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. LIVERPOOL. LANSDOWNE BRIDGE. Passing through Liverpool, which has a population of 600 inhabitants and is situated on the left bank of George's river, I arrived at three miles beyond that town at Lansdowne bridge, where the largest arch hitherto erected in Australia had been recently built by Mr. Lennox. The necessity for a permanent bridge over Prospect Creek arose from the failure of several wooden structures, to the great inconvenience of the public, this being really a creek rising and falling with the tide. The obstacle, and the steepness of the left bank, which was considerable, have been triumphantly surmounted by a noble arch of 110 feet span which carries the road at a very slight inclination to the level of the opposite bank. The bridge is wholly the work of men in irons who must have been fed, and must consequently have cost the public just as much if they had done nothing all the while; and it may be held up as a fair specimen of the great advantage of convict labour in such a country when applied to public works. The creek is navigable to this point and, stone being abundant and of good quality on the opposite side of George's river, one gang was advantageously employed in the quarry there while another was building the bridge. Mr. Lennox ably seconded my views in carrying these arrangements into effect. He contrived the cranes, superintended the stone cutting, and even taught the workmen; planned and erected the centres for the arches and finally completed the structure itself which had been opened to the public on the 26th of January.
