BREADALBANE PLAINS.

Doctor Gibson had kindly accompanied us to Breadalbane Plains. On the morning of the 18th he returned to Tyranna, and we pursued our journey, keeping mostly on a W.S.W. course. From the barren hills over which we passed, on leaving the plains, we descended upon an undulating country, and found a change of rock, as well as of vegetation, upon it. Granite and porphyry constituted its base. An open forest, on which the eucalyptus mannifera alone prevailed, lay on either side of us, and although the soil was coarse, and partook in a great measure of the decomposition of the rock it covered, there was no deficiency of grass. On the contrary, this part of the interior is decidedly well adapted for pasturing cattle.

THE LORN.

About 1 p.m. we passed Mr. Hume's station, with whom I remained for a short time. He had fixed his establishment on the banks of the Lorn, a small river, issuing from the broken country near Lake George, and now ascertained to be one of the largest branches of the Lachlan River. We had descended a barren pass of stringy bark scrub, on sandstone rock, a little before we reached Mr. Hume's station, but around it the same, open forest tract again prevailed. We crossed the Lorn, at 2 o'clock, leaving Mr. Broughton's farm upon our left, and passed through a broken country, which was very far from being deficient in pasture. We encamped on the side of a water-course, about 4 o'clock, having travelled about fifteen miles.

On the 19th, we observed no change in the soil or aspect of the country, for the first five miles. The eucalyptus mannifera was the most prevalent of the forest trees, and certainly its presence indicated a more flourishing state in the minor vegetation. At about five miles, however, from where we had slept, sandstone reappeared, and with it the barren scrub that usually grows upon a sandy and inhospitable soil. One of the drays was upset in its progress down a broken pass, where the road had been altogether neglected, and it was difficult to avoid accidents. Fortunately we suffered no further than in the delay that the necessity of unloading the dray, and reloading it, occasioned. Mr. O'Brien, an enterprising settler, who had pushed his flocks to the banks of the Morumbidgee, and who was proceeding to visit his several stations, overtook us in the midst of our troubles. We had already passed each other frequently on the road, but he now preceded me to his establishment at Yass; at which I proposed remaining for a day. We stopped about three miles short of the plains for the night, at the gorge of the pass through which we had latterly been advancing, and had gradually descended to a more open country. From the place at which we were temporarily delayed, and which is not inappropriately called the Devil's Pass, the road winds about between ranges, differing in every respect from any we had as yet noticed. The sides of the hills were steeper, and their summits sharper, than any we had crossed. They were thickly covered with eucalypti and brush, and, though based upon sandstone, were themselves of a schistose formation.

YASS PLAINS.

Yharr or Yass Plains were discovered by Mr. Hovel, and Mr. Hume, the companion of my journey down the Macquarie, in 1828. They take their name from the little river that flows along their north and north-west boundaries. They are surrounded on every side by forests, and excepting to the W.N.W., as a central point, by hill. Undulating, but naked themselves, they have the appearance of open downs, and are most admirably adapted for sheep-walks, not only in point of vegetation, but also, because their inequalities prevent their becoming swampy during the rainy season. They are from nine to twelve miles in length, and from five to seven in breadth, and although large masses of sandstone are scattered over them, a blue secondary limestone composes the general bed of the river, that was darker in colour and more compact than I had remarked the same kind of rock, either at Wellington Valley, or in the Shoal Haven Gully. I have no doubt that Yass Plains will ere long be wholly taken up as sheep-walks, and that their value to the grazier will in a great measure counterbalance its distance from the coast, or, more properly speaking, from the capital. Sheep I should imagine would thrive uncommonly well upon these plains, and would suffer less from distempers incidental to locality and to climate, than in many parts of the colony over which they are now wandering in thousands. And if the plains themselves do not afford extensive arable tracts, there is, at least, sufficient good land near the river to supply the wants of a numerous body of settlers.

HOSPITALITY OF MR. O'BRIEN.

We left Mr. O'Brien's station on the morning of the 21st, and, agreeably to his advice, determined on gaining the Morumbidgee, by a circuit to the N.W., rather than endanger the safety of the drays by entering the mountain passes to the westward. Mr. O'Brien, however, would not permit us to depart from his dwelling without taking away with us some further proofs of his hospitality. The party had pushed forward before I, or Mr. M'Leay, had mounted our horses; but on overtaking it, we found that eight fine wethers had been added to our stock of animals.
