2. Road over the Blue Mountains.—The most important result of Macquarie’s activity was the opening up of new country. He had quite a passion for road-making; and though, on his arrival in the colony, he found only forty-five miles of what were little better than bush tracks, yet, when he left, there were over three hundred miles of excellent and substantial roads spreading in all directions from Sydney. He marked out towns—such as Windsor, Richmond, and Castlereagh—in suitable places; then, by making roads to them, he encouraged the freed convicts to leave Sydney and form little communities inland. But his greatest achievement in the way of road-making was the highway across the Blue Mountains. This range had for years presented an insurmountable barrier. Many persons—including the intrepid Bass—had attempted to cross it, but in vain; the only one who succeeded even in penetrating far into that wild and rugged country was a gentleman called Caley, who stopped at the edge of an enormous precipice, where he could see no way of descending. But in 1813 three gentlemen—named Wentworth, Lawson, and Blaxland—succeeded in crossing. After laboriously piercing through the dense timber which covers some of the ranges, they traversed a wild and desolate country, sometimes crawling along naked precipices, sometimes fighting their way through wild ravines, but at length emerging on the beautiful plains to the west. On their return they found that by keeping constantly on the crest of a long spur, the road could be made much easier, and Governor Macquarie, stimulated by their report, sent Surveyor Evans to examine the pass. His opinion was favourable, and Macquarie lost no time in commencing to construct a road over the mountains. The difficulties in his way were immense; for fifty miles the course lay through the most rugged country, where yawning chasms had to be bridged, and oftentimes the solid rock had to be cut away.
