A fluent and forcible speaker, he became a popular public lecturer, and a lay preacher of the Congregational Church. He was interested in the formation of responsible government in South Australia from its beginnings, and helped frame the 1855 Constitution. He unsuccessfully stood in the colony's first election, but entered the
South Australian Legislative Assembly in a by-election on 23 December 1857 for the seat of
Onkaparinga. He held that seat until 1870, when he was elected member for
Sturt, which he held until his death. He was Commissioner of Public Works in the 11-day
Francis Dutton Ministry of July 1863, and Commissioner of Crown Lands and immigration in the 16-day
John Hart Ministry of September–October 1868. As Commissioner of Crown Lands in the
Blyth Ministry from November 1871 to January 1872, he initiated a survey of the Northern Territory. He was acting Speaker in the assembly from 1872 until his death, and in 1876 he succeeded
John Carr as Chairman of Committees in the Assembly, a position he also held until his death on 25 October 1882. ==Public offices and philanthropy==
