By 1900, agriculture was the primary industry in Leake County. The Pearl River, located south of Carthage, was used to ship goods by steamboat to and from Jackson, the state capital . Although a railroad eventually ran through Carthage, it did not play a significant role in the development of the town. In 1914, the Merrill Brothers Logging Company built a logging railroad from Canton to McAfee, passing through Carthage. The line was taken over in 1927 by the Canton and Carthage Railroad, which then established commercial service to Carthage. The railroad was abandoned in 1960.
