To the W.N.W. of Yass Plains there is a remarkable hill, called Pouni, remarkable not so much on account of its height, as of its commanding position. It had, I believe, already been ascended by one of the Surveyor-general's assistants. The impracticability of the country to the south of it, obliged us to pass under its opposite base, from which an open forest country extended to the northward. We had already recrossed the Yass River, and passed Mr. Barber's station, to that of Mr. Hume's father, at which we stopped for a short time. Both farms are well situated, the latter I should say, romantically so, it being immediately under Pouni, the hill we have noticed. The country around both was open, and both pasture and water were abundant. Mr. O'Brien had been kind enough to send one of the natives who frequented his station to escort us to his more advanced station upon the Morumbidgee. Had it not been for the assistance we received from this man, I should have had but little leisure for other duties: as it was however, there was no fear of the party going astray. This gave M'Leay and myself an opportunity of ascending Pouni, for the purpose of taking bearings; and how ever warm the exertion of the ascent made us, the view from the summit of the hill sufficiently repaid us, and the cool breeze that struck it, although imperceptible in the forest below, soon dried the perspiration from our brows. The scenery around us was certainly varied, yet many parts of it put me forcibly in mind of the dark and gloomy tracks over which my eye had wandered from similar elevations on the former journey. This was especially the case in looking to the north, towards which point the hills forming the right of the valley by which we had entered the plains, decreased so rapidly in height that they were lost in the general equality of the more remote country, almost ere they had reached abreast of my position. From E.S.E. to W.S.W. the face of the country was hilly, broken and irregular; forming deep ravines and precipitous glens, amid which I was well aware the Morumbidgee was still struggling for freedom; while mountains succeeded mountains in the back-ground, and were themselves overtopped by lofty and very distant peaks. To the eastward, however, the hills wore a more regular form, and were lightly covered with wood. The plains occupied the space between them and Pouni; and a smaller plain bore N.N.E. which, being embosomed in the forest, had hitherto escaped our notice. We overtook the party just as it cleared the open ground through which it had previously been moving. A barren scrub succeeded it for about eight miles. The soil in this scrub was light and sandy.
