Henry Buck of Bucksport, Maine, moved to South Carolina in the 1820s to start lumber mills; Horry County had a significant timber industry with its cypress, pine and hardwood forests. One of Buck's mills was in what became Bucksport. Sawmills in Bucksport and Bucksville produced three million board feet of lumber annually by 1850. Buck used his ships to transport lumber to Georgetown and Charleston in South Carolina and as far away as New York City and Boston, and even to other countries. Lumber from Buck's operation even went into the construction of the Brooklyn Bridge. The Independent Republic Quarterly said, "By 1860, due largely to Bucksville and Bucksport, Horry District had become one of the five greatest timber-producing districts in the state."
