He was a Judge in Craven County, North Carolina in 1868, and was a member of the North Carolina House of Representatives from 1868 to 1870, thereafter resuming private practice in New Bern. He was a member of the North Carolina Senate from 1872 to 1874, and a Judge of the Superior Court in New Bern from 1874 to 1882.
