Journals of Two Expeditions into the Interior of New South Wales

It is a historical book. The colony had been established many years before any successful attempt had been made to penetrate into the interior of the country, by crossing the range of hills, known to the colonists as the Blue Mountains: these mountains were considered as the boundary of the settlements westward, the country beyond them being deemed inaccessible. The year 1813 proving extremely dry, the grass was nearly all destroyed, and the water failed; the horned cattle suffered severely from this drought, and died in great numbers. It was at this period that three gentlemen, Lieutenant Lawson, of the Royal Veteran Company, Messrs. Blaxland, and William Wentworth, determined upon attempting a passage across these mountains, in hopes of finding a country which would afford support to their herds during this trying season. They crossed the Nepean River at Emu Plains, and ascending the first range of mountains, were entangled among gullies and deep ravines for a considerable time, insomuch that they began to despair of ultimate success.
