He read law books extensively during his hours outside of school and in the early 1850s was appointed Deputy Clerk of the Supreme Court of Appeals at Lewisburg (now in West Virginia).
Being admitted to the bar shortly afterwards, he moved to Mercer County and began practice.
He became a member of the Readjuster Party and, in February, 1882, was elected to the Supreme Court of Appeals.
