Preacher Casy, (prefiguring Hazel Motes'"church of truth without Jesus Christ Crucified,"in Wiseblood) asks "Why do we got to hand it on to God or Jesus? Maybe....it's all man and women we love". A house is stolen and dragged across fields as soon as it is deserted. A stillborn child is sent down a flooded stream to rot in the streets to give it the tongue it never had.
