After returning home, he continued his legal studies with Mr. Weeks until the July law term, in Sullivan county, in 1843, when he was admitted to the bar in the superior court of judicature in this state. He then went into company with Mr. Weeks at Canaan, where he remained till 1847, when he removed to Wentworth and opened an office there. He had been appointed solicitor for Grafton county in November, 1844, while at Canaan, and he at once commenced a lucrative business at Wentworth; was re-appointed solicitor in 1849 for five years more, thus holding the office for ten years, to 1854, performing the duties to the entire acceptance of the county and the people. He declined a re-appointment. In 1851 he was first elected a member of the legislature from Wentworth, and served as chairman of the committee on incorporations. The next year he was re-elected, and was made chairman of the judiciary committee; and in 1853 he was again a member, and was nominated with great unanimity and elected speaker of the house of representatives. He served with ability and impartiality and to the general acceptance of the members. The next winter a new man was to be selected as a candidate for senator in his district, and he was nominated, and was elected in March, in a close district, by about three hundred majority. He was elected president of the senate in 1854. He was renominated in the spring of 1855, but the Know-Nothing movement that year carried everything before it, and he was defeated, with nearly all the other Democratic nominees in the state.
