Youngest Child of Byron Snopes

When Byron Snopes's four children step off the train in Jefferson, Chick describes the youngest as "a little one in a single garment down to its heels like a man's shirt made out of a flour- or meal-sack or maybe a scrap of an old tent" (378). He never indicates the sex of this child, perhaps because he cannot determine it himself - or perhaps to emphasize the strangeness of the four as a group. (All four children are mentioned in one phrase in The Mansion, as Byron's "four half-Snopes half-Apache Indian children, 327.)
