| Abstract: |
Laboratory and experimental studies of glazed polish (corn gloss) on sickle edges, trillo teeth, hoe blades, and mealing stones indicate that this polish is analagous to modern lapidary polishes which are produced as submicroscopic frictional fusion zones by rubbing with soft powders. Frictional contact with opaline inclusions in grasses has produced corn gloss by fusion of flint surfaces and by fusion to them of dehydrated molecules of opal. The one-to-one equation of corn gloss to grasses has many implications to culture history. Among others, a previously unsuspected type of intense agriculture, closely adapted to conservation on prairie soils, is indicated for Hopewell, Middle Mississippi, and other American Indian cultures.
