The sandstone on the interior side extends to the summit of the trap range and its numerous ravines occasion the difficulties which have hitherto excluded wheel-carriages from access to the Illawarra.

LUPTON'S INN.

To cross a country so excavated is impossible except in certain directions, but the best lines these fastnesses admit of have been ascertained and marked out in connection with that for the great southern road, which ought to leave the present line at Lupton's Inn. I consider this the most important public work still necessary to complete the system of great roads planned by me in New South Wales; but I have not had means at my disposal hitherto for carrying into effect this portion of the general plan.

From Lupton's Inn Sydney bore north-east, yet I was obliged to turn with the present road towards the north-west and to travel eleven miles over unfavourable ground in a direction to the westward of north.

Having been engaged this day in examining the bridges and the work done along the whole line, Mr. Lambie accompanying me, I did not reach the house of my friend Macalister at Clifton until it was rather late, but at any hour I could be sure of a hearty welcome.

THE RAZORBACK.

November 3.

The Razorback range is a very remarkable feature in this part of the country. It is isolated, extending about eight miles in a general direction between west-north-west and east-south-east, being very level on some parts of the summit, and so very narrow in others, while the sides are also so steep, that the name it has obtained is descriptive enough.

FORD OF THE NEPEAN. CAMPBELLTOWN.

Around this trap-range lies the fertile district of the Cowpastures, watered by the Nepean river. On proceeding along the road towards Campbelltown we cross this river by a ford which has been paved with a causeway, and we thus enter the county of Cumberland. Here trap-rock still predominates, and the soil is good and appears well cultivated, but there is a saltness in the surface water which renders it at some seasons unfit for use. The line of great road as planned by me would pass by this township (now containing 400 inhabitants) and the town might then probably increase by extending towards George's river, a stream which would afford a permanent supply of good water.
