August 21--At eight o'clock, accompanied by Mr. Evans and Mr. Cunningham, set out on our intended excursion down the Macquarie River. Crossing Bell's River in the valley, we came in a mile to where the steep rocky hills forming the west side of the vale advance their perpendicular cliffs directly over the river. These hills we soon rounded, and entered the vale north of them: I shall not in this place attempt to describe the rich and beautiful country that opened to our view in every direction. Alternate fine grazing hills, fertile flats and valleys, formed its general outline; whilst the river, an object to us of peculiar interest, was sometimes contracted to a width of from sixty to eighty feet between rocky cliffs of vast perpendicular height, and again expanded into noble and magnificent reaches of the width of at least two hundred feet, washing some of the richest tracts of land that can be found in any country; the banks were in those reaches low and shelving, and covered with pebbles, whilst even at the highest floods secondary banks restrained the river from doing the smallest damage: these secondary banks might be from six to eight hundred feet in width, and I think the highest marks of flood did not exceed twenty feet perpendicular. The rapids were usually formed by small stony islands, which. dividing the stream rendered it shoaler in those places than in others, but they never extended above one hundred yards, and were none of them fordable. Limestone of the best quality and of various species abounded; and it appeared to me to be as common as the other stone forming the hills, which was a fine and hard granite. We passed through this charming country for upwards of twelve miles, the course of the river during that time being nearly north, and from appearances we thought it must continue in that direction for a considerable distance farther. A perpendicular limestone rock overhanging the river terminated our excursion; adjoining to this rock (which was called Hove's Rock, from its being covered with a beautiful new species of hovia), a stratum of fine blue-slate was found. A little lower down, the bank on the east side was formed of perpendicular red earth cliffs at least sixty feet high, extending along the reach nearly three quarters of a mile; this bank was named Red Bank: a fine grassy hill thinly covered with wood rose eastward of it. The timber was unusually fine, consisting chiefly of very large and straight blue guns; beautiful large casuarina trees were occasionally growing at the very edge of the water. The tops and sides of the rocky precipices on the west side of Wellington Vale were clothed with cypress trees, which had all the appearance of the pinus silvestris, that adorns the mountains and glens of Scotland. It was nearly five o'clock before we returned to our tent, highly gratified with our day's excursion.
