The evidence
“He first commenced writing for the press in 1820, in the Providence G-azette, in a series of articles against the then pending Missouri Compromise, which attracted general attention. From that time onward, he wrote for various periodicals, as he felt constrained to do, on the living issues of the day — religious, moral and political.”
