The Boys' Life of Mark Twain — Albert Bigelow Paine

A long time ago, back in the early years of another century, a family named Clemens moved from eastern Tennessee to eastern Missouri-from a small, unheard-of place called Pall Mall, on Wolf River, to an equally small and unknown place called Florida, on a tiny river named the Salt. That was a far journey, in those days, for railway trains in 1835 had not reached the South and West, and John Clemens and his family traveled in an old two-horse barouche, with two extra riding-horses, on one of which rode the eldest child, Orion Clemens, a boy of ten, and on the other Jennie, a slave girl.
