Explorer and pastoralist. Educated in London, trained as a surveyor and acquired agricultural interests. Journeyed to England in 1810 as a witness at Johnston's court martial. However, he returned to Sydney before the trial took place. In 1813 became part of the Lawson, Wentworth, Blaxland expedition as the first successful attempt to find a route across the Blue Mountains. His journal, with his accurate record of times and distances, enables the route to be precisely retraced. Governor Macquarie rewarded each explorer with a grant of 1000 acres on the west of the ranges. In 1819 he was appointed as commandant of the new settlement of Bathurst, occupying this post until retirment to 'Veteran's Hall' at Prospect. In the interim he held extensive pastoral interests and estates. Commissioned as a magistrate who entered freely into public life and on 10 October 1825 signed a letter approving trial by jury.
