Dec. 1.--I rode to the eastward from our camp, to ascertain how far we were from the water-hole to which I had intended to conduct my party. After having ascended the gullies, and passed the low scrub and cypress-pine thicket which surrounds them, I came into the open forest, and soon found our tracks, and the little creek for which I had steered the day before. This creek, however, soon became a rocky gully, and joined a large creek, trending to the east and south-east. Disheartened and fatigued, I returned to the camp, resolved upon following down the course of the Boyd to the south-west, until I should come into a more open country. On my way back, I fell in with a new system of gullies, south of the creek I had left, and east of the creek on which our camp was, and which I had called "The Creek of the Ruined Castles," because high sandstone rocks, fissured and broken like pillars and walls and the high gates of the ruined castles of Germany, rise from the broad sandy summits of many hills on both sides of the valley. When I returned to the camp, Mr. Gilbert told me, that Mr. Roper and John Murphy had been on a mountain towards the head of the main creek, north-west from our camp, and that they had seen an open country before them. I therefore started, on the 2d December, with Mr. Gilbert to examine it. Our admiration of the valley increased at every step. The whole system of creeks and glens which join "Ruined Castle Creek," would form a most excellent cattle station. With the exception of the narrow gorge through which the main creek passes to join the Creek of Palms [Mr. Arrowsmith is of opinion that such a junction is improbable, if the author is alluding to the creek, called Palm Tree Creek, which he fell in with about 60 miles to the S.E.--ED.] to the south-east, which might be shut by a fence not thirty yards long; and of the passable ranges to the north-west, which lead into a new country, and which form the pass seen by Roper and Murphy, it is everywhere surrounded by impassable barriers. Beautiful grass, plenty of water in the lower part of the creek, and useful timber, unite to recommend this locality for such a purpose. The creeks to the east and south-east are also equally adapted for cattle stations. After passing a stony ridge covered with spotted-gum, from which the remarkable features of the country around us--the flat-topped mountain wall, the isolated pillars, the immense heaps of ruins towering over the summits of the mountains--were visible, we descended a slope of silver-leaved Ironbark, and came to a chain of water-holes falling to the east. Travelling in a north-westerly direction, and passing over an openly timbered country, for about two miles, we came to the division of the waters, on a slight ridge which seemed to connect two rather isolated ranges. We followed a watercourse to the northward, which, at seven miles [In the original drawing the watercourse is not more than two miles long, according to Mr.
