Four years after his successful journey along the Bight, Forrest determined to explore the interior of Western Australia, and in so doing added greatly to the knowledge of that somewhat neglected State.

The success which had attended my previous expeditions, and the great encouragement received from the Government and public of each colony, made me wish to undertake another journey for the purpose of ascertaining whether a route from Western Australia to the advanced settlements of the Southern colony was practicable. I also hoped to contribute, if possible, towards the solution of the problem, What is the nature of the Interior? My first journey, when I succeeded in penetrating for about 600 miles into the unknown desert of Central Australia, had convinced me that, although there might, and doubtless would, be considerable difficulties to be encountered, there were no insuperable obstacles, except a probable failure in the supply of water. That certainly was the most formidable of all the difficulties that would no doubt have to be encountered; but on the previous journey the scarcity of water had been endured, not without privation and suffering, but without any very serious result.

Stuart's great feat of crossing the continent from south to north had been followed by other successful efforts in the same direction. Another result was the establishing a line of telegraph from Adelaide to Port Darwin. This might, therefore, be considered the eastern boundary of the unknown districts, and, moreover, was the point of departure for the South Australian expeditions in a westerly direction. It was also the limit I desired to reach, and reaching it, I should achieve the object I had so much at heart.

On the 18th of March, 1874, the expedition quitted Perth. The 19th was Sunday, and, according to practice, we rested. Every Sunday throughout the journey I read Divine Service, and, except making the daily observations, only work absolutely necessary was done. Whenever possible, we rested on Sunday, taking, if we could, a pigeon, a parrot, or other such game as might come in our way as special fare. Sunday's dinner was an institution for which, even in those inhospitable wilds, we had a great respect.

June 13th. About one o'clock Pierre saw a flock of emus coming to water, and went off to get a shot. Kennedy followed with the rifle. I climbed up on a small tree to watch them. I was surprised to hear natives' voices, and, looking towards the hills, I saw from forty to sixty natives running towards the camp, all plumed up and armed with spears and shields. I was cool, and told Sweeny to bring out the revolvers; descended from the tree and got my gun, and coo-ed to Pierre and Kennedy, who came running. By this time they were within sixty yards, and halted. One advanced to meet me, and stood twenty yards off: I made friendly signs; he did not appear very hostile. All at once, one from behind (probably a chief) came rushing forward, and made many feints to throw spears. He went through many manoeuvres, and gave a signal, when the whole number made a rush towards us, yelling and shouting, with their spears shipped. When within thirty yards, I gave the word to fire; we all fired as one man, only one report being heard. I think the natives got a few shots, but they all ran up the hill and there stood talking and haranguing and appearing very angry. We re-loaded our guns, and got everything ready for a second attack, which I was sure they would make. We were not long left in suspense. They all descended from the hill and came on slowly towards us. When they were about 150 yards off I fired my rifle, and we saw one of them fall, but he got up again and was assisted away. On examining the spot we found the ball had cut in two the two spears he was carrying; he also dropped his wommera, which was covered with blood. We could follow the blood-drops a long way over the stones. I am afraid he got a severe wound. My brother and Windich being away we were short-handed. The natives seem determined to take our lives and, therefore, I shall not hesitate to fire on them should they attack us again. I thus decide, and write in all humility, considering it a necessity, as the only way of saving our lives. I write this at 4 p.m., just after the occurrence, so that, should anything happen to us, my brother will know how and when it occurred. 5 p.m.—The natives appear to have made off. We intend sleeping in the thicket close to camp, and keeping a strict watch, so as to be ready for them should they return to the attack this evening. At 7.30 my brother and Windich returned, and were surprised to hear of our adventure. They had been over fifty miles from camp E.S.E., and had passed over some good feeding country, but had not found a drop of water. They and their horses had been over thirty hours without water.

June 14th, Sunday. The natives did not return to the attack last night. In looking round camp we found the traces of blood where one of the natives had been lying down. This must have been the foremost man, who was in the act of throwing his spear, and who urged the others on. Two therefore, at least, are wounded, and will have cause to remember the time they made their murderous attack upon us. We worked all day putting up a stone hut, ten by nine feet, and seven feet high, thatched with boughs. We finished it; it will make us safe at night. Being a very fair hut, it will be a great source of defence. Barometer 28.09; thermometer 68° at 5 p.m. Hope to have rain, as without it we cannot proceed.

July 3rd. Soon after starting, found a little water in a gully and gave our horses a drink. Ascended a spur of the range and had a good view ahead, and was very pleased with the prospect. Steering N.E. towards a large range about fifteen miles off, we found a great deal of spinnifex, although the country generally was thickly wooded. I rode Mission, who went along pretty well for about twelve miles, when Williams gave in again, and Mission soon did the same. For the next six miles to the range we had awful work, but managed with leading and driving to reach the range; spinnifex all the way and also on the top of it. I was very nearly knocked up myself, but ascended the range and had a very extensive view. Far to the N. and E. the horizon was as level and uniform as that of the sea; apparently spinnifex everywhere; no hills or ranges could be seen for a distance of quite thirty miles.

The prospect was very cheerless and disheartening. Windich went on the only horse not knocked up in order to find water for the horses. I followed after his tracks, leading the two poor done-up horses. With difficulty I could get them to walk. Over, and through the rough range I managed to pull them along and found sufficient water to give them a good drink, and camped on a small patch of rough grass in one of the gorges. Spinnifex everywhere; it is a most fearful country. We cannot proceed farther in this direction, and must return and meet the party, which I hope to do to-morrow night. We can only crawl along having to walk and lead the horses, or at least drag them. The party have been following us, only getting a little water from gullies, and there is very little to fall back on for over fifty miles. I will leave what I intend doing until I meet them. I am nearly knocked up again to-night; my boots have hurt my feet, but I am not yet disheartened.

[Forrest stayed in the Interior for nearly three more months.]

Sept. 26th. Got off early and followed the river (Hamilton) about two miles when it took a bend to the north, and as it was rather boggy near it, we left it, and steered about east and E.N.E. for about twenty miles over most miserable country without any grass. We camped on a small gully with a little water in it, and some old dry grass in a flat. The horses were very tired, not having had anything to eat for the last two or three days; and some showed signs of giving in; in fact, all weak and knocked up, and we had to handle them very carefully. For the first thirteen miles we passed many clay-pans full of water—water nearly everywhere—after which there was very little; and the rain does not appear to have been heavy to the east. The river is about a mile and a half north of us, and we have not seen it for some miles. Latitude 27° 9' south. Hope to reach the telegraph line to-morrow.
