 20 minutes East.

3rd (Sunday). Went to summit of Mount Hale in company with Pierre, and after an hour's hard work reached it. It was very rough and difficult to ascend. The rocks were very magnetic; the view was extensive; indeed, the whole country was an extended plain. To the east, plains for at least thirty miles, when broken ranges were visible. Mount Gould to the North-North-East showed very remarkably. Mount Narryer range was visible. To the south, only one hill or range could be seen, while to the South-East broken ranges of granite were seen about thirty miles distant. Mount Hale is very lofty and rugged, and is composed of micaceous iron ore, with brown hematite; being magnetic, the compass was rendered useless. Returned about one o'clock. Windich and the others had been out searching for fresh water, and the former had seen three natives and had a talk with them. They did not appear frightened, but he could not make anything out of them. They found some good water. Barometer, at 6.30 p.m., 28.88; thermometer 76 degrees. Took observations for time and longitude. We are much in want of rain, and thought we should have had some, but the barometer is rising this evening. To-morrow we enter on country entirely unknown.

4th. Started at nine o'clock, and, travelling North-East for three miles, came to junction of river from Mount Gould, when we got some fresh water, also met two natives who were friendly, and they accompanied us. We took the south or main branch of river, and, steering a little south of east for about nine miles, over splendidly-grassed country, we camped on a small pool of fresh water on one of the courses of the river, Mount Gould bearing North 334 degrees 30 minutes East magnetic, and Mount Hale North 228 degrees 30 minutes East magnetic. Barometer 28.90; thermometer 76 degrees at 6 p.m.; latitude 25 degrees 54 minutes 37 seconds by Regulus. Marked a tree F 22, being 22nd camp from Geraldton.

LOFTY RANGES.

5th. We travelled up easterly along the river, which spreads out and has several channels, sometimes running for miles separately, then joining again. There were many fine fresh pools for the first four miles, after which they were all salt, and the river divided into so many channels that it was difficult to know the main river. After travelling about sixteen miles over fine grassy plains and flats, we were joined by seven natives, who had returned with the two who had left us this morning. They told us that there was no fresh water on the branch we were following, and we therefore followed them North 30 degrees East for seven miles (leaving the river to the southward), when they brought us to a small pool in a brook, where we camped, Mount Gould bearing North 285 degrees 30 minutes East magnetic, Mount Hale North 250 degrees East magnetic. Latitude 25 degrees 52 minutes from mean of two observations. Barometer 28.78; thermometer 77 degrees at 6 P.M.
