The rickety shell of the Bennett Grove School — Bulloch County's only known, extant one-room schoolhouse for black children from the long period when separate clearly wasn't equal — recently emerged from a thicket of bushes and small trees.Seven students from the Georgia Southern University Anthropological Society, led by a couple of their teachers and assisted by a few community volunteers, cleared the vegetation in a morning.This left the building leaning against a thin pine, as it has apparently done for years. Unpainted inside and out except for the door, the schoolhouse, built around 1918, never had electric lights or indoor plumbing. Using a bucket and pulley, children drew water from a still-existing shallow well.
