He worked in his father’s grist mill until 1860, attending the common schools of his native town in his boyhood. He left home and removed to Cambridge, Mass., August 14, 1860, buying out what was then known as Buck’s Express. He conducted this business several years under its old name, then changed it to Sawin’s Express, which became one of the best known and most flourishing of the suburban express lines about Boston. His business was in transporting baggage and merchandise between Boston and Cambridge. He continued business until 1905, when he sold out to the Boston & Suburban Express Company, and retired from active business. He has resided in Cambridge, at No. 73 Brattle Street, his present home. He is a well-known and highly esteemed citizen.
