Not Negro Songs.Most people fancy in a vague way that Stephen Foster’s songs are negroid or were inspired by the negro music. But Old Folks at Home” and the other Foster melodies are about as unlike negro music as anything could possibly be. That their words are ofien in negro dialect and express negro sentiments is simply a historic accident due to the fact that in Foster’s day the negro minstrels, real or “corked,” were tin* only means of bringing music before the public.
