The Brazos Canal. Chartered in 1841, the Brazos Canal Company was the result of local landowners' efforts to build canals to connect inland plantations to Gulf shipping ports. Construction began in 1847 on a canal, referred to locally as the "slave ditch" because it was dug by the slaves of company owners. A one-mile section, twenty-four feet wide and three feet deep, took two years to complete. The project was soon abandoned. A rival company, the Galveston and Brazos Navigation Company, completed a canal between the Brazos River and Galveston Bay in 1856. Texas Sesquicentennial 1836 - 1986 #9535
