Carbon, nitrogen, and oxygen abundances are presented for seven mild barium stars and two classical barium stars. The mild barium stars do not show the carbon enhancement typical of the classical Ba II stars. The CNO abundances of the mild barium and normal G and K giants are identical. An s-process enhancement is confirmed for some of the mild barium stars.
