[Q]: Question: How long is the river in San Antonio where Jones drove cotton carrying wagon along the river? Passage:Walter "Wiley" Jones was born in Madison County in northeastern Georgia, on July 14, 1848. His parents were George Jones, a white planter, and Jones' slave, Anne, who had six children by George Jones: Matthew (who superintended the construction of the Wiley Jones Street Car Line), Thomas, Julia (wife of Ben Reed), Wiley, Taylor, and James (who managed many of Wiley's businesses). Wiley received his nickname because of his mischievous nature. At the age of five, he moved to Arkansas with his master and more than forty fellow slaves. They settled on the Governor Byrd plantation. George Jones died in 1858. Anne was called his wife in an 1889 biography of Jones, and she believed that George had promised to free herself and her children upon his death, but no manumission papers were found, and the family was kept as slaves and sold by the estate administer, Peter Finerty, to James Yell, a lawyer and planter in Pine Bluff. Jones worked as a houseboy and carriage driver for his new master. When Jones was ten, he was given to Yell's only son, Fountain Pitts Yell, on the occasion of Pitts Yell's marriage. Pitts was a state representative from 1860 to 1861. During the American Civil War, James Yell became a Major General of the Arkansas State Militia, and Pitts became a colonel in Company S of the 26th Arkansas Infantry Regiment in the Confederate Army. James Yell's was transferred to the Confederate States Army in the summer of 1861, and James left the service and moved to Texas. Jones served for Pitts during the war until Pitts' death in 1864 at the Battle of Pleasant Hill in Louisiana. Jones then joined James Yell and his family in Waco, Texas. There, he served as a porter in a mercantile house for one year. He was then hired to drive a wagon carrying cotton on a route along the Brazos River to San Antonio.
