GOULBURN TOWNSHIP.

November 1.

Taking leave of my kind host at an early hour, I continued my ride, passing through the new township in which, although but few years had elapsed since I had sketched its streets on paper, a number of houses had already been built.  The Mulwary Ponds scarcely afford sufficient water of the supply of a large population there; but at the junction of this channel with the Wollondilly there is a deep reach not likely to be ever exhausted.

GREAT ROAD.

The road marked out between this township and Sydney led over a country shut up, as already stated, between the Wollondilly and the Shoalhaven rivers.  These streams are distant from each other at the narrowest part of the intervening surface about ten miles; and as each is bordered by deep ravines the middle portion of the country between them is naturally the most level, and this happens to be precisely in the direction most desirable for a general line of communication between Sydney and the most valuable parts of the colony to the southward.

TOWRANG HILL.

At a few miles from Goulburn the road passes by the foot of Towrang, a hill whose summit I had formerly cleared of timber, leaving only one tree.  I thus obtained an uninterrupted view of the distant horizon, and found the hill very useful afterwards in extending our survey from Jellore into the higher country around Lake George.  This hill consists chiefly of quartz rock.  At its base the new line leaves the original cart track which here crossed the Wollondilly twice.  I now found an intermediate road in use between the old track and my half-formed road which was still inaccessible at this point for want of a small bridge over Towrang Creek.

THE WOLLONDILLY.

The Wollondilly pursues its course to the left, passing under the southern extremity of Cockbundoon range, which extends about thirty miles in a straight line from north to south, and consists of sandstone dipping westward.  Near the Wollondilly and a few miles from Towrang a quarry of crystalline variegated marble has been recently wrought to a considerable extent, and chimney-pieces, tables, etc. now ornament most good houses at Sydney.  This rock occurs in blocks over greenstone, and has hitherto been found only in that spot.

WILD COUNTRY THROUGH WHICH IT FLOWS.

The channel of the Wollondilly continues open and accessible for a few miles lower down than this, but after it is joined by the Uringalla near Arthursleigh it sinks immediately into a deep ravine and is no longer accessible as above, the country to the westward of it being exceedingly wild and broken.  The scene it presented when I stood on the pic of Jellore in 1828 and commenced a general survey of this colony was of the most discouraging description.* A flat horizon to a surface cracked and hollowed out into the wildest ravines, deep and inaccessible; their sides, consisting of perpendicular rocky cliffs, afforded
