pack-horse go--one spear struck him and made him rush and jump about. This drew their attention from us for a moment; then, just as another flight of spears was let fly at us, we plunged forward on our horses, and fired our revolvers. I was horrified to find that mine would not go off, something was wrong with the cartridges, and, though I snapped it four times, not a single discharge took place. Fortunately Mr. Tietkens's went off all right, and what with that, and the pack-horse rushing wildly about, trying to get up to us, we drove the wretches off, for a time at least. They seemed far more alarmed at the horses than at us, of whom they did not seem to have any fear whatever. We induced them to retire for a bit, and we went on, after catching the packhorse and breaking about forty of their spears. I believe a wild Australian native would almost as soon be killed as have his spears destroyed. The country was now much rougher, the little grassy valleys having ceased, and we had to take to the hills. (ILLUSTRATION: ATTACK AT THE FARTHEST EAST.) While travelling along here we saw, having previously heard its rustle, one of those very large iguanas which exist in this part of the country. We had heard tales of their size and ferocity from the natives near the Peake (Telegraph Station); I believe they call them Parenties. The specimen we saw to-day was nearly black, and from head to tail over five feet long. I should very much have liked to catch him; he would make two or three good meals for both of us. Occasionally we got a glimpse of the Sugar-loaf. At nine miles from where we had encountered the enemy, we came to a bold, bare, rounded hill, and on ascending it, we saw immediately below us, that this hilly country ceased immediately to the east, but that it ran on south-easterly. Two or three small creeks were visible below, then a thick scrubby region set in, bounded exactly to the east by Mount Olga itself, which was sixty miles away. There was a large area of bare rock all about this hill, and in a crevice we got a little water and turned our horses out. While we were eating our dinner, Mr. Tietkens gave the alarm that the enemy was upon us again, and instantly we heard their discordant cries. The horses began to gallop off in hobbles. These wretches now seemed determined to destroy us, for, having considerably augmented their numbers, they swarmed around us on all sides. Two of our new assailants were of commanding stature, each being nearly tall enough to make two of Tietkens if not of me. These giants were not, however, the most forward in the onslaught. The horses galloped off a good way, with Tietkens running after them: in some trepidation lest my revolver should again play me false, though of course I had cleaned and re-loaded it, I prepared to defend the camp. The assailants immediately swarmed round me, those behind running up, howling, until the whole body were within thirty yards of me; then they came on more slowly.
