In the 1915 edition of the Journal of American Folklore (Vol 28) p. 140 E. C. Perrow in an essay called "Songs and Rhymes From the South" gives a short, racist song lyric collected in 1909 from the recitation of a Mississippi Negro names Mrs. Brown that goes: (notice the 2nd verse)

WHITE MAN GOES TO COLLEGE
(From Mississippi; negroes; recitation of Mrs. Brown; 1909.)

White man goes tuh college, Nigger goes tuh fiel',
White man learn tuh read an' write, Nigger learn tuh steal.

Times is gittin' mighty ha'd, Money gittin' mighty scace;
Soon's I sell my cot'n "n co'n, I'se gwine tuh leave dis place.

White man go tuh meetin", Can't get up a smile;
Nigger go tuh meetin',
Boys, yuh hyeuh him shout a mile.
